Color Doppler patterns of craniocervical artery dissection-diagnosis and monitoring

Color Doppler patterns of craniocervical artery dissection-Diagnosis and Monitoring Lovrenćić Huzian A, Zavoreo I, Vuković V, Kesić MJ, Demarin V. Background: The localization of craniocervical dissection determines symptomatology. Besides headache, st~oke. cranial nerve paralysis. patients may present with other clinical symptoms. . Methods: Color Doppler Flow Ima9ing was applied in a variety of neurological clinical settings as a result of craniocervical artery disseGion. The symptoms varied from fluctuating lower limb paraplegia. left arm fluctuating paresis, unexplained loss of consciousness up to usual clinical presentalions of dissections tike headache, stroke and cranial nerve palsies. Results: Dissections arising from aortic arch'presented with different symptoms depending of its localization. In patients with headache, w strvke. usual site of Ihe dissection was the distal partion of the intemal camtid or vertebral artery. While in the first group of patients Color Doppler enabled visualisation of the double lumen, with no changes dudng time. in the second group color Doppler enabled visualisation of the hemathoma, kx.alization of the oalusion, redistribution of the hemodynamic and acCrvation of the collateral pathways. During time, in Ihis gmup the regression of the hemathoma was visible. Conclusions: Craniocervical artery color Poppler is a noninvasive tool, enabling easy. noninvasive, bedside evaluation of the stroke patients and of the patients with other Ginical
