Percutaneous dilatation of lower leg arteries
Insights
Percutaneous transluminal angioplasty effectively treated leg arteriosclerosis in 43 patients. Angioplasty achieved high success rates for stenoses and occlusions, improving limb salvage and claudication outcomes.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Leg arteriosclerosis significantly impacts patient mobility and quality of life.
- Percutaneous transluminal angioplasty (PTA) offers a minimally invasive treatment option for peripheral artery disease.
Purpose of the Study:
- To evaluate the initial outcomes of percutaneous transluminal angioplasty for leg arteriosclerosis.
- To assess the technical success and patency rates of PTA in various leg artery lesions.
Main Methods:
- Retrospective analysis of 43 patients treated with PTA between 1981 and 1982.
- Treatment of 45 lesions including iliac stenoses, femoropopliteal stenoses, and femoropopliteal occlusions.
- Assessment of technical success, one-year cumulative patency, and the impact of diabetes.
Main Results:
- High technical success rates were achieved for all stenoses and 63% of femoropopliteal occlusions.
- One-year cumulative patency rates were 81% for iliac stenoses, 66% for femoropopliteal stenoses, and 50% for femoropopliteal occlusions.
- Diabetes adversely affected outcomes, with significantly higher patency rates in non-diabetic patients.
Conclusions:
- PTA is a technically successful treatment for leg arteriosclerosis, including complex lesions.
- Angioplasty demonstrates promising one-year patency rates, offering limb salvage and claudication relief.
- Diabetic status is a critical factor influencing PTA outcomes and should be considered in patient selection and management.
Abstract:
Percutaneous transluminal angioplasty was introduced in the X-ray department of the Central Hospital of Etel ä- Pohjanmaa in 1981 for the treatment of arteriosclerosis of the leg. The first year material consisted of 43 patients. Of the 45 lesions treated 16 were iliac stenoses, 12 femoropopliteal stenoses, 16 femoropopliteal occlusions, and one occlusion of the deep femoral artery. In 20 cases, angioplasty was performed for limb salvage from amputation, in 23 because of claudication. Technical success was achieved in every stenosis and in 10 out of the 16 femoropopliteal occlusions (63 per cent). One year cumulative patency rate was 81% in iliac stenoses, 66% in femoropopliteal stenoses, and 50% in femoropopliteal occlusions. Diabetes had an adverse effect on the results. Excluding patients with diabetes, the corresponding figures were 88%, 89%, and 60% respectively.
