[The causes and prevention of neurological disorders in the surgical treatment of varicose disease].

Frequency of the appearance of neurological disturbances was studied after operative treatment of varicose disease in 422 patients. The topographo-anatomical correlations of subcutaneous nerves and lower extremity veins were also investigated in 40 corpses. The authors' original method was used in operations on 82 patients. Neurological disturbances-such as disturbances of skin sensitivity-were noted in 38.6% of the investigated people. Their cause is thought to be the mutual sheath between the subcutaneous vein and nerves in the shin. The endovasal autovenous occlusion of the main trunks of the subcutaneous shin vein with the help of the autovein taken from the thigh was made to avoid traumatism.
