Hybrid treatment of aortic arch aneurysms

Abstract

Aim: Aim of this study was to retrospectively analyze the experience of a single center in the hybrid treatment of aortic arch aneurysms.

Methods: From January 2005 to August 2008 a hybrid treatment for complex aortic aneurysms (aortic arch, thoracoabdominal aorta or thoracic and abdominal segments at the same time) was performed in 34 patients. In 11 cases a hybrid exclusion of an aortic arch aneurysm was carried out. Perioperative results in terms of morbidity and mortality were assessed. Follow-up examination consisted of computed tomography scan and chest X-ray at discharge, 6 and 12 months, and yearly thereafter. Mid-term survival and graft-related complications were analyzed.

Results: All the patients were males with a mean age of 74 years, range 68-81. Intraoperative technical success was achieved in all the cases. At 30 days one patient died for an acute stroke. The overall 30-day mortality rate was 9.1%. One frenic nerve paralysis and one acute re-spiratory failure with pneumonia were observed with an overall 30-day major morbidity rate of 18.2%. During follow-up (mean duration 19.3 months, range 1-36) no death, reintervention, conversion, aneurysm-related complication or graft thrombosis were recorded.

Conclusion: Hybrid approaches to the treatment of complex aortic lesions involving the arch can be successfully used. However, perioperative complications remain still not irrelevant and long-term efficacy has to be proved.
