The study included 562 patients with headache who visited our clinic from January 1988 to December 1993. In these patients, the possibility of subarachnoid hemorrhage was denied from CT findings and color of cerebrospinal fluid by lumbar puncture. Cerebral aneurysm was found in 52 out of 562
One third of patients with aneurysmal subarachnoid haemorrhage (ASAH) present with headache only. A prompt diagnosis is crucial, but these patients must be distinguished from patients with non-haemorrhagic benign thunderclap headache (BTH). The headache characteristics and associated features at
Severe headaches, projectile vomiting, focal neurological deficits and early onset seizure are regarded as early warning symptoms of subarachnoid hemorrhage (SAH). Earlier diagnosis based on such warning symptoms theoretically would improve the clinical prognosis. However, it is still OBJECT.: When patients present to the emergency department (ED) with acute headache concerning for subarachnoid hemorrhage (SAH) and a lumbar puncture (LP) shows blood in the CSF, it is difficult to distinguish the results of a traumatic LP from those of SAH. CT angiography (CTA) is often performed,
Thunderclap headache is a sudden, high-intensity headache often associated with subarachnoid hemorrhage secondary to a ruptured intracerebral aneurysm. A variety of less common causes have now been described. This report presents the cases of 2 patients who experienced thunderclap headache after
OBJECTIVE
Forty percent of patients with aneurysmal subarachnoid hemorrhage have prodromal warning episodes and difficulties in identifying these events are repeatedly documented. Modifications of diagnostic and referral patterns through educational programs of local doctors may help to identify
OBJECTIVE
The objective was to determine the incidence of subarachnoid hemorrhage (SAH) diagnosed by lumbar puncture (LP) when the head computed tomography (CT) was reported as demonstrating no subarachnoid blood.
METHODS
Data were obtained on patients who received LP to diagnose or exclude SAH
OBJECTIVE
The most common symptom associated with aneurysmal minor bleed ("warning leak") is a sudden agonizing headache. Early screening of these patients may improve the outcome of subarachnoid hemorrhage and may be highly cost-effective.
METHODS
We conducted an extensive retrospective audit of
Nationwide cost and benefit was estimated for performing computed tomography (CT) on headache patients in the hope of discovering a specific finding, subarachnoid hemorrhage. Case finding costs were estimated using a previously published survey of CT use at a university hospital where, of 258
OBJECTIVE
Some patients report the absence of a typical headache at the onset of subarachnoid hemorrhage (SAH). We investigated the clinical backgrounds and characteristics of patients with SAH without headache and compared the findings with those of patients with SAH and headache.
METHODS
We
OBJECTIVE
The necessity of cerebral angiography was assessed in patients with thunderclap headache in whom subarachnoid hemorrhage had been ruled out on CT findings and the color of cerebrospinal fluid (CSF).
METHODS
The subjects of this study were 350 patients with thunderclap headache in whom
BACKGROUND
The headache preceding an intracranial aneurysm rupture is called a sentinel headache (SH), and it is characterized by a sudden, intense, and persistent headache. As subarachnoid hemorrhage (SAH) often develops within several weeks of SH, its rapid diagnosis and treatment can improve the
OBJECTIVE
The clinical significance of sentinel headaches in patients with subarachnoid hemorrhage (SAH) is still unknown. We investigated whether patients with a sentinel headache (SH) have a higher rate of rebleeding after SAH.
METHODS
An SH was defined as a sudden, severe, unknown headache
We report a case of a 31-year-old female with multiple intracerebral hemorrhage and subarachnoid hemorrhage. She presented with headache one week before hemorrhage, and a CT scan performed at that time showed no abnormal findings. Neurological examination on admission revealed mild disturbance of
Retrospective surveys of patients with subarachnoid haemorrhage suggest that minor episodes with sudden headache (warning leaks) may precede rupture of an aneurysm, and that early recognition and surgery might lead to improved outcome. We studied 148 patients with sudden and severe headache
