Pitfalls in diagnostic stereotactic brain surgery.

Some of the problems and dangers inherent to stereotaxis are discussed in a series of 243 procedures. Neurological deterioration, either due to haemorrhage or to traumatic oedema, was rare.

This procedure can be considered to lie within the scope of any neurosurgeon.
