The patient was a 61-year-old woman. In April 2005, she suffered a cerebral infarction and became paralyzed on the right side. In June 2005, a stent graft was placed to treat significant stenosis of the right coronary artery. Computed tomography (CT) in October 2006 revealed widespread patent aortic dissection in both the true and false lumens, extending from the origin of the ascending aorta to the three arch branches and both femoral arteries. Preoperative coronary angiography also showed occlusion of the left anterior descending branch. As a result of these findings, widespread Stanford type A chronic aortic dissection with coronary artery disease was diagnosed, and surgery was performed in February 2007. Brachiocephalic artery dissection and severe stenosis of the right subclavian artery were present, and the left common carotid artery and left subclavian artery were also dissected distally. In addition, both the true and false lumens were patent distal to the aortic arch, with the major abdominal branch bifurcating from both lumens and the dissection extending to the femoral artery, requiring cannulation of both lumens. During surgery, extracorporeal circulation was established by means of blood removal from the right atrium, transapical aortic cannulation, and cannulation of both luminens of the left femoral artery, in an effort to prevent malperfusion due to hypothermia. For revascularization, a Y-shaped artificial blood vessel was used to reconstruct the three arch branches first (the arch-first technique), after which an I-shaped artificial blood vessel was used to form anastomoses distally with both lumens, ensuring perfusion to the false lumen. The proximal anastomosis was then formed, and finally, a single coronary artery bypass graft (CABG) branch was performed using a great saphenous vein graft. No postoperative complications were encountered, and CT showed good blood flow through both luminens below the graft and aortic arch. The patient was discharged from hospital and returned home in an anbulatory condition independently 18 days postoperatively. In this case of widespread type A chronic aortic dissection, the cannulation site was selected and the order of reconstruction and methods of anastomosis were carefully chosen to avoid cardiac malperfusion during arch replacement, resulting in a good outcome.

Left ventricular thrombus is a complication of left ventricular dysfunction, including acute myocardial infarction, cardiomyopathy, and severe valvular heart disease. Surgical removal should be considered when a thrombus is mobile, when thromboembolism occurs, and when cardiac function has the potential to improve. Two patients with left ventricular thrombus underwent totally thoracoscopic transatrial thrombectomy. A thrombus developed in the apex of the left ventricle after acute myocardial infarction in one patient (Case 1) and during treatment for congestive heart failure in the other (Case 2). The minimally-invasive transatrial approach requires no sternotomy or left ventriculotomy and is thus particularly beneficial for treating left ventricular dysfunction. Moreover, totally endoscopic surgery confers the advantage of a deep and narrow visual field. Therefore, we consider that this strategy is highly effective for treating left ventricular thrombus.

Between Nov. 1981 and Dec. 1990, seventy-seven patients underwent surgical repair for abdominal aortic aneurysm (56, non-ruptured and 21, ruptured). There were no operative and hospital deaths in the non-ruptured group and 4 deaths (19%) in the ruptured group. To improve operative results by means of decreasing hemorrhagic blood loss and operative time, we have ameliolated some points of the technical procedures as follows. Dissection of the perianeurysmal tissue was limited to only the neck and anterior peritoneal surface of the aneurysm. Taping to keep the aorta and distal iliac artery was not applied and vascular clamps were placed without dissection of the posterior walls of the aorta and distal arteries. Proximal anastomosis of the Y-vascular prostheses were performed by the inclusion technique. The end-to-side method was used in distal anastomosis to the external iliac arteries routing behind the ureter. Even when aneurysmal dilatation involved the common iliac arteries, the orifices of the common iliac arteries were closed by continuous sutures bilaterally. In ruptured cases too, this standard technique was used without application of special means for proximal cross-clamping. Postoperative arteriography or enhanced computed tomography reveald thrombosis and reduction in size of residual aneurysm of the common iliac artery. By these improved surgical techniques, 25 cases (45%) of the 56 non-ruptured group had surgical correction of the abdominal aortic aneurysm without using homologous blood transfusion. Cumulative 5-year survival rate by Kaplan-Meier method of non-ruptured and ruptured group was 87% and 49% respectively.

A 37-year-old female was admitted to our hospital because of haemoptysis. She had undergone descending thoracic aorta-abdominal aorta bypass grafting 11 years previously. Then the diagnosis was atypical coarctation due to aortitis syndrome. No follow up had been continued. Angiogram and CTscan disclosed a false aneurysm at the anastomotic site of the descending thoracic aorta, which was ruptured into the left lung. An emergency operation was performed. A new extra-anatomical ascending aorta abdominal aorta bypass was constructed using 16mm Dacron prosthesis, and three permanent clamps were employed for thromboexclusion of the descending aorta, previous bypass graft and the ruptured aneurysm. At present, three years after the operation, she is leading normal life with medication of hypotensive drugs. Pathogenesis, surgical approach and long-term postoperative care were discussed.
