颅内巨大动脉瘤的DSA表现及临床分析

目的：探讨颅内巨大动脉瘤的临床表现及脑血管造影特征。材料和方法：对２０例颅内巨大动脉瘤患者的临床、病理及脑血管造影资料进行全面分析，探讨颅内巨大动脉瘤发生的部位与其临床表现之间的关系以及它们的脑血管造影特征。结果：颅内巨大动脉瘤一般瘤颈较宽，瘤腔内容易血栓形成。其占位效应可直接或间接的引起临床症状和体征。同一部位的巨大动脉瘤可能会有不同的临床表现，而不同部位的巨大动脉瘤可能会有相同的临床表现。结论：临床症状和体症对判断颅内巨大动脉瘤的发病部位没有特异性，脑血管造影对显示颅内巨大动脉瘤的部位和特征具有重要价值。

DSA Features and Clinical Presentations of Intracranial Giant Aneurysms

urpose:The aim of the study is to elucidate the clinical presentation and cerebral angiographic features of giant intracranial aneurysms. Materials and Methods:We retrospectively analyzed clinical,cerebral angiographic and pathological data of 20 patients with giant intracranial aneurysms and studied the correlation amorg clinical presentations locations and cerebral angiographic features of giant intracranial cerebral aneurysms.Results:The neck of giant intracranial aneurysms were broader and there by predisposed for thrombi, for mation.Symptoms and signs were directly or indirectly attributed to the intracranial mass effect by the giant aneurysms.Aneurysms in different locations may give rise of same symptom and sign,while aneurysms in same location may cause different symptoms and signs.Conclusion:Clinical symtoms and signs are not specific for determining the site of aneurysms, Cerebral angiography was particularly useful in presenting the characterization of giant intracranial aneurysms.
