巨大的腹主动脉瘤

图示:动脉分支的上方有个大动脉粥样硬化形成的动脉瘤。当这种动脉瘤达到6-7cm时就很容易破裂。体格检查可在腹部查到搏动的肿块。大多这样的动脉瘤位于肾动脉下面附近,这就使得临床外科手术切除得以更好的执行,原因是在此处可以有效进行人工修补。

Here is an example of an atherosclerotic aneurysm of the aorta in which a large "bulge" appears just above the aortic bifurcation.Such aneurysms are prone to rupture when they reach about 6 to 7 cm in size. They may be felt on physical examination as a pulsatile mass in the abdomen.Most such aneurysms are conveniently located below the renal arteries so that surgical resection can be performed with placement of a dacron graft.
