Lung hypoperfusion in children with complicated pneumonia may be assessed by Doppler ultrasound of the main pulmonary arteries.

Patients with complicated pneumonia usually require invasive procedures and have a protracted course of the disease, although most children have a complete recovery with no evident long-term sequelae. Recovery is monitored by clinical findings, biochemical measurements in blood and imaging studies of the chest (x-ray and ultrasound). Lung ultrasound has been widely used in the study of pneumonia and its complications, but Doppler ultrasound, and echocardiography have been less often. This article is protected by copyright.
