概括
周围视网膜新血管化 (PNV) 在多发性糖尿病视网膜病变 (PDR) 中很常见,通常与其他新血管化并存. 这凸显了对超越标准领域的全面成像的需求,特别是在年轻患者中.
科学领域:
- 眼科医生 眼科 眼科
- 糖尿病视网膜病变研究研究
- 医疗成像医学成像
背景情况:
- 增殖性糖尿病视网膜病变 (PDR) 是视力丧失的主要原因.
- 标准成像可能会错过外围视网膜新血管化 (PNV).
- 超广场光体血管学 (UWFFA) 提供了视网膜的更广泛的视图.
研究的目的:
- 用UWFFA确定PNV在未经治疗的PDR患者中的流行率和分布.
- 分析PNV与其他神经血管病变的关联.
- 评估PNV在PDR管理中的临床相关性.
主要方法:
- 追溯性观察性研究,对61名以前未接受治疗的PDR患者97只眼睛进行了观察.
- 在UWFFA图像上应用网格覆盖,以划分ETDRS和外围场.
- 根据位置,新血管化的分类为NVD,NVE和PNV.
主要成果:
- 在57.7%的眼睛中存在PNV,很少单独发生 (3.1%).
- PNV经常与磁盘的新血管化 (NVD) 和/或其他地方的新血管化 (NVE) (74.7%) 一起存在.
- 在扩展场6 (43.3%) 中,PNV的患病率最高,与年轻患者 (≤50岁) 有关.
结论:
- 在PDR患者中,视网膜新血管化扩展到ETDRS7场区域之外.
- PNV很常见,通常与后部新血管化共存,支持继续使用ETDRS成像.
- 警监测和量身定制的管理是至关重要的,特别是对于PNV的年轻PDR患者.

38
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
