BACKGROUND: Ischemic stroke occurs in a significant subset of patients with blunt traumatic cerebrovascular injury (TCVI). The patients are victims of motor vehicle crashes, assaults or other high-energy collisions, and suffer ischemic stroke due to injury to the extracranial carotid or vertebral arteries. SUMMARY: An increasing number of patients with TCVI are being identified, largely because of the expanding use of computed tomography angiography for screening patients with blunt trauma...

BACKGROUND: Not less than 50% of all ischaemic strokes appear to occur resulting from pathology of extracranial arteries. Occlusions and stenoses are more commonly encountered in carotid arteries, with the incidence of occlusion of the internal carotid artery (ICA) ranging from 5 to 10% within the structure of all lesions of brachiocephalic arteries (BCA). AIM: The study was aimed at assessing the results of a surgical procedure of extra-intracranial microanastomosis (EICMA) performed in patients presenting with occlusive and stenotic lesions of BCA at the Neurosurgical Department...

INTRODUCTION: The treatment of giant intracranial aneurysms is one of the most challenging cerebrovascular problems of neurosurgery. We report the rupture of a giant, lobulated, and almost completely thrombosed middle cerebral artery (MCA) aneurysm that is the ninth such report in the literature. We also investigated additional solutions used in the treatment of this patient. CASE PRESENTATION: A 58-year-old man had been admitted with headache 8 years previously (in 2005), and a giant MCA aneurysm was detected...

Cerebral aneurysms are common vascular lesions. Little is known about the pathogenesis of these lesions and the process by which they destabilize and progress to rupture. Treatment decisions are motivated by a desire to prevent rupture and the devastating morbidity and mortality associated with resulting subarachnoid hemorrhage (SAH). For patients presenting with SAH, urgent intervention is required to stabilize the lesion and prevent re-rupture. Those patients fortunate enough to survive a presenting SAH and subsequent securing of their aneurysm must still face a spectrum of secondary sequelae, which can include cerebral vasospasm, delayed ischemia, seizures, cerebral edema, hydrocephalus, and endocrinologic and catecholamine-induced systemic dysfunction in cardiac, pulmonary, and renal systems...

The Hokkaido Medical Society is a group of doctors and medical researchers in Hokkaido. Its purpose is to contribute to medicine and to the improvement of medical treatment. This symposium was carried out in order to inform citizens about the condition known as sudden death. We hypothesize that the incidence of sudden death tends to increase in line with the incidence of metabolic syndrome. Approximately four hundred patients were transported to our hospital by ambulance in a state of cardiopulmonary arrest (CPA) last year...

The management of cerebrovascular disease has advanced considerably in 2015. Five randomized control trials have firmly established the role of endovascular thrombectomy for ischemic strokes due to large vessel occlusion. The randomized trial of intraarterial treatment for acute ischemic stroke (MR CLEAN) (Berkhemer et al. NEJM 2015;372:11-20) was the first of a series on the topic. There was a total of 5 randomized controlled trials published showing benefit in terms of functional outcomes at 90days for mechanical thrombectomy including the Endovascular Therapy for Ischemic stroke with perfusion-imaging selection (EXTEND IA) (Campbell et al...

OBJECTIVE Minimal literature exists on the intraoperative complication rate of pediatric neurosurgical procedures with respect to both surgical and anesthesiological complications. The aim of this study, therefore, was to establish intraoperative complication rates to provide patients and parents with information on which to base their informed consent and to establish a baseline for further targeted improvement of pediatric neurosurgical care. METHODS A clinical complication registration database comprising a consecutive cohort of all pediatric neurosurgical procedures carried out in a general neurosurgical department from January 1, 2004, until July 1, 2012, was analyzed...

The subspecialty of craniofacial surgery emphasizes skeletal exposure, preservation of critical structures, and provision of a superior cosmetic result. In recent decades, an emphasis on minimally invasive neurosurgical exposure has paved the way for increased collaboration between neurosurgeons and craniofacial surgeons.The 1990s saw the growing popularity of an eyebrow incision for orbital roof craniotomies in neurosurgery to address lesions in the anterior skull base. Disadvantages of this approach included conspicuous scarring above the brow skin, risk of injury to the frontal branch of the facial nerve, and numbness from supraorbital or supratrochlear nerve transection...

OBJECTIVE The field of neurosurgery is constantly undergoing improvements and advances, both in technique and technology. Cerebrovascular neurosurgery is no exception, with endovascular treatments changing the treatment paradigm. Clipping of aneurysms is still necessary, however, and advances are still being made to improve patient outcomes within the microsurgical treatment of aneurysms. Surgical rehearsal platforms are surgical simulators that offer the opportunity to rehearse a procedure prior to entering the operative suite...

Surgical revascularization of the brain is one of the most important trends in the development of neurosurgery. Restoration of adequate blood flow through pre- and intracerebral arteries promotes prevention and treatment of ischaemic lesions of the brain in various pathology. The present work was aimed at analysing the experience gained in performing revascularizing operations in patients with cerebral aneurysms at the department of neurosurgery. The authors analysed therapeutic outcomes in a total of 45 patients presenting with giant and complex aneurysms of cerebral arteries and treated from 2009 to 2014...
