Optimal blood flow for cooled brain at 20 degrees C.

Background: Optimal conditions for deep hypothermic perfusion and protective brain blood flow remain unclear.

Methods: Dogs (n = 52) underwent 120 minutes of cardiopulmonary bypass at 20 degrees C with perfusion flow rates of 2.5, 5, 10, 20, 40, and 100 mL x kg(-1) x min(-1).

[Results of muscle flap repair for deep mediastinitis and graft patency after coronary artery bypass grafting].

Between 1978 and 1997, 9 patients developed poststernotomy mediastinitis after coronary artery bypass grafting. Four of these patients (group A) were treated with open drainage and mediastinal irrigation or omental transfer. The other 5 patients (group B) were treated with primary wound closure by the technique of muscle flap mobilization.

Ruptured aneurysm of the ductus diverticulum into the pulmonary artery in a man: a successful repair.

Aneurysm of the ductus diverticulum in the adult is rare and its rupture is fatal. A 75-year-old man presented with congestive heart failure that suddenly occurred with a continuous murmur. Angiography showed a left-to-right shunt through a large thrombosed aneurysm of the ductus diverticulum (6 cm), and the pulmonary-to-systemic flow ratio was 2.

[Use of ultrasonically activated scalpel for the paced patient--a case report].

A paced patient underwent mitral valve replacement for mitral stenosis using ultrasonically activated scalpel. There were minimum bleeding and no homologous blood transfusion was required. Ultrasonically activated scalpel fid not interfere the pulse generator nor the transesophageal echocardiography.

Regional tissue blood flow and pH in the brain during deep hypothermic retrograde brain perfusion.

Deep hypothermic retrograde brain perfusion is used to protect the brain during aortic arch operations. However, all experiments have failed to demonstrate retrograde blood flow in the brain tissue. We developed an experimental model of sagittal sinus and simultaneous superior vena cava perfusion.

[Oozing type left ventricular rupture: report of three cases].

Two cases of postinfarction oozing type left ventricular rupture and a case of oozing type left ventricular rupture due to catheter perforation for left ventriculography are reported. The technique used to repair the rupture is fibrin glue-oxycellulose fixation method. The post operative course of three cases were uneventful.

[A left subclavian arterial aneurysm caused by fibromuscular dysplasia: a case report].

A 70-year-old man complained left supraclavicular pulsatile tumor. Angiography and CT revealed the left subclavian arterial aneurysm that was just behind the clavicle. The aneurysm was resected through a cross-clavicle incision and an 8 mm Hemashield graft was implanted.
