title: Clinical evaluation of computed tomography-guided versus ventriculography-guided thalamotomy for movement disorders.
abstract: 38 patients with Parkinsonian or essential tremor who underwent thalamotomy based on ventriculographic coordinates were compared to 23 patients whose thalamotomy was performed on the basis of computed tomography (CT)-derived target coordinates. The comparison between the two groups concerned the age, sex, duration of disease, target side, intra-operative target correction, duration of postoperative stay in hospital, transient side-effects, permanent complication, and tremor alleviation. The study showed that the surgical results in terms of tremor control were the same in the two groups. However, the percentage of post-operative transient side-effects was higher and the duration of stay in hospital was longer for the ventriculographic patients than for the CT patients.
