[Instantaneous measurement of blood flow velocity in internal carotid arteries by pulsed Doppler in cerebral arteriovenous malformations].
Hemodynamics (systolic rate: VS and diastolic rate: VD) of internal carotid artery blood flow was determined by pulsed Doppler combined with ultrasound scans to measure instantaneous flow rate in 8 patients with cerebral arteriovenous malformations. Values obtained were compared with those in 10 healthy volunteers. Measurement of the diastolic fraction a = (formula: see text) appears to be a valid method for assessing severity of this malformation and the importance of its output. Repeated tests in one patients operated upon by several stages demonstrated the importance of a blood shunt after ablation of lesions.
