Suggestions and summaries on multi-center management of acute aortic dissection surgery during COVID-19 epidemic in Hubei province / 中华胸心血管外科杂志

ABSTRACT

Objective:Since December 2019, novel coronavirus infection has occurred in Hubei province and spread throughout the country quickly. This new crown viral pneumonia was named as coronavirus disease of 2019 (COVID-19) by WHO. However, at present, there is a high incidence of acute aortic dissection in winter and spring. How to prevent the spread of the epidemic and choose the appropriate treatment is an important topic for the patients with acute aortic dissection.Methods:From January 16, 2020 to February 26, 2020, a total of 37 of acute aortic dissection operations were carried out in several cardiovascular surgery centers in Hubei Province. There were 18 cases of Stanford type A aortic dissection and 19 cases of Stanford type B aortic dissection. There were 10 cases (55.55%) with ascending aorta replacement and 7 cases (38.89%) with Bentall procedure for aortic root surgery, and total arch replacement with stented elephant trunk implantation were performed in 14 cases (77.8%). In 19 patients with Stanford type B aortic dissection, thoracic endovascular aortic repair was performed, with the left subclavian artery chimney technique in 2 cases.Results:No deaths occurred within 30 days of hospitalization. Preoperative nucleic acid testing excluded 7 cases of novel coronavirus infection, and 3 suspected cases underwent emergency surgery. the three-level protective standard was adopted in the majority of the surgeries(62.2%, 23/37), and 11 patients were negative in the reexamination of viral nucleic acid after the operation.Conclusion:During the epidemic period, patients with acute aortic dissection should be carefully identified with actife COVID-19 before surgery. The treatment principles-" prevention and control of pneumonia epidemic should be emphasized, conservative medical management should be taken in the comfirmed cases, the selective operation should be delayed as far as possible, and the operation should be reasonable performed in critical cases" should be followed, which can save patients' lives to the greatest extent and prevent the spread of the virus.
