Sažetak
Craniocewical artery disscction (CCAD) is primarily diagnosed by angiography, brain magnetic resonance (MR) or MR angiography. Color Dopplcr flow imaging (CDFI) has been underrated duc to the localization of dissection, which appears to be most commonly localized intracranially. Nevertheless, dissection may manifest in various ways, enabling CDFI to present a broad spectrum of findings.The aim of this studvwas to analyze ultrasonographic findings in paricnts with clinical or ultrasonographic presentation of CCAD. Forty-three patients who presented with CCAD over a two-year period were retrospetively analyzed. Twenty-three of these paticnts showed clinical manifestations of CCAD, whereas in 19 patiencs ultrasound revealed double lumen or bifurcation stenosis with double lumen. Carotid and vertebral CDFI was performed on an Acuson 1Z8 XP device. Color and pow-er Doppler scans and hemodynamic spectra were analyzed. Data are presented descriptively. Data on 43 paticnts (28 male.and 15 female, mean age 59&plusmn ; 11 years) were analyzed. There were 49 ultrasonographically detected dissceted vessels (37 carotid, 10 vertebral and 2 subclavian arteries). A string sign was found in 5 patients (5 internal carotid arteries (ICA)), string and pearl sign in 2 patients (1 ICA and 1 vertebral artery (VA)), subintimal flow in one patient (1 , double lumen in 12 patients (3 common carotid arteries (CCA), 7 ICA, 3 VA and 2 subclavian arteries) ; one paticnt presented as VA dissection and subarachnoid hemorrhage (SalH ; ICA dissection on ultrasonography) ; carotid stenosis with double lumen under the plaque basc was found in 17 patients (2 ACC, 13 bifurcation stenoses, and 2 ICA stenoses with dissection under the plaque base) ; hemodynamic spectra suggesting distal occlusion were detected in 8 patients (3 ICA, 6 VA) ; and multiple vessel involvement was present in 7 (16%) patients. Ultrasound can show a broad spectrum of findings in CCAD including direct evidence for intimal flap and detectable subintimal flow as well as signs of hemodynamically signiocant flow obstruction.
