Clinical significance
The deep femoral vein is commonly affected by phlebitis which can be a dangerous condition in the case of a thrombus, or blood clot, forming, as the thrombus may dislodge and travel to the lungs, causing pulmonary embolism. Risk factors for deep vein thrombosis include prolonged bed rest following surgery, immobility due to disability or fracture, an excessively sedentary lifestyle or hereditary dispositions such as the factor V Leiden mutation.
