Segmental arterial mediolysis is an unusual arterial lesion for which pathogenesis has remained controversial. We report on a 47-year-old Japanese woman who underwent surgery for an abdominal aortic aneurysm that was 10.5 cm in diameter and contiguous with a left common iliac aneurysm that was 2.3 cm in diameter; the aneurysms were considered to have progressed rapidly in size. Pathologic examinations of the respective aneurysms showed cystic medial necrosis in the aortic and segmental arterial mediolysis in the iliac aneurysm. Coexistence of these two pathologic findings indicates that there may be a strong relation between these two disease entities.
节段性动脉中层溶解是一种不常见的动脉病变，其发病机制一直存在争议。我们报告了一名47岁的日本女性，她接受了腹主动脉瘤手术，该动脉瘤直径为10.5厘米，与直径为2.3厘米的左髂总动脉瘤相连；这些动脉瘤被认为在大小上迅速进展。对各个动脉瘤的病理检查显示主动脉存在囊性中层坏死，髂动脉瘤存在节段性动脉中层溶解。这两种病理表现的共存表明这两种疾病实体之间可能存在密切关系。
