[Lesion of the triceps surae after sclerosing injection in the territory of the external saphenous vein].

Eight cases of injury of the muscle triceps surae after a sclerosing injection in the territory of the external saphenous vein, are reported. In one case, it concerned an extremely severe evolution with necessary amputation of the leg; in the seven other cases, the consequences were less severe but the rate of partial permanent disability increased from 10 to 30 p. cent. The etiology and the mechanism of these accidents are discussed. It seems that the possibility of an accidental injection of the arterial system causing the obstruction of intramuscular arterioli should be remembered. The treatment of sequelae will essentially be of an orthopedic nature with lengthening of the Achilles tendon in case of a severe retraction of the triceps surae.
