Subarachnoid haemorrhage (SAH) following rupture of an intracranial aneurysm is associated with a greater than 35% mortality within the first 3 months. Delayed ischaemia due to cerebral vasospasm (CVSP) occurs in approximately one-third of all patients with this disease and accounts for over 20% of its overall morbidity and mortality. ...
Vermeer S E - - 1997
BACKGROUND AND PURPOSE: Several studies have found a morning peak in onset of stroke. A similar peak has been suggested for subarachnoid hemorrhage (SAH), which seems in contradiction with the physical activities associated with aneurysmal rupture. Most studies included only a few patients with SAH. We analyzed time of onset ...
Kurokawa Y - - 1997
A 57-year-old male presented with subarachnoid hemorrhage caused by vertebral artery dissection. The first cerebral angiogram on the day of ictus found minimal caliber change with lower contrast density at the V4 segment, but repeat angiography showed typical segmental narrowing of the artery on the 14th day. Repeat angiography with ...
Kawai K - - 1997
A 19-year-old male presented with intraventricular hemorrhage manifesting as sudden onset of headache. Angiography showed mild stenotic changes in the distal internal carotid artery and proximal anterior cerebral artery only on the right. The anterior choroidal artery and lenticulostriate arteries appeared dilated, and an aneurysm-like shadow was seen in the ...
Sawin P D - - 1997
Spontaneous subarachnoid hemorrhage is usually the result of rupture of an intracranial saccular aneurysm or arteriovenous malformation. The hemorrhage is typically a cataclysmic event, heralded by severe headache, meningeal signs and neurologic dysfunction. About one-half of patients with aneurysmal rupture experience "sentinel headaches" days to weeks before a major hemorrhage. ...
Gosselin M V - - 1997
Two cases of active hemorrhage from an intracranial aneurysm demonstrated by CT angiography are presented. In each case, extraluminal opacified blood was seen entering a recent hemorrhage surrounding the aneurysm, simulating a vascular structure. This is a potential pitfall in the interpretation of CT angiograms in patients with recent subarachnoid ...

Cerebral amyloid angiopathy (CAA) is a condition characterized by amyloid deposition in cerebral blood vessels. It occurs most frequently in association with clinical Alzheimer's disease but also occurs in some nondemented elderly people. CAA is a cause of spontaneous cerebral hemorrhage and may therefore present as a sudden unexpected death ...
Fujimura M - - 1996
The incidence of chronic hydrocephalus was studied in 39 patients with subarachnoid hemorrhage, who underwent perivascular coating with fibrin glue of cerebral arteries after clipping of aneurysm. A use was made of this procedure in order to prevent vasospasm by keeping the main cerebral arteries away from direct contact with ...
German J W - - 1996
OBJECTIVE: Cerebral vasospasm is the leading cause of morbidity and mortality in patients who are hospitalized because of aneurysmal subarachnoid hemorrhage (SAH). Recent work has suggested that activation of the complement cascade contributes to the development of cerebral vasospasm. To further examine this hypothesis, a rabbit model of SAH was ...
Perona F - - 1996
The case of a 78-year-old man with retroperitoneal hemorrhage due to a ruptured right inferior suprarenal artery aneurysm is presented. The diagnosis was made by angiography which allowed immediate embolization of the neck of the aneurysm, controlling hemorrhage and obviating the need for surgery. The patient made a full recovery ...
Vermeulen M - - 1996
In this review the diagnosis and management of the acute phase of subarachnoid haemorrhage (SAH) are discussed. CT is a sensitive method of predicting a ruptured aneurysm in patients with SAH. If angiography does not reveal an aneurysm, the bleeding pattern on CT may predict if a patient is still ...
Utkan T - - 1996
We examined the effects of subarachnoid hemorrhage (SAH) and treatment with deferoxamine (DFO) or sympathectomy on vascular smooth muscle function, as well as the underlying mechanisms involved, by recording the responses to nor-adrenaline and serotonin in isolated carotid arteries in vitro. All studies were performed before and 7 days after ...

Little information exists on the utility of transcranial Doppler sonography (TCD) in detecting anterior (ACA) and posterior cerebral artery (PCA) vasospasm following subarachnoid hemorrhage. During the period at risk for vasospasm, 53 patients with subarachnoid hemorrhage who had technically adequate TCD performed within 24 hours of cerebral angiography, allowing evaluation ...
Morgan M - - 1996
This is a prospective study reporting the impact of angiographic vasospasm on the outcome following aneurysmal subarachnoid haemorrhage utilising a common regimen that includes nimodipine and angioplasty. The first 100 patients suffering an aneurysmal subarachnoid haemorrhage treated by surgery and this angioplasty driven protocol are reviewed. Angiography was performed if ...
Butler W E - - 1996
Autosomal dominant polycystic kidney disease (ADPKD) is associated with increased prevalence of cerebral aneurysms and increased risk of subarachnoid hemorrhage. A decision analysis by Levey et al. in 1983 demonstrated that patients with ADPKD would not significantly benefit from routine arteriographic screening for cerebral aneurysms. We reexamined this conclusion in ...
Lee A G - - 1996
Intracavernous carotid artery aneurysms usually cause symptoms because of gradual expansion without rupture. Most such aneurysms that do rupture lead to a carotid-cavernous fistula. Very few cases of rupture leading to subarachnoid hemorrhage have been reported. We report a case in which rupture of an entirely intracavernous carotid artery aneurysm ...
Sobel D F - - 1996
The case is presented of a 37-year-old man with spontaneous thrombosis of a 10-mm left posterior communicating artery aneurysm, following presumed subarachnoid hemorrhage with negative angiography. Sequential magnetic resonance angiography and magnetic resonance source imaging (at 2 weeks, 3 months, 2 years, and 2 years, 5 months) showed progressive shrinkage ...
Mehta V - - 1996
BACKGROUND: Acute hydrocephalus is a potentially treatable cause of early neurological deterioration after aneurysmal subarachnoid hemorrhage (SAH). METHODS: A retrospective study of 105 consecutive cases of aneurysmal SAH was undertaken to determine those factors significantly related to the development of acute hydrocephalus. Acute hydrocephalus was diagnosed when the bicaudate index ...
Hauerberg J - - 1996
Before nimodipine was introduced as a standard treatment in patients with aneurysmal subarachnoid haemorrhage (SAH) females had a significantly poorer outcome which might be due to a higher frequency of delayed cerebral ischaemia (DCI). We evaluated the overall outcome with regard to gender in 188 consecutive patients with a verified ...
Soto-Hernandez J L - - 1996
We report a case of a 32-year-old man who presented with subarachnoid hemorrhage. As revealed by lumbar puncture, the cerebrospinal fluid had low glucose, high protein levels, and pleocytosis with 5% of eosinophils. Cultures were negative. Enzyme-linked immunosorbent assay and complement fixation reactions for cysticercosis in cerebrospinal fluid were positive. ...
