Abstract: Vascular surgery emergencies are clinically common with critical conditions and high mortality rates, which are more difficult to be managed with increased risk during the epidemic prevention period of novel coronavirus pneumonia (COVID-19). At present, there are few reports on the principles and strategies of emergency surgery on how to treat vascular surgical emergencies. Based on the characteristics of emergency and pathological changes of vascular surgical diseases, as well as the diagnosis and treatment experience of our hospital during the COVID-19 epidemic, this paper puts forward the principle and strategy of "SEAS". By following the principles of "safe" and "effective", and the strategies of "avoidance" and "simple", the emergency treatment of vascular surgery can be carried out timely, safely and effectively while effectively preventing and controlling the epidemic situation of COVID-19.
