BACKGROUND: With widespread utilization of noninvasive imaging, small enraptured anterior communicating artery (AcoA) aneurysms are increasingly detected in the general population, particularly in elderly patients. We investigated the association between age and clinical characteristics and outcomes of patients with unruptured AcoA aneurysms. METHODS: Between January 2008 and May 2016, information on 179 consecutive patients with unruptured AcoA aneurysms was obtained and included demographic data, aneurysm features, risk factors for formation and rupture, treatment type, complications, and follow-up information...

Hepatic aneurysms are rare, but can prove fatal once they rupture. Transcatheter arterial embolization (TAE) is performed as a prophylactic treatment. The position of the aneurysm determines the degree of difficulty of TAE. Maintaining blood flow to the liver can become difficult, particularly when the aneurysm is at an arterial junction. The patient was a 72-year-old man diagnosed with a hepatic aneurysm. The aneurysm was situated on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries...

BACKGROUND: Despite recent advances in the medical and surgical fields, complications such as infection, pneumonia, or brain swelling may occur after a craniotomy. In some patients, perioperative antibiotic prophylaxis causes adverse effects such as itching, rash, or digestive conditions. Certain patients still develop infections severe enough to require a repeat operation despite antibiotic prophylaxis. Acupuncture has been used to treat inflammatory conditions, and many basic and clinical studies have provided evidence of its anti-inflammatory and immune regulatory effects...

OBJECTIVE The most frequent procedural complication of the endovascular treatment of intracranial aneurysms is a thromboembolic event (TEE); in a subset of patients, such events will cause permanent neurological disability. In patients with unruptured aneurysms, increasing evidence supports the use of periprocedural antiplatelet therapy to prevent TEEs. The object of this study was to evaluate whether patients with ruptured aneurysms and subarachnoid hemorrhage would also benefit from periprocedural antiplatelet therapy...

OBJECTIVE The mechanism by which greater institutional case volume translates into improved outcomes after surgical clipping of unruptured intracranial aneurysms (UIAs) is not well established. The authors thus aimed to assess the effect of case volume on the rate of various types of complications after clipping of UIAs. METHODS Using information on the outcomes of inpatient admissions for surgical clipping of UIAs collected within a national database, the relationship of institutional case volume to the incidence of different types of complications after clipping was investigated...

OBJECTIVE Advanced age is known to be associated with a poor prognosis after surgical clipping of unruptured intracranial aneurysms (UIAs). Keyhole clipping techniques have been introduced for less invasive treatment of UIAs. In this study, the authors compared the complications and clinical and radiological outcomes after keyhole clipping between nonfrail elderly patients (≥ 70 years) and nonelderly patients. METHODS Keyhole clipping (either supraorbital or pterional) was performed to treat 260 cases of relatively small (≤ 10 mm) anterior circulation UIAs...

INTRODUCTION: Unruptured intracranial aneurysms (UIA) have become an issue of greater significance as their detection rates have increased over the years. We present the overall experience of microsurgical clipping of unruptured aneurysms by a single surgeon over a period of more than 16 years. METHODS: The clinical and radiological data were retrospectively reviewed. Clinical outcome at follow-up was assessed by Glasgow Outcome Scale (GOS), and angiograms were reviewed for the degree of occlusion...

PURPOSE: For early detections of asymptomatic intracranial aneurysms, computer aided diagnostic (CAD) frameworks of intracranial aneurysms in magnetic resonance angiography (MRA) images were developed with various enhancement filters. However, discrimination between aneurysms and false positive structures, such as bending or branching portions of vessels could still be a challenging task for the enhancement filters. Therefore, we focused on developing an ellipsoid convex enhancement (ECE) filter based CAD framework, which is capable of enhancing aneurysms while reducing the effect on bending and branching portions of vessels, for detection of intracranial aneurysm candidate...

BACKGROUND: Despite a number of studies on the treatment of unruptured intracranial aneurysms (UIA), the optimal method still remains unclear. OBJECTIVES: The aim of the study was to demonstrate that UIA clipping is a safe procedure and can be a good alternative for patients not qualified for endovascular procedures and who have refused conservative management. MATERIAL AND METHODS: Results were gathered from a sample of 104 patients with UIA treated in our facility over a 9-year period starting January 2005...

