Neoplastic invasion of the inferior vena cava due to renal tumors (especially Wilms' tumor) is uncommon in children. The tumor thrombus, according to the aggressiveness of the original neoplasm, can extend in diverse ways, obliterate the vascular lumen completely, and even reach the right atrium. The luminal thrombus might be accompanied by the involvement of the caval wall, which requires wide vascular resection. The purpose of this paper is to present our experience with 7 children, aged 18 months and 6 years, affected by caval invasion due to Wilms' tumor. Furthermore, the diagnostic techniques and the surgical treatment in simple caval thrombosis and in associated invasion of the caval wall are described.
肾肿瘤（尤其是肾母细胞瘤）导致的下腔静脉肿瘤性侵犯在儿童中并不常见。肿瘤血栓可根据原发肿瘤的侵袭性以不同方式延伸，完全阻塞血管腔，甚至可延伸至右心房。腔内血栓可能伴有腔静脉壁受累，这需要进行广泛的血管切除。本文旨在介绍我们对7例年龄在18个月至6岁之间、因肾母细胞瘤导致腔静脉侵犯的儿童的治疗经验。此外，还描述了单纯腔静脉血栓形成及合并腔静脉壁侵犯时的诊断技术和手术治疗方法。
