Clinical significance of morphological observation of third ventricle and basal cistern with CT scan in the patients with brain contusion and laceration

Objective To study the clinical significance of observing the morphological changes of third ventricle and basal cistern on CT scanning in the patients suffering from brain contusion and laceration. Methods A prospective study was carried out on the imaging data of 126 successively hospitalized cases of brain contusion and laceration. According to the morphological changes of third ventricle and basal cisterns on the initial CT images, the 126 cases were divided into 4 groups: normal third ventricle and basal cistern group (n=33), gently compressed group (n=31), severely compressed group (n=32), absent group (n=30). The relationship between the state of third ventricle and basal cistern and the GCS score and the treatment strategies and the prognosis of patients were analyzed statistically. Results There was a significant relationship between the state of third ventricle and basal cistern and the GCS score and the treatment strategies, and the more obvious the morphological changes of third ventricle and basal cistern were, the worse the prognosis was and the higher the fatality was, and the difference was significant statistically among the 4 groups (P0.01). Conclusion There was a significant relationship between the state of third ventricle and basal cistern and the prognosis of the patients of acute brain contusion and laceration, so it can provide useful information about the patients' prognosis.
