Abstract:
Objective To investigate the hemodynamic features of left innominate vein （LIV） compression and their association with clinical manifestations， and to assess the diagnostic value of ultrasound. Methods A total of 32 patients with LIV compression and 67 healthy controls （HCs） were enrolled， and according to the symmetry of the diameters of bilateral transverse sinuses， sigmoid sinuses， and internal jugular veins （IJV）， the HCs were divided into symmetric group with 32 individuals and asymmetric group with 35 individuals. All subjects underwent CTV/MRV and ultrasound examination to measure the diameter， velocity， and flow volume of IJV and vertebral vein， and the differences between groups were analyzed. The receiver operating characteristic （ROC） curve was plotted to assess diagnostic efficacy. Results The patients with LIV compression mainly had the neurological symptoms such as cerebral tinnitus， dizziness， and tinnitus. Compared with the HCs， the patients with LIV compression had a significantly lower total flow volume of IJV and vertebral vein on the ipsilateral side [（406.42±177.05）ml/min vs （742.55±276.41）ml/min， P0.001）]， and the parameters of the ipsilateral side were lower than those of the contralateral side. There was no significant difference in the flow volume of IJV between the contralateral side of patients with LIV compression and the dominant side of the HCs in the asymmetric group. Total flow volume had an area under the ROC curve of 0.849 in predicting LIV compression， with a sensitivity of 77.60%， a specificity of 78.10%， and a cut-off value of 525.73 ml/min. Conclusion This study systematically reveals the blood flow characteristics of the bilateral IJV-vertebral vein system in patients with LIV compression，i.e.，LIV compression leads to a reduction in flow on the ipsilateral side and a compensatory increase on the contralateral side，and the asymmetry of bilateral blood flow may be the cause of the symptoms such as cerebral tinnitus and tinnitus.Ultrasound can be used to measure the total flow volume of IJV and vertebral vein， and it can effectively identify this disease and thus has a good value in screening.
