Reconstruction of the renal artery after unsuccessful percutaneous transluminal angioplasty in children

Management of renal vascular disease in neurofibromatosis type 1 and the role of percutaneous transluminal angioplasty

“…It is generally felt that stenoses involving the renal ostium respond poorly to PTA. There have been mixed reports of the effectiveness of PTA in NF1 with success rates of approximately 30% [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Reasons cited for the poor outcome included position of the stenosis and the variable extent of fibrotic tissue involved [9].…”

Surgery after failed percutaneous renal artery angioplasty

“…Early surgical reports that describe significant perivascular inflammation and fibrosis after F-PTRA contrast with reports from the same time period that attribute minimal perivascular changes to F-PTRA. [6][7][8][9] Consequently, we have reviewed our experiences with secondary surgical intervention after F-PTRA in 51 patients (32 with atherosclerosis, 19 with fibromuscular dysplasia [FMD]) who underwent treatment at our institution during the past 11.5 years. Specific areas of interest included the influence of F-PTRA on the methods of secondary surgical repair, blood pressure and excretory renal function response to operation, and follow-up dialysis-free survival rates.…”

Percutaneous transluminal angioplasty of renal artery stenosis in a child with hypertensive heart disease

“…The best results have been obtained in fibromuscular dysplasia, short-segment stenosis, and in patients involving the middle or distal renal artery [10][11][12]. Children with bilateral RAS, neurofibromatosis, those involving the ostium of the renal arteries, and long-segment stenosis are usually refractory to PTA [11][12][13]. In addition, the experience of applicability of balloon angioplasty is limited in young children by the small vessel size.…”
