Particularly pseudoaneurysm due to postoperative infection in the ascending aorta requires surgical treatment with antibiotics. If a large sized pseudoaneurysm is located at the retrosternal space then there is a very high risk of massive bleeding from rupture during performance of resternotomy. To avoid this risk we performed femoro-femoral bypass under moderate hypothermia with transient circulatory arrest and we report here on the successful result of this case. Keywords aortic pseudoaneurysm aortic valve replacement moderate hypothermia Background Thoracic aortic pseudoaneurysm is a very rare complication after cardiac surgery with an incidence of less than 0.5 1 . It has been reported that leaking at an aortic cannulation site is the major risk factor of pseudoaneurysm 2 and deep sternal infection or an increased possibility of suture dehiscence such as after an ascending aortic dissection showed the high occurrence of pseudoaneurysm 3 . A simple chest PA can detect widening of the mediastinum if the pseudoaneurysm is large and the diagnosis can be confirmed with chest CT and an echocardiogram. Case presentation A 69 years old female patient was hospitalized for dyspnea which was her chief complaint. The echocardiogram during the visit showed severe mitral stenosis MVA 0.8 cm2 and aortic stenosis AVA 0.7 cm2 . Mild pulmonary hypertension RVSP 34 mmHg and grade I tricuspid regurgitation were also present with a left ventricular ejection fraction of 43 . Left ventricular hypertrophy was present and the left ventricular wall motion was generalized hypokinetic but no localized wall motion .
