Abstract：Objective To evaluate the diagnostic value of multiple slice spiral CT portal venography ( CTPV) in the collateral circulation of liver cirrhosis with portal hypertension .Methods Tri-phase enhanced CT scan was performed in 109 patients with portal hypertension dut to cirrhosis .The diagnosis was proved by clinical data ,hepatic function findings and imaging signs .Three dimension imaging reconstruction of portal venous system and portal collat -eral circulation were obtained using posl-processing reconslruction technique .Results CTPV images displayed the portal venous system and its collateral circulation stereoscopically .Of 109 patients, left gastric varices were seen in 67(61.5%), lower esophageal varices in 87(80.0%), short gastric or posterior gastric varices in 10 (9.2%), par-aesophageal varices in 21(19.3%), gastro-renal or splenorenal shunts in 14(12.8%), spongelike transformation of portal vein in 18(16.5%), paraumbilical and abdominal wall varices in 15(13.8%), paravertebral venous shunts in 6(5.5%).Conclusion Multiple slice spiral CT can precisely display the location , extent and course of the col-lateral circulation .It can provide reliable imaging evidence for clinical evalution before treatment .
