Abstract:

Purpose: It is intended to determine early surgical results and complication rates, along with clinical and radiological findings of children who are placed in the neurochirurgical clinic due to bacterial cavity tumors. Method: Data of patients under the age of 18 who were diagnosed with malign posterior fossa tumor in our clinic between 2011 and 2020 were scanned. The demographic characteristics of patients, complaints, clinical findings, surgery, pathological results and complications were noted. Pre- and post-operation screening methods have been examined. The location of the tumor, the presence of the remaining tumor, was examined whether it was hydrosphaly or not. The findings: Thirty-three patients were identified, the average age of these children was 7. Among the applications, the highest number of headaches (57.6%) and imbalance (48.5%) were. Papillodem, ataksi and nistagmus were on the forefront. Before the operation, 6 patients had cranial nerve paralysis and 3 patients had hemiparesis. Pre-operative hydrosphaly was 66.7%. The most common tumor was medulloblastoma (39.4 percent). The rate of high-degree tumors in the operated tumors was 66.7%. Seven of the tumors in the recession were inflicted in the brain. Twenty-four patients had a tumor recession, 12 of which provided total removal. Patients with diffuse pontin gliom have not been performed surgery. 30.3 percent of all patients were diagnosed with external ventricular drainage (EVD). Only 4 of them needed V-P (ventriculoperitoneal) chant. In high-degree tumors, the rate of development of any surgical complication was higher than in low-degree tumors (p=0,038). In total removed tumors, the rate of complications was also higher (p=0,034). The most common complication was BOS fistula (16.7 percent). Three patients with EVD had signs of infection. Three patients had a hematoma in the tumor lotion. Two patients without EVD (8.3%) developed hydrosphaly and these patients were infected with V-P shant. Four of the six patients in the shant had blood in the ventricle after surgery. Two patients who have not previously had a weakness developed hemiparesis after surgery. Three patients (12.5 percent) had mutism and one had disarthria. Two patients developed pneumonia during intensive care follow-up and one of these children was lost in the second month after the surgery. The result: In childhood back hole tumors, the presence of a high degree of tumor, the invasion of the cerebrovascular discharge, the total removal of the tumor and the risk of complications in the ventricle after surgery increases.
