However, this study failed to support this theory; because spontaneous UVR was a slow process and unable to relieve portal vein pressure or improve the portal vein blood flow velocity. [2]. There were 8 cases of esophageal vein ligation (the procedure was performed according to the indications and contraindications, and the patient consent) in the UVR group and 14 cases in the non-UVR group, with no statistical significance between groups (16% vs. 14%, P=.744). The UVR diagnosis was made by ultrasound examination and was confirmed by computerized tomography scan. The UVR diagnosis was made by ultrasound examination and was confirmed by computerized tomography scan. Access to the portal venous system is obtainable via several approaches, including percutaneous transhepatic access, ileocecal vein access with laparotomy, access through a transjugular intrahepatic portosystemic shunt (TIPS), percutaneous transsplenic access, and percutaneous paraumbilical vein access [5, 6].Direct percutaneous access to the portal venous system is another option. The first major medical complications in the UVR and non-UVR patients. Identification of a patent paraumbilical vein by using Doppler sonography: importance in the diagnosis of portal hypertension. The newly recanalized and partially thrombosed paraumbilical vein was shown to have a maximal cross-sectional diameter of 3.8 cm . The main sites of portosystemic collateral pathways are: left gastric (see gastric varices) left gastric (coronary) vein and short gastric veins to distal esophageal veins. 3. For the non-UVR group, 50% of the patients were randomly included for the final analysis, to have a comparable sample size of the UVR group. Paraumbilical veins.

There was no difference in sex and age between the UVR and non-UVR patient groups. [3] The umbilical vein is potential and occluded, directly connects to the left branch of the portal vein through a layer of valve, undoing which by catheter will access to the portal vein system and allow clear radiographic display. General conditions (age, gender, etiology), clinical symptoms and signs, serum biochemical parameters, such as albumin, bilirubin, creatinine, international normalized ratio, and complications of cirrhosis including ascites, hepatic encephalopathy, gastrointestinal bleeding, esophageal and gastric varices (classified as Mild, Moderate and Severe according to Guidelines for The Diagnosis and Treatment of Esophageal and Gastric Variceal Bleeding in Cirrhotic Portal Hypertension), portal vein thrombosis were compared between groups. [7,8] Compared with transfemoral vein techniques, transunbilical vein techniques are simpler and easier to perform, cause only mild discomfort, less complications, and less portal thrombosis.[9]. [2015] 005, Second Affiliated Hospital of Nanchang University). The Child-Pugh classification was not statistically different in the UVR group and the non-UVR group (P>.401), suggesting that UVR did not affect the liver in Child-Pugh classification.

If there is a red vessel on color Doppler going out of the liver from the left portal vein (hepatofugal flow; towards the probe) in a patient with cirrhosis, that is what is the paraumbilical vein. Portal venous gas . Alexander MS, Blake RA, Gelman R. Visualization of a recanalized umbilical vein on hepatobiliary imaging with CT correlation. [16] It was suggested that UVR directs blood entering the systemic circulation without liver detoxification, which may increase HE risks. Diffuse PVT can develop into the cavernous transformation of the portal vein, limiting its treatment methods, with complications difficult to control, like bleeding and ascites. In considering the retrospective nature of the study and that informed consents were no longer available from many of the patients, the ethics board waived the requirement for informed consent (Certification No. Lutz HH, Gassler N, Tischendorf FW, Trautwein C, Tischendorf JJ.

Medical records of 247 patients with cirrhosis hospitalized at the Department of Gastroenterology of the Second Affiliated Hospital of Nanchang University from January 2012 to October 2015 were retrospectively screened. Early studies have shown that UVR does not decrease the formation of ascites. We performed four hepatic CT dynamic enhanced scans (i.e., equilibrium, artery venous, portal venous, and delay phase). AJR Am J Roentgenol. The vein of Burow is the third vein around the falciform ligament, but it does not enter the liver directly. In CB syndrome, the umbilical portion of the left portal vein feeds the paraumbilical vein that then leaves the liver and extends toward the umbilicus. Peng Y, Qi X, Dai J, Li H, Guo X. Child-Pugh versus MELD score for predicting the in-hospital mortality of acute upper gastrointestinal bleeding in liver cirrhosis. Paraumbilical veins can become enlarged in portal hypertension 3. Multistage classification statistics were performed using the MannWhitney U test. It can often be traced till umbilicus unless there is interfering bowel gas.Interestingly, hepatopetal flow (systemic to portal shunting) may be seen in cases of IVC thrombosis.

