Filter by:Objectives: 1) To evaluate the feasibility of using intravascular ultrasound to assess lesion morphology, select an appropriate stent size and landing zone 2) To compare the primary patency rates after intra vascular imaging-guided versus angiography-guided stent implantation for the treatment of fermoropopliteal artery segment lesions. Hypothesis: One of the key determinants of the device failure is inappropriate landing zone, selection of smaller stent relative to the reference vessel diameter, and lack of high-pressure post-dilatation in a necessary post-stent segment. Therefore, intravascular ultrasound-guided selection of appropriate landing zone, stent size and balloon size for high pressure post-dilation may maximize the benefits of stent use and improve patency duration. the investigators hypothesize that intravascular ultrasound-guided stent implantation is superior to angiography-guided stent implantation with respect to 12 months primary patency in patients with significant femoropopliteal disease
Intermittent Claudication (IC)is a common condition characterised by pain in the muscles of the legs on exertion caused by "hardening of the arteries" and a reduced blood supply. The investigators know that the vast majority of people suffering from this condition remain stable and do not deteriorate, and thus in general the viability of legs is not at risk. The main aim of treatment, therefore, is to try and improve walking thus reducing the impact this problem has on patients life style. There are many methods of management of intermittent claudication, but the investigators do not know which produces the best results. This study aims to compare the short and medium term outcomes of exercise programmes, percutaneous transluminal angioplasty and a combination of the two treatments for patients with intermittent claudication.
