[Indications and place of surgery in acrosyndromes of the hand with arteriolitis].

In acrosyndromes of the hand with lesions of the digital arteries, the surgical indication must first be based on an accurate etiological diagnosis. The identification of a high lesion, usually subclavian, with the potential of embolus will be an indication for a direct approach of the lesion at the subclavian level. In case of isolated digital arteritis, secondary to a Raynaud's phenomenon or apparently primary, an operative indication must be kept in mind in case of trophic disorders and severe pain: thoracic sympathectomy gives usually in these cases very satisfactory results.
