Complete Information on Cerebral aneurysm or brain aneurysm

 Cerebral aneurysms are abnormal saccular outpouchings of blood vessels occurring on blood vessels of the brain. Aneurysms usually at artery branch points and may take a variety of shapes and sizes. Approximately 5% of the population may harbor brain aneurysms. Twenty percent of patients with one cerebral aneurysm will have additional aneurysms. Aneurysms usually cause medical problems by bleeding (rupture) or by putting pressure on near by brain structures. Cerebral aneurysms occur more commonly in adults than in children but they may occur at any age.

They are slightly more common in women than in men. It is estimated that people with unruptured aneurysm have an annual 1-2% risk of hemorrhage. Cerebral aneurysms have been thought to develop from weaknesses in blood vessel walls especially at branching. Smoking, high blood pressure and certain connective tissue disorders appear to promote the development of aneurysms. Less commonly, aneurysms may be traumatic in nature secondary to blood vessel injury. Infectious causes can lead to what are referred to as mycotic aneurysms. Physical exertion and use of oral contraceptives are not suspected causes for aneurysmal rupture.

Aneurysms can tear and induce bleeding in the region between the mind and the surrounding membrane called the arachnoid. Most aneurysms under ¼ inch in diameter do not rift. However, aneurysms that do rift can head to shot and death. A ruptured aneurysm frequently causes a serious worry known as a "thunderclap" worry because it comes on then abruptly. Other symptoms can include nausea, vomiting, imagination changes, apathy, failing, address disability, and seizures. Aneurysms can be treated from outside the blood vessel using postoperative techniques or from inside the blood vessel using endovascular techniques.

The two leading methods of aneurysm handling are microsurgery and endovascular operation. Microsurgical handling for aneurysms involves an available postoperative process to reveal the aneurysm by slipping under and around the mind using fragile instruments and high-power magnification. In endovascular operation, a catheter is introduced into a patient's incidental artery and navigated, using an angiogram as a "route mapping" to the region where the aneurysm is located. Once establish, the aneurysm is so filled from the interior with small platinum “coils. ” The coils respond with the surrounding blood causing it to curdle thereby obliterating the aneurysm.
