The purpose of this study was to evaluate the diagnostic performance of three-dimensional computed tomography angiography (3D-CTA) for arteriovenous malformations (AVMs) in the oral and maxillofacial region.
Sixty four-slice spiral CT angiography of oral or maxillofacial region was performed in 8 patients with surgically proven arteriovenous malformations. The morphologic features, size, location, boundary, and feeding and draining vessels of lesions were reviewed.
AVMs in 5 patients were located in the soft tissues and 3 were in the mandible. CTA of all cases showed tangles of disorganized vessels with well-defined borders. The feeding and draining vessels were enlarged and tortuous. Four patients had bone involvement.
Sixty four-slice spiral CTA can accurately demonstrate the morphological characteristics of AVMs.
本研究旨在评估三维计算机断层血管造影（3D-CTA）在口腔颌面部动静脉畸形（AVM）中的诊断性能。
对 8 例经手术证实的口腔颌面部动静脉畸形患者进行 64 层螺旋 CT 血管造影。回顾病变的形态特征、大小、位置、边界以及供血和引流血管。
5 例患者的 AVM 位于软组织中，3 例位于下颌骨中。所有病例的 CTA 均显示边界清晰的紊乱血管纠结。供血和引流血管扩张且迂曲。4 例患者有骨受累。
64 层螺旋 CTA 能准确显示 AVM 的形态特征。
