The Dissections of Craniocervical Arteries

Dissection of cranincerviccal arteries internal, carotid artery (ICA), or vertebral artery (VA) is an increasingly recognized entity and infrequent cause of stroke. We investigated 8 patients (4 women and 4 men) with dissections of the craniocervical arteries. artd 4 nzert.) (L'itlL di.5~.sectiorr.s of tlLe craniocerUical arteries. Diagnostic procedures for detection of craniocervical dissection included: extracranial ultrasound-color Doppler flow imaging (CDFI) of carotid and vertebral arteries, transcranial Doppler sonography (TCD) and radiological computer tomography (CT) and digital subtractive angiography (DSA) examinations. Ultrasound findings (CDFI of carotid and vertebral arteries) were positive for vessel dissection in seven patients (or 87.5 per cent) and negative in one patient.DSA was consistent with dissection in five patients (or 62.5 per cent), negative in one, while in two patients the examination was not performed due to known alergy to contrast media. Five patients (62.5 per cent) were treated with anticoagulants, one with supressors of platelet aggregation, and two patients were operated. Six patients (75 per cent) after the treatement showed partial recovery of neurological defects, and an improvement of ultrasound finding of dissected arteries. In one patient, following operation, stroke developed with deterioration of motor deficit, and one patient was readmitted three rnonths later due to newly developed stroke and soon died. Tlte diagnosis should be suspected in any young or middle-aged patient with new onset of otherwise unexplained unremitted headache or neck ache, especially in association with transient or permanent focal neurological deficits.
