Diagnosis
Invite 20% - 30% The patient has not or failed to be diagnosed and treated and died in time, if can diagnose and for the anticoagulatory treatment in time, the case fatality rate can be expected to drop to 8%, so early diagnosis is very important. Should collect the medical history carefully. Serum LDH is raised, the arterial blood PO2 drops, PA-aO2 increases widely. Electrocardiogram have the intersection of T and wave and section ST change ' Similar myocardial infarction figure) , the intersection of P and wave and QRS wave form change ' Similar acute lung worry figure) . The X-ray does not reveal spot slice soaking, lung one, diaphragm skin raising, thorax accumulate the liquid, especially regard pleura as the basal convex to move towards the round dense shade (Hamptom hump) in the lung door And the lung artery expanded accompanies and carries the lung line far sparsely (Westermark solicit) ,etc. capital for diagnosis of pulmonary embolism values important. Nuclide lung keep in touch with pour into, scan, diagnose the intersection of pulmonary embolism and there is not creating methodding most sensitive, although the specificity is low, there are typical occuring frequently, segment or Tenneco to pour into defect and keep in touch with normally or increase, it is clinical to combine, diagnose that can establish. Diagnose the most peculiar method of pulmonary embolism in artery radiography of lung, are suitable for the clinic and nuclide to scan suspiciously and needing the case of surgery treatment. It if you can't show as by blood vessel, last defect, block at artery or " The evidence of prunning branches " . Radiography can't reveal, less than or equal to the intersection of 2mm and the intersection of diameter and small blood vessel, so person who occur frequently light thromboembolism often easy to leak, examine. Magnetic resonance, for having technologying of creating etc. useful that pulmonary embolism diagnose, can see the obvious lung artery and fill defect when the relatively loud thromboembolism.
Pulmonary embolism is apt and pneumonia, pleurisy, pneumothorax, hindering many kinds of disease lookses such as lung, lung tumour, coronary heart disease, acute myocardial infarction, congestive cholecystitis, pancreatitis in heart failure slowly, need to distinguish carefully.
