“…In agreement with Comert et al and Ghanem et al studies, the detected lesions were located mainly in the right basal lung region [9,11], and unfortunately, we did not have an explanation for this. Regarding the size of the lesions, our study showed that the mean size of the lesions was 15.3 × 10.5 mm while, in Comert et al study, it was 22.9 × 31.2 mm [9] and, in Abootalebi et al study, it was 16.4 × 11.1 mm [10]; thus, there was no big difference in the mean size of the lesions in the three studies, and all of them had a mean size that was more than 10 mm.…”

“…In the current study, TUS demonstrated 17 subpleural hypoechoic lesions suggestive of PE in 12 out of 16 patients finally diagnosed as PE by CTPA with a mean of 1.3 lesion per patient which is lower than that was detected in Ghanem et al [11], and this could be attributed to the difference in the sample size between the two studies where the latter was larger.…”

Background: To determine the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of thoracic ultrasound (TUS) in patients with moderate to high clinical suspicion of pulmonary embolism (PE). Twenty-five patients with moderate or high clinical suspicion of PE were enrolled in a prospective study. The patients' ages were 20 to 50 years (mean age = 36 years). They were evaluated by TUS and standard contrast-enhanced CT pulmonary angiography (CTPA). Results: In comparison to and in correlation with CTPA, TUS was found true positive in 12 patients (48%), false positive in one patient (4%), true negative in eight patients (32%), and false negative in four patients (8%), with an overall sensitivity (75%), specificity (89%), positive predictive value (92%), negative predictive value (67%), and accuracy (80%). Conclusion: TUS with its high specificity and diagnostic accuracy is a noninvasive, widely available, cost-effective method which can be rapidly performed. A negative TUS study cannot rule out PE with certainty, but positive TUS findings with moderate/high suspicion for PE may prove a valuable bedside tool in the diagnosis of PE especially for critically ill and immobile patients, facilitating their immediate treatment.

Purpose Critically ill COVID-19 patients have an increased risk of developing pulmonary embolism (PE). Diagnosis of PE by point-of-care ultrasound (POCUS) might reduce the need for computed tomography pulmonary angiography (CTPA), while decreasing time-to-diagnosis. Materials & methods This prospective, observational study included adult ICU patients with COVID-19. Multi-organ (lungs, deep vein, cardiac) POCUS was performed within 24 h of CTPA, looking for subpleural consolidations, deep venous thrombosis (DVT), and right ventricular strain (RVS). We reported the scan time, and calculated diagnostic accuracy measures for these signs separately and in combination. Results 70 consecutive patients were included. 23 patients (32.8%) had a PE. Median scan time was 14 min (IQR 11–17). Subpleural consolidations' diagnostic accuracy was: 42.9% (95%CI [34.1–52.0]). DVT's and RVS' diagnostic accuracy was: 75.6% (95%CI [67.1–82.9]) and 74.4% (95%CI [65.8–81.8]). Their sensitivity was: 24.0% (95%CI [9.4–45.1]), and 40.0% (95%CI [21.3–61.3]), while their specificity was: 88.8% (95%CI [80.8–94.3]), and: 83.0% (95%CI [74.2–89.8]), respectively. Multi-organ POCUS sensitivity was: 87.5% (95%CI [67.6–97.3]), and specificity was: 25% (95%CI [16.9–34.7]). Conclusions Multi-organ rather than single-organ POCUS can be of aid in ruling out PE in critically ill COVID-19 and help select patients for CTPA. In addition, finding RVS can make PE more likely, while a DVT would preclude the need for a CTPA. Registration: www.trialregister.nl : NL8540.
