Vascular malformations usually have an impact on bones because of hemodynamic disturbances in the muscular and osteoperiosteal systems. In fact, even when these structures are not involved by arterial or venous malformations, the blood flow is altered in them. The consequences for bones affect the longitudinal growth of the skeleton of the malformed limb. Growth rarely becomes slower. On the contrary, the condition usually results in an acceleration of bone growth, which results in an excess in the length of the limb presenting with the vascular malformation. This overlengthening may be variably great, and the therapeutic indications must be adapted to its extent. When it is slight, compensation is sufficient to balance the pelvis. Conversely, when it is greater, its correction must be surgical. This surgery is aimed at equalizing the lower limbs, either by slowing down epiphyseal growth and shortening the longer side, or by progressively lengthening the other side, as the case may be. The respective indications of these methods must be carefully considered and adapted to each case, in order to obtain the best possible result with the smallest surgical risk. |
