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.
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).
Several types of pancreatectomies exist, including pancreaticoduodenectomy (Whipple procedure), distal pancreatectomy, segmental pancreatectomy, and total pancreatectomy. In total pancreatectomy, the gallbladder , distal stomach , a portion of the small intestine , associated lymph nodes and in certain cases the spleen are removed in addition ...
Tumors are still borderline resectable even if they involve the superior mesenteric or portal veins, gastroduodenal artery, superior mesenteric vein or colon. [17] Metastatic disease is another contradiction to surgery. It most often occurs in the peritoneum, in the liver, and in the omentum.
This interrupts the flow of blood through the hepatic artery and the portal vein, which helps to control bleeding from the liver. The common bile duct is also temporarily closed during this procedure. This can be achieved using: a large atraumatic hemostat (soft clamp). manual compression. vessel loop or umbilical tape. [7]
Vascular surgery is a surgical subspecialty in which vascular diseases involving the arteries, veins, or lymphatic vessels, are managed by medical therapy, minimally-invasive catheter procedures and surgical reconstruction.
Ultrasonography (US) is the first-line imaging technique for the diagnosis and follow-up of portal hypertension because it is non-invasive, low-cost and can be performed on-site. [17] A dilated portal vein (diameter of greater than 13 or 15 mm) is a sign of portal hypertension, with a sensitivity estimated at 12.5% or 40%. [18]
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.
