Mini-pterional Craniotomy is a minimally invasive surgery for brain aneurysms, which maintains the advantages of the standard pterional approach, but it minimizes the exposure of brain parenchyma and soft tissue manipulation. It is a valid surgical alternative in selected cases, mainly from PComA and MCA aneurysms.

The Transcranial Doppler TCD is a useful tool for the hemodynamic monitoring of the brain when there is cerebral injury due to subarachnoid hemorrhage, it allows us to act in time, since it is a non-invasive tool that is done in the patient's bed.

In some complex aneurysms, despite endovascular treatment, there are high rates of incomplete occlusion. Penumbra coils are an efficient and cost-effective alternative to embolization in large aneurysms, with adequate packing and occlusion and with a low rate of complications.
