Purpose
We review indications, proper vessel preparation, and optimal placement of the Supera peripheral stent system (Abbott Laboratories, Abbott Park, IL). Tips for deploying this unique stent will be discussed.
Materials & Methods
Endovascular treatment of peripheral arterial disease (PAD) affecting the superficial femoral (SFA) and popliteal arteries has long been a challenge for interventionalists as these arteries are prone to heavily calcified, long segment disease or occlusion. Additionally, the distal SFA and popliteal artery are exposed to compression, bending, and stretching forces during daily activities which make stents placed in this region at risk for fracture and subsequent restenosis of the artery.
Results
The Supera peripheral stent is a self-expanding Nitinol stent. Its interwoven wire construction provides increased radial strength, flexibility, and resistance to kinking and fractures - factors which are key for use in the SFA and popliteal artery across the knee joint. Appropriate stent sizing, predilation of the vessel, and deployment at the nominal length are important to maintain stent patency. Further, the Supera deployment system's unique design first releases the distal end of the stent to contact the vessel and then the stent is deployed as the delivery catheter is moved proximally which allows for stacking of the stent as needed. Illustrative cases, techniques, tips and pitfalls of sizing, deploying, and stacking the Supera stent will be presented.
Conclusions
Atherosclerotic disease involving the SFA and popliteal arteries can be difficult to treat. The Supera stent has unique qualities with promising results in terms of patency and resistance to fracture when deployed appropriately in this challenging anatomic region.
