We report herein the unusual case of a patient in whom postoperative angiography following coronary artery bypass grafting (CABG) revealed a lateral origin of the right internal thoracic artery (ITA) and a normal origin of the left ITA, both of which were demonstrated to be patent and did not follow a tortuous course. The CABG had involved revascularization(More)
OBJECTIVE A prospective randomized trial was performed to investigate the prognostic advantage of postoperative adjuvant chemotherapy in patients with resected stage I-II non-small cell lung cancer (NSCLC). PATIENTS AND METHODS From March 1992 to December 1994, 221 patients with completely resected stage I-II primary NSCLC were enrolled and randomly(More)
Cardiopulmonary bypass with 17 to 57 per cent dilution of hemoglobin for repair of ventricular septal defect (VSD) was applied to 26 infants weighing less than 10 kg at normal temperature. The higher flow rate was required to compensate the reduced oxygen carrying capacity and to maintain an adequate arterial pressure in proportion to a decrease of(More)
We herein report the case of a 56-year-old man with idiopathic thrombocytopenic purpura who required an emergency aortic arch replacement. Intraoperatively, hemostasis was achieved using platelet transfusions. Postoperatively, the use of high-dose γ-globulin therapy was able to maintain an adequate platelet count and good hemostasis.
The effects of calcium antagonists (nifedipine, nicardipine, diltiazem, and verapamil) and prostaglandin E1 (PGE1) on the tension of isolated canine coronary arterial strips were studies. In a solution containing 20 mEq/L of K+, 127 mEq/L of Na+, the tension was increased by 500–1,000 mg with 4 mEq/L of Ca2+. This increase in tension was suppressed by(More)
We present a case of pulmonary varices in a 44-year-old man. The patient's chest X-ray films revealed well-delineated shadows in the right lower lung field. An enhanced chest CT scan with three-dimensional volumetric imaging demonstrated a vascular malformation in the right lower lobe. Both the arterial and parenchymal phases of digital subtraction of the(More)
Effects of prostaglandin E1 (PGE1) and phenoxybenzamine (POB) on the hemodynamics during cardiopulmonary bypass (CPB) were studied in 30 infants and children. Patients were grouped into three; PGE1 was given to ten patients, POB to another ten, and the other ten patients served as the control. Vasodilative drugs were witheld. PGE1 was infused at 0.01 to(More)
The effects of magnesium on the tension of isolated canine coronary arterial strips were studied. In the solution containing K+ of 20 mEq·l −1, Ca2+ of 4 mEq·l −1, and Na+ of 127 mEq·l −1, the tension was 811±111 mg with Mg2+ of 1 mEq·l −1, 494±135 mg with Mg2+ of 10 mEq·l −1, 272±126 mg with Mg2+ of 20 mEq·l −1, −52±63 mg with Mg2+ of 30 mEq·l −1, −69 ±80(More)
A safe limit of hemodilution in cardiopulmonary bypass (CPB) for open heart surgery was investigated by analyzing of the perfusion results of 100 patients with tetralogy of Fallot (TOF) and ventricular septal defect (VSD). The higher perfusion flow was necessary to compensate for the reduced oxygen carrying capacity and to maintain adequate arterial(More)
