Abstract   Raynaud's phenomenon is a symptom complex manifested as intermittent fingertip ischemia caused by cold or other sympathetic drivers. Secondary Raynaud's phenomenon is often more severe and could even lead to finger ulceration, making it particularly complicated to treat. We describe a case of severe Raynaud's phenomenon secondary to subclinical hypothyroidism lasting for more than 6 hours in a mid-60-year- old woman. The patient was also diagnosed with hypothyroidism, epilepsy, and secondary soft tissue infection of the right middle and ring fingers. After careful multidisciplinary consultation and discussion, the patient received vasodilation, anticoagulation, thyroxine supplementation, stellate ganglion block, hyperbaric oxygen therapy and debridement. Finally, the female patient responded well, avoiding amputation or obviously dysfunction. Multidisciplinary team  gathering the doctors from different departments may propose an appropriate strategy for patients with severe Raynaud's phenomenon  and could improve the prognosis and satisfaction of patient effectively.

Key words: secondary Raynaud's phenomenon, multidisciplinary; stellate ganglion block
