Pseudoaneurysms are caused by trauma, tumors, infections, vasculitis, atherosclerosis and iatrogenic complications. In this paper, we report about a patient with rupture of an external iliac artery pseudoaneurysm, which lead to hemorrhagic shock, after undergoing laparoscopic radical cystectomy and extended pelvic lymphadenectomy.
The patient was a 68-year-old Japanese male diagnosed with invasive bladder cancer. Laparoscopic radical cystectomy and extended pelvic lymphadenectomy were performed. On postoperative day 12, he developed a high fever and an acute inflammatory response with redness and swelling in the right inguinal region. He was diagnosed with necrotizing fasciitis and underwent debridement. On postoperative day 42, a sudden hemorrhage developed from the open wound in the right inguinal region. He was diagnosed with external iliac artery pseudoaneurysm rupture by computed tomography.
These complications occur extremely rarely after cystectomy with pelvic lymphadenectomy. There are no reports to date on these complications following laparoscopic cystectomy with pelvic lymphadenectomy.
假性动脉瘤由创伤、肿瘤、感染、血管炎、动脉粥样硬化和医源性并发症引起。在本文中，我们报告了一例患者，其在接受腹腔镜根治性膀胱切除术和扩大盆腔淋巴结清扫术后，髂外动脉假性动脉瘤破裂，导致失血性休克。
该患者为一名68岁的日本男性，被诊断为浸润性膀胱癌。实施了腹腔镜根治性膀胱切除术和扩大盆腔淋巴结清扫术。术后第12天，他出现高热及急性炎症反应，右侧腹股沟区红肿。他被诊断为坏死性筋膜炎并接受了清创术。术后第42天，右侧腹股沟区的开放伤口突然出血。通过计算机断层扫描，他被诊断为髂外动脉假性动脉瘤破裂。
这些并发症在膀胱切除术加盆腔淋巴结清扫术后极为罕见。迄今为止，尚无关于腹腔镜膀胱切除术加盆腔淋巴结清扫术后出现这些并发症的报道。
