      Background: An aneurysm of the superior mesenteric artery (SMA) with a diameter of 2.2 cm was found incidentally on an ultrasound (US) examination in a 26-year-old woman. The only known risk factor was an intracranial aneurysm that was found on her grandmother’s autopsy. Based on pregnancy planning and the current literature, endovascular management with a covered stent was proposed. Case Report: Self-expandable, covered stent (Bard, Fluency®) was implanted using a single transfemoral approach. A stiff guidewire and a large sheath distorted the anatomy, which resulted in an incomplete aneurysmal neck covering. In the absence of additional covered stents, the procedure was terminated. Two weeks later, computed tomographic angiography (CTA) confirmed persistent aneurysmal perfusion due to the incomplete neck coverage. A multidisciplinary board opted for a second endovascular attempt, this time with a longer covered stent via the transaxillary approach in order to reduce anatomical distortion. Balloon, expandable, cobalt-chrome covered stent (Jotec, E-ventus BX®) was implanted in the SMA, covering the aneurysmal neck and overlapping the previously implanted covered stent. Angiography confirmed a complete exclusion of the aneurysm. A control US performed three weeks later confirmed a patent covered stent and complete aneurysmal exclusion. There was a mild median nerve damage periprocedurally that resolved in three months. The most recent US control examination, performed eleven months after the procedure, showed an excluded aneurysm and a patent covered stent. There were no clinical signs of bowel ischaemia during the follow-up period. Conclusions: Endovascular management of SMAA proved to be safe and efficient. The “access from above” is probably safer and should be considered in the majority of cases with acceptable sizes of access vessels. Mid-term results in our patient are good and life-long follow-up is planned to prevent late complications.
