ObjectiveTo summarize the surgical treatment plan and experience of patients with Marfan syndrome complicated with Stanford type B aortic dissection, and to explore the treatment strategy selection.MethodsA retrospective analysis was conducted on 27 patients with Marfan syndrome complicated with thoracoabdominal aortic diseases who were treated in the department of cardiovascular surgery of our hospital from January 2013 to June 2019, including 13 males and 14 females, with an average age of 32.2±8.6 years. According to the patients' conditions, 19 of them received single pump-assisted blood transfusion combined with total thoracoabdominal aortic replacement (TAAAR), and 8 received thoracic endovascular aortic repair (TEVAR) in critically ill and pregnant patients. The patients were followed up in the outpatient clinic, and the thoracoabdominal aortic CT angiography was reexamined at 3 months, 6 months, 12 months and annually. The outcome of surgery, the incidence of intermediate cardiovascular adverse events, defined as the reoperation due to aortic or cardiac diseases, and intermediate survival rate were studied.ResultsAll 27 patients successfully completed the operation, the operation time was 60-852 (395.10±222.60) min, the spinal cord ischemia time was 14-26 (19.33±3.44) min, and the abdominal viscera ischemia time was 16-23 (19.83±1.94) min. Eight patients of TEVAR were all operated in acute phase and 19 patients of TAAAR in chronic phase. Two early postoperative deaths occurred in TEVAR patients. One died of puerperal infection and multiple organ dysfunction after cesarean section at the same time. After TEVAR, type A dissection re-ocurred in one patient. The family member gave up the treatment, and the patient died of the dissection ruptured after cesarean section. During the average follow-up of 47.6±36.7 months, 1 patient died of cerebrovascular accident and 9 patients were reoperated for adverse cardiovascular events, including 4 in TEVAR and 5 in TAAAR.ConclusionTAAAR is the first choice for the treatment of Marfan syndrome combined with thoracoabdominal aortic diseases. TEVAR is easy to operate, with a low incidence of early mortality and complications, but has the risk of internal leakage and avulsion, and a high reoperation rate in the middle stage, so it can be used for high-risk elderly patients not suitable for open surgery, or as a bridge therapy for emergency patients before open surgery.
ObjectiveTo investigate the risk factors and prevention strategies of postoperative delirium in Stanford B aortic dissection. MethodsClinical data of the patients diagnosed with Stanford B aortic dissection and undergoing endovascular aortic repair from January 2020 to August 2021 in our department were retrospectively collected. Patients were divided into a non-delirium group and a delirium group according to the presence of postoperative delirium. The risk factors for postoperative delirium after Stanford type B aortic dissection and the protective effect of dexmedetomidine on delirium were analyzed. ResultsA total of 659 patients with Stanford type B aortic dissection were enrolled, including 540 males and 119 females with a median age of 58.00 (41.00, 75.00) years. There were 450 patients in the non-delirium group, and 209 patients in the delirium group. There was no statistical difference in gender, body mass index, hypertension, hyperlipidemia, smoking and drinking history, cholesterol triglyceride level, or creatinine glomerular filtration rate (P＞0.05). Age was an independent risk factor for postoperative delirium in Stanford type B aortic dissection (OR=1.392, 95%CI 1.008-1.923, P=0.044). Moreover, whether dexmedetomidine was used or not had no effect on the duration of postoperative delirium (χ2=4.662, P=0.588). Conclusion Age is an independent risk factor for postoperative delirium in patients with Stanford type B aortic dissection. The incidence of postoperative delirium in young patients is lower than that in the patients with middle and elderly age, and it may be of reference value to prevent postoperative delirium. Dexmedetomidine has no significant effect on controlling the duration of postoperative delirium.
ObjectiveTo report our clinical experience and outcomes of thoracic endovascular aortic repair (TEVAR) for acute Stanford type A dissection using ascending aorta replacement combined with implantation of a fenestrated stent-graft of the entire aortic arch through a minimally invasive technique. MethodsFrom 2016 to 2020 in our hospital, 24 patients (17 males and 7 females, aged 45-72 years) with complicated Stanford type A aortic dissection, underwent replacement of the proximal ascending aorta with TEVAR. None of the patients with dissection involved the three branches of the superior arch, and all patients were replaced with artificial blood vessels of the ascending aorta under non-hypothermic cardiopulmonary bypass, preserving the arch and the three branches above the arch, and individualized stent graft fenestration. ResultsSurgical technical success rate was 100.0%. There was no intraoperative complication or evidence of endo-leak in 1 month postoperatively. Hospital stay was 10±5 d. During postoperative follow-up, the stent was unobstructed without displacement, the preserved branch of the aortic arch was unobstructed, and the true lumen of the descending aorta was enlarged. Conclusion This hybrid technique by using TEVAR with fenestrated treatment is a minimally invasive and effective method to treat high-risk patients with acute Stanford type A aortic dissection.
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.
