Abstract

It has been shown in Chapters IV and V that several patient-AVM constellations (risk profiles) which give good and poor results are similar in the operated and the nonoperated group. It has previously been reported 52 that operable patients have a favourable prognosis even without operation and this finding has been used as an argument in support of conservative treatment. Our study has shown that this conclusion is not correct as we found a higher frequency of good results for congruent risk profiles in the operated group. We therefore conclude that surgical treatment of AVM is probably to be preferred to conservative treatment. This conclusion is drawn with certain reservations, however, as for parts of the riskprofile scale there are only a few patients with congruent risk profiles, where a comparison is possible. Only in one of the three subgroups of measurement there is a significant difference in treatment results in favour of the operated group (p < 0.01), while in the other two there is no difference (see Fig. 28, Chapter V).
