Can silicone models replace animal models in hands-on training for endovascular stroke therapy?
CONCLUSION: Even experienced participants benefit from silicone models. Silicone models are a good preparation for animal models but cannot replace them. Categorizing participants depending on their experience and their individual needs before practical training may allow for more efficient endovascular training.

Vessel wall enhancement of a ruptured intra-nidal aneurysm in a brain arteriovenous malformation.

Accidental guide catheter fracture in mechanical thrombectomy.
We describe an unusual complication of catheter fracture and subsequent distal embolisation into the cerebral vasculature, which was noticed 24 hours after the procedure. Due to a lack of clinical consequences, we decided to manage it conservatively. The patient died within the following few days from respiratory complications unrelated to the stroke or the endovascular thrombectomy procedure. Consequently, we were able to retrieve the fractured segment and carry out histopathological analysis, which helped us to identify exactly its origin from the guide catheter.
