| Description | Introduction Transcallosal approach belongs to important neurosurgical approaches and is being used mainly for the processes of the III rd and lateral ventricles. The approach might be used either for extraaxial ventricular tumors but also for intraaxial tumors like thalamic gliomas. The approach has its peculiarities and risks – injury of pericallosal arteries or venous congestion from cutting the briging veins or the fornix and deep venous injury. In this paper we discuss the technical aspects of this approach as well as the treatment results. Material: During 2005 to 2024 we used this approach in 51 patients with histologically diverse lesions. The most frequent were thalamic pilocytic astrocytomas (15 patients) and 8 craniopharyngeomas. There were 7 colloid cysts, 3 metastases, 3 glioblastomas, 3 subependymomas, 2 germ cell tumors and one ependymoma, schwannoma, cavernoma, plexus papilloma, ganglioglioma, diffuse low grade glioma, anaplastic pleomorphic xanthoastrocytoma, central neurocytoma and subependymal giant cell astrocytoma. Results: Tumor was totally removed in 24 cases, 18-times the resection was subtotal (more than 90%) and in 9 patients there was only partial resection (less than 90%). 34 patients had a good treatment results, in 11 cases there was a transient neurological deficit (6 cases of mild hemiparesis and 5 cases of a transient memory deficit) and 5 cases of permanent neurological deficit (severe hemiparesis). One patient after a partial resection of a metastasis died due to a hemocephalus. Conclusion: Transcallosal approach should belong to an armamentarium of a neurosurgeon dealing with ventricular tumors and other midline tumors. There are situations where the use of transcallosal approach seems to be a really the best option, specifically compared to transcortical approaches. It is necessary, however, to take into consideration the risks of this approach, mainly the damage to venous system and the fornices. |
