| Summary: |
Uveal melanomas, even
those of big size, are recently more readily treated
conservatively, with radiotherapy, though the efficiency
of this treatment has not been yet estabilished.
Purpose: Of the study was the assessment of the
usefulness of Color Doppler (CD) or Power Doppler (PD)
examination in monitoring the effectivity of
brachytherapy in the management of melanomas.
Material and methods: Examination was performed in 15
patients, who were treated because of medium size or
large uveal melanomas, with plaque radiation (brachytherapy).
CD/PD examination of blood flow within the tumor, with
the use of SonoVue contrast agent in several cases, was
performed before institution of the therapy and two
times after the treatment, as follow-up.
Results: Regression of the tumor and gradual atrophy of
its neovascularisation was observed in all the examined
patients. The enhancement of Color Doppler imaging with
contrast agent helps in making decision to further
therapeutic options as complex situation.
Conclusions: Color and Power Doppler ultrasonography is
a helpful method in monitoring the effectivity of
brachytherapy in patients with uveal melanomas. |
