Value of transoesophageal echocardiography for diagnosis of intraoperative tumour embolization

Abstract

Malignant neoplasms such as renal cell carcinoma may invade the inferior vena cava leading to a risk of pulmonary tumour embolization during surgical excision. Although massive pulmonary tumour embolism occurs relatively rarely, it can have catastrophic consequences. We report the case of an acute intraoperative pulmonary tumour embolism during resection of a renal cell carcinoma. The use of transoesophageal echocardiography allowed the immediate diagnosis and appropriate management of the underlying cause of acute haemodynamic instability. The role of transoesophageal echocardiography in the diagnosis of pulmonary embolism is discussed.
