The anatomic distribution and pulmonary embolism complications of hospital-acquired lower extremity deep venous thrombosis

HA-LEDVT is characterized by a significantly high percentage of DVT in muscular calf vein. Muscular calf vein thrombosis may be the primary origin of lower extremity deep vein thrombosis. Diameter of thrombus in muscular calf vein may be associated with the occurrence of PE. More prospective studies are needed to more fully determine the natural history of HA-LEDVT and develop prevention and treatment guidelines for HA-LEDVT.
