He was referred to the vascular department by his primary care physician. He had stopped smoking for 6 months to treat thromboangiitis obliterans, but his symptoms were recurrent. The patient was interviewed about smoking in his living environment. His family members and his colleagues were smokers. Therefore, we advised to avoid secondhand smoke as well. Consequently, his symptoms resolved within 2 weeks. He had no relapse at follow-up after 6 months.
