NCT03971136

Brief Summary

ATS (acute thoracic syndrome) refers to acute pulmonary involvement in a sickle cell patient. The diagnosis is based on the association of clinical signs (fever or respiratory symptoms) with a recent pulmonary infiltrate on the chest x-ray. The main objective of the study is to evaluate the place of the pulmonary ultrasound for the diagnosis of ATS, in comparison with frontal chest x-ray.
