For each patient, the diagnosis was made clinically and confirmed radiologically and histopathologically. \u0000Results: Males comprised 47 percent (37) of the 80 cases, while females made up 53 percent (43). The average age was 15 (with a range of 6 – 30 years). Medulloblastomas were the most frequent pathology in 25 patients (31%), followed by ependymomas in 21 patients (26%), pilocytic astrocytomas in 19 patients (24%), and hemangioblastomas in 7 individuals (8.8%). There were four cases of metastatic brain cancers (5%), two cases of choroid plexus papilloma (2.5%), one case of ganglioglioma (1.3%), and one case of Dermoid cyst (1.3%). In 90 percent of the cases (72 cases), gross total resection was obtained, while subtotal excision was performed in 10% of the cases (8 cases). The best results were seen in pilocytic astrocytoma surgery, followed by ependymoma surgery, whereas the worst results were seen in medulloblastoma surgery. \u0000Conclusion: The surgical treatment of posterior fossa tumors still poses a significant challenge to neurosurgeons.

This study was conducted when the first author was working as PGR at LGH Lahore during 2015 to 2017. Patients were followed from admission to three-month post-op. During the follow-up, patients with clinical substantial post-op ischemic changes were calculated on CT Angiography for the presence of vasospasm. \u0000Results: Mean age of the patients was 45.23 years. Proximal TAO was done in 30% (n=25) patients. Clinically significant post-op ischemic changes were seen in 29.3% (n = 24) patients. Of the patients who underwent proximal TAO, longer occlusion time (> 10 mins) was significantly associated with ischemic changes (p-value 0.015).
