Perthes syndrome: a pediatric case

“…It is a clinical syndrome associating anecchymotic mask consisting of cervicofacial cyanosis, petechiae and subconjunctival hemorrhage to neurological and ocular symptoms. It follows asudden, severe and transient compression of the chest and/or the upper part of the abdomen, generally after road traffic accidents [1][2][3][4].…”

“…The physiopathology producing the classic findings in traumatic asphyxia involves a marked increase in thoracic pressure transmitted through the valveless superior vena cava and veins of the head and neck. A Valsalva maneuver as part of a pre-impact fear response may help to produce the marked venous pressure, reversal of venous flow, and capillary rupture, which result in the distinctive physical signs [1][2][3][4]. The treatment includes rapid chest decompression andcardiopulmonary resuscitation.…”
