A preliminary study on the value of color Doppler ultrasound in evaluating the surgical efficacy of patients with tinnitus cerebri caused by bony compressive stenosis of the internal jugular vein
Objective To investigate the evaluation of surgical efficacy of cranial tinnitus with internal jugular vein(IJV)compressed by transversal process or styloid process of atlas with color doppler ultrasound(CDU).Methods The clinical data of 8 patients with cranial tinnitus due to IJV stenosis admitted to the Department of Neurosurgery,Beijing Shijitan Hospital,Capital Medical University from September 2020 to March 2023 were analyzed retrospectively.All patients with IJV stenosis due to compression of transversal process or styloid process of atlas were confirmed by computer tomography venography(CTV).After the surgery of partial decompression of the transversal process or styloid process of atlas,CDU examinations were performed 1 week before surgery,within 1 week after surgery,and 3-6 months after surgery to observe the changes of the maximum diameter,the mean flow volume(FVm)and the maximum velocity(Vmax)of the IJV.Results There was no statistical significance in the diameter or FVm of each part of IJV in 8 patients within 1 week after surgery(all P＞0.05).At 3-6 months post surgery,the maximum diameter of the IJV at J1 and J2 were increased significantly compared with before[J1:9.52±2.09 mm vs.7.45±2.10 mm,J2:6.75±1.74 mm vs.5.52±1.91 mm](both P＜0.05),whereas the difference in J3 was not significant(P＞0.05).The FVm of IJV was improved compared with before[J1:349.20±188.99 ml/min vs.204.60±118.50 ml/min,J2:193.10±91.32 ml/min vs.124.50±81.57 ml/min,J3:152.70±95.71 ml/min vs.61.90±53.23 ml/min)(all P＜0.05).There was no statistical significance in the parameter of Vmax of IJV compared with before(P＞0.05).Conclusions For patients of cranial tinnitus caused by IJV stenosis compressed by bone structure,the preliminary observation has indicated that the surgery of partial decompression of the transversal process or styloid process of atlas may improve the lumen and hemodynamics of the narrow part of IJV.CDU can be used as an objective method to evaluate the effect of surgical treatment of IJV stenosis compressed by bone structure.
