  • Treatment of acute Stanford type A aortic dissection using the Sun’s procedure with preservation of autologous brachiocephalic artery

    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.

  • Repair of type Ⅰa endoleak after thoracic endovascular aortic repair

    Objective To retrospectively review our experience of correction of type Ⅰa endoleak after thoracic endovascular aortic repair(TEVAR). Methods From August 2009 to May 2016, 29 patients with type Ⅰa endoleak after TEVAR (25 males, 4 females at mean age of 56±10 years (range, 41–86 years) underwent treatment: open surgery in 15 patients (an open surgery group), hybrid aortic arch repair in 6 patients (a hybrid group) and cuff extension in 8 patients(a cuff group). A history of hypertension was noted in 25 patients, diabetes mellitus in 3 patients, coronary artery disease in 3 patients, lung infection in one patient, aortic root aneurysm in one patient and aberrant right subclavian artery in one patient. Results In the open surgery group, no death was observed. Continuous renal replacement therapy and re-intubation was done in one patient and drainage of pericardial effusion in one patient. No death was noted in the hybrid group and persistent type Ⅰa endoleak in one patient. In the cuff group, thrombosis of the left common artery was noted in one patient and bypass of the left axillary artery to the left axillary artery and the left common carotid artery was done. Unfortunately, he died of cerebral infarction and total in-hospital death rate was 3.4% (1/29). Bypass of the left axillary artery to the left axillary artery was done in one patient with left upper limb ischemia. There were 4 (14.2%) deaths during follow-up: 3 deaths in the open surgical group and one death in the cuff group. Endoleak was observed in one patient in the hybrid group and one in the cuff group. Conclusion The corresponding procedure, including open surgery, hybrid aortic arch repair or cuff extension, is scheduled to be done according to the characteristics of type Ⅰa endoleak. Satisfactory outcomes are achieved in patients with typeⅠa endoleak.

  • Surgical treatment of distal aortic arch lesions using stented elephant trunk implantation combined with transposition of left subclavian artery to left common carotid artery

    Objective To evaluate the short- and middle-term outcomes of surgical treatment for distal aortic arch lesions using stented elephant trunk implantation combined with transposition of left subclavian artery to left common carotid artery. Methods The clinical data of 14 patients with distal aortic arch lesions undergoing stented elephant trunk procedure with left subclavain artery transposition under hypothermic cardiopulmonary bypass (CPB) with antegrade selective cerebral perfusion from May 2009 to November 2015 in our hospital were retrospectively reviewed. All of them were males with a mean age of 52±14 years ranging from 20 to 69 years. Hypertension was observed in nine patients, coronary artery disease in five and prior cerebral infarction in one. History of percutaneous coronary intervention was noted in one patient, history of Bentall operation in one, ligation of patent ductus arteriosus in one and endovascular aneurysm repair in one. Results There was no hospital death. Concomitant procedures included coronary artery bypass grafting in two patients and plasty of the ascending aorta replacement in one. Mean duration of mechanical ventilation and ICU stay was 21±7 h and 43±19 h, respectively. All patients survived and were discharged. One patient was lost to follow-up and no patient died during the follow-up. Postoperative computed tomography revealed good patency of the anastomotic site between the left subclavian artery and the left common carotid artery. Conclusion Stented elephant trunk procedure with left subclavain artery transposition obtains satisfactory surgical results in patients with distal aortic arch lesions.
