[Surgical treatment of deformities of the extracranial division of the vertebral artery].
Bends and twisting are encountered most frequently in the first segment of the vertebral artery (VA), annular and spiral torsions are rare findings. In insufficiency of circulation in the vertebrobasilar channel, operation is indicated in VA bends at an angle of no less than 90 degrees and twisting and torsion with the arc radius of 5 mm and less. Surgery includes removal of the fibrous strands, arteriolysis, desympathization, scalenotomy, and immobilization of the artery in a cuff of muscular or fat tissue. As the result of surgery the deformities may be corrected completely or changed to elongations with the arc radius measuring 10 mm and more. Operative interventions were performed for deformity of the first VA segment on 25 patients with good immediate and late results.
