Clinical Analysis of Ruptured Aneurysms with Transcranial Doppler Ultrasonogrphy

Abstract
|
|
|
With the transcranial ultrasonic Doppler (TCD) technique described 1982 by Aasild et al, it is possible to record blood flow velocities in the basal arteries through the intact cranium.
The clinical material for study consists of 40 patients with ruptured aneurysms who were operated from March 1992 through June 1992.Sixteen individuals (Group A) were operated within 3 days, while the other 24 (Group B) had surgery between 4 and
11
days after subarachnoid hemorrhage (SAH). TCD was used to evaluate flow velocities within middle cerebral artery (MCA) at least every other day for one month. To prevent symptomatic vasospasm , Nimodipine was intravenously infused in doses of
2mg/hour
for 2 weeks in all patients. In the first 3 days post-SAH,no increased flow velocities suggestive of arterial narrowing or vasospasm were recorded. There was no significant difference in preoperative flow velocities between the groups but a
tendency of
early peak velocity in the Group A while late peak in the Group B.
