Background: We evaluated the application of a new combined surgical and endovascular technique for the treatment of thoracic aortic aneurysms and dissections. The technique is used to treat extensive aortic disease by a single-stage procedure. Surgical outcomes and follow-up data are summarized and analyzed.

Methods: Between August 2005 and December 2006, 7 patients (2 women), aged 62 ± 11 years, with aortic pathologies (5 dissections, 2 aneurysms) underwent replacement of the ascending aorta and the aortic arch and simultaneous stent graft implantation into the descending aorta. The stent graft used was the E-vita open endoluminal stent graft (Jotec Inc, Hechingen, Germany), which was implanted using the technique of circulatory arrest and moderate hypothermia with selective antegrade cerebral perfusion. The stent graft was deployed under visual guidance through the open aortic arch into the true lumen.

Results: Intraoperative antegrade stenting of the descending aorta combined with the distal ascending aorta and aortic arch repair was performed successfully in all patients. The survival rate was 100%. One patient had a postoperative neurologic deficit but recovered completely. Four patients had fully thrombosed perigraft spaces within 11 days, whereas 1 patient showed complete obliteration of the false lumen at the 3-month control.

Conclusions: The combined surgical and endovascular technique described in this report proved feasible for the treatment of extended aortic lesions. It serves as an additional option for aortic repair in a single-stage method and is associated with no elevated risk for the patient.
