CT-GUIDED PERCUTANEOUS DRAINAGE OF RETROP ERITONEAL AND EXTRAPERITONEAL ABSCESSES AND FLUID COLLECTIONS

Purpose: Evaluation of course, success rate and complications after CT -guided percutaneous drainage of retroperitoneal and extraperitoneal a bscesses and fluid collections (PAFD). Methods: Retrospective review o f 47 PAFD in 42 consecutive patients (27 male, 15 female, age 58 [27-8 0] years) over a period of 7 years was performed. Results: 47 clinical ly suspected abscesses proved to be 40 abscesses, three haematomas and 4 lymphoceles. Primarily, 67 drainage catheters were needed, which in cluded three catheters in 4 patients and 4 catheters in one patient. D rainage time averaged 17.6 days (2-50). The most frequent drainage loc ation was the iliopsoas region (27/47 collections), The cure rate was 87.2% (41/47 collections). Temporization was achieved in 8.5% (4/47); there were two drainage failures (one sepsis, one recurrence). No majo r complications were observed, Three catheter dislocations occurred as minor complications. Conclusion: CT-guided percutaneous drainage of r etroperitoneal and extraperitoneal abscesses and fluid collections is safe, with a high cure rate and few complications.
