Current Trends and outcomes: Endovascular Management in Arteriosclerosis Obliterans (ASO) of Lower Limb Vessels

Arteriosclerosis obliterans (ASO) or peripheral artery disease (PAD) is among one of the most common medical concerns that is responsible for high patient morbidity. Because of sedentary lifestyle and smoking ASO of lower limb vessels are now a considered with critical significance. Along with the different treatment method, the interventional procedure concerning Percutaneous Transluminal angioplasty (PTA) is the most successful procedure regarding the management of ASO of the lower limb vessels. The basic objective of this study is to determine the effect of PTA and compare the outcome of PTA -balloon dilatation with PTA stenting for the lesions of the lower limb vessels and to provide a proper conclusive indication of a particular management regarding endovascular management of lower limb vessel stenosis and osculation. Our study summarized with the following conclusion: PTA and primary stenting of the lower limb vessels for management of ASO can be performed safely in early and in advanced PAD. The results seem to be an improvement over those of balloon angioplasty alone when compared with published literatures. In the intermediate term, treatment of PAD by primary Implantation of a self-expanding stent yielded results that were superior to those with the currently recommended approach of balloon angioplasty. This reduces the chance of re-occlusion and thus reduces the morbidity and provides a better patient outcome. Judging the review of the literatures and the outcome, PTA appears to be the most feasible, safe, and effective procedure of these days for the treatment of ASO. In long-term results, most of the study data demonstrated a high success rate of PTA stenting in comparison to balloon angioplasty in the treatment of PAD cases. In the view of this it is justified to say that PTA can be the primary choice for the management of Critical limb ischemia.
