| 中文摘要 | 利用脈量記錄儀及都卜勃超音波來診斷深部靜脈血栓肇始於Dr Raines。我們利用其所創設之脈量記錄儀靜脈評估點數來測試所有疑似深部靜脈血栓患者,並以X光靜脈顯影之結果將其區分為健、患肢兩類。經分析發現評估點數以1.2及3.2為值則有極佳之敏感度(如果點數小於1.2則為100%)及特異度(如點數大於3.2則為100%)。如果以健肢所得評估點數之95% Confidence level (2.4)為診斷值,則敏感度為92.1%,特異度為94%,準確度為93.0%。由研究結果得知,如果評估點數小於1.2或是大於3.2則侵襲性的靜脈顯影術是不必要的。 |
| 英文摘要 | The pulse volume recorder combined with a doppler ultrasound could be applied to deep vein thrombosis as a noninvasive vascular diagnostic tool. We used a PVR score that was designed by Dr. Raines to evaluate suspected extremities. All limbs had x-ray venogram. We then divided the patients into two groups known as positive and negative deep vein thrombosis based on finding of the venogram. After the data was analyzed, we found the threshold (critical) value of the PVR score 1.2 & 3.2 which could supply the highest sensitivity (100% if score <1.2)and specificity (100% if score >3.2). If we used a 95% confidence level of normal leg PVR score (2.4) as a diagnostic threshold value, the sensitivity was 92.1%, specificity 94.0%, accuracy 93.0%, predict positive value 91.3%, and predict negative value 94.5%. According to these studies, we concluded that invasive venography is not indicated if the PVR score is below 1.2 or above 3.2. |
