What is the maximum international normalization ratio (INR) that most interventional radiologists will accept before performing a procedure?

Interventional radiologists generally aim for a safe procedural environment, which includes assessing the patient’s coagulation status prior to intervention. The maximum international normalization ratio (INR) typically accepted is 1.6 or below. At an INR of 1.6, the risk of bleeding during and after procedures remains lower, significantly reducing the likelihood of hemorrhagic complications.

An INR above this threshold indicates a higher degree of anticoagulation, which could increase the risk of uncontrolled bleeding during the procedure. Thus, keeping the INR at or below 1.6 helps ensure that patients are at a safer level for such interventions. In practice, this threshold may vary slightly based on the specific procedure being performed, the patient's individual risk factors, and the clinical judgment of the interventional radiologist.

By adhering to this standard, practitioners can more effectively manage patient safety and procedural outcomes, highlighting the importance of maintaining a strict regimen regarding anticoagulation management before interventional procedures.
