Final answer:
The connection between the left splenic vein and the left renal vein is defined as a splenorenal shunt (c), which facilitates the rerouting of blood to alleviate portal hypertension by connecting directly to the systemic venous circulation.
Step-by-step explanation:
The correct answer to the question regarding the shunt between the left splenic vein and the left renal vein is c) splenorenal shunt. This type of shunt enables blood to be rerouted in cases where the hepatic portal vein is blocked or constricted, leading to portal hypertension. The splenorenal shunt connects the splenic vein to the left renal vein, allowing blood from the spleen to bypass the liver and flow directly into the systemic circulation through the left kidney's systemic venous outflow.
In patients with liver disease or portal hypertension, these collaterals and shunts can become enlarged, forming varices as a compensatory mechanism to relieve the pressure within the portal system. The presence of a splenorenal shunt is significant in clinical scenarios such as liver disease and may be considered for therapeutic interventions. This is due to the fact that the hepatic portal system is responsible for processing materials from the digestive and circulatory organs to the liver, and collaterals like the splenorenal shunt can impact systemic and hepatic circulations.
