Va. Parfenov et Zs. Markova, VOLUMETRIC BLOOD-FLOW IN THE CAROTID ARTE RIES OF HEALTHY-SUBJECTS, Zurnal nevropatologii i psihiatrii im. S.S. Korsakova, 94(4), 1994, pp. 57-59
Using ultrasonic duplex scanning, volumetric blood flow (VBF) in the c
ommon carotid artery (CCA) was studied in 119 healthy subjects (73 mal
es and 46 females), aged 20-75. With age, mean linear flow rate seems
to undergo slowing down, while CCA diameter becomes wider. However, VB
F in CCA in the middle-aged and elderly subjects decreased insignifica
ntly. Males have larger CCA diameters and, consequently, greater VBF.
A correlation exists between head circumference measured horizontally
2 cm above the superciliary arches and CCA diameter. This explains hig
her VBF in CCA in subjects with greater head circumference.
