Lung ultrasound (LUS) is a growing and fascinating field of application for ultrasound imaging. Despite the difficulties in imaging an organ largely filled with air, the potential benefits originating from an effective ultrasound method focusing on monitoring and diagnosing lung diseases represent a tremendous stimulus for research in this direction. This paper presents a technical review where, after a brief historical overview, the current limitations of LUS imaging are discussed together with a description of the physical phenomena at stake. Next, the paper focuses on the latest technical developments of LUS.

Summary In this month's Small Animal Review, we summarise three recently published papers from other veterinary journals. The papers for this issue explore the impact of open registries on inbreeding, in the working Australian Kelpie population particularly, and the impact of vehicle trauma on the canine shock index, as well as the potential role for lung ultrasound in monitoring for cardiogenic pulmonary oedema in dogs being treated for left-sided congestive heart failure.

Introduction : In acute ischemic stroke patients, current guidelines recommend noninvasive vascular imaging to identify intracranial vessel occlusions (VO) that may benefit from endovascular treatment (EVT). However, VO can be missed in CT angiography (CTA) readings. We aim to evaluate the impact of consistently including CT perfusion (CTP) in admission stroke imaging protocols on VO diagnosis and EVT rates. Methods : We included patients with a suspected acute ischemic stroke that underwent urgent non‐contrast CT, CTA and CTP from April to October 2020. Hypoperfusion areas defined by Tmax>6s delay (RAPID software), congruent with the clinical symptoms and a vascular territory, were considered due to a VO (CTP‐VO). Cases in which mechanical thrombectomy was performed were defined as therapeutically relevant VO (EVT‐VO). For patients that received EVT, site of VO according to digital subtraction angiography was recorded. Two experienced neuroradiologists blinded to CTP but not to clinical symptoms, retrospectively evaluated NCCT and CTA to identify intracranial VO (CTA‐VO). We analyzed CTA‐VO sensitivity and specificity at detecting CTP‐VO and EVT‐VO respecitvely. We performed a logistic regression to test the association of Tmax>6s volumes with CTA‐VO identification and indication of EVT. Results : Of the 338 patients included in the analysis, 157 (46.5%) presented a CTP‐VO, (median Tmax>6s: 73 [29‐127] ml). CTA‐VO was identified in 83 (24.5%) of the cases. Overall CTA‐VO sensitivity for the detection of CTP‐VO was 50.3% and specificity was 97.8%. Higher hypoperfusion volume was associated with an increased CTA‐VO detection, with an odds ratio of 1.03 (95% confidence interval 1.02‐1.04) (figure). DSA was indicated in 107 patients; in 4 of them no EVT was attempted due to recanalization or a too distal VO in the first angiographic run. EVT was performed in 103 patients (30.5%. Tmax>6s: 102 [63‐160] ml), representing 65.6% of all CTP‐VO. Overall CTA‐VO sensitivity for the detection of EVT‐VO was 69.9%. The CTA‐VO sensitivity for detecting patients with indication of EVT according to clinical guidelines was as follows: 91.7% for ICA occlusions and 84.4% for M1‐MCA occlusions. For all other occlusion sites that received EVT, the CTA‐VO sensitivity was 36.1%. The overall specificity was 95.3%. Among patients who received EVT, CTA‐VO was not detected in 31 cases, resulting in a false negative rate of 30.1%. False negative CTA‐VO cases had lower Tmax>6s volumes (69[46‐99.5] vs 126[84‐169.5]ml, p<0.001) and lower NIHSS (13[8.5‐16] vs 17[14‐21], p<0.001). Conclusions : Systematically including CTP perfusion in the acute stroke admission imaging protocols may increase the diagnosis of VO and rate of EVT.

The Impact

Objective Semiquantitative lung ultrasound improves the timeliness of surfactant replacement, but its financial consequences are unknown. We aim to investigate if the ultrasound-guided surfactant administration influences the general costs of surfactant therapy for preterm neonates affected by respiratory distress syndrome. Study Design This is a pharmacoeconomic, retrospective, and before-and-after study investigating the impact of ultrasound-guided surfactant replacement (echography-guided Surfactant THERapy [ESTHER]) on pharmaceutical expenditure within the ESTHER initiative. Data extracted from the institutional official database hosted by the hospital administration for financial management were used for the analysis. We analyzed the number of surfactant administrations in neonates of gestational age ≤326/7 weeks, and the number of surfactant vials used from January 1, 2014 to June 30, 2014 (i.e., during the period of standard surfactant administration policy) and from July 1, 2016 to December 31, 2018 (that is during ESTHER policy). Results ESTHER did not modify surfactant use, as proportion of treated neonates with RDS receiving at least one surfactant dose (Standard: 21.3% vs. ESTHER: 20.9%; p = 0.876) or as proportion of used vials over the total number of vials opened for neonates of any gestational age (Standard: 37% vs. ESTHER: 35%; p = 0.509). Conclusion Ultrasound-guided surfactant replacement using a semiquantitative lung ultrasound score in preterm infants with RDS does not change the global use of surfactant and the related expenditure.
