Ложные аневризмы сосудов нижних конечностей как осложнение наследственной экзостозной хондродисплазии у подростков (два клинических случая)

Abstract

The article describes two clinical cases of vascular complications related to hereditary exostose chondrodysplasia\xa0of the lower limbs in children. Despite early diagnostics the newgrowth was not timely removed. The anatomical\xa0localization of the exostoses in the vicinity of the main arterial trunks resulted in formation of pseudo-aneurysms due to a prolonged exposure of the vascular wall to the actively growing bone formations. After diagnostic imaging (ultrasonography and Doppler sonography, CT angiography, MR angiography of the vessels in the lower extremities) the authors performed a simultaneous resection of the femoral artery aneurysm with autovenous grafting and total resection of exostoses in both cases. Late follow up of both patients demonstrated vascular permeability at the graft site and no symptoms of stenosis were observed.
