[The management of mediastinitis after cardiac surgery].

Of 1067 consecutive patients who underwent cardiac surgery from 1985 to 1992, 19 (1.7%) patients experienced sternal wound complications. All patients required operative intervention with positive bacterial cultures. Before 1990, a group of 13 patients were treated by continuous closed irrigation with dilute povidone-iodine solution. Four patients died (30%). In another group of 6 patients who received omental or pectral muscle flap transfer after 1990, 2 patients died (33%). The mean duration of hospitalization for mediastinitis was 63 days in this group, which was significantly shorter than that of the former group (105 days). From these experiences, we conclude that omental or pectral muscle transfer is an excellent method of management for mediastinitis after cardiac surgery, and is better than continuous closed irrigation method.

[Comparison of long-term clinical results and cost-effectiveness of percutaneous coronary angioplasty and coronary artery bypass grafting].

Cost-effectiveness was studied in 313 cases who had PTCA and 161 cases who had CABG as a first measure of interventional therapy for their coronary heart disease. Follow-up time ranged from 2 years to 5 years and 9 months with a mean interval of 3 years and 10 months. In the PTCA group a mean of 1.33 successfully dilated vessels/patient was obtained, but a total of 100 additional PTCA or bypass surgery procedure was necessary in the follow-up period. In the CABG group a mean of 2.60 patent grafts/patient was obtained. Mean length of hospital stay and charge was 21.9 days and 2,071 thousand yen in the PTCA group, and 82.2 days and 5,122 thousand yen in the CABG group through the entire follow up period. Cardiac event-free survival rate was significantly worse in the PTCA group. In the subgroup of two vessel disease, mean number of successfully dilated targets or patent grafts was 1.32 in the PTCA group and 1.88 in the CABG group. Total length of hospital stay and charge was 24.1 days and 2,352 thousand yen in the PTCA group and 86.2 days and 4,903 thousand yen in the CABG group. Cardiac event-free survival rate was significantly worse in the PTCA group. In the subgroup of three vessel disease, PTCA yielded 1.34 dilated target vessels, whereas CABG 2.66 patent grafts, which was two times more than the former one. Total length of hospital stay and charge was 32.7 days and 2,612 thousand yen in the PTCA group, and 82.4 days and 5,225 thousand yen in the CABG group.(ABSTRACT TRUNCATED AT 250 WORDS)

Aneurysmal change of the ductus arteriosus after prostaglandin E1 administration for pulmonary atresia: demonstration with magnetic resonance imaging.

We report a case of pulmonary atresia in which the ductus arteriosus underwent aneurysmal dilatation after infusion of prostaglandin E1 incorporated in lipid microspheres. To our knowledge this is the first case in which this rare morphological change has been demonstrated with the noninvasive method of magnetic resonance imaging.
