Intracranial Aneurysms

Overview of intracranial aneurysms means cerebral artery abnormalities protruding part of the spontaneous subarachnoid hemorrhage caused the most common cause. Cause is not yet very clear, but congenital aneurysms accounted for the majority. Any age can develop the disease, commonly aged 40-66. 80% occurred in the Central Cerebral Artery first half. Clinically to spontaneous intracerebral hemorrhage, cerebral vascular spasm, oculomotor nerve palsy focal characteristic symptoms. Aneurysms of the "rupture" is often severe symptoms or even death in 2001. Because diagnosis has improved tremendously, surgery and other treatment advances, Many parts of the aneurysm can be achieved good results. A clinical performance. Bleeding symptoms : aneurysm rupture is caused subarachnoid hemorrhage see the original. Performance of rapid onset, severe headache, nausea, vomiting, disturbance of consciousness and mental disorders. Meningeal irritation sign styles. Intracranial hematoma formation can produce hemiplegia and disturbance of consciousness. 2. Non-hemorrhagic symptoms : aneurysm itself to nearby nerves, blood vessels where oppression, Aneurysms more with the size and location. (1) of internal carotid-posterior communicating artery aneurysm often caused the affected artery nerve palsy, ptosis, the pupil to expand, proptosis ramps, eyesight or even decline. (2) anterior communicating artery aneurysm : often caused hypothalamus dysfunction, especially valid hemorrhage, a disturbance of consciousness, mental retardation, Gastrointestinal bleeding performance. (3) middle cerebral artery aneurysms sometimes epilepsy, hemiplegia light. (4) vertebrobasilar aneurysm can be physical asymmetric paralysis, pyramidal signs, and even appeared dysphagia, hoarseness, and other symptoms. A diagnosis. Attacks, the typical symptom of subarachnoid hemorrhage and signs. 2. Have oculomotor nerve palsy symptoms Bureau source. 3. CT can show that the hematoma and subarachnoid hemorrhage, CT and magnetic resonance angiography can show that the aneurysm. 4. Cerebral angiography can be diagnosed aneurysm location and morphology. A treatment. Medical Treatment : See "subarachnoid hemorrhage" treatment. 2. Surgical treatment : surgery craniotomy direct and indirect surgery. 3. Endovascular treatment : the aim is to introduce the endovascular embolization tumors were generated to promote tumor thrombus and occlusion. A drug. Spontaneous bleeding immediate use of 6-aminocaproic acid coagulant; Dehydrantion use of mannitol and furosemide. 2. Prevention of cerebral vasospasm : the use of nimodipine-type calcium antagonists; Blood transfusion, - albumin corrected insufficient blood volume and lower blood viscosity. 3. Antiepileptic, anti-hypertension, and other sedative treatment. 4. Symptomatic treatment and support. An auxiliary inspection. Suspected aneurysm, CT or MRI examination, especially for magnetic resonance angiography. can greatly improve diagnosis. 2. If confirmed, surgical intervention or provide evidence that the choice of cerebral angiography. to a number of vascular subtraction angiography (DSA) for good. 3. To understand the cerebral artery branches back, it has vasospasm, brain metabolism, and the option of transcranial Doppler ultrasound, Single-photon emission tomography scan or positron emission tomography. 4. Treatment process may repeat the basic inspection applications.
