[Arteriosclerosis obliterans that was improved by LDL apheresis].
We reported here a case of arteriosclerosis obliterans (ASO) in which clinical symptoms and signs were improved after repeated LDL apheresis. The patient was a 70-year-old man who was diagnosed as having ASO in 1989. Although drug treatment started for the arterial disease, such clinical manifestations as rubor and intermittent claudication were gradually worsening. In 1991, the patient was also found to have diabetes mellitus (DM), leading to admission for its treatment. Insulin therapy was initially required, but it finally became possible to maintain a good control of DM with diet therapy alone. Since hypercholesterolemia (402 mg/dl) was noted on admission, we began to give the patient pravastatin. In response to the medication, serum total cholesterol (TC) levels declined to 270 mg/dl, but no further improvement was obtained. We therefore decided to perform LDL apheresis on the patient, hoping the improvement of both ASO and hypercholesterolemia. After six series of LDL apheresis were performed during 4 weeks, ASO-related signs and symptoms (i. e., intermittent claudication) were remarkably improved, and serum TC levels were decreased below 200 mg/dl. Our experience in the present case suggested that this procedure would be useful as an effective choice of treatment for ASO, but further studies as to the indication and protocol of this therapeutic maneuver will be clearly needed.