To the Editor. The paraumbilical vein is one of the portosystemic collaterals in patients with portal hypertension. However, opposite views posit that collateral circulation recanalization, such as an umbilical vein, splenorenal shunt, portosystemic shunt, will aggravate the development of esophageal varices, and increase the incidence of bleeding events and hepatic encephalopathy (HE). [23] Based on the phenomenon that collateral circulation increases the incidence of HE, clogging of collateral vessel recanalization may be used to treat HE, and the ascites and esophageal varices do not significantly aggravate the HE incidence. Spearman rank correlation was applied to analyze univariate statistics data. Search for Similar Articles Umbilical Vein Recanalization (UVR) may occur in patients with long-standing portal hypertension and liver cirrhosis. However, it terminates in the middle portion of the collapsed umbilical vein, although some small communicating branches are present between it and the inferior vein of Sappey, namely, the intercalary veins 1,2. HHS Vulnerability Disclosure, Help The umbilical vein is developed in the fetus and carries oxygenated blood from the placenta into the fetal liver. Other studies have shown that UVR increases the blood flow of the portal vein outflow tract to reduce the portal vein pressure, reducing risks of esophageal gastric varices, varicose vein rupture, and bleeding.

The HE rates for the UVR and non-UVR groups were 20% and 14% (Table (Table2).2). The very low-density filling defect can be seen on unenhanced scans. Portal hypertension is increased pressure in the portal vein the main vein that receives blood from the: The increased pressure is most often a symptom of liver disease and is most commonly caused by scarring in the liver ( cirrhosis ). Covered vs. uncovered stents for transjugular intrahepatic portosystemic shunt: a randomized controlled trial. Each analysis with Bonferroni's correction. Paraumbilical vein access is a reasonable approach to the portal vein in patients with a large amount of ascites or coagulation abnormalities. Spontaneous umbilical vein recanalization (UVR) may occur in patients with long-standing portal hypertension or liver cirrhosis, serving as a decompressive portosystemic shunt. [22]. If the shunt happens in a short period of time, such as transjugular intrahepatic portosystemic shunt (TIPS) and surgical shunt, the portal pressure is significantly reduced, which helps prevent hemorrhage and to improve ascites. Accessibility The paraumbilical vein occasionally leads to a varix around the umbilicus, a so-called caput medusa. 1985;144(3):549-53. congenital malformations and anatomical variants. A two-tailed P value<0.05 was considered statistically significant. [5]. Widening of hepatic fissure and porta hepatis is seen (black arrows); C: Ascending colon presents edematous wall thickening caused by congestion due to portal hypertension or . Percutaneous transretroperitoneal direct approach to occlude a major shunt in a patient with extrahepatic portal-systemic encephalopathy. fibers,andadipose tissues. Investigation: Qing Shi, XiaoLing Ye, Bin Ding, Kai Xiong. Pediatr Surg Int 2016;32:5538. This process is accompanied by the slow progress of cirrhosis. Plessier A, Darwish-Murad S, Hernandez-Guerra M, et al.. [17,18] Thus far, the clinical significance of UVR remains controversial. Early-phase cirrhosis is rarely diagnosed, instead, many patients are diagnosed in the decompensated period when their symptoms are complicated with portal hypertension, ascites, bleeding, and collateral circulation recanalization. It showed a dilated recanalized paraumbilical vein draining portal blood into external iliac veins . [25] Again, this was not found in our study. Studies on the esophageal and gastric variceal and the umbilical or paraumbilical patency are of great significance. The .gov means its official. There was no difference in the severe esophageal and gastric varices rate in the UVR group and the non-UVR group (48% vs 54%, P = .398 > .05), indicating that cirrhosis with UVR did not affect the formation and degree of esophageal and gastric varices. The complete recanalization rate of the portal vein was 57%, while TIPS did not reduce the risk of thrombosis,[34] which was similar to the results of the study. The inclusion criteria were according to the CT diagnosis and the clinical diagnostic criteria of cirrhosis;[19,20] Exclusion criteria included: hepatocellular carcinoma; complicated with other systemical diseases (such as heart, brain, lung, kidney, etc. We performed four hepatic CT dynamic enhanced scans (i.e., equilibrium, artery venous, portal venous, and delay phase). Gastroenterol Clin Biol 1982;6:31820. 