ObjectiveTo investigate the feasibility, effectiveness and durability of aortic sinoplasty in repairing aortic roots of patients with acute type A aortic dissection.MethodsFrom January 2014 to July 2017, 43 consecutive patients with acute type A aortic dissection underwent aortic sinoplasty to repair aortic root in our institution, including 34 males and 9 females, aged 32-65 (50.1±8.1) years. The perioperative and follow-up data were retrospectively analyzed, and statistical analysis on the preoperative, postoperative and follow-up ultrasound indicators was performed.ResultsThirty-day mortality was 4.7%. Preoperative aortic regurgitation was corrected and false lumen was eliminated immediately after operation in all patients. There was no late death, or aortic root or valve re-intervention and two patients were lost during a follow-up of 18-45 (27.9±6.7) months. There was no residual dissection found. No patients had significant dilation of aortic root. No statistically significant difference was found when comparing the maximum of root diameter and aortic regurgitation grade between at discharge and follow-up.ConclusionAortic sinoplasty for aortic root repair in acute type A aortic dissection is a simple and reliable technique and demonstrates excellent early outcomes.
Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.
ObjectiveTo summarize the surgical strategy of reoperative aortic root replacement after prior aortic valve replacement (AVR), and analyze the early and mid-term outcomes.MethodsFrom April 2013 to January 2020, 75 patients with prior AVR underwent reoperative aortic root replacement in Fuwai Hospital. There were 54 males and 21 females with a mean age of 56.4±12.7 years. An emergent operation was performed in 14 patients and an elective operation in 61 patients. The indications were aortic root aneurysm in 38 patients, aortic dissection involving aortic root in 30 patients, root false aneurysm in 2 patients, prosthesis valve endocarditis with root abscess in 2 patients, and Behçet's disease with root destruction in 3 patients. The survival and freedom from aortic events during the follow-up were evaluated with the Kaplan-Meier survival curve and the log-rank test.ResultsThe operative procedures included prosthesis-sparing root replacement in 45 patients, Bentall procedure in 26 patients, and Cabrol procedure in 4 patients. Operative mortality was 1.3% (1/75). A composite of adverse events occurred in 5 patients, including operative death (n=1), stroke (n=1), and acute renal injury necessitating hemodialysis (n=3). The follow-up was available for all 74 survivors, with the mean follow-up time of 0.5-92.0 (30.3±25.0) months. Four late deaths occurred during the follow-up. The survival rate at 1 year, 3 years and 6 years was 97.2%, 91.4% and 84.4%, respectively. Aortic events developed in 2 patients. The rate of freedom from aortic events at 1 year, 3 years, and 6 years was 98.7%, 95.0% and 87.7%, respectively. There was no difference in rate of survival or freedom from aortic events between the elective patients and the emergent patients.ConclusionReoperative aortic root replacement after prior AVR can be performed to treat the root pathologies after AVR, with acceptable early and mid-term outcomes.
