1990年阿根廷医生Parodi的首次成功的经股动脉植入腔内移植物治愈一例腹主动脉瘤，在此后10余年中，腔内技术的发展使主动脉疾病的治疗模式发生了巨大的改变，例如腹主动脉瘤的治疗，在发达国家的多数血管外科中心利用腔内移植物进行的腔内隔绝术已经替代了一半以上的开腹手术，在主动脉夹层和胸主动脉瘤的治疗中，腔内技术的使用也日益普及。
ObjectiveTo summarize clinical experience and early to mid-term results of modified aortoplasty with external wrap for aneurysmal dilatation of the ascending aorta with or without heart valve disease. MethodsClinical data of 27 patients with aneurysmal dilatation of the ascending aorta who underwent modified aortoplasty with external wrap in Department of Cardiovascular Surgery, Fujian Provincial Hospital from January to October 2003 were retrospectively analyzed. There were 19 male and 8 female patients with their age of 35-71 (57±9)years and body weight of 42-90 (59±11)kg.There were 23 patients with aortic valve disease including 3 patients with bicuspid aortic valve. There were 4 patients in New York Heart Association function class Ⅰ, 9 patients in class Ⅱ, 12 patients in class Ⅲ, and 2 patients in class Ⅳ. Preoperative ascending aortic diameter (AAOD)was 40.0-59.1 (46.4±4.8)mm, left ventricular end-diastolic diameter was 42.5-70.7 (56.9±8.3)mm, and left ventricular ejection fraction (LVEF)was 57.7%±8.0%. Patients were followed up with echocardiography to examine changes of AAOD and left ventricle. ResultsCardiopulmonary bypass (CPB)time was 121.2±52.6 minutes, and aortic cross-clamping time was 70.6±29.7 minutes. Two patients received modified aortoplasty without CPB. There was no in-hospital death.Among the 25 patients who received modified aortoplasty under CPB, 1 patient had cerebral infarction and another patient had hypotension and arrhythmia postoperatively.Postoperative AAOD (36.3±3.4 mm)was significantly smaller than preoperative AAOD (46.4±4.8 mm, t=1.675, P < 0.05). Twenty-four patients were followed up from 1.0 to 120.5 months (average, 35.5 months). During follow-up, no cardiac-related death or reoperation was found. Two patients died of pneumonia, and another 2 patients died of cerebral hemorrhage. One patient had upper gastrointestinal bleeding. Aneurysmal dilatation of the ascending aorta recurred in 1 patient 3 years after discharge with AAOD of 49.9 mm. AAOD at 1 year (40.3±4.3 mm)and 3 years (40.3±5.6 mm)after discharge were significantly smaller than preoperative and postoperative AAOD (P < 0.05). ConclusionModified aortoplasty with external wrap is a good surgical procedure for aneurysmal dilatation of the ascending aorta with or without valve disease, and early to mid-term results are satisfactory.
Objective To evaluate the importance of "one-stop" hybrid operating room in the individualized treatment of aortic pathology. Method We retrospectively analyzed the clinical data of 247 patients of aortic pathology who were operated in the hybrid operating room in our hospital from January 2013 through December 2014. There were 193 males and 54 females at age of 24-83(54±12) years. Results Thoracic or abdominal endovascular aortic repair (TEVAR/EVAR) was applied in 132 patients, including 122 simple patients and 10 complexes. Fenestrated TEVAR was applied in 61 patients. Hybrid operation was done in 54 patients. Perioperative death occurred in 9 patients (3.6%). Perioperative complication rate was 11.7% (29/247) . The patients were followed up for one year. During follow-up, five patients were dead. The one-year survival rate was 98.0% (242/247) . Conclusions "One-stop" individualized treatment of aortic pathology shows its advantage, yet long-term result still needs to be followed up.
ObjectiveTo analyze the etiologies, operation techniques and outcomes of redo aortic root replacement after cardiac surgery.MethodsBetween December 2013 and December 2019, 30 patients who had at least one previous cardiac operation received aortic root replacement in our hospital, including 20 males and 10 females with an average age of 50.4±12.7 years. The mean time interval between this operation and the previous one was 8.0±8.5 years. The principal indication for surgery was aortic sinus dilatation and ascending aortic aneurysm in 14 patients (47%), acute aortic dissection in 5 patients (17%), pseudoaneurysm in 3 patients (10%), prosthetic valve endocarditis in 4 patients (13%), prosthetic leakage in 4 patients (13%). Bentall procedure was used in all 30 patients, with concomitant mitral valve plasticity or replacement in 5 patients, tricuspid valve plasticity in 6 patients, coronary artery bypass grafting in 3 patients, and total aortic arch replacement and elephant trunk procedure in 2 patients.ResultsThe mean cardiopulmonary bypass time was 96-296 (161.3±43.0) min, and the mean aortic occlusion time was 48-117 (85.7±20.4) min. There were 5 in-hospital deaths with an overall in-hospital mortality of 17%. The causes of deaths were low cardiac output syndrome in 2 patients and septic shock in 3 patients. The follow-up time was 3-75 (33.5±21.1) months. Three patients died during the follow-up, 1 patient died of septic shock and 2 died of cerebral hemorrhage.ConclusionRedo aortic root replacement is difficult to deal with, and the risk is high. Preoperative evaluation is required, appropriate surgical approach, adequate myocardial protection, and a complete surgical plan are essential to ensure the success of the operation.
Heritable aortic disease (HAD) is characterized by thoracic aortic aneurysm/dissection with strong genetic predisposition and high clinical phenotypic heterogeneity. HAD is one of the main causes of sudden death. Early diagnosis of this disease is difficult because of atypical clinical symptoms, leading to the deterioration of disease with the development of aortic aneurysm, aortic dissection or sudden death. Genetic testing plays an important role in the early diagnosis, standardized follow-up, screening of family members, genetic counseling and individualized treatment of HAD. This review was focused on the application of genetic testing in the standardized diagnosis and treatment of HAD.
