Video Summary

In the first video, the researchers conducted a retrospective study to investigate the association between cannabis use and delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (SAH). They found that cannabis use was independently associated with an increased risk of DCI, but there was no difference in overall clinical outcome between cannabis users and non-users. Further investigation is needed to understand the long-term impact of cannabis use in these patients.<br /><br />In the second video, a patient with comorbidities who is not a surgical candidate undergoes endovascular treatment for an aneurysm using a flow diverter. A follow-up angiogram several months later shows complete occlusion of the aneurysm, indicating a successful outcome.<br /><br />The third video discusses the development of a biomimetic endovascular device for the treatment of communicating hydrocephalus. The device mimics the function of arachnoid granulations and is placed between the cistern and the sinus to improve cerebrospinal fluid (CSF) drainage. The device has shown to be safe and effective in reducing intracranial pressure in patients with hydrocephalus. However, more research is needed to determine its suitability for all patients.<br /><br />No credits were mentioned in the provided summary.
