Deep Vein Thrombosis

The trial uses compression ultrasound rather than venography to diagnose DVT because venography is invasive, has potential side effects, and would be less acceptable for repeated procedures. DVT rates in hip-fracture patients are substantially higher than those seen in other fracture types, such as ankle fractures at 2.6% and bilateral calcaneus fractures at 8.1%. Preoperative DVT incidence in elderly hip-fracture patients ranges from 8% to 34.9%, with some studies reporting perioperative rates above 50%. The trial monitors DVT only during the perioperative period, so longer-term DVT outcomes require future research. Ultrasound is the most commonly used method for lower-extremity DVT diagnosis, but misdiagnosis remains possible. Deep vein thrombosis is a blood clot in the deep veins of the leg that carries a risk of pulmonary embolism if the clot migrates. Left-leg swelling can be associated with cardiac insufficiency, the heart's inability to pump blood efficiently, leading to fluid backup. When DVT is diagnosed after admission, preoperative waiting time may be extended by more than 48 hours due to anticoagulation treatment and specialist consultations, potentially delaying timel…
