[The percutaneous aspiration and drainage of infected fluid retention after organ transplantation]

Local postoperative infections in immunosuppressed patients carry a high mortality rate. In this group of patients interventional radiological procedures are particularly valuable in diagnosis and treatment. We report on the results of radiologically controlled aspirations (11 cases) and drainage (37 cases) of infected fluid collections in 47 patients following transplantation of various organs. By percutaneous aspiration or drainage, 91.7% of infected fluid collections were successfully treated or the clinical condition of the patient improved so that surgical intervention could be avoided. The causative organism was identified and antibiotic treatment carried out in 72.9% (35 cases). Surgical intervention was necessary in only 4.3% (2/48). Needle aspiration or drainage of percutaneously accessible fluid collections thought to be infected appears to be particularly useful for transplant patients at increased risk and is a good alternative to surgical treatment.
