[Regional drug-induced sympathicolysis in patients with arterial occlusive disease].

Regional drug-induced sympathectomy is a modification of Bier's block technique. By applying this method skin perfusion in patients with occlusions of lower leg arteries or functional disturbance of peripheral circulation can be improved. Under optimal technical conditions effects of regional and surgical sympathectomy are comparable. Fluorescence angiography can be applied to assess the effectiveness of drug-induced as well as surgical sympathectomy.
