Magnetic resonance imaging (MRI) was performed in seven patients before and after portosystemic shunting to evaluate venous changes accompanying nonselective and selective shunt construction. The size and number of the intrahepatic portal and hepatic veins, left perirenal veins, and left upper quadrant varices were evaluated at MRI before and after shunt construction. MRI correctly diagnosed patent shunts in all seven patients. A marked decrease in the size of intrahepatic veins after a total or nonselective shunt suggests adequate portal vein and variceal decompression. Dilatation of left perirenal veins in the presence of a patent mesorenal or splenorenal shunt suggests hypertension of the left renal vein and possibly inadequate decompression of esophageal varices.
对7例患者在门体分流术前和术后进行了磁共振成像（MRI）检查，以评估非选择性和选择性分流术构建过程中伴随的静脉变化。在分流术构建前后通过MRI评估肝内门静脉和肝静脉、左肾周静脉以及左上象限静脉曲张的大小和数量。MRI正确诊断出所有7例患者的分流血管通畅。完全或非选择性分流术后肝内静脉大小显著减小提示门静脉和静脉曲张减压充分。在脾肾分流或脾肾分流血管通畅的情况下左肾周静脉扩张提示左肾静脉高压，可能食管静脉曲张减压不充分。
