Abstract Disclosure: J. Beckhaus: None. S. Boekhoff: None. B. Bison: None. C. Friedrich: None. H.L. Muller: None. Craniopharyngiomas are rare, embryonic, malformational tumors of the (supra-)sellar region. Due to tumor and/or treatment-related hypothalamic lesions, patients develop morbid obesity. Obesity is a major vascular risk factor, leading to reduced 20-year overall survival and a 3- to 19-fold higher cardiovascular mortality after craniopharyngioma compared to the general population. An analysis within the Childhood Cancer Survivor Study (CCSS) revelaed a 10-fold higher relative risk for stroke in adult survivors of childhood/young adult cancers compared to their siblings. To study craniopharyngioma-specific risk factors for vascular damages we searched three databases (Pubmed, CINAHL and Web of Science) and included 49 articles after title and abstract screening. Eligible studies were case reports, cohort and cross-sectional studies. Neurovascular damages due to surgical interventions included cerebral infarcts, stroke, aneurysms, anterior/middle cerebral artery syndrome (ACA/MCA), cerebral venous sinus thrombosis, and seizures. Radiation-induced vascular disease described Moyamoya syndrome, radionecrosis and thrombosis. Tumor-induced inflammation is suspected to play a causal role in the etiology of vascular complications in proximity of the tumor. Therefore, early diagnostics such as echocradiography or cardial MRI and risk-adapted prevention and treatment options for vascular disease are needed to improve long-term prognosis after craniopharyngioma treatment. This review summarizes the available evidence for vascular disease after pediatric- and adult-onset craniopharyngioma to derive possible treatment pathways. Individualized, tertiary prevention programs are required for craniopharyngioma patients and survivors to overcome or reduce the risk of vascular complications and elevate their quality of survival.
