Pseudoaneurysm of surgically reconstructed right ventricular outflow tract complicated by superior vena cava syndrome.

Lee Y, Lee JT, Cho JY, Kim GJ - Korean J Thorac Cardiovasc Surg (2014)

Bottom Line: Pseudoaneurysm of the right ventricular outflow tract (RVOT) has been reported as a rare complication of RVOT reconstruction performed using conduit replacement or patch repair.Rarely, it may present alongside symptoms secondary to the compression of adjoining mediastinal structures.In the present case, superior vena cava syndrome was caused by compression of the superior vena cava, which was a very unusual presentation.

ABSTRACT
Pseudoaneurysm of the right ventricular outflow tract (RVOT) has been reported as a rare complication of RVOT reconstruction performed using conduit replacement or patch repair. Rarely, it may present alongside symptoms secondary to the compression of adjoining mediastinal structures. We report the case of a patient who developed a symptomatic RVOT pseudoaneurysm one month after a total correction of tetralogy of Fallot. In the present case, superior vena cava syndrome was caused by compression of the superior vena cava, which was a very unusual presentation.

f2-kjtcvs-47-541: (A) Chest radiography revealed enlargement of the left upper cardiac border with left pleural effusion. (B) Computed tomography showed a right ventricular outflow tract pseudoaneurysm measuring 55×51×45 mm.

Mentions: One month later, the patient was readmitted to Kyungpook National University Hospital complaining of cough, shortness of breath, and facial and upper extremity oedema over the previous three days. Chest radiography revealed enlargement of the left upper cardiac border with a left pleural effusion (Fig. 2A). In addition, transthoracic echocardiography showed a large aneurysmal dilatation of the RVOT with narrowing of the superior vena cava and main pulmonary artery, secondary to compression by the aneurysm. Colour Doppler images revealed decreased blood flow in the superior vena cava. Computed tomography (CT) showed a narrow communication between the RVOT and an aneurysmal sac. Through these findings, we confirmed an RVOT pseudoaneurysm measuring 55×51×45 mm (Fig. 2B). The superior vena cava was narrow compared to previous CT imaging (Fig. 3).
