[Possibilities and limits of interventional therapy in chronic peripheral arterial occlusive disease].
In the therapy of the chronic peripheral vascular occlusion, angioplasty is rarely used to treat the infra-renal aortic stenosis, whereas the stenosis and the short occlusion of the iliac artery is a classical indication. Primarily, stenoses and occlusions of the iliac artery should be treated with balloon angioplasty exclusively. Only secondarily, when the result of angioplasty was insufficient, e.g. remaining stenosis or dissection, stent implantation is appropriate. Angioplasty is most frequently applied in the obliteration of the femoro-popliteal artery. It can be stated that early- and long-term results are the better, the shorter the occlusion is. Stent implantation in the femoro-popliteal artery should be avoided because of poor results. Only with the intention of limb salvage, when there is no opportunity for surgical treatment, a stent implantation should be considered. In case of recurrent stenoses after stent implantation, angioplasty can be reapplied with great success. The indication for any vascular intervention should be a decision of both, the interventional radiologist and the vascular surgeon, because both kinds of treatment are palliative and not causal. It is the task of the angiologist to do clinical diagnostics and the after-treatment. Quality monitoring is indispensable. It consists of documentation of pre-angioplasty diagnostics and should be able to prove the correct indication for the intervention. The result of the intervention should also be documented by angiography and functional tests. Regular control of the patient after the intervention is necessary for the early recognition of recurrent stenoses.
