Abstract:
The implantation of a drug (opioid) infusion system catheter at the level of the cisterna magna, connected to an implanted programmable pump (Synchromed pump, 8611-H, Medtronic, Minneapolis, MN) is the procedure we use most commonly for the treatment of craniofacial and upper cervical pain. Our implantation technique, which we consider simple and easy to perform, is discussed in this article. Our results have been extremely encouraging, without untoward effects occurring. Adverse effects are prevented by the close proximity of the catheter tip to the pain receptors.
