@entity6323 @entity1 @entity157 @entity3181
@entity6323 ( @entity3181 ) is a rare cause of @entity3181 . When compared to the West, the incidence of @entity3181 was reported to be higher in the Orient, India and South Africa. From 1979 to 1993, 16 consecutive Chinese @entity1 (mean age 50 years) with @entity3181 were retrospectively evaluated. The diagnosis in these @entity3181 @entity1 was usually delayed with a mean lag time of 111 months. Most of the cases were detected by a delicate ultrasonographic examination of the abdomen. Segmental narrowing of the inferior vena cava in 11 @entity1 was the predominant type of @entity3181 , while five experienced a membranous obstructive type. Only one of five surgery-treated @entity1 had a post-operation survival > 5 years, while five out of the nine @entity1 who received conservative treatment still survived after a 6-15 year follow up. Two @entity1 received percutaneous angioplasty (PTA). One survived 4 years and the other expired 5 years after the PTA. Two @entity1 (12%) developed a @entity157 in their disease course, and the incidence was lower than in previous reports from Japan and South Africa. The incidence of hepatitis B surface antigen in @entity3181 did not increase in our @entity1 compared with the general population. In conclusion, the inferior vena cava should be carefully evaluated in an ultrasonographic examination of the abdomen to increase the diagnosis rate of @entity3181 . Surgical intervention should be carefully justified according to the @entity1 's symptoms and signs, the types of obstructive lesions and the expertise of the surgeons.
