2. A CENTER EXPERIENCE

3. IntroductionObjectives
}Stereotactic radiosurgery was
developed with the aim of
providing non-invasive treatment
in neurosurgical pathologies,
including functional pathologies
such as essential tremor and
tremor associated with Parkinson's
disease where the ventral
intermediate nucleus of thalamus
has been used as a target with
proven success
}Although most treatments have
been reported with gamma knife,
radiosurgery with LINAC has also
shown successful results

4. Materialsand methods:
}Between March and April 2023 at
the Puebla Specialties Hospital of
the IMSS, radiosurgical treatment
was carried out on 5 patients with
Parkinson's disease refractory to
pharmacological medical
treatment, all with different forms
of presentations from spastic and
kinetic
}We used AlignRT

6. Results
}The dose used of 75 to 85 Gy was
given in a single session randomly,
with monthly monitoring
maintained until now. Although
the initial period to assess the
effects of radiosurgery treatment
is 8 to 10 months, at 6 months we
have observed an improvement of
at least 60% in terms of control of
involuntary movements of
patients, likewise these benefits
have been manifested in
neurological tests such as UPDRS,
Hoehn-Yahr and Scwarb-England

7. Conclusion
Conflictsof interest: no
}In subsequent months, close
monitoring will continue, waiting
for greater improvement with the
combination of pharmacological
medical treatment and waiting for
the average effect time of
radiosurgery
