Late results of the surgical treatment of XXXX .

@entity1 @entity1644
97 @entity1 with @entity1644 were treated surgically during the last 12 years. Only those @entity1 in which the disease showed rapid progression in the last 1/2-1 year were operated. Of these 97 @entity1 54 were followed for 5 years or longer. 28 @entity1 were treated by suboccipital decompression, 17 by terminal ventriculostomy, 4 by myelotomy and syringo-subarachnoid shunt; 5 had a combination of two procedures. Very good results were obtained in 12 @entity1 (22%), satisfactory-in 31 (58%) and poor results-in 11 (20%). Very good results were more often achieved after suboccipital decompression, but each method had as well excellent as unsatisfactory results, and the number of the @entity1 is too small as to allow statistically significant conclusions. It is almost impossible to predict the result of the surgical treatment in @entity1644 , but good results were obtained most often in young @entity1 with relatively short duration of the disease. However, it is not the rule. Satisfactory results can even be obtained in older @entity1 with long lasting disease and poor neurological status. The best method of surgical treatment is still under discussion.
