What is an aneurysm?

Understand what is an aneurysm

According to studies by some members of the Brazilian Academy of Neurosurgery, Intracranial Aneurysms are dilations of cerebral blood vessels that have a potential risk of rupture

Which leads to a subarachnoid hemorrhage (SAH). This is a fatal condition, thus causing that about 12% of the patients affected by it, die before getting medical care and, about 40%, die within one month after the incident.

Moreover, many patients who survive to the  rupture of an aneurysm remain with sequelae, which results in problems of environmental and social adaptation, as well as the decrease in quality of life. It is estimated between 2% and 5% prevalence of cerebral aneurysms in the adult population, with a rupture rate of approximately 0.7% to 1.4% per year. Although the mortality due to aneurysm rupture has decreased, the prevalence of HSA has been constant over the years, with an estimated rate of 1 per 10,000 inhabitants per year.

The Implantable Intracranial Clips for cerebral aneurysm, the Aneurysm Clips, are devices used solely for closing and / or isolation of veins and / or arteries due to Cerebral Aneurysms in human beings.

The pathogenesis of cerebral aneurysms is still little known. It is known that the formation of these saccular dilations is related to the loss of integrity of the connective tissue surrounding the vessel wall and the tunica degeneration. Since this is a multifactorial disease, pathogenesis is related to a number of predisposing factors acting at the same time. Interaction occurs between between genetic predisposition and environmental and behavioral factors, increasing the risk of developing aneurysms.

It is still a small number of cases of aneurysm diagnosed before rupture. Most of the time the patient learns that was affected by a Cerebral Aneurysm after stroke. To confirm the previous diagnosis to stroke are needed tests such as computed tomography and cerebral angiography. Today there are a number of advanced and less invasive tests to ensure early diagnosis.

For “clipping” of the aneurysm – implantation of a clip – is required prior diagnosis to disruption or prior to hemorrhagic committal process. The implant of intracranial cerebral aneurysms clips, through a surgical procedure, is one of the best ways for the prevention of a stroke.
