Who should do endovascular repair of complex aortic aneurysms and how should they do them?

Abstract

Background: Cure of aneurysms which involve the aorta at the level of the visceral arteries and the thoracoabdominal segment remains a considerable surgical enterprise with a relatively high mortality and morbidity despite improvements of the surgical procedure and anesthetic technique. Fenestrated and branched endovascular stent grafts are currently available offering an attractive less invasive option especially for most frail patients. These grafts are relatively recent, technically more demanding to insert than the current stent graft for infrarenal aneurysm and besides, given the relative low frequency of the disease, they are much less used by practitioners. Thus, unconditional widespread of this sophisticated technique may not necessarily benefit patients.

Methods: We reviewed our experiences and articles regarding this concern, 1) who should perform this new technique and 2) in what kind of setting.

Conclusion: Based on the combined complexities of 1) patients selection, 2) proper planning and manufacturing of the graft, 3) the need for outstanding imaging and operating facilities, 4) and the required endovascular skill of physicians involved in the procedure, we feel that only highly specialized centers should be allowed to perform this complex procedure.
