Abstract

One of the best procedures to prevent haemarthrosis has been radioactive synovectomy (synoviorthesis). Since the first report of radioactive synovectomy in haemophilia of Ahlberg in 1971 [1], many centres adopted this procedure as the one of choice, through fibrosing the synovial membrane, prevent further haemarthrosis. Since 1976 we have performed 104 such radioactive synoviorthesis in 97 patients, age ranging from 6 to 40 years with a mean of 10 years. Sixty-five of these patients were under 12 years of age. The knees were injected in 61 cases, elbow in 26 cases, ankles in 14 cases and shoulders in three cases. The clinical results of this procedure show 80% of excellent results with no further bleeding. In case of failure, a new injection can be given in thesame joint at a 6-month interval, or an injection for the same purpose in other joint. One of the criticisms against this method is the possible chromosomal damage induced by the radioactive material. In our centre, four studies have been carried out in order to see whether these changes, when they occur, are everlasting; all have demonstrated thatchromosomal changes are reversible. The radioactive material used in the two first studies was Gold-189 (Au-189). In 1978, 354 metaphases were studied with 61 ruptures, 17.23% (nonpremalign) and six structural changes, considered premalign (1.69%). Any number below 2% is considered not to be dangerous. A further study was done in 1982, in the same group of patients with aresult of 21 ruptures (3.34%) and no structural changes, This demonstratedthat the possible premalign changes disappeared with time. A third study was performed in a series of 13 patients that sustained radioactive synoviorthesis with Rhenium-186 (Re-186) in November 1991. For comparison, we carried out a chromosomal study just before and 6 months after the radioactive material injection. The results confirmed that changes that could be linked to the radiation, appeared equally in nonirradiated patients, and those changes due to the radiation disappear with time, never reaching the dangerouszone of 2%. In the group treated with Re-186 we studied an additional number of 130 metaphases with identical results and no structural changes. In astudy on patients where Y-90 was the radiocolloid, no premalign change wasfound before or after the synoviorthesis. It seems, in view of these results, that radioactive synovectomy is safe and gives great benefits to the haemophilic patients.
