Introduction: Thromboangiitis obliterans or Buerger's disease is a non-atherosclerotic, segmental and inflammatory vaso‐occlusive disease that appears mainly in medium and small sized arteries. Clinically, the most common manifestations are consistent with symptoms of ischemia of the lower extremities, intermittent claudication is the earliest onset sign [3]. An arteriography may be performed as a follow-up method in patients with long-standing disease and persistent symptomatology. With technological development, CO2 arteriography, approved by the FDA, has become an alternative to that performed with iodinated contrast, especially in patients hypersensitive to iodine or with compromised renal function as in our patient [6, 7]. Clinical case: A 62-year-old patient with a personal history of arterial hypertension, stage III renal disease and Thromboangiitis obliterans for 20 years. The patient comes to the control of his disease with symptoms characterized by intermittent claudication with a distance of 200 meters in the left lower limb. He continues with his smoking habit and states that he does not plan to stop. On physical examination, palpation of proximal pulses is normal, distal pulses are not palpable, but they are audible with sound Doppler in both extremities. Due to the progressive deterioration of vascular symptomatology, it was decided to perform an arteriography. Due to the reported allergy and renal pathology, CO2 arteriography was chosen, a procedure that was performed without complications. With the arteriographic findings, without the presence of stenosis requiring revascularization, it was decided to continue with the clinical treatment of the pathology and insisting on the elimination of the smoking habit. Conclusions: Treatment of Thromboangiitis Obliterans consists of eliminating the smoking habit; however, in patients who cannot meet this criterion due to different circumstances, periodic follow-up is recommended to determine if there is .......
