Percutaneous arterial closure devices.
Advances in interventional angiography such as covered stent technology and adjunctive anticoagulation and antiplatelet therapy for arterial recanalization have reached the margins of percutaneous application. In these circumstances, compression methods of arterial closure require prolonged compression or long arterial sheath dwell times that increase procedural time, complication rates, and patient discomfort. Percutaneous arterial closure devices offer the potential of rapid hemostasis and shorter times to ambulation and discharge. These benefits have costs, in terms of the price of the devices and complications of their use. A Web search identified approved and pending devices. A Medline search identified device studies that were reviewed to assess the efficacy and complication rates of device-mediated closure versus the gold standard of manual compression. Studies that compared devices were evaluated to determine if any particular device was superior. The arterial closure devices were equivalent to manual compression in the establishment of hemostasis in the diagnostic population. However, complication rates were higher. In the therapeutic populations, the devices were as efficacious as manual compression, without correction of anticoagulation, and the complication rates were similar. No individual device was clearly superior.
