Vascular Access and Closure for Peripheral Arterial Intervention.

Peripheral arterial interventions require safe and effective vascular access and closure. The sites, techniques, and equipment used may vary depending on patient and procedural factors. To minimize the risk of procedural complications, arterial access should use micropuncture technique, ultrasound and fluoroscopic guidance, a compressible arterial access site, and the smallest diameter sheath necessary. Hemostasis at an arteriotomy site may be achieved by manual compression, device-mediated compression, an intravascular closure device, or an extravascular closure device. Although closure devices improve patient comfort and expedite hemostasis, they have not been shown to reduce complications in comparison with compression.
