Pulmonary embolism and deep vein thrombosis are different aspects of a single problem, thromboembolic disease, which is frequently asymptomatic. The incidence and clinical significance of thromboembolic disease is uncertain. The mortality of untreated pulmonary embolism is unknown but may be much lower than is generally thought. Investigation of the lower limbs is desirable in most cases, even when there are no symptoms in the legs, in order to evaluate the prognosis and the need for anticoagulant therapy. Not all cases of pulmonary embolism require treatment. The presence or absence of risk factors may be important in determining the appropriate length of treatment.
肺栓塞和深静脉血栓形成是同一问题（血栓栓塞性疾病）的不同方面，该疾病通常无症状。血栓栓塞性疾病的发病率和临床意义尚不确定。未经治疗的肺栓塞死亡率未知，但可能远低于普遍认为的水平。在大多数情况下，即使腿部没有症状，也需要对下肢进行检查，以便评估预后和抗凝治疗的必要性。并非所有肺栓塞病例都需要治疗。危险因素的存在与否在确定适当的治疗时长方面可能很重要。
