Endovascular techniques for portal hypertension are minimally invasive procedures used to treat increased pressure in the portal vein, which carries blood from the digestive organs to the liver. These techniques typically involve stenting to open narrowed or blocked veins, or embolization to control bleeding from varices. Endovascular procedures provide a safer alternative to traditional surgery and are effective in reducing the risk of complications like variceal bleeding.

These techniques are critical in treating portal hypertension, improving blood flow, and preventing liver damage or failure.
