Abstract
BACKGROUND: Cocaine and other vasoactive substances are known causes of cerebrovascular disease. Ictus during drug intake adversely affects outcome. MATERIALS AND METHODS: A retrospective review revealed 42 patients with cocaine abuse and stroke. Aneurysmal bleed occurred in 15 patients; the rest had stroke. The outcome of stroke because of cocaine intoxication was analyzed. RESULTS: Mean age for stroke was 38 (+/- 8.5 SD) years; males out-numbered females (20 : 7) similar to the pattern seen in subarachnoid hemorrhage (SAH) following aneurysm rupture. Nine had intracerebral hematomas, 6 had SAH with intracerebral hemorrhage (ICH)/ infarct, I had transverse myelopathy. Transient ischemic attack was identified in 4. Carotid occlusion was found in 2, and slow-flow in the vertebrobasilar system in 1. Fifteen were known hypertensives. Cocaine was the principal substance in all patients; 7 used other substances including marijuana and heroin. Three patients had HIV, 3 had hepatitis, 2 had syphilis, and 1 had tuberculosis. Urinalysis was positive for cocaine metabolites in 15; 2 had late analysis. Nine had ICH or SAH with poor neurological status at admission and died. Cocaine intoxication correlated with fatal cerebrovascular accident (CVA) (p < 0.001) and poor Glasgow Outcome Score (GOS) (p < 0.001). CONCLUSION: Stroke and cocaine use correlated with fatal CVA and poor outcome. Prompt diagnostic intervention may reveal the incidence of CNS injury with cocaine abuse.
