Abstract:
Objective CT angiography (CTA) of the portal vein system by 16 detector spiral CT was performed to determine etiopathogenisis, collateral and gastro-renal shunt in the patients with portal hypertension. MethodsThirty-two patients suspected of portal hypertension were examined and reconstructed by arterial-venous double-phase scan. Results Twenty-seven patients with portal hypertension were revealed by CT scan and reconstruction, with spleen vein thrombosis in 4 cases, congenital cavernous transformation of portal vein in 3 cases, gastro-renal shunt in 9 cases, and simply liver cirrhosis and portal hypertension in 11 cases. Conclusion Portal CTA is a significantly important and useful examination method for portal hypertension patients, it could help to determine not only the range, degree and variation of esophageal and gastric varices, but also the etiopathogenisis of non-cirrhotic portal hypertension.
