Hematologic Predictors of Endovascular Retreatment for Recurrent Vasospasm in Aneurysmal Subarachnoid Hemorrhage

Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) is associated with a high degree of morbidity and mortality and is well established as a predictor of poor functional outcome, Endovascular interventions involving intra-arterial infusion of vasoactive agents or balloon angioplasty are frequently employed in the management of symptomatic cerebral vasospasm following aSAH. Many of these patients suffer from recurrent vasospasm and often require multiple endovascular treatments; however, there have been very few investigations to assess predictors of retreatment and they have produced inconsistent results.
