1/3. Cerebral aneurysms of traumatic origin.This report reviews 41 cases of traumatic cerebral aneurysms, including four cases of our own which are presented in detail. They may follow penetrating or closed head injury, and are usually associated with significant additional intracranial damage. Almost half of the patients presented with a delayed subarachnoid hemorrhage within three weeks of the initial head injury, defining an important neurological syndrome. Those patients whose post-traumatic aneurysms have been surgically obliterated have an associated mortality which is half that of patients treated by nonsurgical methods.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/3. Inflammatory aneurysm due to neurocysticercosis.A 69-year old man presented with a subarachnoid hemorrhage associated with a large intracerebral hematoma in the right temporal lobe. The oblique views of cranio-orbital computerized tomographic angiography (CTA) were suspicious for an aneurysm on a middle cerebral artery branch. At surgery, a cystic mass was found in the Sylvian fissure, associated with an aneurysm on a distal branch of the anterior temporal artery. The aneurysm was not situated at a bifurcation of the artery and was located beneath the cyst. It was secured by trapping. Pathological examination revealed that the cystic lesion was neurocysticercosis and that the aneurysm was inflammatory. We report a ruptured inflammatory aneurysm of a distal branch of the anterior temporal artery associated with neurocysticercosis, and present the histological findings. We believe this is the first report of such an inflammatory aneurysm with histological confirmation.- - - - - - - - - - ranking = 1.6666666666667keywords = aneurysm (Clic here for more details about this article) |
3/3. Improvement after treatment of hydrocephalus in aneurysmal subarachnoid haemorrhage: implications for grading and prognosis.Two patients with aneurysmal subarachnoid haemorrhage and hydrocephalus are presented. On admission they scored E1M4V1 and E1M3Vtube on the glasgow coma scale. The first patient recovered to E3M5Vtube after treatment of hydrocpehalus by extraventricular drainage. The second recovered to E2M5Vtube and later E4M6V4 after treatment of hydrocephalus with lumbar drainage. Based on the literature it is argued that these cases are no exception as to the improvement after treatment of hydrocephalus. The prognosis of patients with hydrocephalus after a subarachnoid haemorrhage, improves in parallel with the glasgow coma scale after treatment of hydrocephalus. Therefore decision making on whether or not to treat a patient with a subarachnoid haemorrhage should be postponed until after treatment of hydrocephalus, if present.- - - - - - - - - - ranking = 0.83333333333333keywords = aneurysm (Clic here for more details about this article) |
