While surgical sympathectomy is an established treatment of Raynaud's phenomenon, its more invasive nature has prevented widespread application as an initial therapy. After introduction of minimally invasive surgical techniques in recent years, the investigators have further optimized the endoscopic sympathicotomy procedure performed on hyperhidrosis patients, now needing only a single 1 cm port for a detailed, panoramic view of the sympathetic chain (1). This minimal invasive technique has proven to be a safe, efficient and reproducible treatment for several indications and seems also suitable for Raynaud's patients.
