概括
光学连贯断层扫描血管造影 (OCTA) 显示,视网膜血管密度降低与突然神经感官听力损失 (SSNHL) 的更差结果有关. 更薄的视网膜层可能预测SSNHL患者的听力恢复不佳.
科学领域:
- 眼科医生 眼科 眼科
- 神经学 神经学
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 突然感觉神经听力损失 (SSNHL) 是一种常见但不太了解的耳病.
- 预后因素和SSNHL的潜在病理生理学需要进一步调查.
- 眼睛的微循环可以提供SSNHL的见解,需要先进的成像技术.
研究的目的:
- 调查视网膜微血管变化与SSNHL严重程度和预后之间的关系.
- 探索眼睛微循环在SSNHL中的作用,使用光学连贯性断层扫描血管学 (OCTA).
- 为了确定SSNHL预后的潜在的非侵入性生物标志物.
主要方法:
- 一项前性队列研究,涉及88名SSNHL患者.
- 在受影响的耳朵上进行了OCTA,以分析视网膜血管结构,包括血管密度 (VD),血管长度密度 (VLD) 和胆头膜流量缺陷 (CCFD).
- 测量了视网膜神经纤维层 (RNFL) 和质细胞层 (GCL) 的厚度;使用修改后的美国耳鼻喉学会 - 头手术标准评估了听力恢复.
主要成果:
- 听力恢复不良的患者与听力改善的患者相比,RNFL和GCL显著较薄.
- 表面 (SCP) 和深层 (DCP) 毛细管视觉疾病与初始听力损失严重程度 (p <0.05) 有显著的负相关性.
- 降低RNFL和GCL厚度和降低SCP/DCP VD与较差的SSNHL预后和严重程度有关,这表明与动脉低 perfusion 的联系.
结论:
- 减少RNFL和GCL厚度可能作为SSNHL的预后标志物.
- SCP/DCP VD与听力损失严重程度之间的反相关性表明动脉低流有助于SSNHL.
- OCTA是一种有前途的非侵入性工具,用于评估眼部血流,并可能预测SSNHL患者的结果.

Aneurysm II: Clinical Manifestations and Diagnostic Studies
293
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Cardiovascular System Abnormal Findings II: Auscultation
557
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
405
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
