POST-PROCEDURE
CARE
  • Patients should remain in bed for 2 to 6 hours to prevent bleeding at femoral access sites and should refrain from significant physical activity for 5 to 14 days after the procedure.
  • Patients should be cautioned to watch for swelling and bleeding at the femoral puncture site and to report these immediately to the nursing staff.
  • Patients who take metformin should be advised not to resume taking the medication for at least 48 hours after the procedure.
