Abstract
Evaluation o(percutaneous transluminal balloon angioplastv with or without stenting in treatment o(chronic peripheral arterial disease ofthe lower extremities.
The iliac and superficial femoral arteries are common sites of involvement of peripheral atherosclerotic disease. The lesions are typically long and the clinical presentation is diverse. Invasive methods of treatment (Per-cutaneous or surgical revascularization) should be reserved for patients with lifestyle disabling claudication, ischemic rest pain or non-healing ischemic ulcers and gangrene.
Percutaneous trans-luminal angioplasty with or without the use of stents, is the treatment of choice in the management of stenosis or total occlusion of iliac and femoral arteries.
We consider that endovascular management has many advantages such as low morbidity and mortality, acceptable long term patency rate, short hospital stay, can be repeated whenever indicated and the main advantage of endovascular therapy is that it does not exclude surgical revascularization.
All our patients were subjected to through history, detailed examination, laboratory investigations to determine the risk factors of the disease and to evaluate the fitness of our patients to the procedure and duplex scan, angiography were done to localize the lesions and to assess the distal run off.
In our thesis, we studied and analyzed 40 patients complaining of symptoms of chronic atherosclerotic occlusive disease of the lower
extremities, patients were classified into two groups : Stenotic group included 16 patients with arterial stenosis> 50% and shorter than 12 cm in length and group II included 24 patients with complete occlusion with maximal length 12cm .
In our study; segmental classification of the lesions were 10 cases with iliac lesions, 14 cases with femoro-popliteal lesions and 16 cases with tibial lesions.
In our study, the route of intervention was ipsilateral In 29 cases and contra lateral in 11 cases.
We used color duplex for follow up of all patients in this study, and we found that Ankle peak systolic velocity is a parameter with several advantages: it can be measured during routine duplex scanning of the arterial tree without any significant extra time, effort or cost.
We found that the success rate for the stenosis group was 100% and in the occlusion group it was 91.6% , primary patency rate at one year duration was 85.7% and 79.1 % for both groups respectively and we found marked improvement in signs and symptoms of both groups.
We found that the success rate for the iliac group was 100% and in the femoro-popliteal group it was 100% and at the tibial group was 91.6%. The primary patency rate at one year duration in il iac group was 90% and at the femro-popliteal group was 85.7% and at the tibial group was 75%.
