Twelve patients with portal vein thrombosis (PVT) associated with various disorders were examined. In 11 the diagnosis of PVT was made primarily by ultrasound. Endovenous lesions that presented with a mainly homogenous texture pattern of different echodensity could be clearly displayed, but failed to disclose specific echographic features that allow conclusive discrimination between blood clots (n = 7; mean diameter 13 +/- 1.7 mm) and venous tumor invasion (n = 5; mean diameter 24 +/- 12 mm). Thrombus resolution on therapy as well as cavernous transformation of the portal vein following acute PVT may be visualized by serial sonograms. Secondary findings in PVT that can be displayed by sonography include splenomegaly and superior mesenteric vein obstruction with intestinal ischemia. Real-time sonography has proved to be a valuable noninvasive method for the early diagnosis and follow-up of PVT.
对12例伴有各种病症的门静脉血栓形成（PVT）患者进行了检查。11例患者的PVT诊断主要通过超声做出。呈现出不同回声密度的主要均匀质地模式的静脉内病变能够清晰显示，但未能揭示可对血栓（n = 7；平均直径13±1.7毫米）和静脉肿瘤侵犯（n = 5；平均直径24±12毫米）进行明确鉴别的特定超声特征。治疗后血栓溶解以及急性PVT后门静脉的海绵样变可通过系列超声检查图显示。超声检查可显示的PVT继发性表现包括脾肿大和肠系膜上静脉梗阻伴肠缺血。实时超声检查已被证明是PVT早期诊断和随访的一种有价值的非侵入性方法。
