title: [Post-traumatic aortic valve insufficiencies].
abstract: Aortic regurgitation due to closed chest trauma is rare. It is related either to a valve lesion itself (ruptured cusp) or to trauma of the ascending aorta (subadventitial rupture with prolapse of the underlying aortic valve cusp). Four cases are described, 2 men and 2 women aged 30 to 66 years, after severe injuries in road traffic accidents: three patients had rupture of the aorta and the other had isolated rupture of the non-coronary aortic valve cusp. This pathology is unique due to the pathogenic mechanism associated with multiple thoracic injuries (right costal flap, sternal fracture, pulmonary contusion ...). The polytraumatic context explains the diagnostic difficulties and the secondary importance of the valve problem. Late surgery of these lesions was conservative in 3 cases: valve replacement was necessary in 1 case. If the haemodynamic tolerance of the aortic regurgitation is good, surgery should be deferred until the polytraumatic emergency has been dealt with. Good surgical results, often with conservative procedures, encourage earl operation after the acute polytraumatic period.
