1/246. Giant fusiform aneurysm of the middle cerebral artery: successful Hunterian ligation without distal bypass.Giant fusiform aneurysm is a rare vascular lesion which presents difficult management issues. We describe one such aneurysm in a middle cerebral artery branch (M2) that presented with subarachnoid haemorrhage and was managed operatively. Clinical, radiological and pathological presentations, as well as the different treatment options for this type of aneurysm are discussed based on a literature review. A satisfactory results in an M2 giant fusiform aneurysm can be achieved with Hunterian ligation of the parent vessel even when a distal EC-IC bypass is not possible.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/246. Intra-arterial infusion of fasudil hydrochloride for treating vasospasm following subarachnoid haemorrhage.In this pilot study we treated cerebral vasospasm in patients with subarachnoid haemorrhage to assess intra-arterial fasudil hydrochloride. We analysed effects of intra-arterial infusion on angiographically evident cerebral vasospasm in 10 patients including 3 with symptoms of vasospasm. Over 10 to 30 min 15 to 60 mg was administered via the proximal internal carotid artery or vertebral artery following standard angiography, without superselective techniques. A total of 24 arterial territories (21 internal carotid, 3 vertebral) were treated. Angiographic improvement of vasospasm was demonstrated in 16 arterial territories (local dilation in 2, diffuse dilation in 14) in 9 patients. In 2 symptomatic patients, intra-arterial fasudil hydrochloride was associated with resolution of symptoms without sequelae. In the third symptomatic patient the benefit of fasudil hydrochloride was only temporary, and a large cerebral infarction occurred. All asymptomatic patients showed no progression of angiographic to symptomatic vasospasm after treatment with intra-arterial fasudil hydrochloride. No adverse effect was encountered.- - - - - - - - - - ranking = 5keywords = haemorrhage (Clic here for more details about this article) |
3/246. Subarachnoid haemorrhage: difficulties in diagnosis and treatment.Aneurysmal subarachnoid haemorrhage is associated with a uniquely severe headache of acute onset. Classical cases are readily identified as such, although this is not always the case. Four cases who were admitted to a district general hospital within a 3-month period are presented, because they demonstrate a variety of presentations, management options, and outcomes.- - - - - - - - - - ranking = 5keywords = haemorrhage (Clic here for more details about this article) |
4/246. Systemic lupus erythematosus, berry aneurysm and subarachnoid haemorrhage.A 57-year-old woman with SLE and subarachnoid haemorrhage is described.

5/246. Lumbar spinal subdural hematoma following craniotomy--case report.A 52-year-old female complained of lumbago and weakness in the lower extremities 6 days after craniotomy for clipping an aneurysm. Neurological examination revealed symptoms consistent with lumbosacral cauda equina compression. The symptoms affecting the lower extremities spontaneously disappeared within 3 days. Magnetic resonance (MR) imaging 10 days after the operation demonstrated a lumbar spinal subdural hematoma (SSH). She had no risk factor for bleeding at this site, the symptoms appeared after she began to walk, and MR imaging suggested the SSH was subacute. Therefore, the SSH was probably due to downward movement of blood from the cranial subdural space under the influence of gravity. SSH as a complication of cranial surgery is rare, but should be considered if a patient develops symptoms consistent with a lumbar SSH after craniotomy.- - - - - - - - - - ranking = 3.9315836258678keywords = subdural (Clic here for more details about this article) |
6/246. Ruptured distal anterior choroidal artery aneurysm presenting with casting intraventricular haemorrhage.This report describes a rare case of a distal anterior choroidal artery aneurysm which developed intraventricular haemorrhage without subarachnoid haemorrhage as shown on computerized tomographic (CT) scan. A 69-year-old hypertensive man suddenly became unconscious. An emergency CT scan showed a severe intraventricular haemorrhage and a small round low-dense lesion within the haematoma at the right trigone. The haematoma with obstructive hydrocephalus made the lateral ventricles larger on the right than on the left. CT scan could not detect any subarachnoid haemorrhage. Right interal carotid angiography revealed a saccular aneurysm at the plexal point of the right anterior choroidal artery. We approached the aneurysm and the small round lesion through the trigone via a right temporo-occipital corticotomy. We could clip the aneurysmal neck and remove the intraventricular haematoma and the papillary cystic mass (corresponding to the small round lesion on CT scan) totally in one sitting. Histological examination revealed the aneurysm to be a true one and the papillary cystic mass to be a choroid plexus cyst.- - - - - - - - - - ranking = 9.1443261237383keywords = haemorrhage, haematoma (Clic here for more details about this article) |
7/246. Multiple intracranial aneurysms in polyarteritis nodosa: MRI and angiography.In polyarteritis nodosa involvement of the central nervous system is infrequent; small cerebral infarcts are the most common neuroradiological finding. We report a 10-year-old boy with polyarteritis nodosa and intracranial haemorrhage. MRI showed an intracerebral haemorrhage. angiography revealed two peripheral aneurysms in the posterior cerebral circulation, previously reported on only two occasions, and multiple microaneurysms in the hepatic, renal, mesenteric and even the lumbar arteries.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
8/246. Intracystic hemorrhage of the middle fossa arachnoid cyst and subdural hematoma caused by ruptured middle cerebral artery aneurysm.We report a case of a cerebral aneurysm arising from the bifurcation of the left middle cerebral artery that ruptured into a left middle cranial fossa arachnoid cyst, associated with acute subdural hematoma. We discuss the relationships of aneurysm, arachnoid cyst, and subdural hematoma.- - - - - - - - - - ranking = 3.9315836258678keywords = subdural (Clic here for more details about this article) |

Ruptured aneurysm at the trunk of the accessory middle cerebral artery.We present a 32-year-old woman with intracranial haemorrhage due to rupture of a saccular aneurysm arising from the trunk of an accessory middle cerebral artery.

10/246. Distal calcarine fusiform aneurysm: a case report and review of literature.A 50 year old female who was operated for atrial septal defect 8 years back, presented with clinical features suggestive of subarachnoid haemorrhage (grade I, Hunt and Hess). CT scan of brain revealed haemorrhage in all the supratentorial basal cisterns, sylvian cistern and small haematoma in the left occipital lobe. Conventional CT and MR angiography revealed aneurysm in relation to distal part of the calcarine branch of the left posterior cerebral artery (PCA). Left occipital craniotomy in prone position followed by deep dissection in the occipital lobe showed fusiform aneurysm of the distal part of the calcarine branch. PCA aneurysms constitute only 0.2 to 1% of all intracranial aneurysms and among them distal PCA aneurysms are most rare, constituting only 1.3%. They too are mostly seen at the bifurcation of the PCA. The present case however, is unique in the sense that it has developed as a fusiform aneurysm in the distal part of the calcarine branch. To the best of our knowledge this is rare among the rarest.- - - - - - - - - - ranking = 2.3814420412461keywords = haemorrhage, haematoma (Clic here for more details about this article) |
