Abstract
AIM: The epidemic of COVID-19 has greatly affect the world health care system, particular measures have been taken not only to provide safety for health care providers but also to maintain the treatment quality. We evaluate the effect of COVID-19 epidemic to acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) received endovascular treatment (EVT) in our institution. METHODS: AIS patients with LVO who underwent EVT in the period of January 1st to April 30th between 2015 and 2020 from our stroke center. The baseline characteristics, working flow time, safety and efficacy outcome and the hospitalization status were retrospectively reviewed, compared and analyzed. RESULTS: There is significant decline in the number of AIS patients with LVO treated compared with the previous year (36 Vs 72 patients) during the epidemic period. The door to puncture time was significantly prolong (225 minutes versus 115 minutes) as well as the length of hospital stay with increase of the hospitalization costs (P < 0.05 for all). There is no significant difference on the safety and efficacy outcome, such recanalization rate, incidence of intracranial hemorrhage, functional independence and mortality during the epidemic (P > 0.05 for all). CONCLUSIONS: Prolongation of the working time flow during the COVID-19 epidemic did not influence the safety and efficacy of EVT in AIS patients with LVO. However, special policy and particular measures in this circumstances is still need to evolve to improve the treatment quality.
