Clinical Features
- Red, tender nodules over peripheral arteries

Evaluation
- Clinical criteria for diagnosis (noninvasive testing not necessary)
- History of smoking

- Absence of atherosclerotic risk factors
- Upper limb involvement
- Infrapopliteal arterial occlusive lesions
Management
- Abstinence from tobacco
- Early symptoms with out threatened tissue loss: outpatient vascular
- Advanced disease: intra-arterial or intravenous PGE1, ASA, Heparin, arterial reconstruction, sympathectomy
Disposition
- Discharge with vascular follow-up if no evidence/threat of tissue loss
