Characteristics of XXXX associated with prolonged travel.

@entity1 @entity1150 @entity49 @entity715
OBJECTIVES: to identify the incidence of prolonged travel among consecutive @entity1 with @entity1150 ( @entity1150 ) and to investigate any differences in the patterns of traveller's @entity715 versus @entity1150 's with no history of prolonged recent travel. METHODS: of 137 consecutive @entity1 , who were confirmed to have @entity1150 by duplex ultrasonography, 36 were excluded because of either prolonged immobilisation or recent surgery. All @entity1 were asked whether they had travelled within 2 weeks for more than 3h. The presence of other classic risk factors for @entity1150 was also recorded. @entity1 who were unlikely to travel as a result of prolonged immobility for more than 2 weeks and those who underwent surgery within 2 weeks were excluded from the study. The extent and location of thrombi was also verified by duplex scanning in each @entity1 . RESULTS: of 101 @entity1 , eligible for the final analysis, 15 (15%) claimed to have a recent travel, of whom 9 (9%) travelled by air. By comparison of a group of 106 @entity1 with similar symptoms at presentation, but who had negative duplex finding 12 (11%) had a history of prolonged travel (p=0.8, Fisher's exact test). Travel-related @entity1150 occurred to a significantly younger age group than non travellers. Thirteen (87%) out of 15 @entity1 with travel-related @entity1150 had another coexisting risk factor and 7 out of 10 @entity1 had a positive @entity49 screen. CONCLUSION: The majority of those with travel-related @entity1150 had other concomitant risk factors and a high incidence of a positive @entity49 screen, suggesting that travel itself may act as an additive risk among those with pre-existing risk factors for @entity1150 .
