We report the anatomical similarity of abdominal aortic aneurysms (AAAs) regarding morphology and visceral vessel relations with three-dimensional computed tomography in monozygotic twins, both of whom had the left accessory renal artery, patent inferior mesenteric artery and bilateral common iliac artery aneurysms without aortic wall calcification and mural thrombus in the same fashion. Both twins underwent AAA open repair for enlargement of it at the same age. Genetic contributions might be strongly associated with morphology and visceral vessel relations of AAAs in monozygotic twins.
我们报告了同卵双胞胎腹主动脉瘤(AAA)在形态学和内脏血管关系方面与三维计算机断层扫描的解剖学相似性,两人均有左副肾动脉、肠系膜下动脉通畅以及双侧髂总动脉瘤,且主动脉壁无钙化和壁内血栓,情况相同。双胞胎在同一年龄因AAA扩大均接受了开放修复手术。遗传因素可能与同卵双胞胎AAA的形态学和内脏血管关系密切相关。