1985;144(3):549-53. Disclaimer. recanalized umbilical vein is a sonographic finding that is common in patients with cirrhosis or portal hypertension. Ligamentum teres, central portion of falciform ligament, and recanalized umbilical vein. Spontaneous umbilical vein recanalization (UVR) may occur in patients with long-standing portal hypertension or liver cirrhosis, serving as a decompressive portosystemic shunt. [10,11] Collateral circulation recanalization may directly reduce the portal vein pressure, which reduces the incidence of esophageal variceal bleeding and ascites to a certain extent. In addition, alimentary tract hemorrhage incidence was 36.7% (55/150) in all patients, 32% (16/50) in the UVR group and 39% (39/100) in the non-UVR group, with no statistical significance between groups (P = .402, suggesting that UVR did not affect the occurrence of esophageal varices bleeding. Clinical characteristics of cirrhosis patients with umbilical vein recanalization: a retrospective analysis. The study is limited in the following aspects: we included a limited number of patients for analysis, and the observation window was a limited period of time. doi: 10.5114/pjr.2019.83135. [10]. The site is secure. For example, using the 1% of BWT guideline, a mouse that weighs 25 gm could have either 0.25 ml of blood withdrawn at a single sampling or a . Winslow ER, Brunt LM, Drebin JA, Soper NJ, Klingensmith ME. A discrepancy has been found in studies on the clinical significance of UVR. [23]. 8600 Rockville Pike [17]. It has been proven angiographically and histologically that these vessels actually are enlarged paraumbilical veins and not recanalized umbilical veins . [32,33] TIPS is a man-made portosystemic shunt, which was also an effective treatment for diffuse PVT. PVT is a common complication of cirrhosis, which may be related to portal hypertension caused by portal blood vein stasis, slow blood flow, and increased blood viscosity. Januszewicz MM, Haaburda-Rola M, Pruszyska-Wodarczyk I, Czachr-Zieliska A, Rowiski O. Pol J Radiol. As shown in Table 2, patients that were free of esophageal and gastric varices in the UVR group and the non-UVR groups accounted for 10% (5/50) and 11% (11/100), respectively (P > .05). The https:// ensures that you are connecting to the The authors have no conflicts of interest to disclose. UVR on CT often manifests as a network of collateral vessels connected to the left branch of the portal vein and then extended to the umbilicus. More recently, recanalised paraumbilical vein has been used as an access route for percutaneous embolisation of bleeding gastro-oesophageal and umbilical varices [60, 61]. A 3.1-g, 7.5-cm-long, completely occluded in vitro 3-dimensional model of acute CVST was fully recanalized within 8 min with a record-high lytic rate of 237.5 mg/min for acute bovine clot in vitro. [17,18] Thus far, the clinical significance of UVR remains controversial. Correspondence: Xiaoling Ye, The Department of Hepatology, First People Hospital of JiuJiang, JiangXi, China, 332000 (e-mail: [emailprotected]). Iwakiri Y, Shah V, Rockey DC. Discussion. https://www.renalfellow.org/tag/abhilash-koratala/. The recanalized paraumbilical vein (dashed arrow) is seen at the neck of the umbilical hernia. The black arrow refers to umbilical vein recanalization with an inner diameter of approximately 7.5mm. [19]. At analysis, we retrieved the medical records by two persons independently. [30,31] Theoretically, increased portal vein blood flow outflow and velocity in portal vein collateral circulation would reduce the risk of PVT, especially UVR increases the blood flow of portal vein trunk and left branch. 1989 Aug;23(4):208-10. Case 1: hepatic pseudolesion caused by veins of Sappey, View Mohammed Al Khader.O.Thabet's current disclosures, see full revision history and disclosures, doi:10.1148/radiographics.21.suppl_1.g01oc06s81, posterior left subphrenic (perisplenic) space, portal-systemic venous collateral pathways, nerve to quadratus femoris and inferior gemellus muscles, nerve to internal obturator and superior gemellus muscles. In our study, UVR did not affect Child-Pugh classification, the incidence of moderately severe ascites, the esophageal variceal bleeding rate, or PVT. G. Scott Gazelle, Sanjay Saini, Peter R. Mueller. The incidence of cavernous transformation of the portal vein was statistically significantly different, that there was 0 case in the UVR group and 8 cases in the non-UVR group (P = .04). Simple classification statistic materials used a 2 test or Fisher probability test in 2 2 table data. 28, 29, 30 If a patient with PHT develops a patent paraumbilical vein, flow often remains hepatopetal in the main PV despite elevation of the portosystemic . Indian J Radiol Imaging. Portal hypertension is a consequence of increased hepatic vascular resistance that can broadly be classified as . The newly recanalized and partially thrombosed paraumbilical vein was shown to have a maximal cross-sectional diameter of 3.8 cm . J Radiol Case Rep. 2010;4(10):14-20. (Fig.1B),1B), extending gradually into the splenic or superior mesenteric veins. Su ZZ, Shan H, Ke WM, He BJ, Zheng RQ. The early enhancement of the recanalized paraumbilical vein also suggests the presence of malignant arterioportal fistula. QS and KX contributed to the work equally. [7,8] Compared with transfemoral vein techniques, transunbilical vein techniques are simpler and easier to perform, cause only mild discomfort, less complications, and less portal thrombosis.[9]. BMJ 2015;351:h4263. During hospitalization, patient data including etiology, vital signs, clinical data, laboratory results, radiological features, treatment and outcomes were recorded into the electronic medical records by the physician.

