BACKGROUND: Although surgery for the treatment of @entity4553 is frequently performed, the exact rate of deep vein @entity715 following this procedure is unknown. We performed a single-center, prospective, phlebographically controlled study to quantify the rate of @entity49 following operative correction of @entity4553 . METHODS: Consecutive @entity1 undergoing chevron bunionectomy for correction of @entity4553 were enrolled in the study. @entity1 with clinical or hematological risk factors for @entity49 were excluded. One hundred @entity1 with a mean age of 48.9 years were operated on and did not receive medical prophylaxis against @entity715 . All @entity1 were assessed with phlebography at a mean of twenty-nine days postoperatively. RESULTS: @entity49 was found in four @entity1 (4%). The mean age of these @entity1 (and standard deviation) was 61.7 +/- 6.1 years compared with a mean age of 48.4 +/- 13.9 years for the @entity1 in whom @entity715 did not develop (p = 0.034). CONCLUSIONS: @entity1 are at a low risk for @entity49 following surgical treatment of @entity4553 . The need for prophylaxis against @entity715 should be calculated individually for each @entity1 according to his or her known level of risk. Routine medical prophylaxis against @entity715 might be justified for @entity1 over the age of sixty years.
