肾脏、肾上腺及肝脏肿瘤所造成的下腔静脉肿瘤性栓塞是众所周知的并发症,但由于腹膜后生殖细胞瘤侵犯下腔静脉而形成肿瘤性栓塞至今尚未见报道,作者分析了3例,男性2例,女性1例。CT图象上可见下腔静脉及肾静脉腔内充盈缺损及其附近肿块阴影。第1例病人是由于生殖细胞肿瘤侵蚀肾静脉壁,进入肾静脉,然后进一步蔓延进入下腔静脉引起栓塞;另2例是由于肿瘤直接侵及下腔静脉并在腔内生长形成瘤栓。有时巨大肿瘤压迫下腔静脉,使血流减慢,亦可造成血栓形成。在临床上如能诊断出腹膜后恶性肿瘤是下腔静脉腔栓塞形成的原因,可避免采用一般的溶血栓疗法而耽搁疗
Renal, adrenal and liver tumors caused by the tumor of the inferior vena cava tumor embolization is a well-known complication, but because of retroperitoneal germ cell tumor invasion of the inferior vena cava tumor embolism has not been reported, the authors analyzed in 3 cases, male 2 Cases, female 1 cases. CT image shows the inferior vena cava and renal venous filling defects and the shadow of the mass near the cavity. The first patient is due to germ cell tumors erode the renal vein wall, into the renal vein, and then further spread into the inferior vena cava causing embolism; the other two cases because the tumor directly invaded the inferior vena cava and tumor growth in the cavity tumor emboli. Sometimes huge tumor oppresses the inferior vena cava, slowing the blood flow, can also cause thrombosis. If clinically diagnosed with retroperitoneal malignancy is the cause of inferior vena caval embolism can avoid the use of general thrombolytic therapy delay treatment
