Hybrid treatment of aortic arch aneurysms.
OBJECTIVE
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.


CONCLUSIONS
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.
