Cerebral aneurysm clip blades crossing during surgery is well known as scissoring. Scissoring might cause rupture of the aneurysm due to laceration of its neck. Although aneurysm clip scissoring is well known, there have been few reports describing the details of this phenomenon. Quasi-scissoring phenomenon was introduced mechanically by rotating the clip head attached to a silicone sheet. The anti-scissoring torque during the twist of the blades was measured by changing the depth and the opening width. The closing force was also evaluated...

Intracranial aneurysm is a rare cause of seizure although few cases may develop new onset seizure following rupture of aneurysm. The causes of seizure in ruptured aneurysm may be caused due to presence of subarachnoid hemorrhage, intracerebral hematoma, infarct due to progressive vasospasm, worsening of hydrocephalus, or even after surgical craniotomy for clipping of aneurysm. However, incidental aneurysm solely presenting with complex partial seizure is not reported in literature. To the best of knowledge of authors, current case represents the first case as incidental aneurysm presenting with seizure and pertinent literature is briefly reviewed...

Terson syndrome is defined as the incidence of intraocular hemorrhage in patients following a subarachnoid or intracranial bleed. A 38-year-old female with both intraretinal and subretinal hemorrhages secondary to Terson syndrome underwent repair of a ruptured cerebral aneurysm. One month following resolution of the macular hemorrhages, a paracentral scotoma persisted. Multimodal imaging (morphological and functional) confirmed the presence of acute macular neuroretinopathy Type 2 associated with deep retinal capillary ischemia...

There is limited data describing endothelial cell (EC) gene expression between aneurysms and arteries partly because of risks associated with surgical tissue collection. Endovascular biopsy (EB) is a lower risk alternative to conventional surgical methods, though no such efforts have been attempted for aneurysms. We sought (1) to establish the feasibility of EB to isolate viable ECs by fluorescence-activated cell sorting (FACS), (2) to characterize the differences in gene expression by anatomic location and rupture status using single-cell qPCR, and (3) to demonstrate the utility of unsupervised clustering algorithms to identify cell subpopulations...

Cognitive impairment is a major factor contributing to poor functional outcome after subarachnoid hemorrhage caused by a ruptured cerebral aneurysm (aSAH). Montreal Cognitive Assessment (MoCA) has been shown to be superior to the Mini-Mental State Examination in screening for cognitive domain deficit and correlating to functional outcome in aSAH patients. The aim of the current study was to determine the Montreal Cognitive Assessment (MoCA) score change that was associated with change of health in general in an aSAH patient cohort...

BACKGROUND AND PURPOSE: Anterior communicating artery aneurysm rupture and treatment is associated with high rates of dependency, which are more severe after clipping compared with coiling. To determine whether ischemic injury might account for these differences, we characterized cerebral infarction burden, infarction patterns, and patient outcomes after surgical or endovascular treatment of ruptured anterior communicating artery aneurysms. MATERIALS AND METHODS: We performed a retrospective cohort study of consecutive patients with ruptured anterior communicating artery aneurysms...

Aorto-cutaneous fistula and false aneurysm of the ascending aorta in patients who previously underwent Stanford Type A acute aortic dissection are rare and severe complications. Surgical correction remains a demanding challenge. In a case of false aneurysm rupture during redo sternotomy, selective cannulation of the right axillary and left carotid arteries allowed an efficient method of cerebral perfusion.

PURPOSE: Artificial neural networks (ANN) are increasingly applied to complex medical problem solving algorithms because their outcome prediction performance is superior to existing multiple regression models. ANN can successfully identify symptomatic cerebral vasospasm (SCV) in adults presenting after aneurysmal subarachnoid hemorrhage (aSAH). Although SCV is unusual in children with aSAH, the clinical consequences are severe. Consequently, reliable tools to predict patients at greatest risk for SCV may have significant value...

BACKGROUND: Aneurysms of meningeal middle artery (MMA) are extremely rare. These aneurysms are of two types: true aneurysm and pseudoaneurysm. The true type is usually seen with pathologic conditions. Pseudoaneurysms, on the other hand, are associated with a skull fracture. Epilepsy caused by MMA aneurysm has never been described to our knowledge. We report a case of true aneurysm isolated from MMA revealed by epilepsy. CASE DESCRIPTION: A 57-year-old patient with a history of high blood pressure developed epilepsy which was treated by valproic acid...

With modern imaging modalities of the brain a significant number of unruptured aneurysms are detected. However, not every aneurysm is prone to rupture. Because treatment morbidity is about 10% it is crucial to identify unstable aneurysms for which treatment should be discussed. Recently, new imaging tools allow analysis of flow dynamics and wall stability have become available. It seems that they might provide additional data for better risk profiling. In this study we present a new imaging tool for analysis of flow dynamics, which calculates fluid velocity in an aneurysm (Phillips Electronics, N...
