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.",[62,63,64,65],"Arteriovenous Malformation of Central Nervous System","Aneurysm, Ruptured","Aneurysmatic Subarachnoid Haemorrhage","Aneurysm Cerebral",[67,68,69,70],"arteriovenous malformation","flow-related aneurysm","ruptured aneurysm","subarachnoid hemorrhage","2025-06-25",{"date":73,"type":74},"2025-07-03","ACTUAL",{"date":76,"type":74},"2025-06-13",{"date":78,"type":58},"2026-12-31",{"name":5,"class":6},2]
