Thrombospondin-1 is a matricellular protein involved in the vascular injury response. Statins are cholesterol lowering drugs that have beneficial cardiovascular effects. Statis have been shown to inhibit smooth muscle migration through the mevalonate pathway. This effect is thought to be mediated by small G protein Ras and Rho turnover which requires many hours. While many patients undergoing treatment for vascular disease are on statins, many are not. Thus immediate pretreatment with statins before surgery may be beneficial. We hypothesized that statins have effects independent of the mevalonate pathway and thus have an immediate effect.</p><p><strong>Methods: </strong>Human vascular smooth muscle cells were pretreated for 20 h (long-term) or 20 min (short-term) with fluvastatin, or mevalonolactone plus fluvastatin.

Only patients who are referred for EVT will be recruited. The primary outcomes are immediate technical success, immediate technical failure, and 1-year limb base patency. The secondary outcomes are major adverse limb events, major lower limb amputation, and OS in patients presenting with CLTI who undergo EVT up to 1 year after the procedure.
