颅内动脉瘤患者头痛的影响因素

Influencing Factors of Headache in Patients with Intracranial Aneurysm

颅内动脉瘤是指脑动脉内腔的局限性异常扩大造成动脉壁的一种瘤状突出,其发病原因为局部脑动脉管壁先天性缺陷、腔内压力增高,该病是蛛网膜下腔出血的主要病因。颅内动脉瘤的典型症状为头痛、眩晕,多数患者伴有持续性剧烈头痛,影响治疗的开展。目前关于颅内动脉瘤患者产生头痛的机制尚未明确,可能是由于其动脉上的疼痛神经纤维受到不同程度的激活,当发生神经受压迫、动脉瘤高搏动、急性刺激、动脉瘤出血等时,患者则会产生头痛。本文就颅内动脉瘤患者产生头痛的机制以及影响因素作一综述,以期为临床治疗提供参考。

Intracranial aneurysm refers to a localized abnormal enlargement of the cerebral artery lumen that causes a tumor-like protrusion of the arterial wall.The cause of the disease is a congenital defect of the local cerebral artery wall and increased intraluminal pressure.The disease is subarachnoid space the main cause of bleeding.The typical symptoms of intracranial aneurysms are headache and dizziness.Most patients are accompanied by persistent severe headaches,which affects the development of treatment.At present,the mechanism of headache in patients with intracranial aneurysms is not yet clear.It may be because the painful nerve fibers on their arteries have been activated to varying degrees.When nerve compression occurs,the aneurysm has high pulsation,acute stimulation,and aneurysm bleeding.The patient will have a headache.This article reviews the mechanism and influencing factors of headache in patients with intracranial aneurysms,in order to provide a reference for clinical treatment.
