Abstract
Obstructive arterial diseases were treated by means of the combination therapy with endoarterectomy, endoscopic observation and laser angioplasty. Operation method was as follows; The first, endoarterectomy was done from the distal end of the obstructive area. And the next, the condition of the vessel wall was observed by the angioscope, and residual obstructive tissue was removed with laser irradiatiation. The vessel wall after operation was observed again, and closed. Eight cases with arteriosclerosis obliterans were treated with this method. Angiographical findings and ankle pressure index of the whole cases were excellently improved after operation. In addition to the therapy, arteries of the limbs which were under the state of gangrene were investigated after amputation. As the result, the obstructive tissues were segmental and it was suggested that the limb could be salvaged, if the segmental obstructions were released.
We believe that this method is useful for the treatment of obstructive peripheral arterial diseases.
