Anatomic Variations of the Right Portal Vein: Prevalence, Imaging Features, and Implications for Successful Transjugular Intrahepatic Portosystemic Shunt Creation
نویسندگان
چکیده
Given the widespread use of transjugular intrahepatic portosystemic shunt (TIPS) creation for the treatment of portal hypertensive complications, a working knowledge of portal venous anatomy is critical for interventional radiologists. The right portal vein - which is most commonly accessed during TIPS - is subject to various anatomic variants that may potentially impact procedure success. This pictorial essay characterizes the anatomic patterns of the right portal vein branching in terms of type and frequency based on case series review. The work also explains the potential procedural implications of the right portal vein anatomic variations as they pertain to TIPS technical success.

Transjugular intrahepatic portosystemic shunt performed in a 2-year-old infant with uncontrollable intestinal bleeding.
Although transjugular intrahepatic portosystemic shunt (TIPS) is widely accepted in adults, there have been few successful reports in infants. The authors describe a 2-year-old boy with postoperative biliary atresia who underwent TIPS for uncontrollable lower intestinal bleeding and achieved hemostasis. Massive melena developed, which was not controlled by conservative therapy and devasculariza...
متن کاملMesocaval Shunt Creation for Jejunal Variceal Bleeding with Chronic Portal Vein Thrombosis
The creation of transjugular intrahepatic portosystemic shunt (TIPS) is a widely performed technique to relieve portal hypertension, and to manage recurrent variceal bleeding and refractory ascites in patients where medical and/or endoscopic treatments have failed. However, portosystemic shunt creation can be challenging in the presence of chronic portal vein occlusion. In this case report, we ...
متن کاملA Method to Prevent Life-threatening Intraperitoneal Bleeding During Transjugular Intrahepatic Portosystemic Shunt Creation
Purpose : To prevent intraperitoneal bleeding, it is critical that the extrahepatic portal vein should not be punctured during transjugular intrahepatic portosystemic shunt(TIPS). There has, however, been no procedure for defining the anatomic relationship between the hepatic capsule and the portal vein segment before shunt formation. To avoid a possibly catastrophic outcome of extrahepatic por...

BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) in patients with portal hypertension may be considered as a rescue therapy in case of recurrent variceal bleeding or failure of endoscopic management. CASE REPORTS We present a case of a patient with massive gastroesophageal variceal bleeding refractory to numerous endoscopic treatments in which TIPS was considered in an attempt ...
متن کاملRecanalization of an Occluded Intrahepatic Portosystemic Covered Stent via the Percutaneous Transhepatic Approach
A 41-year-old woman with liver cirrhosis had recurrent portal hypertension and bleeding from esophageal varices due to complete occlusion of a previously inserted transjugular intrahepatic portosystemic shunt stent. Because recanalization of the stent by the transjugular approach was unsuccessful, ultrasound-guided entry to the splenic vein and portal vein was used. After catheter-directed intr...
