Intraoperative acute tumor lysis syndrome during laparoscopic splenectomy preceded by splenic artery embolization.

Laparoscopic resection has become the standard of care for routine splenectomy. Preoperative splenic artery embolization for massive splenomegaly has been described to allow a laparoscopic approach in previously ineligible laparoscopic candidates. Our case describes an intraoperative cardiac arrest secondary to tumor lysis after preoperative splenic artery embolization. The patient recovered fully after suffering acute renal failure requiring dialysis for 6 weeks postoperatively. Caution using this approach is necessary to avoid this rare and potentially lethal complication.
