Objective To study the mid-term and long-term postoperative results of Bentall procedure in patients with Marfan syndrome. Methods From February 2009 to July 2016, ten adolescent patients (mean age of 12.30±2.31 years ranged 9-16 years, mean height of 172.50±12.55 mm, mean weight of 48.60±17.08 kg) underwent Bentall procedure in our hospital. All these teenage patients were with Marfan syndrome, 6 boys and 4 girls. Five of them underwent mitral valve replacement procedure at the same time while 2 of them with tricuspid valvuloplasty. Results No mortality was found in hospitalization. One patient suffered respiratory failure after surgery. No renal failure, mediastinal infection or re-operation caused by bleeding were observed. All were well followed up for 62 months. One died of malignant arrhythmia, the other were in good condition with the latest interview. Conclusion Teenage patients with Marfan syndrome who underwent Bentall procedure have favorable outcomes in mid-term and long-term follow-up, they probably will not suffer anti-coagulation complications and restriction of growth.
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.
ObjectiveTo evaluate the preoperative risk factors for acute Stanford type A aortic dissection (ASTAAD) patients in our country by collecting multi-center data.MethodsWe consecutively enrolled 700 patients who underwent surgery for ASTAAD in the multi-center hospital database from January 2018 to January 2020. According to the ascending aorta size (AAS), the patients were divided into two groups: a group AAS≥55 mm and a group AAS<55 mm. Univariate and multivariate logistic regression analyses were used to investigate the related preoperative risk factors for the onset of ASTAAD.ResultsAccording to the exclusion criteria, a total of 621 patients were finally enrolled, including 453 males and 168 females with an average age of 48.24±11.51 years, and 509 (81.94%) patients had AAS<55 mm. Univariate and multivariate statistical analyses showed that smoking, hypertension, preoperative cardiac troponin I, and left ventricular ejection fraction were related to the occurrence of ASTAAD. The mortality rate of the patient during hospitalization was 13.04% (81 patients).ConclusionIn clinical practice, various preoperative risk factors affect ASTAAD patients, which should be paid attention to. Comprehensive evaluation and an individualized analysis of patients and timely prevention and intervention improve patients' survival rate.
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.
