Spontaneous subarachnoid hemorrhage (SAH) is a disease with high morbimortality that affects the economically active population. Its six-month mortality rate ranges from 40-50%. Knowing this reality, it is vital that every health professional (especially medical students, general practitioners, neurologists, neurosurgeons, and intensive care physicians) dominates the subject.

The Brain Aneurysm app aims to aid in learning on this complex subject. The content was developed by a team of neurosurgeons that actuate in Santa Casa de Belo Horizonte - MG (Brazil) and are members of NEUROSURGERY BLOG. It is composed by physicians: Dr. Mauro Cruz Machado Borgo, Dr. George Mendes, Dr. Lucas Alverne Freitas de Albuquerque, Dr. Julio Pereira, Dr. Pablo Seoane, Dr. Marcos Dellaretti, Prof. Dr. Gervásio Teles Cardoso de Carvalho and Prof. Dr. Atos Alves de Sousa.

The application has more than 10 figures, Neurosurgery movies, main neurological scales, and updated surgical indications to facilitate learning.

Subjects approached in the application:

1- Introduction
2- Epidemiology
3- Unruptured aneurysms
4- Aneurysms and Subarachnoid Hemorrhage
5- Types of aneurysm according to location
6- Considerations for surgical approach to intracranial aneurysms
7- Dissection of the Sylvian fissure
8- Intraoperative rupture of aneurysms
9- Brain Aneurysm Imaging
