门静脉海绵样变的彩色多普勒声像图诊断

Color doppler sonographic diagnosis of cavernous transformation of portalvein

门静脉海绵样变病因属多因素性，ＣＴ检查诊断价值不大。对１９例门静海绵样变患者采用彩色多普勒进行检查，其中４例手术，３例同时术中门静脉属支置管造影，结果证实彩色多普勒检查诊断该病的可靠性。单用二维声像图检查易误为其它囊性病变。门静脉海绵样变导致门静脉高压和肝功能损害程度与向肝内侧支循环形成密切相关，单凭患者主诉和体格检查诊断有困难。

The results of the CDFI in l9 cases with cavernous transformation ofportal vein were repored.Among these 4,who were operate, portal venography wasperformed in 3 intraoperatively.Since 2-D ultrasonogram would easily to misdiagnosedfor multicystic lesion,the reliability of CDFI examination was confirmed byangiography and operation.Causes of the cavernous transformation of portal veinwere multiple.CT examination is seldom helpful.Since the portal hypertension andhepatocellular impairment caused by this disease is closely related to the centropetalcollateral circulation,it is difficult to establish the diagnosis only by relying on thepatient’s chief complaint and physical examination.
