Digital subtraction angiography findings of stroke in young adult population: a multi-center record-based study

Abstract

BackgroundStroke is one of the main causes of disability, in which nearly 2/3 of survivors experience disability and interferes with the patient’s daily functional activities. Hypertension, dyslipidemia, obesity, and smoking habits are the main causes of stroke in young adults. Vascular abnormalities are also risk factor for stroke in young adults. Advanced imaging examinations such as cerebral digital subtraction angiography (DSA) can provide a clear picture of the vasculature of the blood vessels of the human brain and provide a real-time picture of the hemodynamic status, blood flow and collateral circulation of the cerebral vessels.ResultsThere were approximately 999 patients who had DSA cerebral examination during the study period. The total young adult population was 147 [92 males (62.4%) and 55 females (37.6%)]. There were 82 patients with ischemic stroke (60.7%). The main etiology of ischemic stroke in this study was intracranial atherosclerotic disease (ICAD) [44 (53.65%)]. The young adult population had 53 hemorrhagic stroke patients (39.3%). The main cause of hemorrhagic stroke is hypertensive vasculopathy (41.5%), followed by a ruptured cerebral arteriovenous malformation (CAVM) (37.7%). There were 12 patients with cerebral sinus venous thrombosis (CSVT). Headache is the main complaint of patients with venous stroke, followed by seizures and hemiparesis. The transverse sinus is the most common site for occlusion (66.7%).ConclusionThis study describes the characteristics and prevalence of stroke in young adults based on the results of cerebral DSA examination. Stroke in young adults is not uncommon. Several traditional risk factors in old age are now found in young people. Lifestyle modification is needed to reduce the prevalence of stroke in young adults.
