Vascular injuries due to pelvic trauma are unusual in children. They resulted from important pelvic injuries with section of external iliac vessels, or of a contusion with thrombosis. These lesions required an angiography witch indications are = four or more units of blood transfusion within 24 hours, or a half blood mass in one hour. Truncal vessel lesions are associated with important pelvic fractures and associated lesions, requiring a surgical treatment. They are revealed by an important bleeding or an ischemia, and confirmed by an angiography. Indications for retroperitoneal hematomas are less important, but an important bleeding, with hypotension require an angiography and a selective embolization. Percutaneous transcatheter embolization is the procedure of choice for controlling massive pelvic retroperitoneal hemorrhage. We reported 14 cases of vascular injuries; 9 required a surgical treatment for a truncal vessel section and 3 were associated with important pelvic lesion; 5 large retroperitoneal hemorrhage were treated by selective embolisation.
