Symptomatic cerebral vasospasm in the setting of carmustine wafer placement for glioblastoma: A case presentation and review of literature.

BACKGROUND: Gliadel placement in glioblastoma resection, particularly with concurrent chemoradiation, has demonstrated an improvement in survival. There have been several reported adverse effects, some of which lend to significantly increased morbidity and mortality. With only two other cases described in literature, cerebral vasospasm secondary to carmustine-impregnated wafers is an extremely rare side effect. CASE DESCRIPTION: We report the case of a 51-year-old female who presented with the left lower limb paresis 8 days after high-grade glioma resection provoked by carmustine wafer placement. CONCLUSION: We urge surgeons to reconsider placement of carmustine wafers in nations where the surgical resection cavity includes exposed large cerebral vasculature. We also propose the early identification of this devastating complication in the postoperative period by maintaining a high clinical suspicion and prompt utilization of computed tomography and digital subtraction angiography in the management and treatment of these patients accordingly.
