Disruptive innovation is a process where technology, products, or services are transformed or replaced by a better innovative solution. This superiority must be perceived by users as being more accessible, simple, or convenient. Patient Blood Management (PBM) suggests the notion of the timely application of evidence-based medical and surgical concepts designed to maintain hemoglobin concentration, optimize hemostasis and minimize blood loss thus improving patient outcomes, that is, they are aimed at changing patient care, assisting healthcare professionals in disease treatment and cure as well as risk reduction. Thus, innovation in PBM is a new frontier to be pursued. The management of patient's blood and preparation for surgical procedures is an enormous challenge that helps minimize anemia and control blood loss during hospitalization, ensuring they are discharged in adequate clinical conditions. Until 2016, there was no standard definition or classification for the severity of intraoperative bleeding or hemostasis. The development of a PBM program when combined to the development of a bleeding scale such as the validated Intraoperative Bleeding (VIBe) Scale, represents a new solution that balances perioperative blood loss and more importantly, enables a critical cultural change which can be useful to help surgeons communicate anticipated hemostatic needs throughout a case and therefore enhance efficiency leading to better outcomes.</p>","PeriodicalId":94026,"journal":{"name":"Hematology, transfusion and cell therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142304649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was estimated that approximately 40-50 % of patients treated with imatinib will require treatment with a second-generation or third-generation tyrosine kinase inhibitor to achieve an optimal response. The treatment duration, increased patient survival, and aging of the population receiving tyrosine kinase inhibitors raise concerns as to long-term toxicities, such as an elevated cardiovascular risk and a higher rate of comorbidities. Ponatinib is a highly potent third-generation tyrosine kinase inhibitor that was shown to be effective in patients with a wide range of ABL mutations, including T315I. The use of ponatinib is associated with significant vascular toxicity, including peripheral arterial occlusive disease, ischemic heart disease, cerebrovascular accidents, and venous thromboembolism. This review discusses the vascular toxicity of ponatinib and presents a comprehensive panel of tests for the evaluation of patients requiring ponatinib therapy. Moreover, the management of patients with cardiovascular risk factors who receive ponatinib is discussed.
