透明质酸(H.A.)填充剂注射与早期,temporary,和延迟发作的并发症。具有多普勒分析的高分辨率超声(HRUS)已越来越多地用于检测和识别此类并发症。我们全面描述了与H.A.填充剂注射相关的非血管并发症的最常见超声检查结果。这次回顾,横断面观察研究是在波哥大的皮肤超声参考中心进行的,哥伦比亚。超声报告记录了H.A.填充剂注射的非血管并发症的超声检查结果。在50名患者的队列中记录了52例并发症(女性,88%)。眶下区域是最常见的受影响地点(23%),其次是鼻唇(22%)。廷德尔效应是最常见的并发症(25%),其次是流变学变化(21%)和假肉瘤(异物肉芽肿)反应(15%)。廷德尔效应因其独特的超声特征而脱颖而出。我们讨论其他并发症的超声检查结果和发病机理,包括填料迁移,早期超敏反应,无菌脓肿,过度校正,和填充材料的相互作用。H.A.填充并发症的临床表现可能令人困惑,延误及时诊断和治疗。具有多普勒分析的HRUS是避免不必要治疗并确保及时诊断和治疗的宝贵工具。
Hyaluronic acid filler injections have been associated with early, temporary, and delayed-onset complications. High-resolution ultrasound with Doppler analysis has been increasingly used to detect and identify such complications. We comprehensively describe the most common ultrasonographic findings of nonvascular complications associated with hyaluronic acid filler injections. This retrospective, cross-sectional, observational
study was conducted at a reference center for dermatologic ultrasound in Bogotá, Colombia. Ultrasound reports documented the ultrasonographic findings of nonvascular complications of hyaluronic acid filler injections. Fifty-two complications were documented in a cohort of 50 patients (women, 88%). The infraorbital region was the most common site affected (23%), followed by the nasolabial region (22%). The Tyndall effect was the most common complication (25% of all), followed by changes in
rheology (21%) and pseudosarcoidal (foreign body granuloma) reaction (15%). The Tyndall effect stood out for its distinctive ultrasonographic characteristics. We discuss the ultrasonographic findings and pathogenesis of other complications, including filler migration, early hypersensitivity, aseptic abscess, overcorrection, and filler material interaction. The clinical presentation of hyaluronic acid filler complications can be confusing, delaying timely diagnosis and treatment. High-resolution ultrasound with Doppler analysis is a valuable tool for avoiding unnecessary treatments and ensuring timely diagnosis and treatment.
