1/263. 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 = 1keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
2/263. Ruptured anterior spinal artery aneurysm: a case report.BACKGROUND: Spinal artery aneurysms are rare, and are usually found in association with arteriovenous malformations or coarctation of the aorta. CASE REPORT: A 42-year-old man with a ruptured anterior spinal artery aneurysm is presented here. He experienced subarachnoid hemorrhage, which was confirmed by computed tomography. magnetic resonance imaging revealed an aneurysm in front of the upper part of the medulla. Angiography demonstrated bilateral vertebral artery occlusion. Distal vertebral arteries and the basilar artery were perfused via the dilated anterior spinal artery, which originates in the right subclavian artery. The aneurysm was located at the distal part of the anterior spinal artery, and was successfully clipped through a lateral suboccipital craniotomy 2 months after bleeding from the aneurysm. After rehabilitation, the patient was able to walk with no apparent neurologic deficit. CONCLUSIONS: This case suggests that the anterior spinal artery as a collateral route after bilateral vertebral artery occlusion is under hemodynamic stress, resulting in aneurysm formation and rupture.- - - - - - - - - - ranking = 0.14535584995482keywords = subarachnoid (Clic here for more details about this article) |
3/263. 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 = 0.14535584995482keywords = subarachnoid (Clic here for more details about this article) |
4/263. Spontaneous ventriculostomy: report of three cases revealed by flow-sensitive phase-contrast cine MR imaging.Spontaneous ventriculostomy is a rare condition that occurs with the spontaneous rupture of a ventricle, resulting in a communication between the ventricular system and the subarachnoid space. Three cases of spontaneous ventriculostomy through the floor of the third ventricle that occurred in cases of chronic obstructive hydrocephalus are presented. The communication was identified via flow-sensitive phase-contrast cine MR imaging. Spontaneous ventriculostomy is probably a result of a rupture of the normally thin membrane that forms the floor of the third ventricle and, with long-standing obstructive hydrocephalus, creates an internal drainage pathway that spontaneously compensates for the hydrocephalus.- - - - - - - - - - ranking = 0.14535584995482keywords = subarachnoid (Clic here for more details about this article) |
5/263. 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 = 1.0174909496837keywords = subarachnoid (Clic here for more details about this article) |
6/263. Cardiac arrhythmia as initial presentation of aneurysmal subarachnoid hemorrhage.Cardiac arrhythmia and sudden death are most frequently caused by preexisting heart disease. Rarely, cardiac arrhythmia is a first symptom of an acute neurological event. We describe a patient with asystole and other cardiac arrhythmias, as initial symptoms of acute aneurysmal subarachnoid hemorrhage. Several aspects of cardiac arrhythmias and acute aneurysmal subarachnoid hemorrhage are discussed.- - - - - - - - - - ranking = 0.87213509972891keywords = subarachnoid (Clic here for more details about this article) |
7/263. 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 = 0.87213509972891keywords = subarachnoid (Clic here for more details about this article) |
8/263. 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 = 0.14535584995482keywords = subarachnoid (Clic here for more details about this article) |
9/263. Ruptured intracranial dermoid cyst.Intradural dermoids are rare congenital tumors representing approximately 0.05% of all intracranial lesions. These benign tumors have a typical appearance on CT and MR due to their lipid components. The complication caused by rupture are the spillage of the fatty material into the cerebrospinal fluid. We report a case of a ruptured dermoid cyst showing fat/fluid levels in both side ventricles and fatty material in the subarachnoid space on CT and MR-imaging and the follow-up over four years after incomplete resection of the tumor.- - - - - - - - - - ranking = 0.14535584995482keywords = subarachnoid (Clic here for more details about this article) |
10/263. Active contrast extravasation in spontaneous rupture of hepatocellular carcinoma: a rare CT finding.Spontaneous rupture of hepatocellular carcinomas are uncommon but constitute a critical and life threatening condition. diagnosis is important so that either surgery or emergency arterial embolisation can be considered for hepatic haemostasis. We describe active extravasation of intravenous contrast medium on CT in a patient who presented with intraperitoneal haemorrhage secondary to spontaneous rupture of hepatocellular carcinoma.- - - - - - - - - - ranking = 0.10122646071354keywords = haemorrhage (Clic here for more details about this article) |
