Abstract:
The aim of this study is to describe renal artery entrapment (RAE) by the diaphragmatic crus and to elucidate the diagnostic and therapeutic approach to this entity. From 1995 to 2002, 15 patients (mean age 65) were found to have a RAE. They were investigated by CT scan (n=14) and/or MRA (n=2) for hypertension (n=7), chronic renal insufficiency (n=4) or aneurysms (n=4). The right (n=11) or the left (n=4) renal artery (RA) was involved. The compression was ostial (n=8) or truncal (n=7), and was > or = 50% in eight cases. The course of the RA along the aorta on angiographic views (n=8) or a concentric ostial stenosis in a patient free of atheromatous lesions (n=7) were two findings suggestive of an RAE. Seven RAEs were indicated for treatment but only three were treated, by mean of stenting. Among the latter, two stents were patent at 6-month follow-up and one evolved to restenosis because of a stent fracture. RAEs may be suspected on angiographic views and proved by cross-sectional imaging because of specific imaging features. It is of importance to detect this etiology of RA stenosis because angioplasty with stenting is probably not always advisable.
