Abstract：
Penetrating vascular injury has become the topic of interest with increased gun violence in the United States. The radiologist plays a crucial role in establishing and systemizing the signs of vascular injury such as intimal flap, dissection, pseudoaneurysm, rupture, and arteriovenous fistula. Various imaging techniques such as ultrasound Doppler, computed tomographic angiography (CTA), magnetic resonance angiography, and conventional angiography are being employed based on clinical recommendations. Of all the techniques, CTA has been shown to embrace a promising role in identifying vascular injuries with superior sensitivity, specificity, and accuracy. An acquaintance of the imaging features has been shown to improve the approach to trauma patients in clinical settings. This article details the imaging modalities and the features of the head-and-neck penetrating vascular injury.
摘要：
随着美国枪支暴力的增加，穿透血管损伤已成为人们感兴趣的话题。放射科医生在建立和系统化血管损伤的迹象，如内膜皮瓣，解剖,假性动脉瘤,破裂,和动静脉瘘.各种成像技术，如超声多普勒，CT血管造影(CTA),磁共振血管造影术,和常规血管造影正在根据临床建议使用。在所有的技术中，CTA已被证明在识别具有优异敏感性的血管损伤方面具有有希望的作用，特异性，和准确性。对影像学特征的了解已被证明可以改善临床环境中创伤患者的治疗方法。本文详细介绍了头颈部穿透性血管损伤的成像方式和特征。
