OBJECTIVE: To analyze the complications of diagnostic and therapeutic sonographically guided interventional procedures of focal liver lesions observed during a 22-year period in a single center. METHODS: Complications of sonographically guided diagnostic and therapeutic procedures on focal liver lesions, observed during a 22-year period in a single center, were reviewed. From 1979 to 2001, 13,222 patients (age range, 7-89 years; mean, 59 years; 8,688 male and 4,534 female) with 13,777 focal liver lesions underwent 16,648 sonographically guided biopsies and 3,035 therapeutic procedures: pyogenic and amebic abscess aspiration, ethanol injection of hydatid liver cysts, and percutaneous ablative treatments (ethanol injection in either multiple or one-shot sessions, radio frequency ablation, and interstitial laser photocoagulation) of primary and secondary liver tumors. RESULTS: The overall mortality was 0.06%. No death or major complication occurred after diagnostic procedures and liver abscess drainage. In the therapeutic group mortality was 0.6%: 1 patient died of anaphylactic shock during treatment of a hydatid cyst; 7 patients died after liver tumor ablation with ethanol injection (6 after one-shot treatments and 1 after multisession treatments). Major complications after liver tumor ablative procedures included 10 cases of acute liver failure, 2 cases of acute tubular necrosis, 2 cases of self-limiting hemoperitoneum, 2 cases of paralytic ileum, 2 abscesses, and 1 case of cholangitis. One case of a biliary cyst fistula and 1 case of intracystic hemorrhage occurred after treatment of hydatid liver cysts. CONCLUSIONS: Sonographically guided diagnostic biopsy of focal liver lesions and liver abscess drainage are safe procedures. In contrast, liver tumor ablation procedures have a low but definite risk of mortality and major complications. Puncture of hydatid cysts must be performed only in institutions that can treat anaphylactic shock.
