Vascular Morbidity and Mortality in Craniopharyngioma Patients-A Scoping Review

Craniopharyngioma (CP) treatment, including surgery and radiotherapy, can have short- and long-term vascular side effects. Hypothalamic damage is related to morbid obesity and may increase the lifelong risk of experiencing vascular events in CP patients. This review summarized the available evidence regarding vascular complications in adamantinomatous or papillary CP patients, whatever their age at diagnosis. Three databases (Medline, CINAHL, Web of Science) were searched (06/2023) to retrieve eligible articles. The search was limited to peer-reviewed articles. Titles, abstracts, and full texts were screened by two independent reviewers, and data were extracted using a self-developed grid. Seventy-two studies were included in this review; the majority were case reports. Reported vascular sequela that occurred due to surgery were fusiform dilation of the carotid artery, stroke, vasospasm, hemorrhage, and aneurysm. Related conditions that emerged due to radiotherapy included Moyamoya syndrome and cavernoma. Cardiovascular morbidity and mortality often lead to hypothalamic obesity and metabolic syndrome in CP patients. Vascular damage is a rare complication of CP treatment. Surgical strategies should protect the surrounding hypothalamic and vascular structures. Patients receiving radiotherapy, particularly at a young age, should undergo magnetic resonance angiography monitoring to identify possible neurovascular sequela during post-treatment care.
