PURPOSE: @entity1151 ( @entity1151 ) are one of the major complications associated with total parenteral nutrition (TPN). Ventilation-perfusion scintigraphy (V/Q) remains the most used test for the diagnosis of @entity1151 and follow-up of @entity1 on TPN. The aim of our study was to demonstrate the high prevalence of undiagnosed @entity1151 in @entity1 on TPN. METHODS: The medical and imaging files of 64 @entity1 on TPN who underwent V/Q examinations covering the period of 1986-2004 were reviewed. @entity1 were aged between 3.18 months and 21.6 years. TPN was started at birth (range 0-15 years). All @entity1 had a normal chest radiograph and no symptoms at the time of the V/Q scan. A comparative analysis between the prevalence of @entity1151 and risk factors (number of days per week with lipophilic content of the TPN, bowel @entity32 and thrombophilic factors (protein C and S) was performed. RESULTS: Of the 64 @entity1 , 25 (39%) had an abnormal V/Q scan. A total of 29 @entity1151 episodes were diagnosed in all @entity1 . Two @entity1 had three episodes of @entity1151 . The median age at @entity1151 diagnosis was 4.6 years. In 17 @entity1 (68%) diagnosis was achieved on the first V/Q scan performed. @entity1151 was bilateral in 56% and unilateral in 44%. @entity1151 was the main cause of 2 out 15 recorded deaths. All risk factors were associated with an increase in @entity1151 prevalence by statistical analysis. CONCLUSION: @entity1151 is underdiagnosed in @entity1 on long-term TPN. Lung V/Q scintigraphy is useful in the diagnosis of @entity1151 in @entity1 with a low pretest probability.
