FLORES CANTISANI, J. A. et al. Neurolytic blocking third dorsal simpathetic ganglion in patients with Raynaud´s syndrome: A number of cases. Rev. Soc. Esp. Dolor [online]. 2013, vol.20, n.2, pp.50-54. ISSN 1134-8046.  https://dx.doi.org/10.4321/S1134-80462013000200003.

Background: Raynaud's phenomenon, a vascular disorder that is common in the general population, consists of paroxysmal onset distal vasospasm in small cutaneous arteries and arterioles of extremities, usually with little systemic impact. There are anatomical and physiological bases to produce a selective sympathetic block ad using neurolytic agents in the thoracic ganglia T2 and T3 considered synaptic stations that are distributed in the upper limb. Objective: The objective of this work was to determine the efficacy of neurolytic block of the third dorsal ganglion due to Raynaud's syndrome in a series of cases. Material and methods: A review of records of eight cases with Raynaud's phenomenon that presented multifactorial origin were conducted on Clinic of the Pain located in the Unidad Médica de Alta Especialidad, Monterrey Nuevo León, México. Cases: Eight patients from 41 to 72 years old were medically treated for Raynaud's phenomenon using sympathicolysis dorsal third node. Conclusions: Raynaud's phenomenon with a prevalence ranging from 1 to 25% has an increased sympathetic activity. The ischemic pain that is determined by total or partial failure in the oxygen transport to tissues was reduced in these patients by performing a selective sympathicolysis in the thoracic ganglia T2 and T3 considered synaptic stations that are distributed in the upper limb. It was demonstrated in this study that this treatment is selective with less adverse effects to the patients.
