Introduction
In general, portal vein thrombosis poses a certain risk to life. The formation of portal vein thrombosis may lead to serious consequences, including liver failure and patient death; however, not all cases of portal vein thrombosis are severe. If timely treatment—such as medication, interventional therapy, or surgery—is provided, complete recovery is possible.
In general, portal vein thrombosis poses a certain risk to life. The specific analysis is as follows:
Portal vein thrombosis may lead to serious consequences, but not all cases are severe. If timely treatment—such as medication, interventional therapy, or surgery—is provided, complete recovery is possible.
However, if thrombosis occurs in the main trunk of the portal vein and persists for a prolonged period, it may eventually lead to portal hypertension and even cirrhosis. This can result in serious clinical complications such as upper gastrointestinal bleeding, hypersplenism, refractory ascites, or hepatic encephalopathy—all of which can be life-threatening and may ultimately progress to liver failure and patient death.
If the thrombus in the main portal vein extends downward into the superior mesenteric vein, it may cause widespread intestinal blood flow impairment and potentially lead to intestinal necrosis, requiring urgent surgical intervention. Extensive resection of necrotic bowel can result in short bowel syndrome, while intestinal necrosis itself may trigger intra-abdominal septic shock, which can also be fatal.
Patients are advised to seek medical attention promptly when experiencing any symptoms and to receive standardized treatment under the guidance of a physician, which helps promote recovery.
