Abstract

Microwave thermal tumor ablation is an expanding treatment option to obtain local control of focal liver tumors with complication rates similar to other thermal ablation techniques. We report two cases of portal vein segmental branch thrombosis identified by US and CT imaging 40 days following percutaneous microwave ablation. One patient was treated for hepatocellular carcinoma in a cirrhotic liver, the other was treated for metastatic colon cancer in an otherwise normal liver. Both patients were clinically asymptomatic when the thromboses were identified. Evaluation of the vascular anatomy surrounding the tumor and of risk factors for development of portal vein thrombosis is critical when selecting patients for microwave tumor ablation.

肝肿瘤微波消融后节段性门静脉血栓形成2例报告
微波肿瘤热消融是一种扩大的治疗选择,以获得局部控制局灶性肝脏肿瘤,其并发症发生率与其他热消融技术相似。我们报告两例门静脉节段性分支血栓形成经超声和CT检查后40天经皮微波消融。一名患者接受了肝硬化肝细胞癌的治疗,另一名患者接受了正常肝脏转移性结肠癌的治疗。当确定血栓形成时,两例患者均无临床症状。在选择微波肿瘤消融患者时,评估肿瘤周围血管解剖和门静脉血栓形成的危险因素是至关重要的。
