Purpose
Intraarterial injection therapy was proposed in 1942 by Nakayama and his co-workers as an effective pain-relief method. However, in recent years, this therapy has been virtually discarded. We reevaluated this therapeutic method in patients with radicular ischialgia, osteoarthritis and rheumatoid arthritis of knee joint.
Methods
For intractable pain of the lower limbs, 20m1 of 20% dextrose solution and active vitamin B1 were injected at the speed of 5-6 sec. into Arteria (A.) femoralis. The hemodynamics of A. dorsalis pedis before and after the injection were examined by the doppler and hydrogen-clearance methods. The behavior of the adrenocortico steroid hormone was also examined before and after the injection.
Results
Intraarterial injection therapy was performed in more than 50 patients. The pain was relieved successfully in the majority of the patients.
