Abstract

Aim

The elective endovascular treatment of abdominal aortic aneurysm (AAA) is nowadays a daily routine practice in selected patients. The traditional treatment of ruptured abdominal aortic aneurysm (rAAA) has a peri-operative mortality of 40–50% that has not changed in the last 20 years. Nowadays, the endovascular repair may reduce mortality, hospitalization and sanitary costs.

Methods

The study included 14 patients affected by AAA who came to the Emergency Department because of hemodynamic shock (nine patients) or back pain (five patients). All patients underwent a CT angiography before surgery. Forty-two percent of the patients presented with shock (systolic pressure ≤70 mm Hg) in the operating room, and they underwent an endovascular aortic repair (EVAR) as an emergency procedure. Five bifurcated endoprotesis and nine uniliac protesis making a femoro-femoral bypass to revascularize the excluded limb were made. Patients underwent a follow up with CT angiography one month and then six months after surgery and if no problems were detected, patients underwent a follow-up every year.

Results

Two cases were immediately converted to open surgery because of failed EVAR. Four patients (28%) died after surgery because of multi-organ failure (MOF). The mean hospitalization was 12 days (range 3–21 days). We observed only one case of first-type endoleak at the 1-month follow up and we successfully treated it with a proximal cuff.

Conclusion

In our experience, the intention-to-treat protocol for rAAA offered acceptable results in terms of mortality rates. Multicenter studies are necessary to establish the role of endovascular treatment in patients with rAAA.
