“…A pathological classification of renal artery FMD was proposed by McCormack et al [3][4] It was based on the dominant arterial wall layer involved: the intima, media or adventitia. Intimal FMD, which accounts for 5 % of renal artery FMD cases, is characterized by irregularly arranged mesenchymal cells within a loose matrix of subendothelial connective tissue and a fragmented internal elastic lamina.…”

“…Such pathologic changes are demonstrated by a "string-of-beads" appearance via angiography. [4][5][6] The "string-of-beads" appearance, which angiographically characterized medial FMD, occurs in about 70 % of cases. Specific features of adventitial or intimal FMD cannot be shown using angiography.…”

“…Specific features of adventitial or intimal FMD cannot be shown using angiography. [4][5][6][7] Focal or tubular angiographic aspects cannot be related to specific histological lesions. In cases with focal and tubular FMD stenosis, differential diagnoses are atherosclerotic or inflammatory arterial disease, vascular Ehlers-Danlos and Williams' syndromes, and type 1 neurofibromatosis, etc.…”

“…The medial fibroplasia is a major type of FMD, and 60%-70% of this type show "string-of-beads" appearance via angiography. [4][5][6][7] IVUS was useful in differentiation of FMD from atherosclerosis in such a focal stenosis type via angiography. Furthermore, IVUS images were useful in not only the evaluation of both the lesion diameter and lesion form, but also decision making of both balloon size and end point of strategy.…”

“…The present study is the first in which coarctation as a cause of RAS was evidenced clinically. It is noteworthy that 32 years ago, McCormack et al 10 Renal arteries are divided into the adaptive remodeling and coarctation groups according to the relative MBA at the target site (Ͼ85% and Յ85%, respectively). Values are meanϮSD and represent the averaged results of the 2 independent observers.…”

Intravascular Ultrasound Evidence for Coarctation Causing Symptomatic Renal Artery Stenosis

Background-A recent study of human cadaveric renal arteries revealed that renal artery narrowing could be due not only to atherosclerotic plaque compensated for by adaptive remodeling, but also to hitherto undescribed focal narrowing of an otherwise normal renal arterial wall (ie, coarctation). The present study investigated whether vessel coarctation could be identified in patients with symptomatic renal artery stenosis (RAS). Methods and Results-Consecutive symptomatic patients with angiographically proven atherosclerotic RAS who were referred for stent placement were studied by 30-MHz intravascular ultrasound before intervention (nϭ18) or after predilatation (nϭ18). Analysis included assessment of the media-bounded area and plaque area (PLA) at the most stenotic site and at a distal reference site (most distal cross-section in the main renal artery with normal appearance).Coarctation was considered present whenever the target/reference media-bounded area was Յ85%. Before intervention, coarctation was observed in 9 of 18 patients and adaptive remodeling in 9 of 18 patients. Coarctation lesions had a significantly smaller PLA than adaptive remodeled lesions (Pϭ0.001). Similarly, despite predilatation, coarctation was seen in 8 of 18 patients who had significantly smaller PLAs (Pϭ0.008) when compared with those patients who had adaptive remodeled lesions. No differences in severity of RAS or angiographic or clinical parameters were observed. Conclusions-Low-plaque coarctation may cause a considerable proportion of symptomatic RAS, which is angiographically and clinically indistinguishable from plaque-rich RAS.
