Locationsinclude: pelvis, calf, thigh. Less commonare arm, chest, and other locations.DVT is common complication inhospitalizations, surgery, andimmobilization.Orthopedic Procedures:examples include total hipreplacement, hip fracture, totalknee replacement.Atrial Fibrillation:A-fib cancause thrombi within atria thatcan enter general circulationand cause stroke.
