IPG surgery refers to the procedure of implanting the Implantable Pulse Generator (IPG) for a Deep Brain Stimulation (DBS) system. The IPG is a crucial component, acting as the battery-powered device that delivers electrical pulses to the brain. This surgery is typically done after the DBS leads are already implanted.
Understanding the IPG and Its Role
The IPG, is akin to a pacemaker, and plays a central role in DBS therapy. It is connected to the DBS leads via extension wires and it generates the electrical signals that modulate brain activity. This controlled electrical stimulation can help alleviate symptoms in various neurological conditions.
The IPG Implantation Process:
| Stage | Description | Timing | Setting |
|---|---|---|---|
| 1 | DBS Leads are implanted, which are placed in specific target areas of the brain | Prior to IPG implantation | Operating Room |
| 2 | IPG and Extension Wires Implantation is performed | Generally 5-14 days after lead implantation, sometimes at the same time. | Outpatient surgery, under general anesthesia |
| 3 | Extension wires are connected from the leads to the IPG | During the IPG implantation | Operating Room |
Key Aspects of IPG Surgery:
- Timing: According to the reference, the IPG is implanted either during the same procedure as the DBS leads or, more commonly, in a separate procedure occurring 5-14 days after the lead implantation.
- Anesthesia: The procedure is performed under general anesthesia.
- Outpatient: It is typically an outpatient surgery, meaning patients usually return home on the same day.
- Connection: The IPG is connected to the implanted DBS leads through extension wires which are also implanted.
Why Separate Procedures?
Separating the lead and IPG implantation can offer multiple benefits. It allows a recovery period before the IPG surgery, may reduce the overall time under anesthesia in one session, and provides an opportunity to assess the effectiveness of the lead placement before permanently installing the IPG.
