- Purpose: In order to evaluate the result of medical treatment and compare with surgical management in infrainguinal arterial occlusion, we analyzed 145 cases of infrainguinal chronic arterial occlusion that admitted our department during recent 5 years.
Method: Patients were grouped into 2 according to their treatment. Group 1 was patients who underwent arterial bypass surgery (n=84) and group 2 with conservative management of exercise and medication (n=61). in case of significant iliac arterial stenosis, balloon angioplasty or ??stent insertion were added in both groups (17 in group 1, 16 in group 2). Changing of clinical manifeststaion and ankle-brachial index, claudication distance, rate of major amputation and mortality were compared between groups.
Result: There was a big difference in the rate of improving claudication distance at the end of one year after treatment (86.5% in group 1 ??vs 40.4% in group 2) but 5.4% of group 1 and 32.0% of group 2 showed aggravation of the symptoms. improved ankle-brachial index (ABI) noted in 88.1% of group 1 but in group 2, 39.3% showed increasing of ABI only under the conservative management. the proximal inflow procedure had more significant effect in improving ischemic sysmptoms and ABI in group 2 compare to group 1. One fourth of group 1 and 18.2% of group 2 showed spontaneous healing of their toe gangrene but 3.1% of group 1 and 54.5% of group 2 needed major amputation because of disease progress. New gangrene developed during their follow up and this also ended with major amputation in group 2. The difference of mortality rate between groups might be due to old age and associated cardiac disease.
Conclusion: Better results in improving ischemic symptoms and ABI with low rate of amputation and mortality encourage us to do an aggressive surgery. But significant portion of conservative group especially in patients with inflow procedures also showed improving symptoms, and this suggest us a need of significant consideration of medical and exercise treatment in selected cases.
