[Right primary iliac artery rupture during transurethral resection of bladder tumor]

Injury to a large-caliber artery transurethral resection of a bladder tumor is a rare but serious complication. It is important that an anesthesiologist be able to detect such an injury, in order to include it among the many differential etiological diagnoses for shock. A 75-years-old man reported hematuria. An ultrasound image of the bladder showed many neoformations consistent with a diagnosis of multiple bladder neoplasms, and transurethral endoscopy was performed under subarachnoid anesthesia. Acute hypotension, bradycardia and shock developed 30 minutes into the procedure. The diagnosis was hypovolemic shock due to acute intraoperative hemorrhage, and exploratory laparotomy revealed an opening in the common iliac artery. The rupture was sutured. In spite of administration of crystalloids, colloids, blood products and vasoactive agents, a second operation was required due to hemodynamic instability. The patient died in the intensive care unit.
