The frequencies of radiological features detected in patients with ICAD and VAD also differed.Ĭraniocervical artery dissection (CAD) refers to a tear in the artery lining, resulting in an intramural hematoma toward the intima or the adventitia of the internal carotid artery or vertebral artery. The distributions of cervical and intracranial artery dissections were different between ICAD and VAD. 1.79%, p = 0.029) were more frequently observed in ICAD than in VAD, and dissecting aneurysms were less frequent (13.10% vs. In contrast, dissections of VAD were more common in the intracranial artery (55.36% vs. Dissections of ICAD were more frequently at the extracranial portions of the artery compared with those of VAD (70.24% vs. The frequency of hypertension, diabetes, smoking, drinking, and cervical trauma did not differ between ICAD and VAD. Patients with ICAD were more likely to be men compared with VAD (85.71% vs. The mean age of patients in the ICAD and VAD groups was 43.37 ± 14.01 and 41.00 ± 12.98 years old, respectively. ResultsĪ total of 140 patients with cervicocerebral artery dissection were included in the study, including 84 patients in the ICAD group and 56 in the VAD group. Baseline characteristics, predisposing factors, and radiological features of ICAD versus VAD were compared.
MethodsĪll cases diagnosed with cervicocerebral artery dissection, ICAD, or VAD were identified through a medical records database, between January 2010 and January 2020.
We conducted a study to investigate the predisposing factors and radiological features in patients with ICAD or VAD. However, very few studies have compared the differential features between internal carotid artery dissection (ICAD) and vertebral artery dissection (VAD), including both cervical and intracranial artery dissections. Cervicocerebral artery dissection is an important cause of ischemic stroke in young and middle-aged individuals.
