[Endovascular aneurysms repair: 100 consecutive cases outcome analysis]

To evaluate the effectiveness and clinical outcomes of endovascular aneurysm repair in a single regional centre Methods: The medical records one hundred consecutive patients who underwent elective endovascular repair of nonruptured infra-renal abdominal aortic aneurysm were retrospectively reviewed. The assessed outcomes were all-cause mortality, aneurysm-related mortality, incidence of perioperative complications and reinterventions. Patient demographics and procedure characteristics were also analysed.

The patient's mean age was 74.4 years-old. There was a male preponderance, with only 5 women treated. Two-thirds were American Society of Anesthesiologists (ASA) class ≥3. Loco-regional blockade was the anaesthetic technique most commonly used (65%). There were no perioperative deaths. Medical complications occurred in 10.3% of cases, pulmonary and cardiac being the most frequent. The 30-day reintervention rate was 6.1% (SE: 2.4%). The overall median hospital length of stay was 5 days. At 8 years, all cause mortality was 28.5%(SE: 8.5%) and aneurysm-related death was 1.3% (SE: 1.3%). During the follow-up period, 87.9% (SE: 3.7%) of patients remained free from reintervention

In our institution, EVAR is associated with no early mortality and significantly good perioperative outcomes such as low rate of systemic complications, minimal blood loss, low rate of postoperative mechanical ventilation use and short hospital stay. Although the high reintervention rate for EVAR has been confirmed in several studies, our study did not find such a high need for secondary procedures. We found a durable benefit since aneurysm-related mortality is very low and late overall survival is similar to other reports. In this study's setting, our findings support endovascular management of large AAAs.
