A pancreaticoduodenectomy, also known as a Whipple procedure, is a major surgical operation most often performed to remove cancerous tumours from the head of the pancreas. [2] It is also used for the treatment of pancreatic or duodenal trauma, or chronic pancreatitis. [2]

Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible. The great saphenous vein is most
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.
Arterial and venous disease treatment by angiography, stenting, and non-operative varicose vein treatment sclerotherapy, endovenous laser treatment have largely replaced major surgery in many first world countries. These procedures provide reasonable outcomes that are comparable to surgery with the advantage of short hospital stay (day or ...
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 first is the use of beta-blockers, which reduce portal pressures. Non-selective beta blockers (such as propranolol and nadolol) have been used to decrease the pressure of the portal vein in patients with esophageal varices, and have been shown to regress portal hypertensive gastropathy that has been worsened by medical treatment of varices. [5]
In situations where portal pressures increase, such as with cirrhosis, there is dilation of veins in the anastomosis, leading to esophageal varices. [3] Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure. Splenectomy can cure the variceal bleeding due to splenic vein thrombosis.
