“…The endovascular approach has become popular, given its low invasiveness. It includes two main techniques: coil embolization and/or exclusion of the aneurysm by stent positioning [16]. Patients must be selected considering the anatomy of the vessels.…”

The renal artery aneurysms (RAAs) represent 3% of all visceral aneurysms. Their incidence rate is about 0.1% in the general population [1], even if angiographic findings report a little higher incidence (0.3-2.5%) [2] with a modest prevalence in female patients. RAAS are mainly detected in the sixthseventh decade, and female patients are associated with an earlier incidence [3]. True RAAs are extra-parenchymal in 90% of cases, while intraparenchymal RAAs represent 10% of cases, and they are often multiple and congenital. RAAs can be saccular in 75% of cases or fusiform. Saccular RAAs usually affect the main renal artery bifurcation, while fusiform aneurysms often involve the main arterial trunk [4]. RAAs can be bilateral (10-20%) or associated with a multiple location. High calcifications are detected in 18-68% of cases [1]. HRAAs represent a rare subgroup of RAAs, located in the distal part of the renal artery, very close to the renal hilum even though they are considered extra-parenchymal (Fig. 12.1). In addition to "true aneurysms," the main renal arteries and their collaterals can be affected by:

Renal arter anevrizması, renal arterin, dallarının veya her ikisinin de elastik dokularının ve arteriyel duvar yapısının zayıflaması nedeniyle lokal olarak genişlemesine denir. Poutasse sınıflamasına göre sakküler, fuziform, disseke ve intrarenal olmak üzere dört temel tipi vardır. Özellikle son yıllarda artan endovasküler tedavi tecrübesi ve teknoloji ile bağlantılı olarak, renal arter anevrizması tedavisinde endovasküler tedavinin öncelikli olduğunu belirten çalışmalarda da bir artış söz konusudur. Bu olgu sunumundaki amacımız endovasküler olarak tedavi edilen 3 cm'lik sol renal arter sakküler anevrizma rüptürlü hastayı sunmak ve literatür eşliğinde tartışmaktır.

“…An increasing number of patients are being treated by endovascular repair 6 9. Transcatheter embolisation, stent-assisted coiling and stent graft repair are the most commonly described methods 9–12. Compared with open surgery, endovascular repair is associated with a lower rate of postoperative complications and a shorter length of stay 13–15…”

Ex vivo repair and renal auto-transplantation for treatment of a renal artery aneurysm after endovascular failure

et al. 2019

View full text Add to dashboard Cite

Renal artery aneurysms are rare and typically found incidentally. Risk of rupture drives the incentive for repair, which can be achieved by both open and endovascular techniques. Ex vivo repair with renal auto-transplantation is recommended for complex aneurysms involving distal or multiple arteries. Here we describe a successful treatment of a renal artery aneurysm after previous endovascular treatment failure. A multi-layered stent was left misplaced inside of the aneurysm. Ex vivo repair with renal auto-transplantation allowed for complete aneurysm exclusion. With increasing use of endovascular techniques, failure of endovascular treatment might become a common indication for ex vivo repair in renal artery aneurysms.

Management of wide-based renal artery aneurysms using noncovered stent-assisted coil embolization

Abstract: SAE can be safely and effectively performed in patients with wide-based RAAs or those with critical anatomy. It showed a midterm reduction of blood pressure and improvement of renal function in RAA patients.
