Saccular renal artery aneurysm treated with an autologous vein-covered stent

Abstract

A 32-year-old woman underwent an autologous saphenous vein-covered stent deployment for the treatment of a saccular aneurysm on the distal renal artery. Complete exclusion of the aneurysm was immediately obtained. One year after the treatment, remarkable shrinkage of the aneurysm was demonstrated by means of computed tomography, and wide patency of the renal artery and the stent was shown by means of angiography.

Reconstruction for renal artery aneurysm: Operative techniques and long-term results

“…An unsatisfactory blood pressure control with severe late sequelae is a common consequence. Because operative treatment of RAA could be performed by experienced hands with a low morbidity and a mortality of zero in our series and in many other reported series, 20,[26][27][28][29] it should be recommended in patients with hypertension, offering a chance of healing or improving hypertension in about 50% to 100%. In patients with a short hypertensive history, the development of fixed renal hypertension may be avoided.…”

“…23,27,28,[31][32][33] Because of the small number of reported patients and the short follow-up periods, the durability of this alternative method cannot be assessed to date. Embolization or RAA as another endovascular technique has also been reported in single cases.…”

Treating coil migration in combination therapy involving stenting and coiling for a wide-necked renal aneurysm

“…There have been some reports in which a stent covered with a polytetrafluoroethylene membrane or vein was implanted to obstruct the ostium of the aneurysm [8,9]. In cases of aneurysm in which the ostium is in contact with the ostia of significant branches, the implantation of a covered stent should not be performed in order to ensure that they remain patent.…”

Covered stents: A review

“…Indications also include pain, hematuria, intrarenal distal embolization or evolution of renal failure [38]. Traditionally RAAs are treated by surgical repair or nephrectomy, although there are few reported cases of their percutaneous treatment [37][38][39][40][41][42]. In accordance with the classification of RAAs reported by Rundback et al [43], saccular aneurysms arising from the main branch with a small aneurysm neck (type 1) have to be treated percutaneously with the use of a covered stent.…”
