Abstract

Objective. The research is aiming at developing criteria to assessing the effectiveness of vertebral artery reconstructive surgery in vertebrobasilar insufficiency (VBI) patients.

Material and methods. The article contains the results of ultrasound duplex research on blood flow and vertebral artery (VA) responsiveness in 194 VBI patients before and after various reconstructive surgeries on VA segment 1 pathology. The obtained results were compared with similar research data in 20 non-patient volunteers. The research suggests a method to assess blood flow deficit on vertebral arteries and VA responsiveness that stipulates the measurement of the total blood flow on VA and responsiveness index determination in VA segment 3 in breath-holding test.

Results. It was found out that in both healthy patients and operated on VBI patients threshold value of the total volumetric blood flow in VA makes up 250 mL/min. In patients showing increased post surgery blood flow exceeding this value VBI symptoms are leveled or their sufficient regress is observed (р<0.05). The detected value of the responsiveness index 0,3 (30%) proved to be significant (р<0.05) both in non-patient volunteers and in patients showing VA segment 1 post surgery clinical improvement.

Conclusion. The developed criteria of the total blood flow and responsiveness index in VBI patients are positive indications for VA segment 1 reconstructive surgery.