Clipboard, Search History, and several other advanced features are temporarily unavailable. 2001;21 Spec No(suppl_1):S81-96. In our study, UVR did not affect Child-Pugh classification, the incidence of moderately severe ascites, the esophageal variceal bleeding rate, or PVT. Such dilated veins are seen in approximately 25% of patients with portal hypertension [1, 2]. Careers, Unable to load your collection due to an error. Usually noticed when you are imaging the portal vein as a part of venous congestion (#VExUS) assessment. Lafortune M, Constantin A, Breton G, Lgar A, Lavoie P. The Recanalized Umbilical Vein in Portal Hypertension: A Myth. A must-read article. Yoshimitsu K, Honda H, Kuroiwa T et al. In summary, the results show that UVR has no significant effect on the complications of cirrhosis or liver function, and it may not relieve portal pressure because it is a gradual process. usually accompanied by esophageal/paraesophageal varices (see below) How to cite this article: Shi Q, Xiong K, Ding B, Ye X. Lee HK, Park SJ, Yi BH, Yeon EK, Kim JH, Hong HS. At the time the article was created Donna D'Souza had no recorded disclosures. The demonstration of a vessel in the falciform ligament, traditionally presumed to be a reopened umbilical vein, is an important sonographic sign of portal hypertension. see full revision history and disclosures, transjugular intrahepatic portosystemic shunt (TIPS), World Health Organization 2001 classification of hepatic hydatid cysts, recurrent pyogenic (Oriental) cholangitis, combined hepatocellular and cholangiocarcinoma, inflammatory myofibroblastic tumor (inflammatory pseudotumor), portal vein thrombosis (acute and chronic), cavernous transformation of the portal vein, congenital extrahepatic portosystemic shunt classification, congenital intrahepatic portosystemic shunt classification, transient hepatic attenuation differences (THAD), transient hepatic intensity differences (THID), total anomalous pulmonary venous return (TAPVR), hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease), cystic pancreatic mass differential diagnosis, pancreatic perivascular epithelioid cell tumor (PEComa), pancreatic mature cystic teratoma (dermoid), revised Atlanta classification of acute pancreatitis, acute peripancreatic fluid collection (APFC), hypertriglyceridemia-induced pancreatitis, pancreatitis associated with cystic fibrosis, low phospholipid-associated cholelithiasis syndrome, diffuse gallbladder wall thickening (differential), focal gallbladder wall thickening (differential), ceftriaxone-associated gallbladder pseudolithiasis, biliary intraepithelial neoplasia (BilIN), intraductal papillary neoplasm of the bile duct (IPNB), intraductal tubulopapillary neoplasm (ITPN) of the bile duct, multiple biliary hamartomas (von Meyenburg complexes), 1.

