The anatomical variations included 6 right accessory renal arteries, 8 left accessory renal arteries, and 1 celiac artery variant. Stent-grafts were fenestrated, branched or combined in 6, 5, or 1 patients, respectively. The mean operating time was 346\u00b1120 minutes, the mean fluoroscopy time was 80\u00b129 minutes, and the mean radiation dose area product was 430\u00b1219 Gy\u00b7cm\n                      <jats:sup>2<\/jats:sup>\n                      . The mean contrast volume was 129\u00b145 mL. The total number of TVs was 64; 5 TVs in 9 patients, 6 in 2 patients, and 7 in 1 patient. Technical success was achieved in all cases. The mean intensive care unit stay was 6\u00b15 days, and the mean total hospital stay was 14\u00b110 days. One patient died early (30-day). Early morbidities included respiratory complication in 1 patient, renal insufficiency in 1 patient, and wound infection in 2 patients. No spinal cord ischemia, stroke, or bowel ischemia occurred. Early computed tomography angiography showed 100% patency of the bridging covered stents and TVs. The mean follow-up was 13\u00b14.3 months. No mortality or adverse major event occurred during the follow-up. Two patients with developed type Ic endoleak related to 1 right renal artery and 1 celiac artery covered stent. Patency of the TVs during follow-up was 100%.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n
