Key result
EVAR in hostile proximal necks yields ~99% technical success but angulation is linked to mid-term endoleaks.
Why the study?
Does endovascular abdominal aortic aneurysm repair achieve technical success and safety in patients with hostile proximal neck anatomy?
Does endovascular abdominal aortic aneurysm repair achieve technical success and safety in patients with hostile proximal neck anatomy?
Endovascular repair of abdominal aortic aneurysms with hostile proximal neck anatomy has a high technical success rate (98.86%), though specific anatomical features predict mid-term complications.
Supports endovascular repair for abdominal aortic aneurysm with hostile proximal neck anatomy; extends evidence to these patients but associates angulation with increased mid-term endoleak risk.
Endovascular abdominal aortic aneurysm repair in hostile anatomy of the proximal landing zone is a safe and effective method of treatment, with a technical success rate of 98.86%. It was found that angulation in the area of the proximal aneurysmal neck contributed to the development of endoleaks in the mid-term follow-up period, with thrombotic masses in the region of the proximal neck of the aneurysm being predictive factors for thrombosis of the stent-graft limbs.
