We describe the case of an 83-year-old woman with left-sided ophthalmoplegia. She had no family history of connective tissue disease. The computed tomography study found a dilated left cavernous sinus. The conventional cerebral panangiography confirmed the diagnosis - a direct carotid-cavernous fistula (CCF), with no evidence of ruptured aneurysm. The woman underwent endovascular treatment with coiling of the cavernous sinus in combination with application of the Onyx embolic agent in the fistula. During the first 48 hours after the embolization the local pain, exophthalmos and conjunctival injection of the left eye were significantly ameliorated...

Endovascular treatment and prognosis of intracranial aneurysms are based on size and volume, which demand more accurate neuroimaging techniques. Aneurysm volume calculation is important to choose endovascular treatment modalities and packing density calculation. Of all these methods, it remains unknown which one is the most accurate to calculate aneurysm volume. The objective of this study is to compare the accuracy of three angiography-based versus three tomographic-based methods which calculate aneurysm volume...

The Japanese population features the highest rate of elderly individuals worldwide. However, the difference of actual age indication for surgical clipping (SC) and endovascular coiling (EC) has never reported. We clarified the effect of actual age on poor outcome at discharge in patients by each treatment for ruptured cerebral aneurysm according to the Japanese Stroke Data Bank. A total of 3593 patients with ruptured saccular cerebral aneurysm were treated by SC and/or EC between 2000 and 2013. The effect of actual age on poor outcome (modified Rankin scale [mRS] score > 2) at discharge was evaluated by the cutoff age using receiver operating characteristic analysis for each treatment...

Intracranial hemorrhage is a rare complication of spinal surgery. Case 1 was a 58-year-old man who underwent cervical laminoplasty. No apparent iatrogenic dural rupture or cerebrospinal fluid leakage was observed. An hour after the surgery, the patient had convulsions and became restless thereafter. CT revealed an intracranial SAH. The patient recovered normal consciousness the next morning. Case 2 was a 68-year-old woman who underwent cervical laminoplasty without postoperative CSF leakage. Six days after the surgery, the patient continued to complain of nausea and headache...

A warning leak is a curious phenomenon attributed to cerebral aneurysms. Once the leak occurs, it has been postulated it could lead to a more catastrophic rebleeding. The designation "warning leak" trickled into neurosurgery vocabulary as early as the 1950s. The phenomenon has been poorly understood and characterized, but its presence spurs emergency physicians and neurointensivists to take action to secure the aneurysm. Rapid treatment of a recently discovered aneurysm is now commonplace, but it has not always been so...

Experimental and computational data suggest that hemodynamics play a critical role in the development, growth, and rupture of cerebral aneurysms. The flow structure, especially in aneurysms with a large sac, is highly complex and three-dimensional. Therefore, volumetric and time-resolved measurements of the flow properties are crucial to fully characterize the hemodynamics. In this study, phase-contrast Magnetic Resonance Imaging is used to assess the fluid dynamics inside a 3D-printed replica of a giant intracranial aneurysm, whose hemodynamics was previously simulated by multiple research groups...

Background: Macrovasospasms and delayed cerebral injury are factors which correlate with high morbidity in patients suffering a subarachnoid hemorrhage. Transcranial Doppler (TCD) ultrasonography and perfusion computed tomography (PCT) are diagnostic tools used to diagnose such pathologies. However, TCD is not very reliable and PCT exposes patients to radiation and cannot be performed daily. Case Description: We present the case of a 47-year-old female with subarachnoid hemorrhage caused by rupture of an intracranial aneurysm...

INTRODUCTION: Aortic intramural hematoma (IMH) is described as "dissection without intimal tear" due to rupture of vasa vasorum, which results in bleeding within the tunica media in the absence of intimal disruption or blood flow communication. The aim of our study is to validate perioperative evidence of intimal entry tear in patients with IMH and to suggest that this entity may represent a part of a disease and not a separate disease. PRESENTATION OF CASES: We report two patients admitted to our institution with sudden onset thoracic pain...

A 71-year-old woman presented with a sudden onset of headache and vomiting. Computed tomography(CT)showed diffuse subarachnoid hemorrhage(SAH)that was more severe on the right side. Three-dimensional CT angiography and right carotid angiography(CAG)demonstrated 2-mm microaneurysms at the middle cerebral artery(MCA)bifurcation and anterior communicating artery, with slight narrowing and dilatation of the M2 inferior trunk. Each microaneurysm was smooth, making it difficult to identify the bleeding source. Thus, surgery was postponed at the acute stage, and further investigation was planned...

