Decreased Vertebral Artery Haemodynamics in Patients with Loss of Cervical Lordosis

Published: Med Sci Monit. 2016 Feb 15;22:495-500. Referenced in Pub Med: https://www.ncbi.nlm.nih.gov/pubmed/26876295

Authors: Bulut MD, Alpayci M, Şenköy E, Bora A, Yazmalar L, Yavuz A1, Gülşen İ.

BACKGROUND: Because loss of cervical lordosis leads to disrupted biomechanics, the natural lordotic curvature is considered to be an ideal posture for the cervical spine. The vertebral arteries proceed in the transverse foramen of each cervical vertebra.

 

CONCLUSIONS: The present study revealed a significant association between loss of cervical lordosis and decreased vertebral artery hemodynamics, including diameter, flow volume, and peak systolic velocity.

Increase in Cerebral Blood Flow indicated by increased Cerebral Arterial area and pixel intensity on brain magnetic resonance angiogram following correction of Cervical Lordosis.

PUBLISHED: Brain Circ. 2019 Jan-Mar;5(1):19-26. doi: 10.4103/bc.bc_25_18. Epub 2019 Mar 27. Pub Med: https://www.ncbi.nlm.nih.gov/pubmed/31001596

AUTHORS: Katz EA1, Katz SB1, Fedorchuk CA2, Lightstone DF2, Banach CJ1, Podoll JD3.

RESULTS: Pixel intensity increased 23.0%-225.9%, and a Student’s t-test determined that the increase was significant (P < 0.001). Regression analysis of the change in pixel intensity versus the cervical lordosis showed that as the deviation from a normal cervical lordosis increases, percentage change in pixel intensity on MRA decreases.

CONCLUSION: These results indicate that correction of cervical lordosis may be associated with an immediate increase in cerebral blood flow.
