In cases where less than 50% of the vessel is involved, vascular surgeons remove the involved portion of the vessel, and repair the residual artery or vein. [16] Tumors are still borderline resectable even if they involve the superior mesenteric or portal veins, gastroduodenal artery, superior mesenteric vein or colon. [17]

The portal vein is not a true vein, because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system , one of three portal venous systems in the human body; the others being the hypophyseal and renal portal systems.
In medicine, a distal splenorenal shunt procedure (DSRS), also splenorenal shunt procedure and Warren shunt, [1] is a surgical procedure in which the distal splenic vein (a part of the portal venous system) is attached to the left renal vein (a part of the systemic venous system).
The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery.
Portal vein embolization (PVE) is a preoperative procedure performed in interventional radiology to initiate hypertrophy of the anticipated future liver remnant a couple weeks prior to a major liver resection procedure. The procedure involves injecting the right or left portal vein with embolic material to occlude portal blood flow.
The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
A portacaval anastomosis or portocaval anastomosis is a specific type of circulatory anastomosis that occurs between the veins of the portal circulation and the vena cava, thus forming one of the principal types of portasystemic anastomosis or portosystemic anastomosis, as it connects the portal circulation to the systemic circulation, providing an alternative pathway for the blood.
