Which veins are involved in the surgical bypass procedure for portal hypertension?

Splenic vein and inferior vena cava
Mesenteric vein and aorta
Hepatic vein and right atrium
Portal vein and inferior vena cava

The correct answer is: Portal vein and inferior vena cava

In the context of a surgical bypass procedure for portal hypertension, the correct choice involves the portal vein and the inferior vena cava. This procedure is typically employed to alleviate the elevated pressure in the portal venous system, which can occur due to various liver conditions. By creating a connection (bypass) between the portal vein and the inferior vena cava, blood flow is redirected away from the high-pressure portal system to the lower-pressure systemic circulation. This helps to reduce the pressure within the portal vein and can relieve complications associated with portal hypertension, such as variceal bleeding and ascites. The selective choice of the portal vein is significant, as it directly carries blood from the gastrointestinal tract and spleen to the liver. The inferior vena cava serves as a major conduit for returning deoxygenated blood to the heart. The strategic bypass facilitates improved blood flow dynamics, addressing the complications arising from high portal venous pressure. Understanding the anatomy and the physiological rationale behind this bypass is crucial for surgical management of portal hypertension, thereby highlighting the importance of this particular choice in the context of the procedure.
