title: Normal arterial blood gas in a patient with saddle pulmonary artery embolus: diagnosis by transesophageal echocardiography.
abstract: This article describes a patient with a large, main pulmonary artery thromboembolus with normal arterial blood gas results, including normal alveolar-arterial oxygen gradient. The diagnosis was established using transesophageal echocardiography and confirmed with pulmonary angiography. The patient subsequently underwent anticoagulation and eventually was discharged without complications.
