Normalization of Transcranial Doppler Middle Cerebral Artery Velocities after Aneurysm Clipping

Abstract

BACKGROUND: Factors that Promote Normalization of Middle Cerebral Artery (MCA) Velocities after Cerebral Aneurysm Surgery May Be Important to Identify in Order to Optimize Management. Survival Analysis of Serial Transcranial Doppler (TCD) MCA Velocities in the Setting of Aneurysm Surgery Offers an Additional Means of Analyzing Outcome. METHODS: We Retrospectively Studied Serial MCA Velocities Obtained Via TCD in 113 Patients Who Underwent Cerebral Aneurysm Clipping to Analyze Which Factors Promoted Normalization. the Presence of Bleeding, Aneurysm Location, Age, Gender, Ethnicity, Initial Blood Pressure, Hemoglobin, and Clinical Condition Were Examined. RESULTS: Patients Who Did Not Bleed But Were Clipped Still Tended to Have Transient Periods of Abnormally Elevated Velocities. of Those Patients Who Bled and Were Clipped, Older Patients Normalized Faster. Women Showed a Trend toward Slower Normalization Only in the Subarachnoid Hemorrhage (SAH) Absent Group. Other Parameters Listed above Did Not Effect Normalization Time. CONCLUSIONS: Our Data Suggest Aneurysm Surgery in and of itself May Promote Transient Rises in MCA Velocities. Age Appears to Be a Significant Factor in Predicting Normalization of MCA Velocities after SAH.
