Risk factors and prevention of early infection after implantation or revision of transjugular intrahepatic portosystemic shunts: results of a randomized study.

The aim of this study was to evaluate the efficacy of a single dose of a second-generation cephalosporine to prevent postinterventional infection and to identify risk factors for postinterventional infection in patients receiving implantation or revision of a transjugular intrahepatic portosystemic shunt (TIPS). Eighty-four patients (105 transjugular interventions) were randomized receiving no antibiotic treatment (46 interventions) or 2 g cefotiam (56 interventions) given at the beginning of the procedure. Patients with overt infection or those receiving antibiotic treatment in the preceding two weeks were excluded. Groups were comparable with respect to biographic and medical data. Postinterventional infection was defined as an increase in WBC count (> or =15,000/microl), fever (> or =38.5 degrees C), or a positive blood culture. Infection occurred in 17% of the patients. Patients not receiving cefotiam had a slightly higher incidence of infection (20%) than patients treated with cefotiam (14%, NS). Multivariate analysis demonstrated prognostic relevance for multiple stenting and periprocedural use of a central venous line. The clinical outcome of the patients was unaffected by cefotiam treatment. In conclusion, a single dose of intrainterventional cefotiam does not prevent postinterventional infection. This may be due to the antimicrobial spectrum and short half-time of cefotiam. Strict adherence to aseptic conditions during intervention and early removal of central venous lines may reduce the rate of post interventional infection considerably. Antibiotic prophylaxis with cefotiam does not seem to be useful since it will not influence outcome and costs.
