Use of Ultrasonography for Lung Transplant Recipients on Postoperative Care

The authors report their findings regarding lung ultrasound profiles in a population of transplant recipients. Twenty-two patients were studied once each in multiple different ultrasound windows focusing on pleural, lung, and diaphragmatic signatures. All studies were performed in presumably otherwise healthy recipients at an outpatient follow-up visit at least 3 months after transplantation. Those with recent pulmonary infections or decline in lung function were excluded from enrollment. The majority of scans revealed otherwise normal lungs with lung sliding, but there were more abnormalities than one would expect in a healthy control group. Lung ultrasonography will likely never replace other cross-sectional imaging given its inherent visual limitations but adds another modality to interrogate the lung/pleural interface and diaphragmatic function.
