PurposeAlthough thrombolysis obliterans (TAO) has been recognized for more than a century, there is no optimal treatment for this disease. The aim of this report was to compare the short-term efficacies of catheter-directed thrombolysis (CDT), percutaneous transluminal angioplasty (PTA) and CDT+PTA in treating TAO disease.MethodConsecutive patients with TAO treated at Ganzhou People's Hospital between 2012 and 2022 were included in this retrospective study. According to the information provided in the medical records, endovascular procedures included CDT, PTA or CDT+PTA. One-year follow-up outcomes of the patients with TAO who underwent endovascular procedures were compared. The primary outcome was major adverse limb event (MALE) and the secondary outcomes were the technical success, complications, ABI at 1 week after surgery and minor amputation.ResultsSixty-nine patients with TAO were assessed for inclusion in our single-center study from 2012 to 2022 and received endovascular procedures. Among them, 22 patients underwent CDT, 21 patients underwent PTA, and 26 patients underwent PTA+CDT. The one-year follow-up revealed significant differences in the MALE-free survival rates among the three groups, particularly between the CDT group and the PTA+CDT group (the hazard ratio (HR) for MALE-free survival was 0.173, 95% CI [0.050-0.599], p = 0.006). The technical success rates of the three groups were 63.6%, 90.5%, and 92.3%, respectively. There were differences in the ABI at one week after surgery among the three groups.ConclusionsEndovascular procedures are effective for TAO in the short term. The effectiveness of CDT alone is suboptimal; combining CDT with PTA achieves the most favorable endovascular treatment outcome; while the effectiveness of PTA falls in between these two procedures.
