ObjectiveTo retrospectively analyze the surgical treatment of Stanford type A aortic dissection after coronary artery stenting, and to explore the surgical techniques and surgical indications. MethodsClinical data of 1 246 consecutive patients who underwent operations on Stanford type A aortic dissection from April 2016 to July 2019 in Beijing Anzhen Hospital were retrospectively analyzed. Patients with Stanford type A aortic dissection after coronary artery stenting were enrolled. ResultsFinally 19 patients were collected, including 16 males and 3 females with an average age of 54±7 years ranging from 35 to 66 years. There were 11 patients in acute phase, 15 patients with AC (DeBakey Ⅰ) type and 4 patients with AS (DeBakey Ⅱ) type. In AC type, there were 10 patients receiving Sun's surgery and 5 patients partial arch replacement. Meanwhile, coronary artery bypass grafting was performed in 7 patients and mitral valve replacement in 1 patient. Stents were removed from the right coronary artery in 4 patients. In this group, 1 patient died of multiple organ failure in hospital after operation combined with malperfusion of viscera. Eighteen patients recovered after treatment and were discharged from hospital. The patients were followed up for 30 (18-56) months. One patient underwent aortic pseudoaneurysm resection, one thoracic endovascular aortic repair, one emergency percutaneous coronary intervention due to left main artery stent occlusion, and one underwent femoral artery bypass due to iliac artery occlusion. ConclusionIatrogenic aortic dissection has a high probability of coronary artery bypass grafting at the same time in patients with Stanford type A aortic dissection after coronary artery stenting. Complicated type A aortic dissection after percutaneous coronary intervention should be treated with surgery aggressively.
The aortic dissection (AD) carries high mortality which increases by 1%-2% per hour after onset in untreated patients. Fifty percent of patients will die in 48 hours, and 70%-80% patients will die in 2 weeks without treatment. Moreover, acute AD during pregnancy is a rare and much catastrophic disease with high lethality for the mother and fetus simultaneously. At present, AD is so rare that most articles are mainly small cohort studies and case reports. Therefore, we reviewed literatures in order to provide clinical reference for the comprehensive treatment of AD.
Objective To summarize our experience and the early and midterm outcomes of stented elephant trunk procedure for right-sided aortic arch (RAA) with Kommerell's diverticulum (KD). Methods From April 2013 to July 2020, patients with RAA and KD who underwent stented elephant trunk procedure at our center were collected. Surgery was performed under moderate hypothermic circulatory arrest combined with selective antegrade cerebral perfusion via median sternotomy. Results A total of 8 patients were included, including 7 males and 1 female with a mean age of 51.88±9.61 years. All patients had an aneurysmal KD and aberrant left subclavian artery. Preoperative comorbidities included acute Stanford type B aortic dissection in 1 patient, aortic arch pseudoaneurysm in 1 patient, acute type B intramural hematoma in 2 patients, and coronary artery disease in 1 patient. Concomitant procedures included reconstruction of the left subclavian artery in all patients and coronary artery bypass grafting in 1 patient. The mean time of operation, cardiopulmonary bypass, aortic cross-clamping, and selective cerebral perfusion was 6.25±1.16 h, 157.75±40.07 min, 77.75±33.10 min, and 28.50±5.55 min, respectively. No intraoperative death occurred. There was 1 in-hospital death. Follow-up was completed in all patients with a mean period of 3.58±2.08 years. No late death occurred. A persistent anastomotic leak of the proximal arch was detected in 1 patient, but reintervention was not performed because neither aortic dilatation nor symptoms of tracheal and esophageal compression were observed during the follow-up. The remaining 6 patients showed positive aortic remodeling with complete thrombosis of the aneurysmal KD, and neither aortic event nor tracheal and esophageal compression occurred. Conclusion Stented elephant trunk procedure is a safe and feasible technique for selected patients with RAA and KD, which can achieve favorable early and midterm outcomes.
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.
