[Effects of selective radicular block for reflex sympathetic dystrophy].

We have analyzed therapeutic effects of selective radicular block for 30 patients of reflex sympathetic dystrophy with residual intractable pain after neurolytic sympathetic ganglion blockade. Ten patients showed complete pain relief after the therapy with a effective rate of 66.7%. Minor side effects were observed in 3 cases (10%). When examined 2 month after the therapy, the effect had persisted in 16 cases in successful 20 cases. The therapy could not relieve complaints induced by numbness and neuroma. By the therapy, patients with diffuse pain were more comfortable than patients with regional pain. In indicated cases, this therapy is useful for residual complain of reflex sympathetic dystrophy after neurolytic sympathetic ganglion block.
