ABSTRACT
A 31-year-old man fell into syncope caused by compression by a machine in his factory. He was taken to the nearest hospital at once for treatment. His chest X-ray seemed normal and his general condition improved. He received no medical treatment and was allowed to return home. Two days later, he went to the hospital for further investigation, and contrast-enhanced chest computed tomography (CT) was performed. Chest CT showed aortic dissection from the ascending aorta to the aortic arch. Therefore, he was admitted for bed rest with antihypertensive therapy. He was discharged on the 35th day after the accident. However, the diameter of the ascending aorta was found to have become dilated, and so he underwent ascending aorta and hemiarch replacement at our hospital. His postoperative course was uneventful, and he was discharged on the 16th postoperative day. We report a rare case of an acute aortic dissection caused by blunt chest trauma.
ABSTRACT
A 61 year-old man was admitted with fever and chest discomfort. He had undergone aortic root replacement for annuloaortic ectasia at age 57. Computed tomography showed a pseudoaneurysm and an abscess formation around the aortic root. Prosthetic valve endocarditis was diagnosed and the underwent repeat aortic root replacement. After debridement and irrigation of the abscess cavity, the left ventricular outflow tract was reconstructed with an equine pericardium, which was rolled to form a conduit. The pericardial conduit was securely sutured to the healthy left ventricular wall and the mitral annulus. A 25 mm-Freestyle valve was then sutured to the distal end of the conduit. The previous prosthetic vascular graft was removed and Completely replaced with a new prosthesis. This method provided secure fixation of a new prosthetic valved conduit to the normal left ventricular tissue with an excellent operative visual field.
ABSTRACT
Aggressive anticoagulation therapy is necessary when Toyobo-LVAS is used for long-term treatment of severe heart failure. However, it is necessary to regulate it carefully if there is a hemorrhagic complication due to thromboembolism, but repeated blood testing is painful. We compared simple measurement with the CoaguChek XS<sup>®</sup> with the conventional blood testing method. The correlation coefficient was 0.916, and the regression line was <i>Y</i>=0.8027<i>X</i>+0.3399. In addition, drawing blood using the CoaguChek XS<sup>®</sup> was very effective in the reported pain reduction in patients.
