Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver. The mortality rate is approximately 1 in 10.
Preoperative PVE is a very well tolerated procedure with extremely low mortality rates (0.1 percent) and technical failure rates (0.4 percent). [3] Complication rates from the procedure are low as well (2–3 percent) and include portal vein thrombosis, liver infarction, necrosis, infection, pneumothorax, and other risks as listed above. [3]
In patients with malignancy-associated hypercoagulable states, the blood may spontaneously form clots in the portal vessels (portal vein thrombosis), the deep veins of the limbs (deep vein thrombosis), or the superficial veins (superficial vein thrombosis) anywhere on the body.

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.
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] On Doppler ultrasonography , a slow velocity of <16 cm/s in addition to dilatation in the main portal vein are diagnostic of portal hypertension. [ 19 ]
