The effect of screening for deep vein thrombosis on the prevalence of pulmonary embolism in patients with fractures of the pelvis or acetabulum: a review of 973 patients.

Objectives: In patients with pelvic or acetabular fractures, to compare the prevalence of pulmonary embolism in a time period without screening for deep vein thrombosis to that seen when a screening protocol was in place.

Design: Retrospective.

Setting: County hospital.

Three-dimensional sonographic evaluation of the common bile duct.

Objective: To assess the accuracy of three-dimensional sonographic measurements of the common bile duct compared with standard two-dimensional anteroposterior measurement of the common duct.

Methods: Fifty-five consecutive patients referred for abdominal sonography underwent standard two-dimensional abdominal sonography followed by three-dimensional sonographic data acquisition of the right upper quadrant. A radiologist blinded to the results of the two-dimensional examination later measured the three-dimensional long axis anteroposterior common duct diameter and three-dimensional short axis anteroposterior and transverse common duct diameters.

Pelvic ring disruptions: prediction of associated injuries, transfusion requirement, pelvic arteriography, complications, and mortality.

Objective: To determine if age, fracture pattern, systolic blood pressure on arrival, base deficit, or the Revised Trauma Score is predictive of mortality, transfusion requirements, use of pelvic arteriography, later complications, or injuries associated with the pelvic ring disruption.

Study Design: Retrospective review of a prospectively collected database.

Methods: All closed pelvic ring disruptions seen between November 1, 1997 and November 30, 1999 were included.
