hemostasis
Pronunciation: /hiːˈmoʊstəsɪs/
Achievement of bleeding control at vascular access sites following catheter removal after endovascular procedures.
Full Definition
Hemostasis in the angiologic context refers to the successful cessation of bleeding from arterial or venous access sites after completion of catheter-based interventions. This critical procedural endpoint involves the body's natural clotting mechanisms combined with external compression or closure device deployment. Methods include manual compression, mechanical compression devices, or vascular closure devices such as collagen plugs or suture-based systems. Adequate hemostasis is essential to prevent access site complications including hematoma formation, retroperitoneal bleeding, or pseudoaneurysm development. Time to hemostasis and method used are important quality metrics for interventional procedures.
Usage
Usage note: Note the medical spelling with 'e' rather than the variant 'haemostasis' in contemporary vascular literature.
