While many studies suggest a correlation between higher hemorrhage risk and the concurrent presence of AVM and aneurysms, few authors have focused specifically on flow-related aneurysms alone. In many instances, the source of rupture is also unclear. Meta-analysis from 2016 suggested that 49.2% of hemorrhages were secondary to aneurysm rupture, 45% from AVM rupture, and 5.7% were undetermined.In a study of 302 patients, of which 52.6% had a hemorrhagic presentation, demonstrated a significant increase in rate of hemorrhage in those with flow-related aneurysms. Thus, it is necessary to figure out risk factors related to ruptured flow-related aneurysms in pAVM.",[24,25,26,27],"Arteriovenous Malformation of Central Nervous System","Aneurysm, Ruptured","Aneurysmatic Subarachnoid Haemorrhage","Aneurysm Cerebral",[29,30,31,32],"arteriovenous malformation","flow-related aneurysm","ruptured aneurysm","subarachnoid hemorrhage","RECRUITING","2025-06-25",{"date":36,"type":37},"2025-07-03","ACTUAL",{"date":39,"type":37},"2025-06-13",{"date":41,"type":20},"2026-12-31",{"name":43,"class":44},"The First Affiliated Hospital with Nanjing Medical University","OTHER",2]
