2/383. Carotid ligation for carotid aneurysms.Thirty patients with subarachnoid haemorrhage due to rupture of a carotid aneurysm were treated by ligation of the common carotid artery. Two patients died as a result of the procedure, two patients developed persisting hemisphere deficit. Eight of the ten patients who developed cerebral ischemia after the operation were operated within ten days after the bleeding. At present out aim is to guide the patient safely through the first ten days after his haemorrhage and perform ligation at the end of the second week. After a follow up period of 1-8 years recurrent haemorrhage did not occur. Common carotid ligation, preferably with control of carotid artery end pressure, cerebral blood-flow and EEG is considered to be a valuable method to treat ruptured intracranial carotid aneurysm.- - - - - - - - - - ranking = 49.03611012701keywords = haemorrhage, cerebral (Clic here for more details about this article) |
3/383. Sudden death in an infant caused by rupture of a basilar artery aneurysm.Ruptured aneurysms of the cerebrovasculature in infancy and early childhood, except for "giant" aneurysms and arteriovenous malformations, are rare. seizures, loss of consciousness, and apnea are the usual presenting signs in infancy; symptoms such as headache or visual disturbances and signs such as cranial nerve compression or meningeal irritation commonly found in older children or adults are absent in infants. However, the morphologic findings (i.e., subarachnoid and retinal hemorrhage, and occasionally subdural hemorrhage) may be mistaken for inflicted trauma, especially if the aneurysm is not identified. Sudden death caused by rupture of a cerebral aneurysm has not been previously described in an infant. This report outlines the investigation and autopsy findings in a 7-month-old infant who died unexpectedly as a result of rupture of a complex basilar artery aneurysm.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |

5/383. dissection of the middle cerebral artery caused by invasion of malignant glioma presenting as acute onset of hemiplegia.A 57-year-old, previously healthy man who developed acute onset of hemiplegia is presented. Neuro-imaging studies on admission suggested dissection of the middle cerebral artery producing infarction in the frontotemporal region. In contrast to his stable clinical course, serial neuro-imaging studies disclosed rapid growth of malignant glioma, which was confirmed at surgery. Microscopic examination of the surgical specimen demonstrated invasion of glioma cells into the arterial wall associated with intramural haematoma formation of the middle cerebral artery. This case is the first to document dissection of an intracranial artery caused by invasion of tumour cells.- - - - - - - - - - ranking = 6.9771889478299keywords = cerebral, haematoma (Clic here for more details about this article) |
6/383. Very late-onset symptomatic cerebral vasospasm caused by a large residual aneurysmal subarachnoid hematoma--case report.A 70-year-old female developed delayed ischemic neurological deficits at 35 days after subarachnoid hemorrhage (Hunt and Kosnik grade III, Fisher group 4) caused by a ruptured aneurysm of the left middle cerebral artery. Angiography indicated late-onset cerebral vasospasm probably due to the mass effect of a large hematoma remaining in the sylvian fissure and an intracerebral hematoma after surgery. patients with a large subarachnoid hematoma after subarachnoid hemorrhage should receive therapy to prevent cerebral vasospasm until the mass effect of the hematoma has diminished.- - - - - - - - - - ranking = 8.4259325463012keywords = cerebral, intracerebral (Clic here for more details about this article) |
7/383. Spontaneous rupture of the common carotid artery presenting as a widened mediastinum.Spontaneous rupture of the common carotid artery is an extremely rare disorder. Presentation in an elderly gentleman as a widened mediastinum with cardiac compromise has not been previously reported. Emergency surgical exploration to decompress the airway revealed a 5-mm tear just proximal to the left common carotid artery bifurcation and a large para-oesophageal haematoma. The case is reviewed and the possible causes discussed.- - - - - - - - - - ranking = 0.97718894782993keywords = haematoma (Clic here for more details about this article) |
8/383. Using transcranial Doppler sonography to augment the neurological examination after aneurysmal subarachnoid hemorrhage.Vasospasm is the leading cause of death in patients who survive initial subarachnoid hemorrhage (SAH). Evidence of blood in the subarachnoid space on computed tomography (CT) scan can often predict the occurrence of vasospasm. Clinically, the onset of new or worsening neurological symptoms is the most reliable indicator of vasospasm. Transcranial Doppler (TCD) sonography studies can further aid the neuroscience nurse's assessment for vasospasm by measuring cerebral blood flow velocities. Physiological changes that occur during vasospasm cause the lumen of the blood vessel to decrease, increasing blood flow velocity through the affected area. Although vasospasm can only be definitively diagnosed by cerebral angiogram, TCD sonography provides a noninvasive, low-risk assessment tool that can be done at the beside. By coupling a patient's vital neurological data with blood flow velocity trends, the neuroscience nurse can anticipate the onset or worsening of vasospasm. This advanced nursing assessment allows for collaboration with the medical team to initiate and adjust appropriate therapies to improve patient outcomes.- - - - - - - - - - ranking = 2keywords = cerebral (Clic here for more details about this article) |
9/383. Unilateral chronic tuboovarian abscess secondary to ruptured colonic diverticulum presenting as a brain abscess. A case report.BACKGROUND: Tuboovarian abscesses (TOAs) are a somewhat unusual finding in postmenopausal patients without risk factors. We present a rare case of unilateral TOA initially presenting as a brain abscess in a postmenopausal woman. CASE: A 61-year-old woman presented with a complaint of forgetfulness, nausea and vomiting, with lower abdominal pain and diarrhea. She was found to have a brain abscess, which was treated by craniotomy, with drainage of the abscess, and intravenous antibiotics. The patient was subsequently found to have a pelvic mass, which, on laparotomy, was a unilateral TOA. pathology demonstrated that the abscess contained vegetable matter consistent with origin in a ruptured diverticulum. CONCLUSION: diagnosis of a brain abscess should prompt a thorough investigation for a primary infectious source, including the gastrointestinal and genitourinary tracts.- - - - - - - - - - ranking = 0.020789530192253keywords = brain (Clic here for more details about this article) |
10/383. Ruptured cerebral aneurysm not detected by magnetic resonance angiography in juvenile autosomal dominant polycystic kidney.Recently, it has been reported that magnetic resonance angiography (MRA) is useful for screening and following up cerebral aneurysms in patients with autosomal dominant polycystic kidney disease (ADPKD). However, a patient was encountered with a ruptured cerebral aneurysm that was not detected by routine MRA. The patient, a 29-year-old man with ADPKD, was followed up at our hospital for more than 5 years. Ten months after an MRA examination, he suddenly developed severe headache. Brain computed tomography revealed subarachnoid hemorrhage. Digital subtraction angiography detected an aneurysm with a diameter of approximately 2 mm in the anterior communicating artery. Clipping of the aneurysm was immediately performed and he recovered without sequela after operation. magnetic resonance angiography is useful to detect cerebral aneurysms, but it can not detect aneurysms measuring less than 4 mm.- - - - - - - - - - ranking = 7keywords = cerebral (Clic here for more details about this article) |
