Retroperitoneal leiomyosarcomas account for <1% of all tumors diagnosed in the U.S. They are usually unresectable at the time of diagnosis due to their vague clinical presentation. Aortic rupture from tumor invasion by retroperitoneal leiomyosarcomas is extremely rare and has only been described in one case report. We describe a case of an unresectable retroperitoneal leiomyosarcoma eroding into the infrarenal abdominal aorta resulting in an acute contained intratumoral hemorrhage successfully treated with a percutaneous placed abdominal aortic endograft. This article discusses the endovascular treatment of this rare medical emergency performed quickly and effectively in our endovascular suite. Endovascular specialists should be familiar with this lifesaving endovascular option in the setting of an acute aortic rupture.
腹膜后平滑肌肉瘤占美国所有确诊肿瘤的比例不到1%。由于其临床表现模糊，通常在诊断时无法切除。腹膜后平滑肌肉瘤侵袭导致主动脉破裂极为罕见，仅有一篇病例报告对此进行过描述。我们报告一例无法切除的腹膜后平滑肌肉瘤侵蚀肾下腹主动脉，导致急性肿瘤内局限性出血，经皮置入腹主动脉内支架成功治疗的病例。本文讨论了在我们的血管腔内治疗室快速有效地对这种罕见医疗急症进行血管腔内治疗的情况。血管腔内治疗专家应熟悉在急性主动脉破裂情况下这种挽救生命的血管腔内治疗方法。
