Abstract

Doppler ultrasonography (US) is a noninvasive radiological examination.In this study, carotid and vertebral artery (VA) Doppler US and magneticresonance (MR) angiography findings in vertigo cases were reviewed.Methods: Doppler US and MR angiography results of vertigo patients admittedbetween October 2011 and June 2012 were analyzed retrospectively.The age and sex of the patients, atherosclerotic changes in vessels,diameter of VA, and flow volume of VA were recorded. Sensitivity, specificity,positive predictive value, negative predictive value, LR+ values of MRangiography and Doppler US results were calculated.Results: A total of 403 cases included 135 (33.5%) women (age: 54.79±14.1years), and 268 (66.5%) males (age: 57.81±15.54 years). Atheroscleroticchange rates of right-left carotid arteries and the mean diameter of theright VA of women were significantly lower as compared to men (p=0.03),(p=0.0001), (p=0.009). Stenosis of the right common carotid arteries wereas follows: in 1 (0.2%) case, less than 50%; in 1 (0.2%) case between 50-60%;and in 3 (0.7%) cases between 60-70%. Stenosis of left common carotidarteries were detected in 3 (0.7%) cases as less than 50%, in 1 (0.2%) caseas 50-60%, in 4 (1%) cases as 60-70%, and in 2 (5%) cases more than 70%,and total occlusion was detected in 2 (5%) cases. Total occlusion (100%)was present in 1 (0.2%) case. Atherosclerotic change rates were significantly(p=0.0001) higher in patients over 45 years old. There was an approximately2 fold likelihood ratio (LR (+) = 2.03) between Doppler US findingsand MR angiography findings in vertigo cases.Conclusion: Doppler US is often referred to neurology practice, as being apractical, rapid, inexpensive, reliable, and noninvasive imaging techniqueaccording to MR angiography. It can be chosen to give information aboutthe morphological and hemodynamic structure of the vertebrobasillar systemin the early period of vertigo, especially in elderly patients.

Özet

Doppler ultrasonografi (US), sıklıkla başvurulan noninvazif bir radyolojik incelemedir. Bu çalışmada vertigo olgularının bilateral karotis ve vertebral arter (VA) Doppler US ve manyetik rezonans (MR) anjiografi bulguları incelendi. Yöntemler: Ekim 2011-Haziran 2012 arasında baş dönmesi şikayeti ile başvuran olguların Doppler US ve MR anjiografi sonuçları retrospektif olarak incelendi. Hastaların cinsi, yaşı, aterosklerotik değişiklikleri, VA (mm) ve akım volümleri (mL/dk) kaydedildi. Doppler US ile MR anjiografi sonuç- larının duyarlılık, özgüllük, pozitif kestirim değeri, negatif kestirim değeri, LR+ değerleri hesaplandı. Bulgular: Toplam 403 olgunun %33,5'i (n=135) kadın (yaş: 54,7±14,1 yıl), %66,5'i (n=268) erkekti (yaş: 57,8±15,5 yıl). Kadınlarda sağ-sol karotis arterlerin aterosklerotik değişiklik oranları ve sağ VA damar çap ortalamaları erkeklere oranla istatistiksel olarak anlamlı derecede düşüktü (p=0,03), (p=0,0001), (p=0,009). Sağ karotis arterde 1 (%0,2) olguda %50'nin altında, 1 (%0,2) olguda %50-60 darlık, 3 (%0,7) olguda %60-70 darlık saptandı. Sol karotis arterde 3 (%0,7) olguda %50'nin altında, 1 (%0,2) olguda %50-60 darlık, 4 (%1) olguda %60-70 darlık, 2 (%5) olguda %70 üzeri darlık ve 2 (%5) olguda %100 (tam) oklüzyon saptandı. Bir olguda (%0,2) sol VA %100 (tam) oklüde bulundu. Kırk beş yaş üstü olgularda aterosklerotik değişiklik varlığı anlamlı derecede yüksekti (p=0,0001). Doppler US ve MR anjiografi sonuçları karşılaştırıldığında Doppler US patoloji saptanan hastaların MR anjiografilerinde de patolojik olma riskinin yaklaşık 2 kat fazla olduğu gö- rüldü (LR (+)=2,03). Sonuç: Doppler US, MR anjiografiye göre kolay uygulanabilen, hızlı, ucuz, güvenilir ve noninvazif bir görüntüleme yöntemidir. Özellikle ileri yaş vertigo olgularında vertebrobaziler sistemin morfolojik ve hemodinamik yapısı hakkında erken dönemde bize yol göstermesi nedeniyle tercih edilmelidir.
