The 1-year results of the Ovation Abdominal Stent Graft System demonstrate excellent safety and effectiveness in treatment of patients with AAAs, particularly in patients with challenging anatomic characteristics, including short aortic necks and narrow iliac arteries. Longer-term follow-up is needed.
Options for lower limb percutaneous revascularization are limited especially for complex vessel obstruction. Cutting balloon angioplasty (CBA) has been described in the coronary literature as effective for complex disease. We analyzed our peripheral vascular database and report procedural outcomes along with the clinical success at a mean of 1-year follow-up in 73 patients with symptomatic lower limb ischemia undergoing CBA. CBA was successfully completed in all 73 patients (93 vessels; 100%) with predilation necessary in 4% of vessels. Severe intimal dissection or inadequate hemodynamic result necessitated in adjunctive stenting in 20%. There were no incidents of vessel perforation or surgical target vessel revascularization. One patient (1.5%) died during the periprocedural period due to renal failure. After mean follow-up of 1 year (6-21 months), 89.5% of threatened limbs were salvaged. CBA is a safe and feasible option for the treatment of popliteal and infrapopliteal vessels.
Retrograde tibial access can be a valuable technique in the armamentarium of a peripheral interventionist treating patients with chronic critical limb ischemia.
The strategy of excimer laser atherectomy and PTA followed by implantation of a self-expanding stent graft for the treatment of femoropopliteal ISR is safe and associated with high procedural success. Primary patency rate at 12-months was suboptimal; however, the TLR rate was low.
Percutaneous treatment of thrombotic occlusions with RT, followed by definitive treatment of the underlying stenosis, is a promising therapeutic option for patients with limb-threatening ischemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
