Unusual Case - Massive intestinal infarction following retroperitoneoscopic right lumbar sympathectomy Rulli Francesco, Galata Gabriele, Micossi Chiara, Dell'Isola Carlo Abstract The adverse physiological effects of pneumo and retro-peritoneum are relatively well known. However, the clinical implications of compromised mesenteric circulation through several mechanical and physiological mechanisms are not as well recognized. We describe a fatal case of intestinal infarction following an elective retroperitoneoscopic right sympathectomy. The patient was a 88-year-old man who died 30 hours after an uneventful anesthesia and right endoscopic lumbar sympathectomy. An emergency explorative laparotomy revealed a massive intestinal infarction due to thrombosis of the superior mesenteric artery. We reviewed the literature on laparoscopic procedures and mesenteric ischemia. To our knowledge, this is the first reported case of intestinal infarction following retro-pneumoperitoneum. We conclude that the presence of a severe multidistrectual? arteriopathy may represent a major risk factor in retroperitoneoscopic procedures.
