Spontaneous remission of chyluria.

The natural history of chyluria is not well known. We have followed 72 patients with chyluria who have not had treatment and the condition has disappeared in 36 cases (50 per cent). In these cases the duration of chyluria varied from 3 days to 20 years, with an average of 44.3 months, but it was less than 6 months in about half of the cases.

Angiocardiography after total correction of tetralogy of Fallot using large homograft arteries.

Postoperative angiocardiographic findings were examined in eight patients whose pulmonary artery was reconstructed using an aortic or pulmonary homograft with valve. Apparent dilatation of the outflow tract of the right ventricle was seen in three patients. Only four showed valve mobility, with function judged almost normal in two of them. Calcification in a valve was not seen. The pulmonary trunk showed three directional patters, and stenosis was clearly observed in two cases. calcification of the pulmonary trunk was seen in only one case. The most difficult problem in the reconstruction of the pulmonary artery is the high incidence of pulmonary stenosis.

Transfemoral plug closure of patent ductus arteriosus. Experiences in 61 consecutive cases treated without thoracotomy.

We successfully closed the isolated patent ductus arteriosus in 58 of 61 consecutive patients using the transfemoral-catheter method originally introduced by Porstmann in 1968. To perform this technique more safely and reliably, some instrumental and technical improvements were made. The indications for this method have been expanded to include the cylindrical or window-type ductus as well as the conical-shaped ductus. Classification into three groups of the configuration of the ductus by angiography has been useful in selecting the shape of the closing plug. Whenever feasible, we consider the catheter technique to be the method of choice to close the ductus.
