Hisashi Kubota, Yasuhiro Sanada, Kazuhiro Nagatsuka, Hiromasa Yoshioka, Michihiro Iwakura, Amami Kato

Date of publication: 03-Jun-2016

Background:Sylvian dissection is an essential microneurosurgical skill for neurosurgeons. The safe and accurate opening of the sylvian fissure is desirable for a good prognosis.

Successful outcome after endovascular thrombolysis for acute ischemic stroke with basis on perfusion-diffusion mismatch after 24 h of symptoms onset

Tobias A. Mattei, Azeem A. Rehman, Carlos R. Goulart, Marília G. Sória, Vanessa Rizelio, Murilo S. Meneses

Date of publication: 03-Jun-2016

Background:Although intravenous thrombolysis is the Food and Drug Administration-approved treatment for acute ischemic stroke (AIS) within 3 h, combined intravenous and intra-arterial thrombolysis with endovascular techniques may be able to extend this traditional time window.

Sacrificing the superior petrosal vein during microvascular decompression. Is it safe? Learning the hard way. Case report and review of literature

Giulio Anichini, Mazhar Iqbal, Nasir Muhammad Rafiq, James W. Ironside, Mahmoud Kamel

Date of publication: 03-Jun-2016

Background:Venous infarction as a complication of microvascular decompression (MVD) is a recognized but extremely rare occurrence in an otherwise standard neurosurgical procedure. Sacrificing one or more veins is considered safe by majority of experienced surgeons and authors. However, in the recent years, there has been growing debate about the management of venous trigeminal compression and/or superior petrosal complex (separation vs. coagulation and cutting of the vein), with few papers describing mild to severe complications related to venous sacrifice.

Onyx removal after embolization of a superior sagittal sinus dural arteriovenous fistula involving scalp artery

Jun Watanabe, Jun Maruya, Keiichi Nishimaki, Yasushi Ito

Date of publication: 03-Jun-2016

Background:Most dural arteriovenous fistula (DAVF) in superior sagittal sinus (SSS) requires multimodal treatment. Onyx embolization is useful for DAVF; however, scalp artery embolization has cast extrusion risk.

Surgical flow modification of the anterior cerebral artery-anterior communicating artery complex in the management of giant aneurysms of internal carotid artery bifurcation: An alternative for a difficult clip reconstruction

Felix Hendrik Pahl, Matheus Fernandes de Oliveira, André Luiz Beer-Furlan, José Marcus Rotta

Date of publication: 03-Jun-2016

Background:Internal carotid artery bifurcation (ICAb) aneurysms account for about 2–15% of all intracranial aneurysms. In giant and complex cases, treatment may be difficult and dangerous, once some aneurysms have wide neck and anterior cerebral artery (ACA) and middle cerebral artery (MCA) may arise from the aneurysm itself. Clip reconstruction may be difficult in such cases. Whenever possible, the occlusion of ACA transform the bifurcation in a single artery reconstruction (ICA to MCA), much easier than a bifurcation reconstruction.

An unusual variant of the callosomarginal artery from the A1 segment of the anterior cerebral artery

Jun Yoshida, Hiroshi Kashimura, Masaru Takeda, Kenta Aso

Date of publication: 03-Jun-2016

Background:Although the anatomy of the A1 segment of the anterior cerebral artery (ACA) is highly variable, a callosomarginal artery (CMA) arising from the A1 segment of the ACA is rare.

A unique case of calvarial hemangioma

Altaf Rehman Kirmani, Arif Hussain Sarmast, Abdul Rashid Bhat

Date of publication: 03-Jun-2016

Background:Calvarial hemangiomas are one of the rarest neoplasms affecting the skull, predominantly occurring in parietal and frontal bones.

Diabetes may affect intracranial aneurysm stabilization in older patients: Analysis based on intraoperative findings

Jihye Song, Yong Sam Shin

Date of publication: 03-Jun-2016

Background:Only a small proportion of aneurysms progress to rupture. Previous studies have focused on predicting the rupture risk of intracranial aneurysms. Atherosclerotic aneurysm wall appears resistant to rupture. The purpose of this study was to evaluate clinical and morphological factors affecting atherosclerosis of an aneurysm and identify the parameters that predict aneurysm stabilization.

Radiotherapy-related intracranial aneurysms: A role for conservative management

Sayal Parag, Zafar Arif, Rajaraman Chittoor

Date of publication: 03-Jun-2016

Background:Radiotherapy-related intracranial aneurysms are a recognized but rare phenomenon and often present following rupture leading to subarachnoid hemorrhage. Treatment poses a particular dilemma and both endovascular, and surgical approaches have been used with varied success. We present the case of a radiotherapy-related aneurysm treated conservatively with a favorable outcome.

Therapeutic hypothermia and ischemic stroke: A literature review

Rizwan A. Tahir, Aqueel H. Pabaney

Date of publication: 03-Jun-2016

Background:Ischemic stroke is the fifth leading cause of death in the US. Clinical techniques aimed at helping to reduce the morbidity associated with stroke have been studied extensively, including therapeutic hypothermia. In this study, the authors review the literature regarding the role of therapeutic hypothermia in ischemic stroke to appreciate the evolution of hypothermia technology over several decades and to critically analyze several early clinical studies to validate its use in ischemic stroke.
