Abstract:

BACKGROUND: The assessment for long-term efficacy of chronic ischemic disease is more important than the short-term efficacy assessment, which associates with patient’s long-term quality of life and long-term survival rate.
OBJECTIVE: To observe the 5-year follow-up outcomes of autologous bone marrow stem cell transplantation for the treatment of thromboangiitis obliterans.
METHODS: This study enrolled 43 patients of thromboangiitis obliterans who underwent autologous bone marrow stem cell transplantation from August 2007 to January 2010 in the Department of Thyroid Vascular Surgery, the First Affiliated Hospital of Xinjiang Medical University. At 1, 2, 3, 4 and 5 years after transplantation, pain, cold sensation, and intermittent claudication distance were followed up by telephone; changes in limb ulcers were observed. At 1 year after transplantation, venous oxygen partial pressure and oxygen saturation of limbs were reviewed.
RESULTS AND CONCLUSION: A total of 38 thromboangiitis obliterans patients with complete follow-up data were included in the final analysis. Compared to the preoperation, pain, cold sensation, and intermittent 
claudication significantly improved. The difference was statistically significant (Z values: -4.277, -5.086, -3.574,
P < 0.001). Compared with 1-5 years after operation, pain and cold sensation had no statistically difference (P > 0.05). Intermittent claudication distance had increased. Differences in terms of intermittent claudication distance was statistically significant (Z=43.898, P < 0.001). Significant differences in venous oxygen partial pressure and oxygen saturation were detected between preoperation and 1-year posttransplantation (t values: 36.790, 43.964, P values: 0.040, 0.037). Above results suggest that autologous bone marrow stem cell transplantation for thromboangiitis obliterans obtained stable long-term outcomes.
