Investigation on diagnosis of cirrhotic portal hypertension and compensatory circulation by trans-splenic portal scintigraphy with ~(99m)Tc-Phytate / 中国现代普通外科进展

ABSTRACT

Objective: To investigate the diagnostic value and clinical significance of trans-splenic portal scintigraphy in cirrhotic portal hypertension and compensatory circulation. Methods: Transsplenic portal scintigraphy, ultrasound, and gastroscopy were performed on 50 patients with cirrhotic portal hypertension and on 10 controls. According to the Child-Pugh classification, 15 patients with cirrhosis were Child A, 19 cases were Child B, and 16 cases were Child C. Results: In the control group, the splenoportal vein was shaped like the letter S, and the portosystemic shunt index was 0.19?0.07. Portal hypertension portosystemic shunts were of 3 types intrahepatic (13 patients; index, 0.52?0.19), compensatory(31 patients; index, 0.64?0.28)and completely extrahepatic (6 patients; index, 0.91?0.03). Collateral vessels were uphill, downhill, or complex. The portosystemic shunt index increased as cirrhosis and esophageal varices increased. There was statistical significance among groups(P
