All of them showed preoperative newly developed neurologic deficits, left hemiplegia in 8 cases, left paraparesis in 5 cases and right paraparesis in 3 cases.Results:Aortic valve was involved in 5 patients, 2 of whom underwent AVR surgery, 2 cases of CABG and 2 cases of artificial graft bypass were performed at the same time, 1 case underwent left leg amputation postoperatively. Seven patients died after surgery.Conclusion:The results of surgical management of acute type A aortic dissection with cerebral malperfusion demonstrated high hospital mortality, which needs us to restore the cerebral perfusion as soon as possible. The specific method should be decided according to the patients' condition.

Objective:To analyze the status of treatment of aortic diseases in nine centers included in Jiangsu Aortic Registry study.Methods:Medical records of 1 105 patients who underwent surgery for aortic diseases in nine cardiovascular centers in Jiangsu province from January 1, 2019 to December 31, 2020 were retrospectively collected. According to the types of diseases, they are divided into three categories: Category Ⅰ diseases: aortic diseases requiring only simple open surgery; Category Ⅱ: aortic disease requiring complex open surgery; Category Ⅲ disease: aortic disease requiring interventional or hybrid surgery. The diagnosis and treatment of the three diseases were compared by statistical analysis.Results:Patients aged 50-59 years and 60-69 years were the most in the whole group, accounting for 291(26.3%) and 319 (28.9%), respectively. That is, the age group between 50-69 years was the main age for the incidence of aortic disease, accounting for 55.2% (610/1 105) of the total incidence. The ratio of male to female was 803∶302, and male was 72.7% (803/1 105). The perioperative mortality of patients with type Ⅰ and Ⅲ diseases was lower [1.6%(6/385) and 1.0% (4/330), respectively]. The perioperative mortality of patients with type Ⅱ diseases was significantly increased (15.5% (51/330)) due to their dangerous onset and complicated operation. The highest postoperative complications were infection 11.3% (124/1 105), acute kidney injury 8.6% (95/1 105), and neurological complications 7.0% (77/1 105), respectively.Conclusion:Individualized treatment according to the lesion site, lesion type and scope of involvement of aortic disease can achieve a satisfactory prognosis.

Objective:To investigate the postoperative complications and in-hospital mortality of reoperative cardiac surgery, and to explore the feasibility and safety of reoperative cardiac surgery.Methods:The baseline data and clinical information of patients undergoing cardiac surgery in Nanjing First Hospital from November 2012 to November 2021 were retrospectively conducted, and they were divided into the reoperative cardiac surgery group and the primary surgery group according to whether they underwent reoperative cardiac surgery using a propensity score analysis. The intraoperative indicators, postoperative complications and in-hospital mortality were compared between the two groups after matching.Results:After propensity score analysis, 146 cases were included in each of the group. In terms of intraoperative indicators, the cardiopulmonary bypass time [(141.48±47.88)min vs.(105.31±33.56)min], aortic occlusion time [87.0(70.5, 113.3)min vs. 71.5(53.0, 92.0)min], ICU stay time[2( 1, 4)days vs. 2(1, 2)days], postoperative drainage volume [750(460, 1300)ml vs. 610(410, 840)ml], postoperative transfusion of red blood cells [0(0, 3.5)U vs. 0(0, 2)U], the reoperative cardiac surgery group increased with statistically significant differences( P<0.05). Postoperative complications, the two groups had postoperative hypoxemia [15(10.3%) vs. 6(4.1%)], acute kidney injury [10(6.8%) vs. 0(0)], postoperative infection [24(16.4%) vs. 4(2.7%)], cerebral complications [7(4.8%) vs. 1(0.7%)] )], the incidence rate in the reoperative cardiac surgery group was higher with statistically significant differences( P<0.05). There was no significant difference in in-hospital mortality[7(4.8%) vs. 4(2.8%)]( P>0.05). Conclusion:The time of reoperative cardiac surgeryis is longer, postoperative recovery is slower, and postoperative complication rate is higher, but does not increase in-hospital mortality.

