概括
光学连贯断层扫描血管造影 (OCTA) 显示,在肉病患者中,深毛细管血管密度 (DCP-VD) 降低,这表明早期的亚临床微血管变化. 这些发现表明,OCTA可以在临床症状出现之前检测到微妙的视网膜变化.
科学领域:
- 眼科医生 眼科 眼科
- 类风湿病学 类风湿病学
- 医疗成像医学成像
背景情况:
- Sarcoidosis 是一种多系统性炎症性疾病,可影响眼睛.
- 视网膜和冠状腺微血管变化是疾病活动和进展的潜在指标.
- 光学连贯断层扫描血管学 (OCTA) 提供了一种非侵入性方法来可视化和量化视网膜微血管.
研究的目的:
- 在使用OCTA的沙尔科毒症患者中评估视网膜和冠状腺微血管变化.
- 评估这些微血管变化与临床表型和疾病持续时间的关联.
- 为了确定OCTA是否能够检测到沙尔科病的亚临床微血管妥协.
主要方法:
- 一项横截面研究,涉及76名沙尔病患者 (肺,肺+眼,肺+肺外) 和31名健康对照.
- OCTA用于测量表面 (SCP) 和深层毛细血管 (DCP),叶无血管区 (FAZ) 区域,胆毛细血管流和辐射周毛细血管 (RPC) 网络中的血管密度 (VD).
- 统计分析包括ANOVA,Tukey hoc后期测试和相关性分析,以比较群体并评估关系.
主要成果:
- 两组之间SCP-VD,RPC-VD,FAZ区域或choriocapillaris流量没有发现显著差异.
- 在DCP-VD中观察到显著的差异,特别是在foveal和perifoveal区域 (p=0.005和p=0.012).
- 与对照组相比,在所有类型的沙尔科发症亚组中,DCP-VD显著较低,即使在没有临床眼部参与的人群中也是如此. 没有发现与疾病持续时间有显著的相关性.
结论:
- 深毛细管血管密度 (DCP-VD) 选择性地降低了型发病,这表明早期的亚临床微血管妥协.
- OCTA是一种有价值的非侵入性工具,用于检测沙尔科毒症中微妙的视网膜微血管变化,可能在临床症状出现之前.
- 需要进行进一步的纵向研究,以探索这些OCTA研究结果在肉类突发症的预后影响.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
570
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
