Introduction: Haemostasis in brain surgery is mandatory to avoid postoperative re-bleeding and a poor outcome. Postoperative intra-cavity haemorrhage is a frequent complication, especially in surgery of malignant gliomas because of the fragility of pathological vessels. Material and methods: In this technical note, we describe our 'compression' technique used to achieve haemostasis in adult patients who underwent surgery for supratentorial malignant gliomas (GBM) at our Institute from January 2019 to January 2022. Peri-operative work-up included clinical status, laboratory data and contrast brain CT, performed at 24 hours after surgery, or earlier for patients with neurological worsening. Results: A total of 82 patients was included in this study, 46 males (57%) and 36 females (43%). A post-operative intra-cavity haemorrhage was documented by postoperative CT-scan in 3/82 patients (3.65%), and the mean surgical time was 3.66 hours. No late bleeding was observed 48 hours after surgery. Conclusions: We have documented the good results of our technique to achieve haemostasis in patients operated for malignant glioma (GBM). The technique described in this study seems to be safe and useful to avoid post-operative bleeding in the surgery of cerebral GBM.
