Abstract

Objectives: Evaluation of the literature assessing the use of thermography, a non-invasive imaging modality that detects pathological temperature variation, in recognising superficial venous insufficiency (SVI).

Methods: A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were screened by two individuals and data was subsequently extracted. Methodological quality was assessed with Cochrane's risk of bias tool.

Results: Four studies comprising 363 patients were included. Three studies identified increased temperature uptake in veins with incompetent valves on venous duplex (p < .05). One study reported sensitivity and specificity of thermal imaging in SVI as 98.30% (95% CI, 95.2%-99.4%) and 100% (95% CI 85.7%-100%) respectively.

Conclusion: Thermal imaging could act as a screening tool in SVI. This review highlights a lack of high-quality prospective studies evaluating the role of thermal imaging as a diagnostic tool that could expedite the assessment of patients.

热成像作为浅静脉功能不全的诊断工具--系统综述。

目的：评估使用热成像（一种检测病理温度变化的无创成像模式）识别浅静脉功能不全（SVI）的文献：评估使用热成像（一种检测病理温度变化的非侵入性成像方式）识别浅静脉功能不全（SVI）的文献：方法：根据《系统综述和元分析首选报告项目》（Preferred Reporting Items for Systematic Reviews and Meta-Analyses，PRISMA）指南进行系统综述。文章由两人筛选，随后提取数据。采用 Cochrane 的偏倚风险工具对方法学质量进行了评估：结果：共纳入四项研究，包括 363 名患者。三项研究发现，静脉二联瓣膜功能不全的静脉摄取的温度升高（p < .05）。一项研究报告称，热成像对 SVI 的敏感性和特异性分别为 98.30% (95% CI, 95.2%-99.4%) 和 100% (95% CI 85.7%-100%) ：结论：热成像可作为 SVI 的筛查工具。本综述强调了缺乏高质量的前瞻性研究来评估热成像作为诊断工具的作用，而热成像可加快对患者的评估。
