[Results of transabdominal chemical sympathectomy of the lower extremities directed by computer tomography].

The authors evaluated 47 transabdominal lumbar sympatectomies by ethyl alcohol with a control by computer tomography in surgically unsolved disorders in the passage through lower extremity arteries. In four fifths of the patients there was an increase in ischaemia manifestations, in one fifth there was no improvement. No substantial difference was found between the results of sympatectomy in diabetic and nondiabetic patients. The method should be applied sooner than a cutaneous ischaemic defect develops.
