Abstract:
The long-term efficacy of various treatments for intermittent claudication was studied to determine which regimen should be selected. Two hundred and nineteen patients with arteriosclerosis obliterans (ASO) and intermittent claudication of the extremities were divided into two groups based upon the type of treatment: 1) 170 patients who underwent arterial reconstruction and 2) 49 receiving conservative treatment. Fifty-five patients with Buerger's disease (TAO) with intermittent claudication were divided into three groups: 1) 17 patients who underwent arterial reconstruction, 2) 15 with lumbar sympathectomy, and 3) 23 receiving conservative treatment. The background factors of both disease groups were analyzed, and the changes in claudication, the quality of life, and the survival rate were followed up. Among ASO patients, the improvement of intermittent claudication was significantly better in the arterial reconstruction group (p<0.001) than in the conservative treatment group. The quality of life and 5-year surival rate were also superior in the arterial reconstruction group (p<0.01), and they were closely related to the improvement of intermittent claudication. On the other hand, there was no significant difference in any of these parameters between the three groups of TAO patients. This discrepancy in outcome was concluded to be due to differences in the background factors of the two diseases. Accordingly, the treatment for intermittent claudication should be discussed making a clear distinction between ASO and TAO. In conclusion, the treatment of choice for intermittent claudication is arterial reconstruction in ASO patients, whereas surgical treatment should only be considered for TAO patients when conservative therapy is ineffective.
