RSD/CRPS produces true chronic pain in patients that exceeds all scales of pain measurement and results in some very unique physical changes to their body.
The true chronic pain found in RSD/CRPS patients has had a pathology that has been partially healed, but is causing continuous pain and invasive operations only add new sources of pain in these patients. However, advances made on researching nerve pain resolution may hold promise for RSD/CRPS patients in the future.
The Department of Neurological Surgery, Division of Radiation Oncology, Mayo Clinic College of Medicine, Rochester, Minnesota undertook a study to determine the short term and long term capabilities of PRGR to alleviate chronic nerve pain in patients suffering from extreme medical conditions. The physicians objective was to seek rapid and long lasting pain relief in the management of trigeminal neuralgia (TN) and Percutaneous retrogasserian glycerol rhizotomy (PRGR) offers distinct advantages over other available procedures.
The PRGR procedures were performed at the University of Pittsburgh in 2004 on 1174 patients with immediate or early complete pain relief occurring in 90% of patients. An initial report in which 112 patients were evaluated demonstrated 90% pain relief at 2 years, with 60% of this group attaining complete relief after PRGR alone and 23% requiring some additional albeit reduced drug therapy. A subsequent analysis of 376 patients with follow-up durations of up to 7 years found a long-term pain control rate of 85%.5 Sixty percent attained complete relief after glycerol rhizotomy alone, although in some patients repeated procedures were necessary. In a longer-term assessment continuing up to 11 years, investigators found long-lasting relief of pain in 77% of patients, with 55% discontinuing all medications and 22% requiring some drug usage.
In the management of the TN patients, their goals were rapid and long lasting pain relief, together with preservation of trigeminal nerve function. The PRGR technique offers distinct advantages over other percutaneous procedures. These include eliminating the need for intraoperative confirmatory sensory testing (patient cooperation is not necessary) or a radiofrequency generator. The patient simply need not “participate” during the procedure and thus can be more deeply anesthetized. Precise anatomical localization of the target is performed using intraoperative cisternography rather than asking the patient to describe radiofrequency-induced sensory changes. Glycerol is associated with a lower risk of facial sensory loss compared with either radiofrequency rhizotomy or balloon microcompression. This feature significantly reduces the risk of deafferentation pain. They believe that pain relief without significant sensory loss and without high surgical risk is possible for virtually all patients by using MVD, PRGR, or stereotactic radiosurgery, either alone or in combination. The choice of procedure is related to the factors of patient age, medical condition, symptom severity, and personal preference.
Their finding was that PRGR is an effective, low-morbidity surgical procedure in the management of true chronic nerve pain and is associated with prolonged efficacy. Now the question is can this procedure produce similar results for RSD/CRPS patients in managing their nerve pain and when will some research be undertaken to pursue an answer to that question?