[4,5] Computerized tomography (CT) scan can clearly show the splenic veins and mesenteric veins, the pressure gradient of portal and hepatic veins, and liver morphology, providing a basis for the diagnosis of liver diseases. Applicable To. In conclusion, we suggest transportal embolization as an effective treatment option for a pancreatic AVM, although the individual AVM vascular anatomy should be carefully evaluated before treatment. Fig. If the shunt happens in a short period of time, such as transjugular intrahepatic portosystemic shunt (TIPS) and surgical shunt, the portal pressure is significantly reduced, which helps prevent hemorrhage and to improve ascites. An electronic gastroscope (Fujitsu, 900x) was used to diagnose and classify esophageal and gastric varices.[21]. Pathology Early-phase cirrhosis is rarely diagnosed, instead, many patients are diagnosed in the decompensated period when their symptoms are complicated with portal hypertension, ascites, bleeding, and collateral circulation recanalization. The vessel involved is actually an enlarged paraumbilical vein. (Fig.11A),[7] which also allows direct measurement of the diameter of the UVR, the portal vein, spleen vein and superior mesenteric vein. HHS Vulnerability Disclosure, Help Sundaram V, Kowdley K. Management of chronic hepatitis B infection. Unusual Hemodynamics and Pseudolesions of the Noncirrhotic Liver at CT. Radiographics. 1 C). Child-Pugh classification and MELD scores were collected for indicators of liver functional reserve. [3] The HE rates for the UVR and non-UVR groups were 20% and 14% (Table 2). [23] Based on the phenomenon that collateral circulation increases the incidence of HE, clogging of collateral vessel recanalization may be used to treat HE, and the ascites and esophageal varices do not significantly aggravate the HE incidence. A portosystemic shunt is provided. The predictive value of successful catheterization based on preprocedural vein diameter was analyzed. I read the article titled "Macroaggregated albumin (MAA) injected in hepatic artery visualized in a recanalized paraumbilical vein" by Gupta et al 1 with great interest. Abdom Imaging. [2] Spontaneous UVR can also occur in other conditions like superior vena cava obstruction and rarely, in pancreatitis. Clinical significance of patent paraumbilical vein in patients with liver cirrhosis. The paraumbilical vein instead of the portal vein was punctured to decrease the risk of bleeding complications because she had coagulopathy and ascites. Kirby J, Cho K, Midia M. Image-Guided Intervention in Management of Complications of Portal Hypertension: More Than TIPS for Success. 5. For further assessment, a triple-phase (non-enhanced, arterial and portal venous) contrast-enhanced CT scan of the liver was performed. PVT is a common complication of cirrhosis, which may be related to portal hypertension caused by portal blood vein stasis, slow blood flow, and increased blood viscosity. The paraumbilical veins (inferior veins of Sappey) in PHT connect the anterior parietal veins like the superior and inferior epigastric veins in rectus sheath and thoracoepigastric vein in subcutaneous tissue at the umbilicus with the left branch of PV. [31]. It can occur when the veins leading in to or out of the liver are blocked, or as a . Dao T, Bouvard N. Prevalence of spontaneous hepatofugal portal flow in liver cirrhosis. These veins include Burrow's veins, and the veins of Sappey - superior veins of Sappey and the inferior veins of Sappey. Despite a marginal increase in attenuation between the arterial and portal .

This work was supported by China National Nature Science Foundation (grant number: 91029720) has been removed from the funding information. The diameters of the portal vein, splenic vein, superior mesenteric vein, and umbilical vein measured by abdominal CT were also compared. They are composed of Burows veins and Sappeys inferior and superior veins. Spontaneous recanalization of the paraumbilical veins as a consequence of pancreatitis in a patient with an otherwise normal liver is, however, a rare entity. Portal hypertension. [6] The umbilical vein is used in diagnostic and treatment techniques, such as trans-umbilical vein hepatic venous pressure measurement, trans-umbilical vein hepatoportography, trans-umbilical vein perfusion chemotherapy and chemoembolization, trans-umbilical portosystemic shunt, trans-umbilical vein insertion into the subcutaneous buried chemotherapy pumps, etc. Perarnau JM, Le Gouge A, Nicolas C, et al. This vessel was sought in 200 umbilicoportographies (all portal hypertensive) and in 41 autopsy-dissected falciform ligaments (34 normal and seven cirrhotic). It is difficult to control bleeding or ascites during these treatments. In patients with known cirrhosis, Doppler ultrasound has a specificity greater than 80% for CSPH.

For statistical analysis, a t-test was applied to normally distributed measurement data and the MannWhitney U test was applied to non-normally distributed measurement data. Materials and methods: Between July 2008 and Jan 2014, percutaneous access via the recanalized paraumbilical vein for varix embolization was attempted in seven patients with variceal bleeding. Punamiya S. Interventional Radiology in the Management of Portal Hypertension. Vessel occlusion . The umbilical vein diameter was 9.894.73, with a range of 4.5 mm to 26.5mm.

Influence of paraumbilical vein patency on the portal hemodynamics of patients with cirrhosis. [12]. Statistics of portal vein, splenic vein, and superior mesenteric vein diameter. A reopened umbilical vein was never found. [30,31] Theoretically, increased portal vein blood flow outflow and velocity in portal vein collateral circulation would reduce the risk of PVT, especially UVR increases the blood flow of portal vein trunk and left branch. Antegrade embolization via one of the paraumbilical veins was planned.
