Pseudoaneurisma traumático de rama muscular de arteria femoral superficial en un paciente pediátrico

Pseudoaneurysm or 'false aneurysm' is defined asan abnormal arterial dilatation produced by an injury to its wall that does not affect the three parietal layers like in 'true' aneurysms. In general, false aneurysms are related to traumatisms and, less frequently, to inflammatory disease of vascular endothelium. Clinically, it shows a pulsatile, painful hematoma in the affected region. The initial diagnosis is usually achieved by Doppler ultrasound showing a hypoechoic image in relation to a blood vessel or its wall. Due to the low prevalence of false aneurysm, it is commonly confused with skin and soft tissue's infections or with thrombosis. There are different options of treatment, from extrinsic compression to open surgery. We describe the case of a 13-year-old patient with traumatic false aneurysm of a muscular branch of femoral artery, successfully managed with endovascular exclusion of the lesion with microcoils.
