Abstract:
Objective To discuss the surgical therapy of primary leiomyosarcoma of the inferior vena cava(PIVCLS).Methods Retrospective analysis of was made 5 patients of PIVCLS from Oct 2009 to May 2011 hospitalized in Department of Vascular Surgery,Provincial Hospital Affiliated to Shandong University.All patients underwent surgical resection,combined with reconstruction of bilateral renal vein and distal inferior vena cava using artificial vascular graft.Results Surgical resection was performed successfully in all patients.The mean operation time was 166.6 min,with mean blood loss 1 560 mL.Leiomyosarcoma intruding the inferior vena cava and right renal vein were observed in all patients during operation.The mean size was 12 cm × 10 cm× 8 cm.The diagnosis of PIVCLS in 5 patients was confirmed by postoperative pathologic examination.All patients did not present lower extremity swelling after surgery and discharged from hospital with normal blood (BUN) and (CREA).All patients were administrated with oral warfarin therapy after discharge.No clinical relapse and pulmonary embolism was observed during the follow-up (range 3 months to 12 months).The ultrasound revealed the patency of artificial vascular grafts in all patients.Conclusions Surgical resection combined with reconstruction of bilateral renal vein and distal inferior vena cava using artificial vascular graft is an effective and feasible treatment of PIVCLS.Leiomyosarcoma is completely eliminated and important abdominal viscera are protected well during the procedure because of minimal impact on hemodynamics.The incidence of postoperative pulmonary embolism also decreases obviously.
