OBJECTIVE: To analyze the complications of diagnostic and therapeutic sonographically guided interventional procedures of focal @entity409 observed during a 22-year period in a single center. METHODS: Complications of sonographically guided diagnostic and therapeutic procedures on focal @entity409 , observed during a 22-year period in a single center, were reviewed. From 1979 to 2001, 13,222 @entity1 (age range, 7-89 years; mean, 59 years; 8,688 male and 4,534 female) with 13,777 focal @entity409 underwent 16,648 sonographically guided biopsies and 3,035 therapeutic procedures: pyogenic and amebic abscess aspiration, @entity1068 injection of hydatid liver cysts, and percutaneous ablative treatments ( @entity1068 injection in either multiple or one-shot sessions, radio frequency ablation, and interstitial laser photocoagulation) of primary and secondary @entity96 . RESULTS: The overall mortality was 0.06%. No @entity204 or major complication occurred after diagnostic procedures and @entity5572 . In the therapeutic group mortality was 0.6%: 1 @entity1 died of anaphylactic shock during treatment of a hydatid cyst; 7 @entity1 died after @entity96 ablation with @entity1068 injection (6 after one-shot treatments and 1 after multisession treatments). Major complications after @entity96 ablative procedures included 10 cases of @entity879 , 2 cases of @entity4295 , 2 cases of self-limiting hemoperitoneum, 2 cases of paralytic ileum, 2 abscesses, and 1 case of @entity255 . One case of a @entity3116 and 1 case of intracystic @entity548 occurred after treatment of hydatid liver cysts. CONCLUSIONS: Sonographically guided diagnostic biopsy of focal @entity409 and @entity5572 are safe procedures. In contrast, @entity96 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.
