The inguinal region, specifically the femoral vasculature, is a commonly used site of injection for intravenous drug users (IVDU). Repeated puncture of the vessel wall results in breakdown and subsequent arterial pseudoaneurysm- dilatations or outpouching of blood vessels, which, if left untreated, can result in fatal complications such as rupture with hemorrhage, sepsis, or even limb loss. The current modalities for arterial pseudoaneurysms include Doppler ultrasound and computed tomography (CT) angiography, both of which play important roles in management and surgical planning. However, 3D cinematic rendering (CR), a novel CT post-processing technique, offers timely, highly detailed photorealistic images that more clearly display the relation of anatomical structures, allowing for greater diagnostic confidence and precise surgical planning, particularly useful in the emergency setting. In this pictorial review, we demonstrate role of 3D CR in diagnosis and management of femoral pseudoaneurysms in IVDU through 9 illustrative cases.
腹股沟区域，特别是股血管，是静脉注射吸毒者（IVDU）常用的注射部位。血管壁的反复穿刺会导致破裂，进而形成假性动脉瘤——血管的扩张或膨出，如果不治疗，可能会导致致命的并发症，如破裂伴出血、脓毒症，甚至肢体丧失。目前治疗假性动脉瘤的方法包括多普勒超声和计算机断层扫描（CT）血管造影，两者在管理和手术计划中都发挥着重要作用。然而，3D 电影渲染（CR）是一种新的 CT 后处理技术，它可以提供及时、高度详细的逼真图像，更清楚地显示解剖结构的关系，从而提高诊断信心和精确的手术计划，在紧急情况下特别有用。在本图片综述中，我们通过 9 个病例展示了 3D CR 在诊断和治疗 IVDU 股假性动脉瘤中的作用。
