Background: We reported that transverse cervical artery had various forms in the cadaver. The purpose of this study was to examine patients with neck and shoulder pain from vascular resistance of the transverse cervical artery. Methods: The subjects consisted of 54 patients with neck and shoulder pain (group P) and 20 normal volunteers (group N). They were all females, and their mean age was 67.2 in group P and 70.4 in group N. Firstly isometric exercise around the neck and back was performed on all subjects in the sitting position. Patients were only asked whether the pain had changed before and after exercise. The transverse cervical artery was identified by color doppler ultrasonography, and pulsatility index (PI) was measured by pulsed doppler imaging. PI was compared between group P and group N, and was compared with the effects of exercise in group P. Results: After exercise, the pain was the same in 16 patients, improved partially in 27 patients and disappeared in 11 patients. PI of the deep branch in the group P was significantly larger than that in group N. PI of the deep branch in the 11 patients whose pain disappeared, tended to be smaller than that of the other patients. Conclusion: We suppose that high vascular resistance of the deep branch of the transverse cervical artery is a characteristic seen widely in patients with neck and shoulder pain.
