Revascularization strategies in below the knee interventions.

Until recently the role of endovascular revascularization in the infrapopliteal arteries was limited. Endo-vascular management including percutaneous transluminal angioplasty and subintimal angioplasty is now being considered as a primary alternative in critical limb ischaemia revascularization with a decreasing number of major amputations (above the ankle) performed. Endovascular treatment has been shown to have reduced morbidity and hospital stay compared to revascularization surgery with greater cost-effectiveness and better patient quality of life compared with major amputation.
