Moreover, the cost of hospitalization was also reduced in the IPC group, which also improved the satisfaction of patients.</p><p><strong>Conclusion: </strong>Limb ischemic preconditioning may attenuate the severity of vein thrombosis in patients with PICC, which contributes to reducing the incidence of PICC-related thrombosis in clinical practice.</p>","PeriodicalId":19981,"journal":{"name":"Pathology & Oncology Research","volume":"30 ","pages":"1611596"},"PeriodicalIF":2.3,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11602314/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142751451","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}
