• Choose a delivery catheter based on the size of the target vessel
and the microsphere size being used. EmboGold Microspheres can
tolerate temporary compression of up to 33% in order to facilitate
passage through the delivery catheter.
• EmboGold Microspheres are not radiopaque. It is recommended
that the embolization be monitored using fluoroscopic visualization
by adding the appropriate amount of contrast medium to the
physiologic saline suspension fluid.
• To deliver EmboGold Microspheres:
Match the total volume in the syringe with the same volume of
undiluted contrast, which will result in a 50% microsphere/saline
and 50% contrast solution. Remove all air from the syringe. To
evenly suspend the EmboGold Microsphere/contrast solution,
gently invert the 20mL syringe several times. Attach the 20mL
syringe to one port of the luer-lock 3-way stopcock; attach a 1mL
or 3mL injection syringe to another port on the stopcock, and, if
desired, a delivery catheter may be attached to the remaining port
on the stopcock. Wait several minutes to allow the EmboGold
Microspheres
to
suspend
properly.
Draw
EmboGold
Microsphere/contrast solution into the injection syringe slowly and
gently to minimize the potential of introducing air into the system.
Purge all air from the system prior to injection. Inject the EmboGold
Microsphere/ contrast solution under fluoroscopic visualization with
the injection syringe, using a slow pulsatile injection, while
observing the contrast flow rate. If there is no effect on the flow
rate, repeat the delivery process with additional injections of
EmboGold Microsphere/contrast solution, or larger sized EmboGold
Microspheres
may
be
considered.
If
the
EmboGold
Microsphere/contrast solution requires resuspension, gently invert
the 20mL syringe several times. Exercise conservative judgment in
determining the embolization endpoint.
• Femoral puncture can result in arterial spasm. This may
predispose to femoral thrombosis (e.g. leg injury). Femoral patency
should be re-assessed prior to final catheter removal.
• Upon completion of the treatment, remove the catheter while
maintaining gentle suction so as not to dislodge EmboGold
Microspheres still within the catheter lumen.
• Apply pressure to the puncture site until hemostatis is complete.
• Discard any open, unused EmboGold Microspheres.
