Abstract:

Clinical features and therapeutic strategies of cervicocranial arterial dissection (CCAD) are still unclear. A retrospective review was conducted on 71 CCAD patients. Diagnosed by DSA and outcome evaluation was through mRS scores follow-up 12 months. All patients were allocated into three groups according to clinical situation: 1) subarachnoid hemorrhage (SAH), 2) ischemic symptoms and 3) mass effect. CCAD with anterior circulation arterial dissection (ACAD) had higher ischemia than that with posterior circulation arterial dissection (PCAD) (p=0.023). The non-aneurysmal dissection (NAD) patients were susceptible to ischemia (p=0.00) and patients with aneurismal dissection (AD) were more susceptible to SAH (p=0.001); The outcome of patients with SAH was significantly worse than patients with other manifestations (p=0.012). Following up one year, the outcome of CCAD involving posterior inferior cerebellar artery (PICA) was significantly worse than the other area (p=0.035). There was no statistically significant difference in mRS scores between endovascular treatment and conservative treatment (p=0.052) at one year follow-up. Patients suffering from SAH that received endovascular treatment experienced improved outcomes than patients with conservative treatment (p=0.033). The patients in the ACAD, NAD and extracranial CCAD groups were more likely to suffer from ischemia, while patients in the AD group were susceptible to SAH. CCAD with SAH or involving PICA had poor prognoses. The therapeutic efficacy of conservative treatment is nearly equal to endovascular treatment in CCAD patients follow up 12 months; however, endovascular treatment may decrease the risk of mortality for the patient with SAH.
