PAD is one of the most important underlying factors in the development of diabetic foot. The COVID-19 pandemic has also caused an increase in cardiovascular complications in those with chronic diseases, including diabetics, due to both the thrombophilic course of the viral disease and the lockdown measures applied for prevention. Since both COVID-19 and diabetes mellitus predispose to thrombosis, PAD is likely to have a more severe course in diabetic patients with COVID-19. The aim of our study is to discuss the complications, prophylaxis, and treatment of PAD, which is a serious complication of diabetes, during the pandemic period.</p>","PeriodicalId":50062,"journal":{"name":"Journal of Research in Medical Sciences","volume":"29 ","pages":"35"},"PeriodicalIF":1.5,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11376723/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142141635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
