Endovascular stent graft repair with chimney technique of an abdominal aortic aneurysm with concomitant horseshoe kidney

Abstract

ÖZAltmış sekiz yaşında erkek hasta infrarenal abdominal aort anevrizmasının tedavisi için kliniğimize sevk edildi. Bilgisayarlı tomografi anjiyografide anevrizmanın üstünde at nalı böbreği izlendi. Hastada anevrizmanın ön tarafından çıkan aksesuar renal arter mevcut idi. Endovasküler anevrizma tamiri yapıldı ve aksesuar renal arter baca tekniği ile morbidite olmadan başarılı bir şekilde revaskülarize edildi. Ameliyat sonrası bilgisayarlı tomografi anjiyografide, kaçak olmaksızın ve baca greft açıklığı ile anevrizmanın tamamen ekarte edildiği görüldü.Anah tar söz cük ler: Aksesuar renal arter, baca tekniği, endovasküler anevrizma tamiri, fenestrasyon, şnorkel. ABSTRACTA 68-year-old male patient was referred to our clinic for treatment of an infrarenal abdominal aortic aneurysm. Computed tomography angiography revealed a horseshoe kidney overlying the aneurysm. The patient had an accessory renal artery arising from the anterior aspect of the aneurysm. Endovascular aneurysm repair was performed and the accessory renal artery could be revascularized successfully by chimney technique without any morbidity. Postoperative computed tomography angiography revealed complete exclusion of the aneurysm with no endoleak and a patent chimney graft.

Impact of Accessory Renal Artery Embolization on Renal Deterioration Under Endovascular Aortic Repair

“…If there is a risk of postoperative renal deterioration, additional preservation procedures for aRA, such as chimney procedure, fenestration, branched procedure, and open abdominal repair should be considered. [17][18][19] In our experience, we treated a patient with abdominal aortic aneurysm along with one congenital kidney and one aRA. The patient's preoperative renal volume was 93 mL and preoperative eGFR was 34.8 mL/min/1.73 m 2 .…”
