Fenestrated endografts extend the treatment options for infrarenal AAAs with necks unsuitable for standard endovascular repair. This early data show a trend toward higher mortality of selected patients with fenestrated endografts than for standard stent-graft repair, but the mortality rate is comparable to open repair. Target vessel occlusion predominantly results from pre-existing disease or the lack of a stent. The lessons learned from this experience contributed toward guidelines for users of fenestrated endografts.

Background

Our preliminary study shows that VIE proved superior to conventional 2D or MPR images in visualizing the final configuration of the fenestrated vessels and was comparable to the other techniques in measuring stent protrusion into the aortic lumen. VIE could be a valuable technique to identify any suspected abnormalities associated with fenestrated endovascular grafts by demonstrating the final intraluminal configuration of the stents in the fenestrated vessels.

Cystic adventitial disease (CAD) is a rare non-atherosclerotic cause of peripheral vascular disease (PVD). We describe a 54-year-old man who presented with calf claudication and catheter angiography showed the typical scallop appearances of CAD. Surgery involved resection of the diseased segment with a femoral popliteal venous bypass graft. A literature review revealed the different theories for pathogenesis, the investigation of choice being catheter angiography and the treatment excision with bypass grafting.
