Abstract
Summary Twenty joints in 19 haemophiliacs were treated by radioactive synoviorthesis with gold (Au 198) to prevent recurrent haemarthrosis. Twelve knees, six elbows and two ankles were treated in two separate groups (29. 9. 76 and 9. 5. 77). In eight cases (40%) no further haemarthrosis occurred. A diminution of bleeding was obtained in nine cases (45%), a total of 85% good results with 15% failures. One failure in the first group (an elbow) had a second synoviorthesis and was included in the second group also. Prior to synoviorthesis the joint was scanned with technetium (Tc99m) to compare the inflammation of the synovium with that of six months later. The technique including the dosage of Tc99m, Au 198, and factor VIII cover is presented. A leucocyte culture was performed in 16 cases to study any chromosomal breakage, by banding and fluorescent techniques.
