Ascending to Abdominal Aorta Extraanatomic Bypass for Descending Aortic Coarctation: A Reconstruction Technique without Laparotomy or Left Thoracotomy.

The descending aortic coarctation is often difficult to anatomically reconstruct. We report two cases of ascending aorta to abdominal aorta bypass without laparotomy or thoracotomy. This approach enabled us to avoid anastomosis close to the inflammatory lesion and left thoracotomy causing bleeding from the collateral vessels, and to allow concomitant cardiac procedures to be performed.

Comparison of medically versus surgically treated acute type a aortic dissection in patients <80 years old versus patients ≥80 years old.

Although recent progress in emergency surgery has resulted in an increase in the indication for older patients with acute type A aortic dissection (AAD), some patients remain who cannot undergo surgical treatment and little is known about the prognosis of patients with AAD who receive medical treatment, especially in elderly patients. Of the 82 patients with AAD who were admitted to our institution, 48 received medical therapy only. We retrospectively reviewed their clinical data and analyzed the prognostic value of the clinical characteristics in both younger and older patients.

[Traumatic aortic regurgitation complicating chronic bronchitis; report of a case].

A 61-year-old man with diabetes mellitus and chronic bronchitis was brought to the hospital after falling from a roof accidentally. He received blunt trauma to the left chest wall including left rib fractures, pneumothorax, hemothorax and a fracture of left scapula. After endotracheal intubation and chest drainage, he was transferred to the intensive care unit.

[Sequential bypass grafting with arterial grafts can be functioned? Assessment of evaluation for function of sequential bypass grafting from theoretical model].

As total arterial revascularization in coronary artery bypass grafting (CABG) has been recommended, a sequential bypass technique using arterial grafts has been induced. We evaluate whether a sequential bypass graft can be functioned or not by using a simple simulation model for coronary circulation analogous to the electrical circuit based on Ohm law. The ratio of flow between graft and native coronary artery was determined by the severity of stenosis in the bypassed vessels and the graft diameter.

Bypass balloon pumping: a newly developed device for mechanical circulatory support in heart failure.

Various types of assist devices have been developed for severe heart failures. Among them, intra-aortic balloon pumping (IABP) has achieved popularity, mainly in the treatment of patients with either severe cardiac infarction or low cardiac output syndrome (LOS) after open-heart surgery. However, IABP has a limitation in that although it acts as a pressure support, it cannot directly support flow volume.
