Abstract
To evaluate the usefulness and safety of endovascular treatments for acute upper limb ischemia (AULI) by using multiple techniques, and to compare catheter-directed thrombolysis (CDT) and percutaneous aspiration thromboembolectomy (PAT) as initial procedures. The study included 18 patients (4 men and 14 women) with AULI, who underwent a total of 20 sessions of endovascular treatment using various endovascular techniques between January 2005 and April 2016. The patients were initially treated with CDT [n=9, CDT-based group (C-G)], PAT [n=6, PAT-based group (P-G)], or angioplasty (n=3). In case of residual emboli, we performed additional endovascular techniques. We assessed technical success, clinical success, and complications. Additionally, we compared the urokinase dosage between the groups. The mean patient age was 74.4years. Technical and clinical success was obtained in all patients. Among the 18 patients, 1 underwent CDT only, 2 underwent PAT only, 1 underwent angioplasty only, and 14 underwent multiple techniques. Two patients from the C-G experienced major complications (cerebellar hemorrhage 1; pseudo-aneurysm in a branch of the ulnar artery 1). The mean urokinase dosage was lower in the P-G than in the C-G (40,000 vs. 246,667IU; Mann-Whitney U test, P=0.004). Endovascular treatment is effective and safe for AULI. A combination of multiple endovascular techniques is important for successful treatment. PAT is suggested as an initial procedure among endovascular techniques, in terms of a lower dosage of urokinase and a lower complication rate. IV, Case-control studies.
