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 folow-up outcomes of autologous bone marrow stem cel transplantation for the treatment of thromboangitis obliterans. METHODS:This study enroled 43 patients of thromboangitis obliterans who underwent autologous bone marrow stem cel 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 folowed 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 thromboangitis obliterans patients with complete folow-up data were included in the final analysis. Compared to the preoperation, pain, cold sensation, and intermittent claudication significantly improved. The difference was statisticaly 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 statisticaly difference (P >0.05). Intermittent claudication distance had increased. Differences in terms of intermittent claudication distance was statisticaly 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 (tvalues: 36.790, 43.964,P values: 0.040, 0.037). Above results suggest that autologous bone marrow stem cel transplantation for thromboangitis obliterans obtained stable long-term outcomes.
