Cerebral aneurysm is a blood-filled bump in a vessel. Pathology is asymptomatic in the body until it blows out. When an aneurysm bursts, a person feels a heavy headache – often it leads to death.
A vessel succumbed to blood pulsation pressure is rather weak. It causes formation of blister kind in one of its sections. During blood rush to aneurysm, it strains, increasing. When it bursts, blood enters right into the brain, provoking damages.
Scientists can’t say why aneurysm appears in brain. However, there are some factors having weakening effect on vessels:
In addition, following categories of people are prone to have this pathology:
If close relatives had aneurysm, neurosurgery specialists recommend to conduct diagnosis with others. Risk is much higher if there are also associated defects.
Any process raising blood pressure leads to aneurysm rupture, in particular:
Most common symptom of aneurysm cerebral is strong headache. Other warning signals:
A ruptured aneurysm shows up:
Aneurysm can be diagnosed using CT, MRI, and diagnostic cerebral angiogram. Additionally, sometimes doctors use MRA and computed resonance angiography. Through such methods, aneurysm sizes can be accurately determined.
Blown out pathology may not be visible on tests. However, if symptoms are obvious, doctor prescribes spinal cord puncture.
Cerebral aneurysm treatment includes such methods.
People can live for many, many years with intact aneurysm. Burst pathology has great danger. In case of rupture, person needs prompt medical reaction. If medical care is not provided, death from aneurysm cerebral rupture is likely in 75% of cases. A quarter of patients who have been assisted may also face fatal complications within six months.
