Abstract:
Objective To study surgical indication, technique for treating acute Stanford type A aortic dissection involving repair of the aortic arch using Sun’s procedure with preservation of autologous brachiocephalic artery. Methods We retrospectively analyzed the clinical data of 28 consecutive patients (23 males, 5 females) who underwent operations on acute Stanford type A aortic dissection using Sun’s procedure with preservation of autologous brachiocephalic artery in our hospital between August 2011 and October 2013. The mean age was 29-62 (47±8) years. There were 26 patients with hypertension and 2 patients with Mafan syndrome. Sun’s procedure with preservation of autologous brachiocephalic artery was performed in all patients, concomitant procedure included aortic root replacement (Bentall) in 4 patients, aortic root replacement (Bentall) and mitral valve replacement (MVR) in 1 patient, aortic valsalva sinus plasty in 6 patients. Results The cardiopulmonary bypass time was 167±37 min. The cross clamp time was 80±22 min. Selective cerebral perfusion time was 29±5 min. One patient died postoperatively from acute hepatic failure. Two patients suffered from transient neurologic deficit and recovered after treatment during follow-up. Computed tomography angiography (CTA) of aorta was performed in each patient before discharged from the hospital. The patency of the anastomotic site at brachiocephalic artery was identified. Descending aortic true lumen was significantly expanded. There was only 2 patients with endoleak and total thrombosis of false lumen was found near stent graft with 25 patients. The 27 patients were followed up for 47 (36-62) months. One patient with descending thoracic aortic dilatation underwent thoracoabdoninal aortic replacement. One combined with acute endometrial tear underwent thoracic endovascular aortic repair. Conclusion Sun’s procedure with preservation of autologous brachiocephalic artery is safe and effective in the treatment of acute Stanford type A dissection in patients without brachiocephalic artery involved. Low mortality and complication rate are achieved, but the long-term results need the further follow-up.
