[Traumatic rupture of the middle lobe bronchus and pulmonary artery: considerations apropos of a case].

The authors report the case of a road accident which resulted in rupture of the middle lobe bronchus. There was an associated lesion of the pulmonary artery. Treatment was conservative after primary evaluation of the right pulmonary artery at its origin. Vascular trauma associated with rupture of the main bronchi is rare. The prevalence is greater in the case of rupture of the more distal lobar bronchi. It is important to be aware of this possibility, and the pulmonary artery must be inspected before such lesions are treated surgically.
