The objective of this study was to determine epidemiology and mortality statistics for @entity1028 ( @entity1028 ) in Hong Kong. Data from three sources were obtained and analyzed: (1) Hong Kong Hospital Authority discharge statistics for 1999 and 2000; (2) a survey on @entity449 in public hospitals conducted by the Working Group of Vascular Surgery; and (3) the Department of Surgery, University of Hong Kong Medical Center aortic @entity439 database. The disease pattern, distribution, and operative mortality were determined. The annual incidence of @entity11557 in Hong Kong is 13.7 per 100,000 population and 105 per 100,000 for those aged 65 and above. About 10% of the @entity1028 that presented were ruptured. The mean age of the @entity11557 @entity1 was 74 years, with 84% of them over age 65. The operative repair rate for @entity1028 was low, being only 8% for intact @entity439 and 54% for ruptured ones. Overall, 45% of all @entity439 repairs were performed for a @entity397 . There is diverse practice between major vascular centers and smaller regional hospitals. The territory-wide operative mortality rates for intact and @entity1756 were 10% (range 4-24%) and 70% (range 38--100%), respectively. There was no gender bias in the @entity397 and operative rates. The overall mortality was 17% for intact @entity1028 and 78% for ruptured @entity1028 . The average length of hospital stay was 19 days for elective @entity11557 surgery and 13 days for ruptured @entity1028 . The number of operations in high-volume centers is increasing with a concomitant decrease in operative mortality. There are no definitive data to indicate that the incidence of @entity1028 is rising, but a trend toward an increasing number of operations in referral centers is noted. The low repair rates for intact @entity1028 and the high proportion of repairs for @entity1756 suggest that @entity1028 are undertreated in Hong Kong.
