Endovascular Exclusion of Renal Artery Aneurysm

Abstract

A patient who was operated for an abdominal aortic aneurysm 7 years earlier presented with recently discovered iliac and renal artery aneurysms. The renal artery had an angulation of 90 , but the aneurysm was successfully excluded using a covered vascular stent graft placed over an extra stiff guidewire. Even in cases of complex anatomy of a renal aneurysm, endovascular treatment should be considered. With development of more flexible and low-profile endoprosthesis with accurate deployment, these have become more usable.

Nonoperative management of unruptured visceral artery aneurysms: Treatment by transcatheter coil embolization

“…The reports on renal artery aneurysm exclusion with stent grafts are limited so far. 20 With the development of more flexible and low profile endoprosthesis with accurate deployment, these stent grafts will become more usable, even in complex lesions.…”

Concomitant Renal Artery and Aortic Aneurysm: Is Endovascular Surgery the Correct Approach?

“…It has been more frequently observed in the paediatric population 3 while between adults only anecdotal cases have been reported with a particular localization at the origin of the renal artery. 5,6,7 (Tab. While the approach to RAA is not universally shared, because its treatment is strictly dependent on location and anatomical features, being controversial and technically challenging the endovascular repair of AAAs is widely described and considered feasible even in complex anatomies thanks to the development of advanced endovascular procedure such as parallel grafts.…”

“…voce Even much rare is the association of RAA with an abdominal aortic aneurysm (AAA) and literature provides only few anedoctal examples. 3,4,54,5,6,6 Owing to their the rare finding it is still debated which could beis the best approach to treat both the aneurysms, if at once or in multiple steps.…”

Emergent coil embolization for ruptured renal artery aneurysm

“…7 Endovascular treatments include transcatheter embolization and stent grafting. [1][2][3]11,12,[14][15][16][17][18][19] Transcatheter arterial embolization using stainless steel coils or platinum microcoils has been the most frequently employed endovascular treatment for ruptured RAA, as summarized in Table 1. 11,[14][15][16][17][18][19] In the cases reported by Naitoh et al 18 and Take et al 19 , embolization was fi rst performed followed by nephrectomy after the patient's general condition had improved.…”

“…1 Patients with RAA are often asymptomatic, but it can be lifethreatening when rupture (although rare) occurs. [2][3][4] We report a case of ruptured renal artery aneurysm successfully treated by emergent transcatheter embolization with microcoils.…”
