OBJECTIVE
To study the angioarchitecture of the inflow tracts of portal blood to esophageal and gastric varices in portal hypertension. Estimation of feasibility and laboriousness assessment of their selective endovascular embolization to control of variceal bleeding.
MATERIAL AND METHODS
Series of phlebo-portograms performed at the stage of direct portography during transjugular intrahepatic portosystemic shunting (TIPS) in 202 patients with cirrhotic portal hypertension were analyzed. The angioarchitecture of the inflow tracts to the esophageal and gastric varices (left, posterior and short gastric veins) was studied. The details of their branching after selective catheterization with subsequent contrast enhancement have also been studied.
RESULTS
The anatomical features of the tributaries of portal and splenic veins involved in the formation of varicose esophagogastric transformation in patients with bleeding caused by portal hypertension were analyzed. The responsibility of the left, posterior and short gastric veins for the formation of varices was established in 100%, 67.5% and 16.2% of patients, respectively. Their course is characterized by extensive branching and anastomosing in variceal zone. These facts demand to perform selective embolization of all identified inflow tracts to the varices.
CONCLUSION
The features of angioarchitecture of inflow tracts to esophagogastric varices in patients with variceal bleeding caused by portal hypertension were analyzed. The responsibility of the left, posterior and short gastric veins for the formation of nodes was established in 100%, 67.5% and 16.2% of patients, respectively. It course is characterized by extensive branching and anastomosing in variceal zone. The established facts demand to perform selective embolization of all identified inflow tracts to the varices.
