门脉高压症静脉曲张的CT诊断

CT DIAGNOSIS OF PORTAL HYPERTENSION AND VARICES

观察经临床证实30例门脉高压症的CT表现，包括食道静脉、食道周围静脉、小网膜静脉曲张，脐周静脉、脾静脉、奇静脉及半奇静脉扩张，以及肝硬化门脉高压症的其它伴随异常。CT在判定门脉高压和食道周围静脉、奇静脉、半奇静豚系统、小网膜及后腹膜是否存在静脉曲张和范围方面有肯定意义。同时对外科手术的选择有重要的指导意义。因此，CT是诊断门脉高压各侧支静脉曲张的重要方法。

CT findings of 20 patients wjth POrtal hyPertension and varices were reviewed, which include .eSOPhageal varices, paraeSOPhageal varice8, dilatation of aZygOS system, paraumbilical vein dilatation,dilated splenic vein, varices in the leber omentum and other abnormalities associated with portal hyPertension. CT is superior to barium esophagram in assessing the presence and extent of venous collaterals in patients with portal hyPertensfon. So CT is an important method to diagose esophageal varices.
