1/7. Multiple major cerebral artery thromboses with profound thrombocytopenia in acute leukaemia.A child with acute lymphoblastic leukaemia complicated by prolonged gastrointestinal and skin haemorrhages due to profound thrombocytopenia finally died of thrombotic occlusions of major cerebral arteries due to mucormycosis. biopsy of any suspect lesion is needed urgently before prolonged therapy with amphotericin b is started. So far there have been no cures in childhood.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/7. Ruptured intracranial mycotic aneurysm presenting as cerebral haemorrhage in an infant: case report and review of the literature.A 2-month-old male infant presented with intracranial haemorrhage caused by ruptured intracranial mycotic aneurysm. Computed tomography and cerebral selective angiography revealed a large haematoma in the left sylvian fissure and a mycotic aneurysm of a peripheral branch of the middle cerebral artery. Despite the successful surgical removal, the child did not recover from the initial brain injury and died 2 months later. There have been fewer than 10 reported cases of infantile mycotic aneurysms and its occurrence in the absence of infectious endocarditis is exceptionally rare.- - - - - - - - - - ranking = 5keywords = haemorrhage (Clic here for more details about this article) |
3/7. Dissecting aneurysms of the middle cerebral artery: neuroradiological and clinical features.There are few reported cases of nontraumatic dissecting aneurysms of the middle cerebral artery (MCA), and their neuroradiological and clinical features have not been analysed. We looked at these aspects in a collaborative study. We reviewed 13 patients diagnosed as having a dissecting aneurysm of the MCA based on clinical signs and neuroradiological findings in 46 stroke centres between 1995 and 1999. There were four patients who presented with cerebral ischaemia, and nine who presented with bleeding. Of the former group, three were aged less than 15 years. cerebral angiography showed extensive stenosis and a double lumen of the M1 portion in all four patients. High signal on T1-weighted images around the arterial flow void, due to intramural haematoma, was often seen in the second week. MR angiography showed findings corresponding those of intra-arterial angiography in all four cases. We saw an infarct on CT or MRI in territory of the perforating branches of the M1 segment in all four patients. In the patients presenting with bleeding, pure subarachnoid haemorrhage or a sylvian fissure haematoma was seen on initial CT, and the predominant angiographic finding was dilatation with stenosis, but the site of the lesions was not uniform. A double lumen or intimal flap was seen in about half the cases. Rebleeding occurred within 14 days of the onset in five of the nine patients, with a poor prognosis.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
4/7. Thalamic haemorrhage due to tuberculous arteritis.A young adult presenting as subarachnoid haemorrhage, which was proved to be a thalamic haemorrhage on CT scan, with evidence of tuberculous arteritis, is reported.- - - - - - - - - - ranking = 6keywords = haemorrhage (Clic here for more details about this article) |
5/7. Recovery from rheumatoid cerebral vasculitis.A 48-year-old woman with the classical features of longstanding rheumatoid arthritis acutely developed a diffuse cerebral disease. Angiograms showed extensive cerebral vasculitis, and CT scan demonstrated cerebral oedema and haemorrhage. Her clinical state, EEG and CT scan rapidly returned to normal following treatment with corticosteroids.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
6/7. cerebral revascularization.Cerebral vascular insufficiency due to occlusive lesions regarded as inaccessible is a common problem. The degree of cerebral dysfunction associated with such lesions is dependent in part on the amount of collateral circulation present. By anastomosing the superficial temporal artery to a branch of the middle cerebral artery an increase in collateral circulation is provided to the affected hemisphere. This report describes the results of twenty such procedures. Postoperative angiography demonstrates a 90% patency rate. There is frequent neurological improvement following surgery, and the rate of new TIA's or strokes seems less than would be expected. The most damaging complication of the procedure ist intracerebral haemorrhage. The indications for, and the complications of, such procedures are discussed.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
7/7. Cerebrovascular accidents resulting from segmental mediolytic arteriopathy of the cerebral arteries in young adults.Five cases of cerebrovascular accident or transient ischaemia in young adults resulting from segmental mediolytic arteriopathy are reported. The aetiology of segmental mediolytic arteriopathy is unknown but the disorder is characterized by focal, non-inflammatory mucoid degeneration of the media of muscular, non-arteriosclerotic arteries, frequently involving cerebral intracranial or extracranial vessels. It is similar to Erdheim-Gsell's medionecrosis of the aorta and may occur in any muscular artery. The consequences are mostly fatal in cerebral arteries. Histological analysis of each case is described. Clinicians should be aware of the possibility of intramural haemorrhage and dissecting aneurysm as a result of mucoid degeneration of the arterial media in young adults with cerebrovascular accident.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
