Sonographic Resolution of B-Lines after Diuresis in a Pregnant Patient with Preeclampsia Associated Pulmonary Edema

Abstract

We describe a case of preeclampsia where lung ultrasonography facilitated the diagnosis of pulmonary edema while also showing real-time resolution of B-lines after diuresis. The diagnostic accuracy of B-line clearance using lung ultrasonography across diverse patient populations (heart failure, renal failure) holds promise for use in the obstetric patient population. To our knowledge this is the first report which shows real-time resolution of B-lines using lung ultrasonography in a pregnant patient with preeclampsia associated pulmonary edema. Given the established validity of this tool, we believe lung ultrasonography holds promise in the management of critically ill obstetric patients.