BACKGROUND: Anterior cerebral artery aneurysms (ACAs) are characterized by higher rupture rate and small size at rupture. It was revealed that the aneurysm-to-vessel size ratio, and not the absolute size, might predict the risk of rupture in small unruptured intracranial aneurysms.The present study aimed to investigate the relationship between a size ratio and outcome in patients with unruptured non-dissecting ACA aneurysms (UNDAs). METHODS: Consecutive 187 patients with 12 A1 (6...

BACKGROUND AND PURPOSE: Hemodynamics play a driving role in the life cycle of brain aneurysms from initiation through growth until eventual rupture. The specific factors behind aneurysm growth, especially in small aneurysms, are not well elucidated. The goal of this study was to differentiate focal versus general growth and to analyze the hemodynamic microenvironment at the sites of enlargement in small cerebral aneurysms. MATERIALS AND METHODS: Small aneurysms showing growth during follow-up were identified from our prospective aneurysm database...

Indocyanine green (ICG) emits fluorescence in the far-red domain under light excitation. ICG video angiography (ICG-VA) has been established as a useful method to evaluate blood flow in the operative field. We report the usefulness of ICG-VA for Sylvian fissure dissection in patients with subarachnoid hemorrhage (SAH). Subjects comprised 7 patients who underwent ICG-VA before opening the Sylvian fissure during neck clipping for ruptured cerebral aneurysm. We observed contrasted Sylvian veins before opening the Sylvian fissure using surgical microscopes...

We report a case of subarachnoid haemorrhage resulting from a mycotic aortic aneurysm in a child with CHD. The patient previously underwent operations for CHD and had a subarachnoid haemorrhage of unknown cause before the scheduled re-operation. During the re-operation, a sealed rupture of an undiagnosed mycotic ascending aortic aneurysm was identified, and the causative organism was later identified as Streptococcus. A postoperative MRI indicated a partially thrombosed cerebral aneurysm. This case demonstrates that a mycotic aortic aneurysm can be a cause of intracranial haemorrhage in children...

BACKGROUND: Giant intracranial aneurysms (>25mm) are uncommon. These lesions typically manifest clinically due to mass effect, acute hemorrhage, or thromboembolic events. To minimize the chances of poor clinical outcome, detailed operative planning and fully integrated considerations and collaboration among neurosurgical and endovascular techniques are essential prior to microsurgical clipping of ruptured giant aneurysms. CASE DESCRIPTION: We describe a case involving a 15 year-old male with a ruptured giant middle cerebral artery aneurysm, treated with microsurgical clipping...

OBJECTIVE: Subarachnoid haemorrhage (SAH), caused by the rupture of intracranial aneurysms, is a devastating event with high rates of morbidity and mortality. Aneurysmal subarachnoid haemorrhage (aSAH) plays a critical role in the potential loss of life as its sufferers are usually of a young age. We aimed to investigate the incidence of aSAH along with the patients' characteristics over five consecutive years in Fars, a large province located in Southern Iran. METHODS: In this prospective study, anonymous data of all patients diagnosed with aSAH in Fars province were collected after patient admission and surgery...

Stereotactic radiosurgery is a well-known treatment tool for arteriovenous malformations (AVMs). The method has high validity and minimal invasiveness, but late-onset problems involving tumor formation and vasculopathy induced by radiation have been reported. We present a rare case of a radiation-induced ruptured de novo aneurysm following Gamma Knife surgery (GKS) for an AVM. A 17-year-old, right-handed male underwent GKS for AVM at the left parietal lobe. After 3 years, a follow-up angiogram showed a residual AVM at the angular gyrus...

Pure fusiform aneurysms without dissection are considered to have a low risk of rupture. Furthermore, aneurysm wall with atherosclerotic change tends to be less susceptible to rupture. We present a rare case of multiple atherosclerotic fusiform aneurysms associated with repeated subarachnoid hemorrhage(SAH)during a 9-year observation period. A 34-year-old woman was admitted to our hospital because of SAH. SAH with a temporal hematoma due to a fusiform aneurysm of the right middle cerebral artery(MCA)was detected using computed tomography(CT)...
