Case Reports
[A case of huge abscess extended from anterior neck to left lung and lateral chest wall].
62-year-old woman admitted our hospital with pain of left upper extremity from the left chest and dysphasia. Chest X-ray showed the huge mass shadow in the left lung field. Diabetes mellitus and inflammatory reaction such as high fervor, leukocytosis, CRP and ESR accentuation were recognized. ⋯ Inflammation and mass shadow of left upper lung field have decreased gradually. The patient discharged without bronchoalveolar fistula. Abscess extending from the neck or chest wall with diabetes mellitus is very rare.

Comparative Study
[The comparison of tepid and moderate hypothermic cardiopulmonary bypass in cardiac surgery].
Normothermic cardiopulmonary bypass (CPB) is being increasingly used at some institutions. Patients undergoing normothermic CPB have a higher systemic oxygen demand and may be at higher risk for ischemic injury. This study was designed to confirm the clinical efficacy and safety of tepid hypothermic CPB. ⋯ This study suggests that tepid hypothermic CPB is a safe and effective alternative to moderate hypothermic CPB for patients undergoing open heart surgery. Previous reports have documented that patients undergoing normothermic CPB are at greater risk for cerebral desaturation. We should evaluate cerebral venous oxygen saturation during tepid hypothermic CPB before the induction of normothermic CPB.

Hemodynamic effects of amrinone in children during cardiopulmonary bypass (CPB) and postoperative 12 hours were studied. In 10 patients undergoing open heart surgery, 1 mg/kg of amrinone was infused as the initial CPB dose and 5 - 10 micrograms/kg/min of amrinone was continuously administered as the maintenance dose during CPB and postoperative 12 hours. Amrinone levels ranged from 0.9 to 1.4 micrograms/ml during CPB and postoperative 12 hours. ⋯ The postoperative course of 10 patients was clinically uneventful. The administration of amrinone in 10 patients did not produce thrombocytopenia compared with the control group (5 patients) in the postoperative period. In conclusion, the administration of amrinone during CPB and postoperative 12 hours in children was useful in producing enough vasodilating effect without major side effect.

A 68-year-old woman with mitral valve regurgitation due to ruptured chordae tendineae of posterior leaflet underwent mitral valve repair by replacement of chordae tendineae with EPTFE sutures and Carpentier-Edwards ring techniques. Preoperative study showed massive mitral regurgitation and moderate tricuspid regurgitation with CTR 54% of chest X-ray. The postoperative course was not eventful. ⋯ Postoperative CTR was 45%. Mitral valve repair by these techniques could be modified and applicable to mitral valve regurgitation due to ruptured chordae tendineae of posterior leaflet. There was no complication during follow-up period of 8 months.
