Outcomes of Catheter Directed Thrombolysis for Early and Late Re-occlusions in Acute Lower Limb Ischemia

Catheter-directed thrombolysis (CDT) is a well-established treatment for acute lower limb ischemia (ALI). Re-occlusions after successful treatment are, however, observed in almost a third of the patients. Yet, the outcomes of CDT for re-occlusions for patients who were previously treated with CDT are not well known. This study showed that CDT is effective in achieving revascularization in cases of early and late re-occlusion after treatment for ALI, but the risk for further re-occlusions is high. Future studies should focus on maintaining patency after successful CDT for ALI.
