hemostasis
Pronunciation: HEE-moh-stay-sis
The process of stopping bleeding at vascular access sites following interventional procedures.
Full Definition
Hemostasis in vascular intervention refers to the achievement of bleeding control at arterial or venous puncture sites after catheter removal. This can be accomplished through manual compression, mechanical compression devices, vascular closure devices, or combinations of these methods. Adequate hemostasis is critical to prevent access site complications such as hematoma formation, pseudoaneurysm, arteriovenous fistula, or retroperitoneal bleeding. Factors affecting hemostasis include sheath size, anticoagulation status, patient anatomy, blood pressure, and procedural complexity. Modern vascular closure devices have reduced time to hemostasis and ambulation while maintaining safety compared to manual compression techniques.
Usage
Usage note: Distinguish from 'homeostasis' which refers to physiological balance rather than bleeding control.
