Prognosis
DVT should be managed on time otherwise it will lead to serious medical conditions. It is necessary to carry out special precautions on time. Several options are available based on the severity and illness of the patient. In the case of untreated lower extremity DVT, the risk of fatal pulmonary embolism would be 3%, while the risk due to upper extremity DVT is very rare. The risk of recurrent DVT is low for patients with transient risk factors such as surgery, trauma and temporary immobility. While the risk is high in patients with persistent risk factors such as cancer, idiopathic DVT, or the incomplete resolution of past DVT. It is difficult to predict the risk of venous insufficiency. Also, the other risk factor for certain syndromes may aggravate and induce DVT, like body mass index ≥ 22 kg/m2, recurrent ipsilateral and proximal thrombosis are the risk factors for the post-phlebitic syndrome.
