He is currently a postdoctoral researcher in the Department of Cardiovascular Surgery at Peking University Third Hospital, focusing on minimally invasive coronary artery bypass grafting (MICS-CABG) and related surgical techniques. Dr. Song has contributed to the establishment of national clinical databases and research initiatives on MICS-CABG in China and has published multiple papers in this field.

Description

Background: The modality of thoracoabdominal aortic repair (TAAR) is mainly based on left heart bypass (LHB) in western countries, while in our team, it is mainly based on a unique technique, off-pump aortic self-bypass, and there is a lack of systematic reports and long-term results. To describe the operative technique and summarize the patient characteristics and outcomes of TAAR with off-pump aortic self-bypass technique in our team in the last decade. Meanwhile, to explore the influence of different previous surgical history on prognosis.
Methods: 137 consecutive patients who received TAAR with off-pump aortic self-bypass technique by single surgeon from 2012 to 2022 were retrospectively analyzed. Operative details were described and data were grouped according to previous surgical history. Early operative mortality and adverse events were summarized. Survival over time was estimated by the Kaplan–Meier curve.
Results: The average age of the cohort was 42.39±11.76 years old, 70.07% were male. 63 (46%) patients had no previous surgery, 53 (39%) patients had total arch replacement with frozen elephant trunk (TAR_FET), and 21 (15%) patients had thoracic endovascular aortic repair (TEVAR). Operative mortality was 4.38%, the incidence of early paraplegia was 6.57%, and previous surgery had no significant effect on prognosis (p=0.294). Cumulative survival was 92.1% at 3 years and 90.8% at 5 years.
Conclusions: The off-pump aortic self-bypass technique for TAAR is feasible regardless of previous surgery, as long as there are no complicating factors. And the early outcomes are satisfactory and the long-term outcomes are reliable.
