Abstract |
Background |
In the era of endovascular treatment of intracranial aneurysms, surgical clipping is still a relevant treatment method in some cases. However, it has become harder to teach this skill, as the number of surgical cases has decreased over the past years. We therefore decided to use a previously described experimental aneurysm model for surgical training.
Material and methods |
We operated on 8 rats and constructed a vein-pouch aneurysm at a surgically created carotid bifurcation. Survivors were kept alive for 1 month and operated on to clip the aneurysm.
Results |
Only 3 rats had survived at 1 month. All the carotid arteries were permeable. Only 2 aneurysms were circulating at 1 month, as 1 had thrombosed. They were successfully clipped at 1 month.
Conclusions |
These preliminary results enabled our junior surgeon to clip two circulating aneurysms, under an operative microscope reproducing surgical conditions. Although the efficacy of the model could be improved, we believe it could be used as a first step in training neurosurgical residents in the basics of aneurysm clipping and microsurgical techniques in a realistic setting.
