脑凸面蛛网膜下腔出血合并脑梗死两例报道并文献复习

Convexal Subarachnoid Hemorrhage Complicated with Cerebral Infarction:Two Cases Report and Literature Review

脑凸面蛛网膜下腔出血(cSAH)是非创伤性蛛网膜下腔出血的一种少见类型,合并脑梗死的病例罕见。本文报道的2例患者分别以言语不清、左侧肢体无力和头痛为主要表现,均通过影像学检查明确cSAH,且均伴右侧枕叶脑梗死和颅内大动脉狭窄。本文同时通过文献复习分析c SAH合并脑梗死的发病机制、临床表现、诊断、治疗及预后。对于有神经系统症状的患者应考虑cSAH的可能,重点完善颅脑及颅内动脉影像学检查以明确诊断及病因,尽早治疗,从而改善患者预后。

Convexal subarachnoid hemorrhage(cSAH)is a rare type of non-traumatic subarachnoid hemorrhage,and cases complicated with cerebral infarction are occasionally reported.The main manifestations of the two patients reported in this paper were dysphasia,left limb weakness and headache.The cSAH diagnosis of both patients was confirmed by imaging examination,accompanied with right occipital lobe infarction and intracranial artery stenosis.The pathogenesis,clinical manifestation,diagnosis,treatment and prognosis of cSAH complicated with cerebral infraction were further analyzed through literature review.For patients with neurological symptoms,the possibility of cSAH should be considered,brain and vascular imaging examinations should be completed to clarify the diagnosis and cause for early treatment and improved patient prognosis.
