ICIs are monoclonal antibodies that target immune checkpoints such as PD-1 (programmed cell death protein 1, as seen in nivolumab, pembrolizumab, and cemiplimab), PD-L1 (programmed cell death protein 1 ligand, as seen in atezolizumab, avelumab, and durvalumab), CTLA-4 (cytotoxic T-lymphocyte antigen 4, as seen in ipilimumab and tremelimumab), or LAG-3 (lymphocyte-activating gene 3, as seen in relatlimab), which play a crucial role in immune tolerance to cancer cells.\n\nHowever, the surge in ICI prescriptions has been accompanied by the occurrence of numerous side effects, some of which are severe or even fatal. ICIs have a different toxicity spectrum than conventional chemotherapy, and most toxicities result from excessive immunity against different organs.\n\nThis immune-mediated toxicity can affect various organ systems, including the heart and blood vessels. Pharmacovigilance data from clinical trials conducted by Bristol-Myers Squibb, which marketed ipilimumab (anti-CTLA-4) and nivolumab (anti-PD1), revealed 18 cases (0.09%) of myocarditis among 20,594 subjects.\n\nWhile cardiac complications induced by immune checkpoint inhibitors (ICIs), particularly autoimmune myocarditis, are widely described, the impact of these treatments on the vascular system remains poorly understood. However, a variety of vascular complications have been reported, ranging from vasculitis of large, medium, and small vessels to a possible increase in arterial thrombotic events, ischemic strokes, and acute coronary syndromes.\n\nThe incidence of vasculitis appears to be between 1% and 2% of patients treated with immune checkpoint inhibitors (ICIs). This is emerging as a significant signal in various pharmacovigilance studies, suggesting the involvement of immune checkpoint derepression in the pathophysiology of vasculitis. A translational study demonstrated the major role of CTLA-4 in the pathophysiology of giant cell arteritis (GCA), although the precise mechanisms involved remain to be determined. Therefore, a specific immune environment could promote the development of vasculitis, a phenomenon reproduced by ICI administration.\n\nThe increase in arterial thrombotic vascular events was primarily observed in a matched cohort study, which showed a threefold increased risk of arterial thrombotic vascular events following the initiation of ICI therapy. These thrombotic events would coincide with the acceleration of atherosclerosis in patients treated with ICIs. This \"accelerated\" atherosclerosis could be linked to inflammatory changes within the plaques, causing plaque destabilization or rupture. It is also unreasonable to rule out the possibility that the accelerated atherosclerosis is related to the development of vasculitis in these patients.",[25],"Vascular Complications",[27,28],"immune checkpoint inhibitors","cancer therapy","NOT_YET_RECRUITING","2026-06-08",{"date":32,"type":33},"2026-06-10","ACTUAL",{"date":35,"type":21},"2026-06-01",{"date":37,"type":21},"2031-06-01",{"name":39,"class":40},"University Hospital, Rouen","OTHER",1,{"id":43,"slug":44,"hasResults":11,"nctId":45,"briefTitle":46,"officialTitle":46,"acronym":4,"eligibilityCriteria":47,"healthyVolunteers":11,"sex":17,"minAge":4,"maxAge":48,"enrollmentInfo":49,"targetDuration":4,"studyType":51,"phases":52,"briefSummary":54,"conditions":55,"keywords":4,"overallStatus":29,"whyStopped":4,"lastUpdateSubmitDate":57,"lastUpdatePostDateStruct":58,"startDateStruct":60,"completionDateStruct":62,"leadSponsor":64,"locationsCount":41},"100630528","management-of-vascular-complications-in-pediatric-supracondylar-humerus-fractures-100630528","NCT07488845","Management of Vascular Complications in Pediatric Supracondylar Humerus Fractures","Inclusion Criteria:\n\n* ● Children Diagnosed with supracondylar humerus fracture (Gartland I-IV) aged under 15 years.\n\n  * Presented within 1st 48 hrs of injury.\n\nExclusion Criteria:\n\n* ● Old trauma \\>48 hours\n\n  * Previous vascular intervention in the same limb\n  * Another fracture in the same limb","15 Years",{"count":50,"type":21},50,"INTERVENTIONAL",[53],"NA","* To determine the incidence and types of vascular injuries associated with pediatric supracondylar humerus fractures.\n* Identify outcomes of different management strategies\n* Identify risk factors for vascular injury",[25,56],"Supracondylar Humerus Fracture","2026-03-19",{"date":59,"type":33},"2026-03-23",{"date":61,"type":21},"2026-04-01",{"date":63,"type":21},"2027-05-01",{"name":65,"class":40},"Assiut University",{"id":67,"slug":68,"hasResults":11,"nctId":69,"briefTitle":70,"officialTitle":70,"acronym":71,"eligibilityCriteria":72,"healthyVolunteers":73,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":74,"targetDuration":4,"studyType":51,"phases":76,"briefSummary":77,"conditions":78,"keywords":82,"overallStatus":90,"whyStopped":4,"lastUpdateSubmitDate":91,"lastUpdatePostDateStruct":92,"startDateStruct":94,"completionDateStruct":96,"leadSponsor":98,"locationsCount":41},"100382293","qualitative-and-quantitative-evaluation-of-vascular-flows-of-radial-ulnar-and-interdigital-arterial-trees-under-normal-and-pathological-conditions-by-3-tesla-mri-100382293","NCT04257747","Qualitative and Quantitative Evaluation of Vascular Flows of Radial, Ulnar and Interdigital Arterial Trees Under Normal and Pathological Conditions by 3 Tesla MRI","FLOWHAND","Inclusion Criteria:\n\n* Adult (≥ 18 years old)\n* patients who has received appropriate information and provided informed consent\n* patients benefiting from social security insurance\n* patients with no contraindications to magnetic resonance imaging\n* healthy volunteer or patient requiring radial forearm flap reconstruction or having received hand allotransplantation.\n\nExclusion Criteria:\n\n* Person with a contraindication to MRI\n* pregnant or breastfeeding woman\n* minors (\\\u003C 18 years)\n* person under guardianship or deprived of liberty by a judicial or administrative decision\n* person with upper limb arteriopathy with the exception of the hand transplant patients group.",true,{"count":75,"type":21},46,[53],"Allotransplants of vascularized composite tissues are subject to chronic vascular rejection, which can lead to graft loss.
