Patients and methods Over a 5-year period, 12 RAAs toms. In the group treated with GDCs there were no complications. Five of seven patients were clinically were treated by endovascular selective embolization. Four RAAs were occluded using NDCs and eight were improved, while two patients remained clinically unchanged. treated with GDCs. All coils were delivered through a microcatheter.

Intraparenchymal renal artery aneurysms. Case report with review and update of the literature

“…IRAAs may be detected incidentally as well as present with urologic symptoms and signs related to complications [2,3,7,30,31]. Flank or abdominal pain may be secondary to IRAA rupture with retroperitoneal hemorrhage as well as renal infarction.…”

“…In recent years, transcatheter arterial embolization has emerged as a simple, useful and effective technique in managing IRAAs [15,30,. Indications for using this procedure include IPRAA rupture, hematuria, renal infarction, small bleeding aneurysms in patients with arteritis, false aneurysms following renal biopsies or percutaneous procedures, and high risk patients for udergoing surgery.…”

Endovascular treatment of renal artery aneurysm—A case report

“…Endoluminal stentgrafting and detachable microcoil emboliation (packing) are the two main endovascular procedures. Both procedures have been reported on and in the short term are successful [1][2][3][4]. Superselective embolization of the aneurysm, which was originally used in treating intracranial aneurysms, is effective by occluding the sac while maintaining the patency of the feeding vessel.…”

Therapie der Nierenarterienstenosen

“…Selbst fusiforme Aneurysmen der Segment-arterien können autoplastisch rekonstruiert werden. Einige Autoren beschreiben die Ex-situ-Rekonstruktion von NAA bei 22-30% ihrer Patienten [13,17,31]. Als Indikationen für die Ex-situPräparation der Niere betrachten wir lediglich das rupturierte NAA mit großem retroperitonealen Hämatom sowie multiple, sehr peripher gelegene Aneurysmen der Segmentarterien mit der Notwendigkeit, Anastomosennähte jenseits der Parenchymgrenze ausführen zu müssen.…”
