Abstract:
:A type II endoleak (T2EL) is the most common endoleak after endovascular aneurysm repair (EVAR), and a persistent T2EL has been occasionally associated with aneurysmal enlargement. Typical findings of a T2EL consist of an endoleak cavity with inflow and outflow arteries of aortic branch vessels. However, an atypical T2EL, in which hypertrophied vasa vasorum and enlargement of a thrombosed aneurysm are observed, has no endoleak cavity. We have seen three cases of continuous aortic aneurysmal growth after EVAR caused by atypical T2ELs without endoleak cavities through developed vasa vasorum. In this report, the imaging findings of selective angiography and dynamic computed tomography of these cases are reviewed.

杂志文章abstract::An aneurysm of the right renal artery was discovered in a patient suffering from cerebral arterial angiodysplasia and arterial hypertension. The aneurysm was large necked, which made selective endovascular treatment very difficult. To perform the embolization of the aneurysm, a balloon remodelling technique was used. ...
