Abstract
Background and purposeThe symptom of headache and neck pain is common in patients with cervicocerebral artery dissection (CAD). We attempt to screen ischemic stroke patients with CAD based on the characteristics of the pain. MethodsEighty-one consecutive ischemic stroke patients with CAD from 2010 to 2017 and 84 consecutive ischemic stroke patients with large artery atherosclerosis (LAA) were registered prospectively and observed in Zhengzhou, China. Those ischemic stroke patients complained of headache and neck pain were categorized into 2 groups. By analyzing the difference of headache and neck pain in 2 groups, we summarized characteristics of the pain secondary to CAD. ResultsThere were 34 patients in CAD group and 19 patients in LAA group. As for patients in CAD group, the pain could be located in the ipsilateral (41.9%), bilateral (41.9%), or contralateral (16.1%) side of the dissected artery, but in LAA group the pain was often in both sides (68.4%). When the dissected artery was involved in anterior circulation, 55.6% of CAD patients had pain in temporal and when involved in posterior circulation, 65.2% of CAD patients had pain in the occipital and neck. Patients with CAD had a higher prevalence of throbbing pain (30.0%), while pulsating pain (43.8%) was more common in LAA group. Patients often presented with severe pain (46.9%) in CAD group, while less frequently (11.8%) in LAA group, with a significant difference (P = .003). And there was a significant difference between the length (≥20 mm) of the involved artery and severity of the pain (P = .028) in CAD group. ConclusionsIschemic stroke patients caused by CAD tend to suffer from headache and neck pain, which may be severe and throbbing, compared with those resulting from LAA. The anterior circulation dissection has a higher prevalence of temporal pain while posterior circulation dissection is typically more associated with occipital and neck pain.
