The length of the aorta from the subclavian artery to the renal artery based on computed tomographic measurements in Japanese adults.

To estimate the length of the aorta from the subclavian artery to the renal artery in Japanese adults, its length was measured on computed tomographic (CT) images. Data from a total of 110 patients without aortic or aortic valvular diseases (54 men, 56 women) who had undergone 7-mm-slice-interval CT examination of the entire aorta was analyzed in this study. The length of the aorta was found to be 214.

Scintigraphic assessment of the effects of bone marrow-derived mononuclear cell transplantation combined with off-pump coronary artery bypass surgery in patients with ischemic heart disease.

Unlabelled: Myocardial SPECT may be useful for assessment of the therapeutic effects and the mechanisms of cardiac regeneration medicine. We aimed to assess first the feasibility and the short-term safety of autologous bone marrow-derived mononuclear cell transplantation (BMCT) into the ischemic myocardium in patients who undergo off-pump coronary artery bypass surgery (OPCAB). In addition, we aimed to assess our hypothesis that the BMCT may help ameliorate myocardial perfusion in patients with ischemic heart disease (IHD) using myocardial perfusion scintigraphy.

Changes in platelet aggregation during cardiopulmonary bypass: comparison of poly-2-methoxyethylacrylate and heparin as a circuit coating material.

At present, there are various biomaterials that have high biocompatibility. In particular, there are many types of coated circuits in cardiopulmonary bypass (CPB) systems. However, only a few clinical studies have investigated platelet aggregation caused by these coated circuits.

Repair of the aortico-left ventricular tunnel originating from the right aortic sinus with severe aortic valve regurgitation.

A 31-year-old adult with an aortico-left ventricular tunnel (ALVT) arising from the right aortic sinus is reported. Preoperative transesophageal echocardiography demonstrated a ruptured sinus of Valsalva with severe aortic valve regurgitation which originated from the right coronary sinus entering the outlet portion of the left ventricular outflow tract. Operation revealed the aortic entrance of the tunnel was above the right coronary sinus.

CT features of chronic contained rupture of an abdominal aortic aneurysm.

Four cases among the 149 patients who required repair of an infrarenal abdominal aortic aneurysm (AAA) during the last five years, were chronic contained rupture. The first symptom at onset was back pain and physical examination revealed the patients to be in no acute distress. The sites of rupture were posterior in all cases.
