The rupture risk of abdominal aortic aneurysms (AAAs) depends primarily on their diameter and increases exponentially with aneurysm growth. Therefore, giant AAAs, defined as > 13.0 cm in diameter, are rare clinical entities.
A giant ruptured AAA that measured >20 cm in diameter was successfully treated by open repair.
It remains unclear why giant AAAs continue to grow to extreme size without rupturing. Open repair seems to be the treatment of choice for most giant aneurysms, both ruptured and unruptured.
腹主动脉瘤(AAA)的破裂风险主要取决于其直径,并随动脉瘤的生长呈指数级增加。因此,直径大于13.0厘米的巨大AAA是罕见的临床病例。
一例直径大于20厘米的巨大破裂性AAA通过开放修复成功治疗。
目前尚不清楚为什么巨大AAA会持续生长到极大尺寸而不破裂。对于大多数巨大动脉瘤,无论是破裂的还是未破裂的,开放修复似乎都是首选的治疗方法。
