Abstract
An endovascular-first approach is recommended in the majority of femoropopliteal stenoses or occlusions, although vein bypass surgery still has a role in case of long or heavily calcified CTO and in patients with a favourable life-expectancy.
However, preservation of long-term patency remains a challenge, mainly due to progressive neointimal hyperplasia and vascular restenosis. The main factor adversely affecting patency outcomes seems to be the unique biomechanical properties of the femoropopliteal vascular segment.
Intraluminal or subintimal recanalization techniques may be used based on operator preference and experience.
Randomized, controlled trials have also shown marginally increased primary patency rates following primary nitinol stent placement.
All patients should receive dual antiplatelet therapy following a successful endovascular procedure.
So that project aims at recognition of different factors that may affect may the long run patecy of SFA after stent deployment .
1- Early intervention after good pre-operative evaluation is very important to gain optimum outcome.
2- Preoperative mapping to identify the nature and location of lesions: Doppler ultrasound and CT angiography or direct interventional angiography of the arteries of the lower limb should be done for all patients.
3- This study included 30 patients with affected 33 limbs ,ALL underwent PTA and having SFA stenting , this group of patients are claudicants and CLIs (presented with tissue loss , gangrene or rest pain) , according to Rutherford classification.
4- Many factors affect the outcome of this study we found that controlled diabetics , non smokers , good distal runoff ,type A &B lesions of SFA exhibited more successful rate.
5- Acquisition of experience of endovascular stuff , availability of endovascular equipments & proper imaging in angiography suite and post operative instructions and treatment is very important and play amajor and effective factors in the success of the endovascular procedures.
