During an aneurysm repair via coil procedure, what is the required activated clotting time (ACT)?

In the context of an aneurysm repair via coil procedure, maintaining an appropriate activated clotting time (ACT) is crucial for ensuring effective anticoagulation during endovascular interventions. The target ACT is often set to ensure that the risk of thrombus formation is minimized while also preventing excessive bleeding.

The recommended ACT of approximately 300 seconds is sufficient to achieve optimal anticoagulation for procedures such as coil embolization. This level of ACT helps in balancing the need for adequate blood clotting in the procedural site while minimizing the risks associated with thrombus formation in the vascular system due to the use of catheters and coils.

In clinical practice, monitoring the ACT allows interventional radiologists to adjust heparin administration to achieve this target, which is vital for the safety and success of the procedure. An ACT that is too low may increase the risk of clot formation, leading to complications, while a much higher ACT could lead to problematic bleeding.

Thus, a target ACT of around 300 seconds is established to facilitate safe and effective aneurysm coil repair, reflecting the concerns of maintaining hemostasis and preventing complications associated with these interventions.
