摘要(Abstract):

本文报道20例门静脉栓塞形成的病因及声像图特征。本组病因以原发性肝癌引起的癌栓形成最为多见(占90%)。声像图的特征为:①在门静脉内可见条索状或散在团块状光团,其回声强度大多与肝实质回声相似;②光团边缘多数较清晰;③栓塞所在部位的门静脉可有不同程度的扩张;④光团后部回声无衰减;⑤栓塞部位近端的门静脉内径可增宽。
Portal vein thromboses diagnosed by sonography in 20 patients are report- ed,in whom the commonest cause was due to venous invasion by primary he- patic carcinoma(90%). Sonographic features of portal vein thrombosis are as follows: 1.The lumen of the portal vein is filled with an echogenic thrombus.Its echogenicity is similar to the parenchyma in most cases.2.The outline of the echogenic thro- rebus is clear-cut in 13/20 cases.It is obscure in 7 cases being distingushed from the surrounding liver parenchyma only by the hyperechoic wall of the portal vein.3.The thrombosed vein is dilated in 12/17 cases(from 18 to 27 mm). 4.There is no attenuation or enhancement behind the thrombosed portion of the vein.5.The diameter of the portal vein in the proximity of the thrombus is increased in 14/17 cases(82.4%).
