A 55 year old male patient presents with chronic liver disease has poal hypeension. To relieve the pressure in the poal system, a poocaval shunt is performed. Which of the following veins may be anastomosed to accomplish this poacaval shunt?
The splenic vein drains directly into the poal vein. The left renal vein drains directly into the inferior vena cava. Anastomosis of these veins would allow blood from the poal vein to drain retrograde through the splenic vein into the renal vein and then into the inferior vena cava.The left renal vein drains directly into the inferior vena cava. The left testicular vein drains directly into the left renal vein. Thus, these veins are already in communication and neither vein is pa of the poal venous system.The right renal vein drains directly into the inferior vena cava. The right suprarenal vein also drains directly into the inferior vena cava. Thus, neither vein is pa of the poal venous system.The superior mesenteric vein drains directly into the poal vein. The inferior mesenteric vein drains into the splenic vein, which then drains into the poal vein. Thus, neither vein is pa of the caval venous system. Ref: Geller D.A., Goss J.A., Tsung A. (2010).

Left renal vein-left testicular vein
Right renal vein-right suprarenal vein
Splenic vein-left renal vein
Superior mesenteric vein-inferior mesenteric vein
