[Unusual reason for unilateral (corrected) Raynaud's phenomenon with intensification when the arms are elevated].
Thoracic outlet syndrome (TOS) is a broad term for compression of the neurovascular structures in the area of the 1. rib and the clavicle. The cause can be either fibrous bands, cervical ribs, anomalous muscles or posttraumatic changes as well as tumors. Symptoms depend on the affected structure, in most cases (up to 97% of TOS patients) neurologic symptoms are present. In case of an arterial compression, for example due to a cervical rib like in our case, embolism of the arm and finger arteries can occur. For mild or moderate symptoms a conservative approach with physiotherapy can be helpful. For severe cases surgical resection of the compressing structure and the first rib is necessary. In our case, the cervical and first rib were excised after an initial lysis therapy. Furthermore, the aneurysm of the subclavian artery was excised.
