Anaesthesia for autotransplantation after extracorporeal nephron sparing surgery for bilateral giant renal angiomyolipoma

Abstract

Extracorporeal ‘work bench surgery’ with subsequent autotransplantation is a challenge from both anaesthetic and surgical point of view when performed bilaterally or in a solitary kidney. A 28-year-old female with bilateral giant angiomyolipoma of kidneys was taken up for renal autotransplantation. Patient had a huge tumour, which was the largest reported exophytic tumour to be excised by this technique. Both kidneys were operated at an interval of 1 month, under combined general and epidural anaesthesia. Anaesthetic challenges faced during the procedure were maintenance of adequate perfusion of the grafted kidneys, containment of massive blood loss and coagulopathy during the perioperative period. Patient recovered in due course with functioning autotransplanted kidney. A careful pre-operative preparation with intraoperative maintenance of adequate blood volume and blood pressure is the key for graft survival.
