[Immediate hemostasis of the femoral artery after heart catheterization: the present situation of closure systems].
Review
Overview
abstract
The femoral approach is the most commonly used route for diagnostic cardiac catheterization and coronary interventions today. Manual compression and pressure bandages usually lead to immobilisation of the patient for several hours and may result in significant discomfort. Since the introduction of the first femoral closure device in 1991, many devices have proven their efficacy in significantly reducing time to hemostasis while simultaneously improving patient comfort. Twenty four closure device systems with different concepts are on the market, e. g. pure collagen, collagen + thrombin, collagen + anchor, vascular suture, hemostatic patches and pads, staples and more. The four predominantly used are Angio-Seal (46 %), Perclose (32 %), VasoSeal (14 %) and Duett (3 %). The effectiveness of all four systems has been proven in a prospective, randomized, controlled multicenter trial each. Efficacy and safety were analyzed using data from ten comparative studies in 8832 predominantly or exclusively interventional patients, however none of the closure systems proved to be superior. Fortunately, recent years have shown a trend toward a reduction in local complications by vascular closure devices compared to manual compression. Closure devices are thus becoming increasingly cost effective. Vascular closure systems should be preferred when the prolonged supine position is not tolerated, a protein IIb/IIIa-inhibitor was used during the procedure, or early discharge of patient is anticipated. In the presence of peripheral vascular disease, small diameter of the femoral vessels or stenotic lesions in the femoral artery, closure devices should be used with caution. Closure systems for immediate femoral puncture site hemostasis are now an important tool of invasive cardiology today.
