A case of successfully treated traumatic aneurysm of the thoracic aorta with severe major air way compression was reported. A 38-year-old man, who had a history of blunt chest trauma in a traffic accident twenty years ago, complained of asthma-like coughing chest CT scan and angiogram showed a saccular aneurysm of desending aorta compressing the isthmus of(More)
Coronary artery bypass graftings (CABG) in elderly patients are increasing in recent years. Several studies have shown that the rate of complications and mortality is higher in elderly patients than in younger ones. This report presents results of CABG in octogenarians. From January 1996 to December 1999, 362 patients underwent isolated CABG, of whom 15(More)
Three patients with 3-channeled dissection were operated upon. Images of the dissection were enlargement of the false lumens, compression of the true lumen by enlarged false lumens and visceral arteries of false lumen origin. These prevent the use of cardiopulmonary bypass (CPB) and cause malperfusion of the viscera. Three-channeled dissecion is easy to(More)
In surgery for Stanford type A aortic dissection (SAAD) with intimal tear in the arch or proximal descending aorta, we performed total arch replacement with frozen elephant trunk technique for the purpose of achieving complete exclusion of the entry. To reduce the circulatory arrest time, we developed a quick stent graft placement method in the proximal(More)
OBJECTIVES Acute massive pulmonary embolism (AMPE) is a life-threatening condition that often induces rapid haemodynamic deterioration. The mortality of surgical embolectomy is still poor in patients with preoperative cardiopulmonary arrest (CPA). We analysed the outcome of surgical pulmonary embolectomy for haemodynamically unstable patients. METHODS(More)
BACKGROUND Although aortic valve replacement (AVR) is the only effective treatment for patients with aortic stenosis (AS), it is recognized that the use of small prosthetic valves due to a small aortic root often affects postoperative course after AVR. The aim of this study was to determine whether the use of small prosthetic valves was a risk factor of AVR(More)
The incidence of infection after pacemaker implant has been reported to occur rarely but it's one of the severe complication. Pacemaker lead sometimes imbedded in the right atrial and ventricular wall, and it seemed to be difficult to remove the pacemaker lead by closed techniques. The optimal treatment is total removal generator and pacing lead, therefore,(More)
213 patients who underwent surgical treatment for the valvular disease through partial sternotomy were studied. We started the minimally invasive valvular surgery in July 1997. All the valvular diseases were indicated for the minimally invasive surgery except for the annulo-aortic ectasia and the concomitant disease with coronary artery bypass surgery.(More)
A 47-year-old man with sever angina pectoris was referred for surgery. Preoperative coronary angiogram revealed giant multiple aneurysms of RCA (Seg 1-Seg 3) and LCX (Seg 11) and LAD (Seg 6). Stenoses were found distal to aneurysm, 90% in RCA-Seg 4, CX-Seg 11, 100% in LAD- Seg 6 and DX-Seg 9 and OM-Seg 12, with collaterals from RCA to LAD. Left ventlicle(More)
