Ten patients, aged 3 to 43 years, with the tetralogy of Fallot underwent <i>in situ</i> pulmonary valve replacement (PVR) 13 times. The implanted valves were a St. Jude Medical prosthesis (3 times) and a bioprosthetic valve (10 times). In 5 patients PVR was performed at the time of radical repair and in the remaining 5 patients PVR was performed after radical repair. Three patients underwent re-PVR at 6 to 13 years after the first PVR. There was one operative death in re-PVR 14 years after the first PVR and one patient died from congestive heart failure 4 years after PVR. In the patients with the tetralogy of Fallot, the rate of PVR in those who had undergone open Brock's operation were significantly higher than that of the patients without open Brock's operation (p<0.05). Actuarial survival rates at 5 years and 10 years were 88.9% and 88.9%, respectively. Rates of freedom from reoperation at 5 years and 10 years were 88.9% and 59.3%, respectively. Although the early operative results are satisfactory, re-PVR is mandatory in the future. Thus the indications of PVR should be considered carefully.

The infected arterial aneurysm has a fulminent infectious process frequently resulting in death if not properly treated. We reviewed 10 patients to identify the aneurysm location, etiology, bacteriology, and the mortality of surgical treatment. The abdominal and thoracic aorta was the most common site (6 cases). The primary causes were infected endocarditis, acute cholecystitis, abscess in the psoas muscle and depressed immunocompetence, but there was no case of iatrogenic trauma. Eight patients had positive blood or aneurysmal wall culture, <i>Staphylococcus aureus, Staphylococcus epidermidis</i> and salmonella being the most frequent bacteria identified. The proper treatment of infected arterial aneurysm remains controversial. Three methods of surgical treatment were performed; one, <i>en bloc</i> aneurysmal excision with <i>in situ</i> prosthetic graft replacement, two, open aneurysmal resection and irrigation with large amount of diluted popdon iodine solution followed by <i>in situ</i> prosthetic graft replacement with wrapping by an omental pedicle. Three, extraanatomical bypass grafting. Six of 7 patients in whom the infection subsided with antibiotic therapy showed good long term results. However, 3 patients with uncontrollable infection died 1 to 3 months after operation.
