目的探讨后循环缺血患者中磁共振血管造影(MRA)基底动脉不显影的临床特点和神经影像特点与预后的关系。方法回顾性分析MRA上基底动脉不显影的18例后循环缺血患者的临床资料、影像学所见以及临床结局。男11例,女7例,年龄43~80岁,平均64.8岁。结果 18例患者中,高血压病14例(77.8%),脑梗死13例(72.2%),心脏病9例(50.0%)。入院时:NIHSS评分(12.11±6.92)分,GCS评分(9.44±4.80)分,其中10例呈昏迷状态(GCS评分≤8分),梗死评分(3.75±1.38)分。18例患者MRA上基底动脉和双侧椎动脉颅内段几乎不显影。出院时:结局较好者2例(11.1%);结局不良者16例(88.9%),其中住院期间死亡6例(1/3患者死亡)。结论 MRA基底动脉不显影的后循环缺血患者,系后循环多个血管支配区梗死,预后很差。
Objective To investigate the clinical features of non-developing basilar artery in magnetic resonance angiography (MRA) in patients with posterior circulation ischemia and the relationship between the characteristics of neuroimaging and prognosis. Methods The clinical data, imaging findings and clinical outcomes of 18 patients with posterior circulation ischemia on basilar artery without MRA were retrospectively analyzed. 11 males and 7 females, aged 43 to 80 years, an average of 64.8 years old. Results Of the 18 patients, 14 were hypertension (77.8%), 13 were cerebral infarction (72.2%) and 9 were heart disease (50.0%). On admission, NIHSS score (12.11 ± 6.92) and GCS score (9.44 ± 4.80), of which 10 were unconscious (GCS score ≤8) and infarct score (3.75 ± 1.38). In 18 patients, the intracranial segments of basilar artery and bilateral vertebral arteries in MRA were almost not developed. At discharge: 2 patients (11.1%) had better outcomes; 16 patients (88.9%) had poor outcomes, of which 6 were hospitalized (1/3 of patients died). Conclusions Patients with posterior circulation ischemia with non-visualized basilar artery of MRA have multiple infarcts in the posterior circulation with poor prognosis.
