Positive Pulmonary Computed Tomography Angiography in Patients with Suspected Acute Pulmonary Embolism: Clinical Prediction Rules, Thromboembolic Risk Factors, and Implications for Appropriate Use.

CONCLUSION: This was the first study to investigate prevalence of positive pulmonary CTA for acute PE in a large university-based tertiary referral hospital in Thailand Prevalence of positive test for PE by pulmonary CTA in patients with suspected acute PE was approximately 33%. Sign of DVT S1Q3T3 pattern, and enlarged right pulmonary artery were significant clinical predictors of positive pulmonary CTA. Positive pulmonary CTA result was much less likely in patients with low probability, especially in the absence of thromboembolic risk factors and positive D-dimer This study emphasized the importance and value of accurate and effective triage in reducing both patient care costs and patient radiation exposure.
