OBJECTIVE: We reviewed the Mayo Clinic experience with management and outcome of @entity99 ( @entity99 ). METHODS: Retrospective review of charts for 306 @entity1 with true visceral @entity439 diagnosed from 1980 to 1998 enabled identification of 36 @entity1 (12%) with @entity99 . RESULTS: @entity1 with @entity99 included 23 @entity1 and 13 @entity1 , with mean age of 62.2 years (range, 20-85 years). Most @entity439 were extrahepatic (78%) and single (92%). Mean @entity439 diameter at presentation was 3.6 cm (range, 1.5-14 cm). Five @entity439 had @entity397 (14%), and four were symptomatic (11%). Mortality from @entity397 was 40%. Of the 9 @entity1 with @entity397 or symptomatic @entity439 , 2 @entity1 had multiple @entity99 , 3 @entity1 had @entity4267 , and 2 @entity1 had @entity573 nodosa. All five HAAs that @entity397 were of nonatherosclerotic origin (P =.001). Fourteen @entity1 (39%) underwent elective procedures, including excision with vein graft (n = 7), excision with dacron graft (n = 3), excision alone (n = 2), and percutaneous embolization (n = 2). Two vein grafts and one dacron graft became occluded within 1 year. Nonoperative management was elected in 22 @entity1 (61%) with mean @entity439 diameter 2.3 cm (range, 1.5-5 cm). No complications related to the @entity439 occurred during mean follow-up of 68.4 months (range, 1-372 months). @entity439 growth was identified in 27%, the greatest being 0.8 cm over 34 months. CONCLUSIONS: @entity99 are at definite risk for @entity397 (14%). Risk factors for @entity397 include multiple @entity99 and nonatherosclerotic origin. @entity1 with symptomatic @entity439 or any of these risk factors should be considered for intervention.