Objective:To summarize treatment strategies and outcomes of patient suffer from acute Stanford type A aortic dissection(ATAAD) with mesenteric malperfusion.Methods:We collected 13 patients with mesenteric malperfusion among 321 ATAAD patients underwent surgery at Nanjing First Hospital during January 2019 to September 2022. Characteristics of these patients were recorded. We analyzed their early and late clinical outcomes.Results:Two patients underwent revascularization-first strategy in hybrid operation room had no in-hospital mortality or complication related to mesenteric ischemia. There were 11 patients with central repair-first strategy. Eight patients appeared mesenteric complications and 2 of them needed extra gastrointestinal surgery. Six in-hospital mortality were recorded in central repair-first patients.Conclusion:We recommended revascularization-first strategy with followed central repair in hybrid operation room for patients suffered from ATAAD with mesenteric malperfusion. Those who underwent central repair-first strategy because of coronary artery or cerebral malperfusion and unstable hemodynamic needed percutaneous angiography of mesenteric artery.

Objective: To summarize the experience of reoperations on patients who had late complications related to previous aortic surgery for Stanford type A dissection. Methods: From August 2008 to October 2016, 14 patients (10 male and 4 female patients) who underwent previous cardiac surgery for Stanford type A aortic dissection accepted reoperations on the late complications at Department of Thoracic and Cardiovascular Surgery, Nanjing Hospital Affiliated to Nanjing Medical University. The range of age was from 41 to 76 years, the mean age was (57±12) years. In these patients, first time operations were ascending aorta replacement procedure in 3 patients, ascending aorta combined with partial aortic arch replacement in 4 patients, aortic root replacement (Bentall) associated with Marfan syndrome in 3 patients, aortic valve combined with ascending aorta replacement (Wheat) in 1 patient, ascending aorta combined with Sun′s procedure in 1 patient, Wheat combined with Sun′s procedure in 1 patient, Bentall combined with Sun′s procedure in 1 patient. The interval between two operations averaged 0.3 to 10.0 years with a mean of (4.8±3.1) years. The reasons for reoperations included part anastomotic split, aortic valve insufficiency, false aneurysm formation, enlargement of remant aortal and false cavity. The selection of reoperation included anastomotic repair, aortic valve replacement, total arch replacement and Sun′s procedure. Results: Of the 14 patients, the cardiopulmonary bypass times were 107 to 409 minutes with a mean of (204±51) minutes, cross clamp times were 60 to 212 minutes with a mean of (108±35) minutes, selective cerebral perfusion times were 16 to 38 minutes with a mean of (21±11) minutes. All patients survived from the operation, one patient died from severe pulmonary infection 50 days after operation. Three patients had postoperative complications, including acute renal failure of 2 patients and pulmonary infection of 1 patient, and these patients were recovered after treatment. Thirteen patients were finally recovered from hospital. The patients were followed up for 16 to 45 months, and no aortic rupture, paraplegia and death were observed in the follow-up. Conclusions Patients for residual aortic dissection after initial operations on Stanford type A aortic dissection should be attached great importance and always need emergency surgery, but the technique is demanding and risk is great for surgeons and patients, which need enough specification and accurate on aortic operation. More importantly, the Sun′s procedure also should be performed on the treatment of residual aortic dissection or distal arch expansion, and obtains the short- and long-term results in the future.

Objective    To analyze the clinical effect of partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection. Methods    From January 2010 to December 2015, 30 patients (25 males, 5 females) underwent partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection with involvement of aortic root. The range of age was from 27 to 72 years, and the mean age was 51.2±8.0 years. The proximal aortic dissection received partial aortic root remodeling, and the operation procedures included partial aortic root remodeling+ascending aortic replacement in 9 patients, partial aortic root remodeling+ascending aortic replacement+hemi-arch replacement in 6 patients, partial aortic root remodeling+ascending aortic replacement+Sun's procedure in 15 patients. The patients were followed up for 10 to 60 months with a mean of 37.9±3.2 months. Preoperative and postoperative degrees of aortic regurgitation were compared. Results    All patients survived from the operation, and one patient died from severe pulmonary infection 15 days after operation. The overall survival rate was 96.7% (29/30). One patient died during the follow-up. Two patients underwent aortic valve replacement in the 12th and 15th postoperative month respectively because of severe aortic regurgitation (AI). Up to the last follow-up, trivial or no aortic regurgitation was demonstrated in 24 patients, but mild aortic regurgitation occurred in 2 patients. Conclusion    The surgical treatment for aortic root pathology due to Stanford type A aortic dissection is challenging, and partial aortic root remodeling operations could restore valve durability and function, and obtains the early- and mid-term results.
