目的 :通过对16例经DSA证实的纯硬脑膜动静脉瘘的血管造影表现进行描述及分类、临床症状的复习 ,探讨纯硬脑膜动静脉瘘的DSA分类与临床症状的相关性。材料与方法 :文中16例纯硬脑膜动静瘘均行双侧颈内、外动脉及椎动脉血管造影检查。通过对其血管造影表现进行描述及分类 ,做DSA分类与临床症状的对照分析。结果 :16例纯硬脑膜动静脉瘘中 ,Ⅰ型9例 ,Ⅱ型4例 ,Ⅲ型2例 ,Ⅳ型1例。Ⅰ型的临床症状多为非侵袭性的良性表现 ,Ⅲ、Ⅳ型的临床症状多为侵袭性的恶性表现 ,Ⅱ型的临床症状介于侵袭性与非侵袭性表现之间。结论 :全脑血管造影是确诊和研究该病唯一可靠的手段、方法。患者的临床表现与DSA分类密切相关。
OBJECTIVE: To describe and classify the angiographic manifestations of 16 pure DSA-proved pure dural arteriovenous fistulas and review the clinical symptoms, and to explore the correlation between DSA classification and clinical symptoms of pure dural arteriovenous fistula. Materials and Methods: 16 cases of pure dural arteriovenous fistula were performed bilateral internal carotid artery, external artery and vertebral artery angiography. Through the angiography performance description and classification, do DSA classification and clinical symptoms of controlled analysis. Results: In 16 cases of pure dural arteriovenous fistula, there were 9 cases of type Ⅰ, 4 cases of type Ⅱ, 2 cases of type Ⅲ and 1 case of type Ⅳ. The clinical symptoms of type I were mostly benign and noninvasive. The clinical symptoms of type III and IV were mostly aggressive malignant manifestations. The clinical symptoms of type II were between aggressive and noninvasive manifestations. Conclusion: Cerebral angiography is the only reliable method and method for diagnosing and studying the disease. The patient’s clinical manifestations are closely related to the DSA classification.
