Surgical treatment of anomalous origin of the left coronary artery from the pulmonary artery associated with tetralogy of Fallot.

An 8-year-old boy with anomalous origin of the left coronary artery from the pulmonary artery associated with tetralogy of Fallot, which was definitely diagnosed preoperatively, was operated on with success. Direct implantation of the left coronary artery into the aorta following division of the left coronary artery from the pulmonary artery and, concomitantly, total repair for tetralogy of Fallot using an external valved conduit were performed. Postoperative cineangiogram revealed a hemodynamically well-repaired intracardiac condition and anterograde filling of the left coronary artery, compared with retrograde left coronary flow from intercoronary collateral vessels preoperatively. To the best of our knowledge, there is not a previously published report of anomalous origin of the left coronary artery from the pulmonary artery associated with tetralogy of Fallot that was treated surgically with success.

Persistent left superior vena cava draining into the left atrium associated with the atrial septal defect and partial anomalous pulmonary venous drainage: surgical correction with sepcially designed prosthetic material.

Anomalous drainage of the persistent left superior vena cava into the left atrium with partial anomalous pulmonary venous return and the atrial septal defect is relatively rare condition, and there reported various kinds of surgical procedures in correction for this lesion. This report describes the original and simple surgical procedure in total correction of these lesions performed in our institute, using a large Dacron patch connected with a knitted Dacron vascular graft in its center. Surgical correction was accomplished by anastomosis of a Dacron draft with the orfice of the persistent left superior vena cava into the left atrium, widening of the atrial septal defect, and reconstruction of a new atrial septum with a Dacron patch. Postoperative cardiac evaluation revealed good condition of blood stream through a Dacron draft from the left superior vena cava to the right atrium, with corrected pulmonary venous drainage into the left atrium without pulmonary venous congestion and superior vena cava syndrome.

Antiglobulins in juvenile rheumatoid arthritis.

With initial hopes of establishing a diagnostic test for juvenile rheumatoid arthritis (JRA), five types of immunoadsorbents were used to search for occult antiglobulins in sera from children. The immunoadsorbents included glutaraldehyde-aggregated globulin, heat- and glutaraldehyde-aggregated globulin, Affi-Gel-bound globulin, Sepharose-bound globulin, and bromozcetyl cellulose-bound globulin. The glutaraldehyde-aggregated immunoadsorbents retained nonspecific protein. The Affi-Gel, Sepharose, and bromoacetyl cellulose absorbents were effective and specific, but the Affi-Gel and bromoacetyl cellulose were impractical for routine use. Separose-bound globulin was selected for use in a survey of 52 patients with JRA and 8 normal children. Materials resembling occult antiglobulins, measured as acid elutable protein, were found in normal children as well as in children with JRA. Only a small proportion of children with JRA had statistically elevated levels of such occult anti-globulin consisted of IgM, IgG, and IgA, and had latex fixation activity in 2 of 5 tested sera from normal children and in 27 of 52 sera from children with JRA. Thus the presence of antiglobulins per se is not diagnostically helpful in distinguishing children with JRA.
