In this study, including 62 patients, or 104 lower extremities, the author demonstrates first, with the chi-2 test, that the method based on Photoplethysmography has a good diagnostic value (sensitivity: 92%, specificity: 88%). Then, with the Student t-test, he demonstrates that the advantage of Photoplethysmography in venous insufficiency is to differentiate easily normal subjects from subjects affected with valve insufficiency, and to establish the differential diagnosis between superficial valvular insufficiency and deep valvular insufficiency. On the contrary, in analyzing the discrepancies between clinical examination and the results of Photoplethysmography, he demonstrates that the diagnosis obtained with Photoplethysmography is limited in the presence of edema, isolated varicose veins, Phlebitis and arterial disease, or during an ineffective compression of the reflux of the superficial venous system. Finally, the author suggests an approach in patients with chronic venous insufficiency, based on clinical examination, Doppler examination and Photoplethysmography.
在这项研究中,纳入了62例患者,共104条下肢,作者首先通过卡方检验证明,基于光电容积脉搏波描记法的方法具有良好的诊断价值(敏感性:92%,特异性:88%)。然后,通过学生t检验,作者证明光电容积脉搏波描记法在静脉功能不全中的优势在于能够轻松区分正常受试者与瓣膜功能不全患者,并建立浅静脉瓣膜功能不全与深静脉瓣膜功能不全之间的鉴别诊断。相反,在分析临床检查与光电容积脉搏波描记法结果之间的差异时,作者证明在存在水肿、孤立性静脉曲张、静脉炎和动脉疾病时,或在浅静脉系统反流压迫无效时,光电容积脉搏波描记法所获得的诊断是有限的。最后,作者提出了一种针对慢性静脉功能不全患者的方法,该方法基于临床检查、多普勒检查和光电容积脉搏波描记法。
