Percutaneous transcatheter renal artery thrombolysis for acute renal artery embolism：analysis of clinical efficacy / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical effect of percutaneous transcatheter renal artery thrombolysis in treating acute renal artery embolism. Methods A total of 23 patients with acute renal artery embolism underwent DSA-guided percutaneous transcatheter renal artery thrombolysis. Continuous urokinase thrombolytic therapy with micro pump was carried out in all patients; renal artery angiography was performed 3 days later; the therapeutic effect was evaluated with imaging manifestations and laboratory tests. Results Postoperative DSA showed that the renal artery was completely open in 21 patients and partially open in 2 patients; the effective rate was 91.3%. After thrombolysis treatment, complete remission of pain, oliguria, hematuria, fever and other symptoms was obtained in 21 cases, and relief of symptoms in 2 cases. Postoperative urine protein, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase isoenzyme MB (CK-MB) and serum creatinine (SCr) levels were obviously decreased. Conclusion For the treatment of acute renal artery embolism, DSA-guided percutaneous transcatheter renal artery thrombolysis is very effective, minimally-invasive and highly-safe.
