Surgery was performed in patients with
Raynaud's disease (primary Raynaud symptoms) or with Raynaud symptoms as part of the cervical rib/
scalenus-anticus syndrome (secondary Raynaud symptoms). In 13 arms with primary, and six with secondary Raynaud symptoms with trophic changes, the aim was extensive
sympathectomy. Good results, without
Horner's syndrome, were obtained with extensive postganglionic
sympathectomy. When the grey ramus T1 could not be identified, T2
ganglionectomy and extirpation of the grey rami C7 and C8 were performed with the same result. Extirpation of the grey ramus C6 was not mandatory for a good result. Extirpation of unidentified T1 rami resulted in permanent
Horner's syndrome in two of four patients. Cases of secondary Raynaud symptoms without trophic changes were divided into two equal groups, each of 18 arms. Combined neurovascular
decompression and partial
sympathectomy were performed in one group, and neurovascular
decompression only in the other. Partial
sympathectomy seemed to improve the results.
