dc.description.abstractBACKGROUND: We wanted to investigate the somatotropic reorganization occurring in the motor and somatosensory cortex by using 99mTc-HMPAO SPECT analyses, after the extremity revascularization, replantation or amputation. METHODS: Twelve patients (11 men, 1 female; mean age 38.9±14.7 years) and controls (5 men, mean age 32.2±7.9 years) were enrolled in this study. After reconstruction, lower, middle and upper orbitomeatal slices with precentral and postcentral slices were obtained. All images were visually and semi-quantitatively evaluated. Mann-Whitney U-test was used for statistical analysis. RESULTS: In the revascularization and replantation patients, postcentral and precentral hypoperfusions were seen at dominant hemisphere. In the amputated patients, postcentral (in 3 of 4 cases) and precentral hypoperfusions were seen at non-dominant hemisphere and postcentral hypoperfusion (in 1 of 4 cases) was seen at dominant hemisphere. In our patients, most significant difference in regional cerebral blood flow was found in posterior parietal cortex (somatic associated area). CONCLUSION: Changes that take place in precentral and postcentral cortical areas subsequent to the extremity replantation-revascularization of the organ is a good indicator of somatotrophic reorganization.en_US
