Background. Aim of this study was to evaluate the results of endovascular repair of abdominal aortic aneurysm (AAA) in patients considered not suitable for traditional open surgical repair because of the high anesthesiological risk.
Methods. We have retrospectively evaluated the result of the endovascular treatment of 11 patients with AAA of more than 6 cm diameter and high surgical risk due to cardiac hypokinesia and/or respiratory insufficiency. Patients were selected by a team composed of vascular surgeons and vascular radiologists who decided to implant the graft according to anatomical features of the AAA and of the iliac arteries. The treatment was performed in loco-regional anesthesia. The main end-points were: implantation success, mortality, morbidity, the absence of endoleak during the follow up that lasted two years.
Results. All the grafts were successfully implanted. There were no complications caused by anesthesiological manouvres. We had a minor intra-operative vascular complication and we performed three adjunctive endovascular procedures. A patient died of acute myocardial infarction, in the post operative period. Mean stay was six days. Pre-discharge scan showed 3 endoleaks (type I), two of these healed spontaneously and one sealed by percutaneous endovascular treatment. During follow-up (3-24 months) no patient died. One endoleak (type II) still persists.
Conclusions. The use of loco-regional anaesthesia allows us to treat high risk patients. Following strictly the criteria of patient selection, the surgical high risk seems not to influence significantly the mid term results that are almost equal to the ones obtained in low-risk patients.
