BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) is classically diagnosed based on the presence of severe thunderclap headache, focal neurologic symptoms, and the radiographic findings of reversible diffuse segmental cerebral vasoconstriction. We present a diagnostic test that may assist in the clinical diagnosis and facilitate treatment.
METHODS: From October 1, 2010, to August 1, 2013, we identified consecutive patients who presented with a presumptive diagnosis of RCVS and underwent cerebral diagnostic angiography with intra-arterial (IA) vasodilator therapy. Medical records including clinical presentation, radiographic, and angiographic images were all reviewed.
RESULTS: We identified a total of 7 patients (4 females; age range, 22-56; mean, 45 years) who met our inclusion criteria. Four patients received a combination of milrinone and nicardipine infusion either in the internal carotid arteries or in the left vertebral artery; the remaining patients received IA therapy solely with either nicardipine or milrinone. Five patients had a positive angiographic response, defined as significant improvement or resolution of the blood vessels irregularities. All 5 patients had a definite discharge diagnosis of RCVS. The remaining 2 patients had a negative angiographic response and based on their clinical and radiographic course had a final diagnosis of intracranial atherosclerotic disease.
CONCLUSIONS: Our small case series suggest that IA administration of vasodilators is safe and may aid in distinguishing vasodilator responsive syndromes such as RCVS from other causes. Further study is required with long-term clinical outcome to determine the utility of this diagnostic test.
