目的探讨超声在检测肝癌所致门静脉、肝静脉、下腔静脉内癌栓的应用价值。方法回顾分析24例门静脉、肝静脉及下腔静脉的1支或多支内的肝癌癌栓的声像图变化特点,并追踪其生存期。结果肝癌侵犯血管以侵犯门静脉分支形成癌栓最常见,肝静脉癌栓病检常见但超声检查却发现较少,而下腔静脉癌栓超声检查发现更少。所有24例患者经治疗后直到患者死亡之前所做的超声追踪检查中未见静脉内癌栓有明显减少或闭塞再通者。结论肝癌并发静脉内癌栓者其预后很差,而无静脉内癌栓者其预后相对较好;超声探查肝癌有无静脉内癌栓形成及其对血液回流的影响程度,可为临床选择治疗方案和判断预后提供重要依据。
Objective To investigate the value of ultrasound in the detection of portal vein, hepatic vein and inferior vena cava tumor thrombus caused by liver cancer. Methods A retrospective analysis of 24 cases of portal vein, hepatic vein and inferior vena cava in one or more of the characteristics of hepatocellular carcinoma thrombus changes in the characteristics and follow-up of its survival. Results Hepatocarcinoma invaded blood vessels to invade the branches of portal vein to form thrombus. The common hepatic vein thrombosis is common, but ultrasound examination is less, but the inferior vena cava tumor thrombus ultrasound examination found less. All 24 patients after treatment until the patient died before the ultrasound follow-up examination did not see a significant reduction in venous thrombosis or occlusion recanalization. Conclusions The prognosis of patients with hepatocellular carcinoma complicated with thrombus in the thoracic vein is very poor, and the prognosis is better with no thrombus in the thoracic cavity. The presence of venous thrombus and their influence on the return of blood flow can be explored by ultrasound Program and determine the prognosis provide an important basis.
