Abstract:
We present the case of delayed migration of a thrombosed aortic endograft within a thrombosed aneurysm sac that expanded and ruptured. Dilation of the aortic neck likely led to endograft migration and exposure of the occluded endograft and aneurysm sac to systemic pressure. Although no endoleak was identified, a key finding on ultrasound showed mobility of the sac thrombus. This may be an indicator of flow within the sac that may predict potential for rupture. Despite thrombosis of the aortic sac and endograft, the risk of rupture still lingers, and thus continued surveillance of occluded endografts may be prudent.
