My friend, I have been fortunate with scar tissue, I do have a lot of scar tissue in my L4 and L5 nerve root sleeves and due to repeat surgeries and fusion surgery in the 1990's (they used to just about crack you open) my low back is full of scar, when my physician placed the leads for the DRG under fluoroscopic guidance, he indicated it was just nothing but scar but he had no issues placing them appropriately. Strange that an SCS would leave a large amount of fibrosis (large amounts of hardened scar tissue) in your thoracic spine. Did you by chance have paddle leads installed? Percutaneous leads leave very little scar tissue in fact one of the major issues I have is that the leads move around far too much with positional changes. The new Medtronic system uses a closed loop system where in they sense a change in position and adjust stimulation accordingly. They also use multiple wavelengths to prevent the issue that many SCS patients have ... the body gets used to the signals and lose efficacy, typically starting around the 6 year mark. Depending on sources, up to 40% of SCS systems are removed by the 10 year mark due to this complication or lead migration. I highly recommend that all patients have both the trials and the installations done in a surgical center under strict fluoroscopic guidance. I am only 52 (I was seriously injured when I was 20) and having so many surgeries at a younger age, I am sure, helped prevent some of the complications that I now have with the surgeries in my 50's. I would highly encourage you to seek another opinion and then after that get another, as much as Philadelphia is a pain, I have been told by multiple surgeons that the A students are in Philadelphia, New York City etc. I went all the way to New York city for a tertiary opinion before having an additional decompression & fusion done at L3-4 due to adjacent segment disease. Was the severe scar tissue indicated in an MRI or CT Myelogram? As much as many of do not like to face it, the surgeon's skill is paramount as is the approach. Boston Scientific also has a top notch open system SCS that alternates wavelengths. Was the 2nd stimulator approach attempted with percutaneous leads? Given their small footprint they rarely leave large amounts of scarring and you may be able to get a better result with lead placement. Get another opinion brother there are doctors that specialize in almost nothing but stimulator implants.
