A Physician Made Biological Stent Graft for the Replacement of a Left Renal Vein Leiomyosarcoma

Year: 2025

Type: article

Abstract: Introduction: Primary venous leiomyosarcoma is an unusual and aggressive tumour; its presentation on the renal vein is rare. This case study presents a 50 year old man with severe obesity who was incidentally diagnosed with a left renal vein leiomyosarcoma during pre-operative evaluations for a cholecystectomy. Following a multidisciplinary discussion with oncology and vascular surgeons, the patient underwent complete resection of the left renal vein along with the mass. Technique: resection of the leiomyosarcoma are shown, followed by reconstruction of the vein using a nitinol stent covered with bovine pericardium. Several precautions were adopted to minimise the risk of intestinal fistula, including heterotopic graft re-implantation and omentoplasty. Discussion: resection of renal vein sarcomas with nephrectomy. This case report presents an innovative surgical technique for left renal vein replacement, showing a potential alternative in the management of this rare condition in order to preserve the vein.
