Overview. Pregnant women have a much higher risk of all types of venous thrombotic emboli (VTE) than the non-pregnant of similar age and there is an even higher risk after caesarean section compared to vaginal delivery. If the vein swells and cause pain and swelling in the leg, the condition is called thrombophlebitis. "If the D-Dimer comes back positive, an ultrasound is done of the extremity, and if a pulmonary embolism is suspected, a CT scan of the chest is done," says Nicholas. Baseline blood tests needed include a platelet count and clotting levels to guide treatment of DVT. The relative risk of travel-related DVT is further increased if other risk factors for developing DVT are present. The colour Doppler demonstrates a loss of colour. Multiple coagulation factors, together with platelets, function together to form a clot, preventing further bleeding. Taking certain blood thinners can help reduce the risk of recurrence.
