ABSTRACT
Objectives: The aim of this study was to investigate the relationship between preoperative 10m gait speed and ADL disability in patients undergoing cardiovascular surgery. Methods: There were 131 patients who underwent scheduled cardiovascular surgery and pre and postoperative ADL evaluation from June 2014 to December 2017 in our hospital. A total of 19 patients, including 13 whose Barthel Index (BI) was lower than before surgery at discharge and 6 who had a long-term hospital stay of 6 weeks or more after surgery, was defined as the ADL disability group. The other 119 patients were defined as the control group. We retrospectively compared the two groups and searched for predictors of postoperative ADL disability. Results and Conclusions: An independent predictor of postoperative ADL disability was identified: more than 7.04seconds for walking 10m.
ABSTRACT
An 80-year-old woman presented with dilatation of the distal aortic arch due to chronic type B aortic dissection. She underwent thoracic endovascular aortic repair (TEVAR) in zone 2 with GORE TAG thoracic endoprostheses (40 mm-15 cm and 34 mm-20 cm) for closure of the entry site at the proximal descending aorta. TEVAR was successfully performed and blood flow in the false lumen stopped. Two months after TEVAR, she was admitted to our hospital owing to syncope. A CT scan revealed type A aortic dissection, and emergency surgery was performed. The entry was proximal to the stent graft, and we performed total arch replacement with preservation of the stent graft. Retrograde type A aortic dissection is a rare but lethal complication of TEVAR. Careful consideration of the device selection is needed, and attention should be paid to the placement of the stent graft.
ABSTRACT
An 82-year-old woman fell into a state of shock during the treatment for a urinary tract infection. Computed tomography and transthoracic echocardiography revealed massive pericardial effusion. Pericardiectomy was performed in the operating room and hemorrhagic effusion was observed. Emergent sternotomy was performed, and the bleeding site was located at the posterior portion of the left ventricular outflow. We diagnosed a rupture of a left ventricular outflow tract pseudoaneurysm after infectious endocarditis. A pericardium patch closure of the pseudoaneurysm and an aortic valve replacement were performed. The patient was discharged 35 days after the operation without recurrence of infection. Left ventricular outflow tract pseudoaneurysms is an uncommon complication following infective endocarditis, aortic valve surgery or chest trauma. Transesophageal echocardiography and multidetector-row computed tomography (MDCT) is useful for identifying such lesions.
ABSTRACT
A 65-year-old man had received closure of the entry and false lumen Stanford type B acute aortic dissection via left thoratectomy 23 years previously. The patient underwent emergency graft replacement for a ruptured aneurysm of the thoraco-abdominal aorta 10 years previously. Enhanced computed tomography (ECT) revealed that the residual aortic dissection of the distal arch and the descending aorta were dilated. Reoperation via left thoracotomy usually requires a long cardiopulmonary bypass time and intraoperative bleeding. So we selected to perform open stent-grafting through median sternotomy alone, avoiding a left thoracotomy.
