Leiomyosarcoma (LMS) of inferior vena cava is a rare and aggressive tumor, arising from the smooth muscle cells in the vessel wall. A large complete surgical resection is the essential treatment. The need of vascular reconstruction is not always mandatory. It's above all to understand the place of the reconstruction with artificial vascular patch prosthetics of vena cave after a large resection of the tumor. We rapport two cases of LMS of inferior vena cava in two women who underwent successful large resection of tumor and lower segment of inferior vena cava. In first case, reconstruction of the inferior vena cava was not performed because of the development of venous collaterals derivation. In the second case reconstruction was done using Dacron interposition graft. The necessity of a large resection in management of primary leiomyosarcoma of vena cave makes sometimes unavoidable the sacrifice of a portion of the vena. Indeed, a better comprehension of the development of venous derivation may render unnecessary the reconstruction.
下腔静脉平滑肌肉瘤（LMS）是一种罕见且侵袭性强的肿瘤，起源于血管壁的平滑肌细胞。大型完整手术切除是关键治疗方法。血管重建并非总是必需的。最重要的是要了解在肿瘤大范围切除后，使用人工血管补片假体进行下腔静脉重建的情况。我们报告了两例下腔静脉LMS病例，两名女性患者均成功接受了肿瘤及下腔静脉下段的大范围切除。第一例中，由于静脉侧支循环的形成，未进行下腔静脉重建。第二例中，使用涤纶补片进行了重建。在原发性下腔静脉平滑肌肉瘤的治疗中，进行大范围切除有时不可避免地要牺牲一部分下腔静脉。事实上，更好地理解静脉侧支循环的形成可能使重建变得不必要。
