[Effect of lumbar sympathectomy on orthostatic reactivity of the arteries of the extremities in thromboangiitis obliterans].

Lumbar sympathectomy in majority of patients with thromboangiitis was found to be followed by a reduced pathogenetically reliable orthostatic and post-orthostatic++ spasm of the diseased arteries. Patients with persistent and continuous remission had normo- and hypotonic orthostatic reaction of the extremity vessels. Remote clinical results of the intervention on lumbar sympathetic ganglia were dependent on the degree of correction of local angiotonic and angiospastic disorders.
