Combined Interventional and Surgical Treatment for Acute Aortic Type A Dissection
Surgical repair and endovascular stent-graft placement are both therapies for thoracic aortic dissection. A combination of these two approaches may be effective in patients with type A dissection. In this study, we evaluated the prognosis of this combined technique. From December 2003 to December 2006, 15 patients with type A dissection were admitted to our institute; clinical data were retrospectively reviewed. Follow-up was performed at discharge and approximately 12 months after operation. Endovascular stent-graft placement by interventional radiology and surgical repair for reconstruction of aortic arch was performed in all patients. Total arch replacement for distal arch aneurysm was carried out under deep hypothermia with circulatory arrest; antegrade-selected cerebral perfusion was used for brain protection. Four patients concomitantly received a coronary artery bypass graft. Hospital mortality rate was 6.7%; the patient died of cerebral infarction. Neurological complications developed in two patients. Multi-detector-row computed tomography scans performed before discharge revealed complete thrombosis of the false lumen in six patients and partial thrombosis in eight patients. At the follow-up examination, complete thrombosis was found in another three patients, aortic rupture, endoleaks, or migration of the stent-graft was not observed and injuries of peripheral organs or anastomotic endoleaks did not occur. For patients with aortic type A dissection, combining intervention and surgical procedures is feasible, and complete or at least partial thrombosis of the false lumen in the descending aorta can be achieved. This combined approach simplified the surgical procedures and shortened the circulatory arrest time, minimizing the necessity for further aortic operation.
