Background: Pulmonary embolism is often undetectable because the symptoms are not specific and cannot be prevented. The PE mortality rate ranges from 100,000 to 200,000 deaths in the United States. Even this figure can increase if it is not handled immediately. History, physical examination and examination of supporting devices such as ECG, thoracic photo, D dimer, fibrinogen, echocardiography and sophisticated procedures such as CT angiography.
Case: There were 4 cases reported. The first, second and third cases occurred pulmonary embolism after postoperative. We used Wells and Geneva scoring to support the diagnosis of pulmonary embolism. Whereas the fourth case is different, using D-dimer, desaturation and elevation of the right heart are signs of pulmonary embolism. Appropriate treatment using heparin or streptokinase even DSA is a modality if massive embolism occurs.
