Aim. Isolated iliac artery aneurysm is a rare pathology that is often asymptomatic for long periods; this late diagnosis exposes patients to a high risk of death following aneurysm rupture. The aim of this study was to establish the most suitable diagnostic approach, the correct indications for treatment, and the most appropriate tactics and surgical technique.
Methods. Twenty-eight patients were observed over 13 years. Aneurysmal involvement was unilateral in 22 cases and bilateral in the remaining 6 patients. Preoperative diagnostic tests included eco-colour Doppler (ECD) and angio-CT in all cases, with angio-MR and angiography as more selective procedures. Seventeen patients underwent conventional open surgery with prosthetic replacement of the aneurysmatic tract, 7 patients were treated using endovascular exclusion, and lastly 4 were monitored over time.
Results. There was no perioperative mortality for either treatment. During the postoperative period following conventional open surgery, complications included one case of severe respiratory failure, one microembolism of the lower limb, and 2 periprosthetic hematoma. During the follow-up, we observed one pseudo-aneurysm, 3 cases of retrograde ejaculation and one patient with erectile dysfunction after traditional surgery; there was one minor endoleak after endovascular exclusion.
Conclusion. Our experience suggests that ECD is a useful method for arriving at an early diagnosis, while angio-CT imaging is essential for a correct preoperative study. Aneurysms with a diameter equal or greater than 3 cm or that present annual increases in excess of 5 mm represent a correct indication for treatment. Conventional open surgery is the treatment of choice for young patients in good general conditions. Endovascular exclusion is indicated when the patient’s clinical conditions contraindicate open surgery and the morphology of the aneurysmal arterial district allows the endoprosthesis to be safely implanted.
