Background: Burr hole evacuation is a well-established treatment for symptomatic cases with chronic subdural hematoma (cSDH). Routinely postoperative catheter is left in the subdural space to drain the residual blood. Drainage obstruction is commonly seen, and it can be related to suboptimal treatment. Methods: Two groups of patients submitted to cSDH surgery were evaluated in a retrospective non-randomized trial, one group that had conventional subdural drainage (CD group, n ​= ​20) and another group that used an anti-thrombotic catheter (AT group, n ​= ​14). We compared the obstruction rate, amount of drainage and complications. Statistical analyses were done using SPSS (v.28.0). Results: For AT and CD groups respectively (median ​± ​IQR), the age was 68.23 ​± ​26.0 and 70.94 ​± ​21.5 (p ​> ​0.05); preoperative hematoma width was 18.3 ​± ​11.0 ​mm and 20.7 ​± ​11.7 ​mm and midline shift was 13.0 ​± ​9.2 and 5.2 ​± ​8.0 ​mm (p ​= ​0.49). Postoperative hematoma width was 12.7 ​± ​9.2 ​mm and 10.8 ​± ​9.0 ​mm (p ​

Abstract  We report a 65 year old man who presented with left hemiparesis, and was found to have multiple, discrete, peripherally enhancing, hemorrhagic intra-axial masses in the right hemisphere of the brain. Workup for malignancy elsewhere in the body was negative, and biopsy confirmed glioblastoma multiforme. The patient responded clinically to treatment with radiation therapy and temozolomide. We discuss the unusual aspects of this case and stress the importance of tissue diagnosis in managing suspected intracranial malignancies. [ABSTRACT FROM AUTHOR]
