摘要

目的：探讨CTA多种后处理方法在口腔颌面部动静脉畸形（AVM）诊断中的价值。方法：分析经手术病理证实的8例口腔颌面部AVM的MSCT表现，着重分析其CTA表现。结果：8例患者中，发生于软组织内5例，下颌骨3例。5例软组织者，边界均不清楚，无钙化，1例肿瘤内可见出血，增强扫描明显强化。3例下颌骨者，均表现为明显膨胀性溶骨性骨质破坏，增强扫描明显强化。CTA通过VR及MIP后处理能够清楚地显示病灶的供血动脉及引流静脉。结论：CTA通过不同的三维重建方法能全方位、直观、详细地显示口腔颌面部AVM病灶及血管情况。

Abstract

Objective: To determine the value of computed tomography angiography(CTA) in the diagnosis of arteriovenous malformations in the oral and maxillofacial regions using imaging reformating techniques. Methods: A total of 8 patients with surgically and pathologically proved arteriovenous malformations in the oral and maxillofacial regions were enrolled. The imaging features of the lesions especially the CTA findings were retrospectively analyzed. Results: In the 8 patients, lesions were located in soft tissues in 5 patients and mandible in 3 patients. All the 5 patients lesions located in soft tissues had an ill-defined boundary without calcification. Hemorrhage was seen in 1 patient. All the 5 patients had obvious enhancement. An obvious expansive osteolytic lesions was found in 3 patients located in mandible. Also, an obvious enhancement was seen in the 3 patients. Through reformating techniques such as VR and MIP, CTA could well detect the feeding and draining vessels of the lesions. Conclusion: MSCT can directly, comprehensively show the lesion details and vessels of AVM located in oral and maxillofacial by means of different 3D image reformating technique.
