Background According to studies, coronavirus disease 2019 (COVID19) infection is linked to an elevated risk of venous thromboembolism (TE). The frequencies of overall COVID19 thrombotic events and the influence of TE on COVID19 mortality, however, are unknown. Although respiratory symptoms are the most common symptom of the disease, evidence is growing suggesting that it is linked to coagulation system malfunction, which puts patients at risk for venous and arterial TE and higher mortality as well. Materials and methods A retrospective cohort study was conducted on 50 end-stage renal disease patients on maintenance hemodialysis (25 patients with confirmed COVID19 infection and 25 patients without COVID19 infection) to determine the incidence of vascular access thrombosis among patients with COVID19 during a 3-month period. Risk factors for mortality and severity were considered as secondary outcomes. Patients with previous history of vascular access dysfunction were excluded from the study. Results In all, 24% of COVID19-positive patients (n=6) developed vascular access thrombosis during 3 months of follow-up while no one of the COVID19-negative patient developed access thrombosis. The incidence of vascular access thrombosis was statistically higher in the COVID19 positive group (p value < 0.022). The incidence of vascular access thrombosis was significantly can u please add this part : increased in patients who had lymphopenia, elevated LDH, also it was more common in patients who needed mechanical ventilation and who had severe diseaseConclusion The incidence of vascular access thrombosis was statistically higher in the COVID19 positive group (p value < 0.022).
