Retroperitoneal hematomas are a rare and fatal complication of endovascular embolization. We report a case of an 89-year-old woman who was referred to interventional radiology for percutaneous embolization for intractable epistaxis as a result of a left nasal cavity mucosal melanoma. After successful embolization of the left sphenopalatine artery, the patient became hypotensive and was transferred to the intensive care unit. Post-operative CT abdomen and pelvis angiogram showed a large right perinephric hematoma, which is an extremely uncommon complication of endovascular embolization for epistaxis. Practitioners should be aware of this life-threatening complication in weighing the risks and benefits of embolization versus direct surgical ligation, and they should identify and intervene promptly if a retroperitoneal hematoma should occur.
腹膜后血肿是血管内栓塞术罕见且致命的并发症。我们报告一例89岁女性，因左鼻腔黏膜黑色素瘤导致顽固性鼻出血，被转诊至介入放射科行经皮栓塞治疗。成功栓塞左蝶腭动脉后，患者出现低血压并被转入重症监护病房。术后腹部和盆腔CT血管造影显示右侧肾周巨大血肿，这是鼻出血血管内栓塞术极为罕见的并发症。在权衡栓塞与直接手术结扎的风险和益处时，从业者应意识到这种危及生命的并发症，并且如果发生腹膜后血肿，应及时识别并进行干预。
