背景和目的：椎旁动静脉分流（PVAVS）是罕见的。硬膜内静脉系统是否参与引流可能通过特定的病理生理机制导致临床特征的差异。本研究旨在全面评价PVAVS伴或不伴硬膜内引流的自然病程和临床结局。方法：回顾性分析了来自2个研究所的64例连续的PVAVS患者。如果硬膜内静脉参与引流，则将病变归类为A型（n=28）;否则，将其归类为B型（n=36）。分析了从首次就诊到末次随访的临床过程。结果：A型分流患者年龄较大（52.5岁对35.5岁，P
Background and Purpose: Paravertebral arteriovenous shunts (PVAVSs) are rare. Whether the intradural venous system is involved in drainage may lead to differences in clinical characteristics through specific pathophysiological mechanisms. This study aims to comprehensively evaluate the natural history and clinical outcomes of PVAVSs with or without intradural drainage. Methods: Sixty-four consecutive patients with PVAVSs from 2 institutes were retrospectively reviewed. Lesions were classified as type A (n=28) if the intradural veins were involved in drainage; otherwise, they were classified as type B (n=36). The clinical course from initial presentation to the last follow-up was analyzed. Results: The patients with type A shunts were older at presentation (52.5 versus 35.5 years, P
