Venous thromboembolism is defined as a formation of a blood clot in a vein. A common location for the blood clot is the calf. These clots can break loose and travel to the lungs (pulmonary embolus); this can result in death. According to a large new study, infants born prematurely have an increased risk of venous thromboembolism through young adulthood. The study was published online on July 28 in the journal Pediatrics by researcher at Stanford University School of Medicine (Stanford California) and Lund University (Malmö, Sweden).
The study authors note that preterm birth has been associated with increased risk of venous thromboembolism in infancy; however, the longer-term risk is unknown. Therefore, they conducted a study to assess this association from birth through young adulthood.
