Large multicenter studies have shown that small intracranial aneurysms are associated with a minimal risk of bleeding. Nevertheless, other large series have shown that most ruptured aneurysms are, in fact, the smaller ones. In the present study, we questioned whether small aneurysms are indeed not dangerous.

The PHASES score was formulated to predict the 5-year risk of rupture for intracranial aneurysms. We retrospectively analyzed all patients treated in our institution for aneurysmal SAH and applied the...
Unruptured intracranial aneurysms are common incidental findings on brain imaging. Short-term follow-up for conservatively treated aneurysms is routinely performed in most cerebrovascular centers, alt...
To identify the risk factors for clinical and radiographic grades of subarachnoid haemorrhage (SAH) in small (< 5 mm) intracranial aneurysms (SIAs).
Flow diverters were popular tools for treating intracranial aneurysms in the last decade. The Derivo® embolisation device (DED) is a new-generation flow diverter designed to treat cerebrovascular ane...
In selected cases, embolization can be indicated for very small unruptured intracranial aneurysms. Previous studies reported high intraprocedural rupture rates. Recent improvements of endovascular dev...
Intracranial aneurysms are common in the general population. The overall prevalence of unruptured intracranial aneurysms (UIAs) is estimated of 2.3-3.2% in the population without specific ...
This is a prospective, multicenter, observational study, aiming at comparing the Safety and effectiveness among the different surgical treatment of unruptured intracranial aneurysms in Chi...
Atherosclerotic intracranial arterial（ICA） stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to ass...
Does Aspirin reduce inflammation in the walls of unruptured brain aneurysms? Brain aneurysms are balloon-like outpouchings of a blood vessel resulting from a weakness in the vessel wall. ...
ADPKD is the most common form of hereditary kidney disease and is known to occur in 1 of 400 to 1000 population in the U.S. ADPKD consists of 2.8% of patients receiving kidney transplantat...
Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE.

UTERINE BLEEDING from a GESTATION of less than 20 weeks without any CERVICAL DILATATION. It is characterized by vaginal bleeding, lower back discomfort, or midline pelvic cramping and a risk factor for MISCARRIAGE.
Bleeding into the SUBARACHNOID SPACE due to CRANIOCEREBRAL TRAUMA. Minor hemorrhages may be asymptomatic; moderate to severe hemorrhages may be associated with INTRACRANIAL HYPERTENSION and VASOSPASM, INTRACRANIAL.
Intracranial bleeding into the PUTAMEN, a BASAL GANGLIA nucleus. This is associated with HYPERTENSION and lipohyalinosis of small blood vessels in the putamen. Clinical manifestations vary with the size of hemorrhage, but include HEMIPARESIS; HEADACHE; and alterations of consciousness.
Bleeding within the SKULL that is caused by systemic HYPERTENSION, usually in association with INTRACRANIAL ARTERIOSCLEROSIS. Hypertensive hemorrhages are most frequent in the BASAL GANGLIA; CEREBELLUM; PONS; and THALAMUS; but may also involve the CEREBRAL CORTEX, subcortical white matter, and other brain structures.
