Transesophageal echocardiography diagnosis of tricuspid obstruction by a vena cava tumour.

摘要

PURPOSE: To present the anesthetic management for excision of a primary tumour of the inferior vena cava. CLINICAL FEATURES: Resection of a primary tumour of the inferior vena cava without extension to the right atrium was scheduled without extra-corporeal circulation (ECC). The operation consisted of tumour excision with transtumoral clamping. During the immediate postoperative period, tricuspid obstruction was suspected when a "cannon a wave" was recorded from the right atrial pressure curve. Transesophageal echocardiography confirmed the diagnosis of tumour obstruction of the tricuspid valve. CONCLUSION: Tricuspid obstruction due to postoperative mobilization of a primary tumour of the inferior vena cava was diagnosed by transesophageal echocardiography. Perioperative management particularities of the primary tumour of the vena cava are discussed.
