What is PCOM aneurysm?
and aneurysm of the rear road (PCOM) is a convex or balloon arterial wall in the focal area. The rear communication branches of the artery when entering the brain from the internal carotid artery and the PCOM intersection and the internal carotid artery is the most common place for PCOM aneurysm. Connection with other blood vessels to form an arterial circle on the base of the brain is the second most common place for aneurysm in this Willis circle, which is about 30 percent of brain aneurysm. The most common causes of PCOM aneurysm include hypertension, atherosclerosis, congenital malformations and trauma. There are three classifications of aneurysms - saccular, fusiform and autopsy.
Investigators estimate that one to six percent of people will suffer from brain aneurysm. The brain aneurysm may occur at any age, but in adults it is more common, with women are more affected than men. Aneurysms may occur more frequently in conjunction with health such as polycystic kidney disease, disorderChy connective tissue and fibromuscular dysplasia. When aneurysms are examined under a microscope, the arterial wall lacks a normal center, a muscle layer called the media. The inner aneurysm opening often contains a blood clot.
PCOM aneurysm may not have any symptoms at all. Patients may report serious headache, stiff neck, nausea, vomiting and visual impairment before pre -rupture of aneurysm. In some cases, the patient may lose consciousness. Aneurysm rupture results in brain bleeding or brain lining with a sudden onset of symptoms. The risk of aneurysm rupture is about 1.3 percent per year in the United States.
Oculomotoric Nerve Palsy is a remarkable character specific to PCOM aneurysm. The oculomotor nerve provides the nerve supplies of the muscles that live the lid and move the eye up, down and inward. In addition, the nerves that reduce the pupil in a bright light, with an oculomotornerve. If the patient has oculomotor palsy, he will have the undulating upper lid, a double vision, a deviated eye that moves incorrect and perhaps a large non -responding pupil. Patients with these symptoms should undergo immediate brain display to look for PCOM aneurysm.
Treatment of cracked PCOM aneurysms primarily involves stabilizing the patient's breathing and lowering pressure on the brain. In addition to medical management, doctors can continue to crop aneurysm or by placing a coil in aneurysm to engage and minimize the risk of repeated bleeding. The location of the coil allows a faster recovery in the patient, but is associated with a slightly higher recurrence rate than cropping. The risks of both procedures occur at approximately the same speed.
