腹股沟区,特别是股血管,是静脉吸毒者(IVDU)的常用注射部位。反复穿刺血管壁导致破裂和随后的动脉假性动脉瘤-血管扩张或出袋。which,如果不及时治疗,会导致致命的并发症,如出血破裂,脓毒症,甚至断肢.动脉假性动脉瘤的当前模式包括多普勒超声和计算机断层扫描(CT)血管造影,两者都在管理和手术计划中发挥重要作用。然而,3D电影渲染(CR),一种新颖的CT后处理技术,报价及时,高度详细的真实感图像,更清晰地显示解剖结构的关系,允许更大的诊断信心和精确的手术计划,在紧急情况下特别有用。在这篇图片评论中,我们通过9例病例证明了3DCR在IVDU中股动脉假性动脉瘤的诊断和治疗中的作用.
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.
