Background: During the last decade, cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) was a current research focus without a standardized classification in digital subtraction angiography (DSA). Angiographic cerebral vasospasm is defined as the narrowing of the dye column seen in major cerebral arteries that is often focal but could be diffuse. Although, cerebral vasospasm is considered a treatable clinicopathological entity, it is still responsible for many deaths and serious disabilities among patients suffering from intracranial aneurysm rupture [ 12 - 23 ]. The authors describe the case of a 13-year-old boy who presented with an intraventricular hemorrhage caused by a left trigonal arteriovenous malformation. Despite decades of research, cerebral vasospasm (CV) continues to account for high morbidity and mortality in patients who survive their initial aneurysmal subarachnoid hemorrhage. This narrowing depends mainly on the timeline of the SAH which is rarely pronounced before day 4 of the initial hemorrhage and reach the peak at day 7.

Increased blood flow, as opposed to pressure, may be more important. Assessment guidelines include indications for treatment, success rates for achieving treatment goals, and complication rates. Treatment for cerebral vasospasm includes injecting medication directly into the narrowed blood vessels. Current recommendation s for management of cerebral vasospasm and DCI after aneurysmal subarachnoid hemorrhage (aSAH) are as follows: Repeated cerebral injections may be required until the vasospasm settles. Cerebral vasospasm was defined as a reduction to less than 50% of the caliber of the cerebral artery on cerebral imaging. Posthemorrhagic cerebral vasospasm (PHCV) is a major cause of death and permanent disability in patients with aneurysmal subarachnoid hemorrhage (aSAH), which may account for almost 50 % of the deaths among those surviving in the initial ictus [1]. cerebral aneurysm radiology . The efficacy of tranexamic acid in treating melasma is more accurate, but the causes of melasma are more and more complicated, and there are actually differences in the efficacy of each patient for melasma, and the therapeutic effect and response of each patient's melasma for tranexamic acid are also different. The main endpoints triggering de-escalation of therapy are resolution of vasospasm or a significant established infarction in the territory at risk.
