Arterial Femoral Sheath Removal Procedure
Patient Preparation and Assessment
- The American Heart Association recommends verifying that coagulation parameters are appropriate before sheath removal, for patients who received heparin, wait until the activated clotting time (ACT) falls to 150-180 seconds or when the activated partial thromboplastin time falls to 50 seconds 1
- Position the patient supine with the affected leg straight and immobilized, and ensure proper monitoring equipment is in place, including blood pressure monitoring and pulse oximetry 2
- Consider placing an additional pulse oximeter on the foot of the affected leg to provide early warning of femoral artery obstruction or distal thromboembolism 2, 3
Equipment Preparation
- Gather necessary supplies, including sterile gloves, antiseptic solution, sterile gauze, compression device (if using), and appropriate dressings 2
- Ensure emergency equipment is readily available in case of complications 2
Sheath Removal Procedure
- Cleanse the puncture site with antiseptic solution 4
- Apply manual pressure 2-3 cm proximal to the puncture site 2, 5
- While maintaining proximal pressure, smoothly and steadily remove the sheath in a single motion along the angle of insertion 2
- Gradually reduce pressure while monitoring for bleeding 2
Post-Procedure Care
- Apply a sterile pressure dressing once hemostasis is achieved 2
- Monitor vital signs and puncture site frequently for the first hour, then periodically for 24 hours 4
- Assess distal pulses, color, temperature, and sensation of the affected limb regularly 2
- Monitor for complications including hematoma, pseudoaneurysm, retroperitoneal bleeding, and arteriovenous fistula 4
Special Considerations
- Small asymptomatic pseudoaneurysms (<2.0 cm) may resolve spontaneously within 2 months and can be managed conservatively with follow-up ultrasound 4
- Larger pseudoaneurysms (≥2.0 cm) that persist may require surgical intervention 4
Common Pitfalls and How to Avoid Them
- Overly vigorous compression causing vessel occlusion can be avoided by monitoring distal pulses during compression 2, 3
- Improper identification of puncture site can be avoided by using anatomical landmarks or ultrasound guidance to identify the common femoral artery 6
- Failure to recognize complications early can be avoided by maintaining vigilant monitoring of the access site and distal circulation 4
