Nonthrombotic pulmonary embolism is an uncommon life-threatening complication following liposuction. We report a rare incidental autopsy finding associated with this procedure. A 43-year-old female who underwent liposuction presented with hypotension, respiratory distress, loss of consciousness and cardiorespiratory arrest during the intraoperative period. The patient died 2 h after admission to the emergency department. Autopsy reported a massive hemoperitoneum (2.2 L) secondary to liver perforation associated with liposuction as the cause of death. Pelvic, umbilical and lumbar peritoneal perforations were also observed. The histological study showed segments of the pulmonary arteries occluded by mixed emboli of skeletal muscle fibers coexisting with fatty tissue. We discuss the origin, pathophysiology and clinical manifestations of this new kind of mixed pulmonary embolism.

非血栓性肺栓塞是抽脂术后罕见的危及生命的并发症。我们报告了与此程序相关的罕见的偶然尸检发现。一名 43 岁女性接受吸脂术，术中出现低血压、呼吸窘迫、意识丧失和心肺骤停。患者入急诊后 2 h 死亡。尸检报告称，继发于与吸脂相关的肝穿孔的大量腹腔积血 (2.2 L) 是死亡原因。还观察到骨盆、脐带和腰椎腹膜穿孔。组织学研究显示肺动脉部分被与脂肪组织共存的骨骼肌纤维混合栓塞阻塞。我们讨论起源，
