Parallel Placement of Excluder Legs for the Treatment of a Type IIIb Endoleak Using AFX2.

Endoleak is a major complication of endovascular aneurysm repair (EVAR). Type IIIb endoleaks, which are caused by endograft fabric disruption, are relatively rare. Although relining of the previously placed endograft with another main endograft is considered an ideal approach, it is sometimes difficult.

F-FDG uptake as a predictive factor for progressive aortic enlargement in aortic dissection.

Objective: Progressive aortic enlargement (PAE) is a critical adverse event in patients with medically treated aortic dissection (AD). However, no reliable predictor of the PAE has been established. The purpose of this study was to evaluate the value of F-FDG PET/CT for the prediction of PAE in patients with medically treated AD.
