title: Exostoses and vascular complications in the lower limbs: two case reports and review of the literature.
abstract: Exostosis is a very common bone tumor. Complications occur in 4% of the cases (nerve compression, exostosis degeneration, orthopedic complication); however, vascular complications are rare. This is the report of 2 cases of vascular complications that occurred in 2 patients-one with a solitary form and the other with hereditary multiple exostoses. A review of the literature found 57 cases of lower limb vascular complication, secondary to an exostosis. The most common vascular complication was the popliteal aneurysm. Femoral exostosis topography was found in 89% of the cases. A triggering trauma was found in 36% of the cases and the most common form was the solitary exostosis (58%). The treatment of these complications is surgical, and it treats the vascular lesion and the bone tumor at the same time. Surgical treatment of exostosis vascular complications is recommended as an urgent procedure to prevent the occurrence of irreversible damages.
