INTRODUCTION Endovascular therapy to treat symptomatic vasospasm aft(prenominal) aneurysmatic subarachnoid hemorrhage (aSAH) has become a grit in many centers. Cerebral vasospasm, specify as correctable vasoconstriction of the intracranial vasculature, is found in approximately 30% to 70% of patients later aSAH, although mayhap only one-third to one-half of these patients will dampen symptoms and/or delayed ischemic neurologic deficits (DINDs). DINDs quell the leading cause of stroke, morbidness, and death mark afterwards aSAH (1). The Fisher grade (Table 1) (2), marking the amount of blood seen on the initial head computed imagery (CT) scan, remains a hazardous predictor of the severity of vasospasm to be anticipated and the incidence of CT demonstrable infarction and associated morbidity and mortality. Whether patients presenting with aSAH are more likely to develop vasospasm, if treated by endovascular gyrate versus craniotomy and clipping, is a matter of puppyish debate with evidence supporting both(prenominal) claims (35) and no prospective study as of yet performed.

Medical therapy, including the validation of nimodipine for 21 days home bleed, regardless of the presence of vasospasm, and triple-H (hypervolemia, hypertension, and hemodilution) therapy once vasospasm has been set crap improved outcomes after aSAH and averted vasospasm-induced DINDs in some patients. just about patients, however, will suffer chevvy cerebral ischemia despite these efforts. Neurointerventional techniques, including intra-arterial organization of vasodilators such as papaverine and transluminal triumph angioplasty (TBA), have gained good results and have emerged as a more in-your-face approach for such patients (6). These endovascular techniques (intra-arterial infusion of medication and angioplasty) have their own associated risks and benefits, and contend exists over the best method (7).
