Infrared Imaging in Complex Regional Pain Syndrome

This research proposal aims to investigate the potential use of Infrared (FLIR) imaging to monitor the successful achievement of the sympathetic blockade in patients with complex regional pain syndrome (CRPS).

Inclusion Criteria:The patient is between 18 and 85 years oldProviding CRPS diagnostic criteria by using Budapest Clinical criteria [16]The patient has had pain and other symptoms for more than 3 monthsNot responding to conventional medical treatments and multidisciplinary approachHigh NRS detection in pain assessment despite appropriate treatment (NRS = and > 6/10).Pain is a limitation in the patient's functional capacity despite appropriate treatment.Exclusion Criteria:Patients with suspected disc herniation, spinal stenosis, myelopathy, and suspected radiculopathy in detailed examinations and examinations (MRI, CT).Systemic or local infectionCoagulation disordersHistory of allergy to contrast materialMalignancyPregnancyUncontrollable medical and psychiatric conditionThe patients diagnosed with dysautonomia, sympathetic dysfunction (such as Raynaud disease or Buerger disease), sweating disorders (such as acquired idiopathic generalized anhidrosis), and patients on vasoactive drugs, the mechanism of action is directly on the vascular tone.
