AIM: This study was aimed at recording, by means of a transcranial Doppler (TCD) device, the values of blood flow velocities (BFV) in the middle cerebral artery (MCA) in physiological conditions, in a population of healthy women in various ages of their life, in order to establish normative data in an Italian female population. METHODS: Our sample consisted of 100 healthy women (mean age 38 +/-15.14 years, range 12-78) that underwent an investigation of the intracranial circulation by means of TCD. Patients were subdivided into 4 age groups: less than 20 years; 20-34 years; 35-50 years; more than 50 years. RESULTS: No statistically significant differences were present between the mean BFV in the left and right MCAs of the subjects considered as a unique population (left MCA 68.06+/-9.22 cm/s; right MCA 66.71+/-8.79 cm/s). The BFVs tended to significantly decrease with the increasing of age. In fact, they were so distributed: left MCA 82.55+/-6.85 cm/s and right MCA 80.27+/-4.13 cm/s in the younger group; left MCA 72.15+/-6.37 cm/s and right MCA 70.68+/-6.79 cm/s in women aged 20-34; left MCA 63.85+/-7.08 cm/s and right MCA 63.06+/-7.29 cm/s in women aged 35-50; left MCA 60.67+/-6.85 cm/s and right MCA 59.10+/-5.36 cm/s in the last group. CONCLUSIONS: The present study defined a normal age-related range of variations in MCA BFVs, useful for future comparisons in studies involving pathological female subjects.
