OBJECTIVES: No valid treatment modality that will repair stroke damage and provide neurological recovery has yet been identified in literature. Studies demonstrated that adequate quality of life could be provided if post-stroke pain could be treated sufficiently and timely. Besides its pain relief effects, tramadol has oedema-reducing and anti-inflammatory properties. With these in mind, this study investigated the influence of tramadol in acute and/or chronic ischaemia/reperfusion (I/R) injury...

BACKGROUND AND IMPORTANCE: Aneurysms of the ophthalmic artery (OA) within the orbit and optic canal are extremely rare. Given the peripheral location of these aneurysms and the fact that most are fusiform, parent artery occlusion is preferred for symptomatic aneurysms. However, the impact of OA occlusion on vision is not always innocuous. Balloon occlusion testing (BOT) of the OA has the potential to gauge the possibility of visual compromise, in addition to assessing collaterals. While BOT has been assessed for carotid artery occlusion, its role in OA occlusion has not been well defined...

BACKGROUND: Fetal-type posterior cerebral arteries (F-PCAs) might result in alterations in hemodynamic flow patterns and may predispose an individual to an increased risk of posterior communicating artery aneurysms (PCoAAs). OBJECTIVE: To determine the association between PCoAAs and the presence of ipsilateral F-PCAs. METHODS: We retrospectively reviewed the radiographic findings from 185 patients harboring 199 PCoAAs that were treated at our institution between 2005 and 2015...

Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017...

Endovascular treatment of intracranial aneurysms using flow-diverting devices has revolutionized the treatment of large and complex lesions due to its minimally invasive nature and potential clinical outcomes. However, incomplete or delayed occlusion and persistent intracranial aneurysm growth are still an issue for up to one-third of the patients. We evaluated two patients with intracranial aneurysm located at the internal carotid artery who were treated with flow-diverting devices and had opposite outcomes...

Feng Xu, Nicholas C Bambakidis
In anterosuperior-projecting anterior communicating artery (ACoA) aneurysms, the aneurysm dome usually adheres to one or both proximal A2 segment, which may present technical difficulties. This video demonstrates microsurgical clipping of a ruptured anterosuperior-projecting AComA aneurysm. A 52-year-old male presented with a Hunt-Hess grade II subarachnoid hemorrhage (SAH). Computed tomography showed SAH in the basal cisterns, sylvian and interhemispheric fissures. Angiography demonstrated a wide-necked AComA aneurysm projecting anterosuperiorly...

OBJECTIVE: Frailty, a clinical syndrome associated with loss of metabolic reserves, is prevalent among patients who present to vascular surgery clinics for evaluation. The Clinical Frailty Scale (CFS) is a rapid assessment method shown to be highly specific for identifying frail patients. In this study, we sought to evaluate whether the preoperative CFS score could be used to predict loss of independence after major vascular procedures. METHODS: We identified all patients living independently at home who were prospectively assessed using the CFS before undergoing an elective major vascular surgery procedure (admitted for >24 hours) at an academic medical center between December 2015 and December 2017...

Dorsal internal carotid artery (ICA) aneurysms are notorious for their high morbidity and mortality. They have an extremely fragile wall and have a high chance of rupture and clip slippage during the intraoperative and postoperative period. Strategies proposed to mitigate these problems encompass including part of the normal ICA wall in addition to neck of aneurysm in clip blades, as well as the use of encircling materials (silicon, cellulose, Weck's clip) over a clip. The Achilles' heel of the problem is to take an appropriate thickness of the normal ICA in clip blades...

Introduction Ophthalmic segment aneurysms may present with visual symptoms due to direct compression of the optic nerve. Treatment of these aneurysms with the Pipeline embolization device (PED) often results in visual improvement. Flow diversion, however, has also been associated with occlusion of the ophthalmic artery and visual deficits in a small subset of cases. Case report A 49-year-old Caucasian female presented with subarachnoid hemorrhage due to a ruptured anterior communicating artery aneurysm. On follow-up imaging, the patient was found to have a right asymptomatic ophthalmic segment aneurysm...

Over the past 50 years, the Journal of Neuroscience Nursing (JNN) has grown from a neurosurgical focus to the broader neuroscience focus alongside the professional nursing organization that it supports. Stroke care in JNN focused on the surgical treatment and nursing care for cranial treatment of conditions such as cerebral aneurysm, carotid disease, arteriovenous malformation, and artery bypass procedures. As medical science has grown and new medications and treatment modalities have been successfully trialed, JNN has brought to its readership this information about recombinant tissue plasminogen activator, endovascular trials, and new assessment tools such as the National Institute of Health Stroke Scale...

OBJECTIVE Cerebrovascular bypass surgery is a challenging yet important neurosurgical procedure that is performed to restore circulation in the treatment of carotid occlusive diseases, giant/complex aneurysms, and skull base tumors. It requires advanced microsurgical skills and dedicated training in microsurgical techniques. Most available training tools, however, either lack the realism of the actual bypass surgery (e.g., artificial vessel, chicken wing models) or require special facilities and regulations (e...

OBJECTIVE The pathogenesis of cerebral aneurysms in patients with internal carotid artery (ICA) occlusion is hypothesized to be hemodynamic. For the first time, the authors quantify the hemodynamic characteristics associated with aneurysm formation in patients with ICA occlusion. METHODS Records of patients with unilateral ICA stenosis or occlusion ≥ 90% who underwent hemodynamic assessment before treatment using quantitative MR angiography were retrospectively reviewed. The patients were classified into 2 groups based on the presence or absence of aneurysms...
