Every year 200,000 to 250,000 people get affected by a stroke in Germany. Approximately 1,000,000 people suffer from the results of this disease. It represents the third most frequent cause of death, after heart attacks and cancer.

In Western countries, the most difficult lifelong handicaps account for about 5% of the entire health costs. This economic burden, caused by extremely high treatment and care expenses, is enormous. Hemorrhages in the area of the brain or the brain tissues are designated as a ‘Hemorrhagic stroke’; this accounts for approximately 20% of strokes.

A brain hemorrhage is caused most frequently by an innate or acquired brain vessel anomaly, more rarely caused by trauma or other causes.

An aneurysm represents a special form of anomaly. It concerns a spindle- or sack-shaped expansion of an artery. If it comes to a tear in the aneurysm wall (a rupture), the emerging blood will cause brain damage.

State-of-the-art medical practice not only allows treatment of ruptured aneurysms, but also enables recognition and locking of an aneurysm before the appearance of a stroke. A brain bleeding, and therefore severe mental and physical consequences for the patient, can be avoided.
