Delayed common femoral artery stenosis due to blunt trauma.

Arterial occlusion or stenosis due to blunt trauma is rare. Only isolated examples have been reported. The majority result from sport-related trauma or are iatrogenic in nature. The clinical importance of blunt trauma is that it can create delayed vascular stenosis but few symptoms at the time of the incident. This is even more important in children and adolescents as any delay in diagnosis can lead to severe sequelae such as limb shortening and other growth disturbances. We here report a patient with common femoral artery stenosis after a bicycle injury in whom, apparently uniquely, delayed symptoms developed after eight months.
