Common hepatic artery (CHA) pseudoaneurysm is a rare and po tentially life-threatening complication after pancreaticoduodenec tomy, and the possible cause is unclear. We report a case of intra peritoneal hemorrhage after pancreaticoduodenectomy who was discharged after embolization under DSA. We consider that this complication may be related to iatrogenic injury.

1.1. Introduction: Post-COVID-19 syndrome is a condition that develops in the patients recovered from COVID-19 resulting into the cumulative effects of dyspnoea and impaired lung function. Notably, higher concentrations of HA have been found in patients with respiratory inflammation and COVID-19. As, bovhyaluroni dase azoximer (Longidaza®) catalyses the hydrolysis of HA, the treatment has the potential to lower HA concentrations and im prove lung function in patients with post-COVID-19 syndrome.
