Abstract:
Introduction: Instability atlanto-axial junction is one of the
common causes of Cervicogenic headache in young adults.
In the formation of headaches, the leading role is played by
irritation of the vegetative plexus of the vertebral arteries.
Objective: Dopplerographic evaluation of blood flow
parameters in vertebral arteries in patients with instability of
the atlanto-axial junction.
Materials and methods: A retrospective analysis of the results
of Doppler ultrasound in the 2nd and 3rd segments of the
Vertebral Artery (VA) was performed in 36 patients aged 21-35
years, who had X-ray diagnosed instability of the atlanto-axial
junction; among the examined were 15 men and 21 women.
The maximum Systolic Velocity (Vs), the end Diastolic Velocity
(Vd), the Resistance Index (RI) in second and third segments of
VA in the neutral spine and flexion position of the neck. The
control group consisted of 27 people aged 19-34 years without
chronic headache, absence of arthrosis and instability of the
atlanto-axial junction according to the results of X-ray and MRI.
Dopplerography was conducted on a Philips HD 11XE device using
a linear and microconvection transducers in the frequency range
5-10MHz and 4-9 MHz; MRI - General Electric, Signa HDI, 1.5T.
Results: In the control group in the second segment of the
VA, Vs was 51.4±5.2cm/s, RI - 0.59±0.03; at the level of 3rd
segment-48.9±5.1cm/s, RI - 0.58±0.03; at the rotation of the
head - Vs 43.9±4.6 cm/s, RI - 0.62±0.03, respectively. In patients
with atlanto-axial instability at the level of C5-C6, Vs amounted
to 49.2±4.8cm/s, RI-0.61±0.03; at the level of 3-d segment of
VA-Vs was 47.2±4.5cm/s, RI - 0.60±0.03. When the head was
turned to the side in patients with instability of the atlanto-axial
junction, at the level of 3-d segment of VA-Vs was 34.1±4.2cm/s,
RI - 0.69±0.02 (P<0.05).
Conclusion: Instability of atlanto-axial junction is one of the
common causes of cervicogenic headache in young people. The
main pathogenetic mechanism of the onset of pain is changes
in blood flow in the third segment of the vertebral arteries,
especially during rotational movements.
