RESUMO
Objective To investigate the method and curative effect of the CT-guided percutaneous catheter drainage in hepatic ab-scess.Methods 36 patients with liver abscess were treated with “one-step”percutaneous 8F pig tail catheter tube under CT guidance. Results 36 patients were performed “one-step”percutaneous catheter drainage,the successful rate was 100%,no severe complica-tions occurred.Symptoms were improved after cathetering in all patients.Of these 36 patients,30 patients had single abscess and 6 patients had multiple abscesses.The mean duration of drainage catheterization was 21.2 days for 36 patients.The diameter of ab-scess was between 4.0-1 9.5 cm,the mean diameter of abscess was 8.3 cm.Conclusion CT-guided percutaneous hepatic abscess catheter drainage is a safe,effective,minimally-invasive treatment.
