Background: Peripheral vascular diseases (PVDs) associated with atherosclerosis, hypertension, diabetes, thromboembolism,
chronic regional pain syndrome or Berger’s disease, presents with ischemic manifestations of cold limbs, claudication, ulcers, or
gangrene. Chemical lumbar sympathetic block (LSGB) with alcohol/ phenol and radiofrequency ablation (RF) are well-established
methods to improve the circulation.
Methods: We conducted prospective observational study in 150 cases of PVDs who underwent chemical LSGB using 5ml of
phenol 8% at two levels L2 and L3 under guidance of fluoroscopy (Group CH, n=50), RF ablation of lumbar sympathetic ganglions at
L2 and L3 level (Group RF, n=50) and combined RF with chemical LSGB using phenol 5ml 8% at L2and L3level following RF(Group
Results: There was significant difference i..... ReadMore
