Hepatic intraarterial antibiotic therapy for resistant hepatic abscesses.
Liver abscesses present a severe problematic medical entity. The traditional treatment modality consists of surgical drainage, which cannot be accomplished in all circumstances. Other modes of therapy include systemic antibiotics or percutaneous catheter drainage under ultrasonography or computerized tomography. Despite new treatment regimes liver abscesses, to date, are a potentially lethal disease, with a mortality rate of about 50%. We report an innovative approach of high dosage intrahepatic arterial antibiotic infusion for the therapy of hepatic abscesses, which are resistant to conventional treatments. A patient who underwent mastectomy for breast carcinoma, developed liver metastases one year later. She was prescribed systemic chemotherapy for one year, but no antitumor response was evident. Since ther was no evidence for extra-hepatic metastases, intraarterial hepatic chemotherapy was instituted, using an Infusaid (Mi-400) implantable pump. Marked regression of liver metastases was observed. Therapy was withheld after 19 months because of biliary sclerosis development. At this stage, the patient developed liver abscesses, which were resistant to systemic antibiotic therapy. Intraarterial antibiotic therapy, using the implantable pump, was initiated. Following the treatment, a marked improvement in the patients' clinical condition was recorded and shrinkage of the abscesses was evident by ultrasonography. The patient was free of symptoms for three months, when she was readmitted with evidence of terminal metastatic disease and sepsis. It is suggested that intrahepatic arterial antibiotic therapy is an additional mode of treatment for patients with persistent liver abscesses which fail to respond to conventional treatment.
