We report the sudden unexpected death from exsanguination of a 60-year-old white female who underwent balloon angioplasty of her right popliteal artery via a right common femoral arteriotomy 3 weeks before death. This resulted in a mycotic pseudoaneurysm of the right femoral artery that ruptured, causing fatal exsanguination. A pseudoaneurysm is an arterial wall defect in which part of the wall consists of fibrin and fibrous tissue, lacking components of the normal arterial wall, that is intima, media, and adventitia. Pseudoaneurysms result from traumatic arterial injury, infection, rupture of a true aneurysm, or surgery. A literature search revealed no reports with the patient dying unexpectedly outside the hospital. Immediate surgical intervention and antibiotic therapy are preferred treatments.

我们报告了一名60岁白人女性因放血而突然猝死的原因，该女性在死亡前3周通过右股总动脉切开术对其右pop动脉进行了球囊血管成形术。这导致右股动脉的真菌性假性动脉瘤破裂，导致致命的放血。假性动脉瘤是动脉壁缺损，其中部分壁由纤维蛋白和纤维组织组成，缺乏正常动脉壁的成分，即内膜，中层和外膜。假性动脉瘤是由外伤性动脉损伤，感染，真正的动脉瘤破裂或手术引起的。文献搜索显示，没有报告称患者在医院外意外死亡。立即手术干预和抗生素治疗是首选治疗方法。