BACKGROUND: Recent studies have demonstrated certain hemodynamic characteristics featuring the rupture status of cerebral aneurysms using computational fluid dynamics. These studies were conducted based on the comparison of a large number of ruptured and unruptured aneurysms. However, not only aneurysm size and location but also perianeurysm environment such as hemorrhage and intracranial pressure would affect the hemodynamic changes. Therefore, we hypothesize that a case in which ruptured and unruptured cerebral aneurysms simultaneously exist in the same location would be an ideal model to reveal hemodynamic characteristics of the rupture status...

BACKGROUND: In addition to size and location, morphology of intracranial aneurysm has been proposed to predict rupture. This study was undertaken to compare morphological features between ruptured and unruptured aneurysms and identify those associated with higher rupture risk. METHODS: Between 2010 and 2014, 301 patients with SAH and 204 with unruptuted aneurysms were admitted to our hospital. Two investigators reviewed 3-dimensional angiograms of all aneurysms...

INTRODUCTION/PURPOSE: Flow diversion has allowed cerebrovascular neurosurgeons and neurointerventionalists to treat complex, large aneurysms, previously treated with trapping, bypass, and/or parent vessel sacrifice. However, a minority of aneurysms remain that cannot be treated endovascularly, and microsurgical treatment is too dangerous. However, balloon test occlusion (macro and micro), micro WADA testing, ICG, intra-angiography and intra-operative monitoring are all available to clinically test the hypothesis that vessel sacrifice is safe...

OBJECTIVE The durability of embolization of large aneurysms is enhanced by use of the neck-bridging stent. However, it remains unclear what factors contribute to decreased recanalization. The purpose of this study was to demonstrate the contribution of the straightening effect of the parent artery to the durability of stent-assisted coiling for large aneurysms. METHODS Of the 182 aneurysms treated by embolization since the introduction of the neurovascular stent, 82 consecutive unruptured aneurysms with a diameter greater than 7 mm were selected...

BACKGROUND: Flow diversion is now an established technique to treat unruptured intracranial aneurysms not readily amenable to endovascular coil embolization or open microsurgical occlusion. The role of flow-diverting devices in treating ruptured aneurysms is less clear. PURPOSE: To estimate rates of angiographic occlusion and good clinical outcome in patients with ruptured intracranial aneurysms treated with flow-diverting devices. DATA SOURCES: Systematic review of Ovid MEDLINE, PubMed, Cochrane databases, and EMBASE from inception to December 2015 for articles that included ruptured aneurysms treated with flow diversion...

OBJECTIVE: Posterior communicating artery aneurysms (PcomAAs) are the second most common aneurysm, accounting for 25% of all aneurysms and 50% of internal carotid artery aneurysms. It has been estimated that oculomotor nerve palsy (ONP) occurs in up to one-third of patients with posterior communicating artery (PcomA) aneurysms. Recent research showed a better outcome of ONP in patients with PcomAA after surgical clipping when compared to endovascular coiling. We compared the effect of clipping and coiling on recovery of ONP in the management of patients with PcomAAs...

BACKGROUND: and Importance: Microsurgical treatment for vertebral artery aneurysms can be approached through the lateral aspect of the brainstem and cerebellum. Contralateral approach may be selected in case of complex aneurysms with tortuous running, and the intracranial vertebral artery distal to the aneurysm locates in contralateral cerebello-pontine angle. When performing the aneurysm repair, exposing the V3 segment before craniotomy is advantageous. We describe the detailed surgical procedures about contralateral transcondylar fossa approach with bilateral V3 segment exposure for the repair of a complex vertebral artery aneurysm...

BACKGROUND: Two editions of the International Classification of Headache Disorders (ICHD) diagnostic criteria for "Headache attributed to an intracranial endovascular procedure" have been published, in 2004 and 2013.(1,2) Despite studies that have suggested that the former is not very practical, the ICHD-3 beta did not contain major changes. Moreover, so far no consensus exists regarding characteristics of headache after intracranial endovascular procedure. Thus, there is a need for sound suggestions to improve the ICHD-3 beta diagnostic criteria...
