OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

BACKGROUND: A few options of extracranial donor vessels exist for utilization in intracranial vascular bypass procedures. To our knowledge, the use of an internal thoracic artery for cerebral revascularization has not been studied previously. Hence, this cadaveric feasibility study was performed. METHODS: The internal thoracic artery was dissected in five adult cadaveric specimens. The proximal diameter, distal diameter, and the length of the vessel were measured and recorded...

A 13-year-old boy with a spontaneous vertebrobasilar artery dissecting aneurysm (VADA) in the extracranial artery, which was only 1 mm away from the initial segment of subclavian artery, was successfully treated with a covered-stent to block the artery of the VADA. Our experience indicates that this is a fast, reliable, effective and economical technique, particularly suitable for surgeries in settings with limited resources.

In patients with atherosclerotic stenosis of the extracranial segment of internal carotid artery, surgical intervention is an effective method to prevent cerebral ischemic stroke. However, this surgical procedure may cause vascular brain damage. The aim of the study was to investigate consequential brain ischemia-reperfusion injury by measuring the cerebral specific marker, neuron-specific (NSE), in serum of patients having undergone internal carotid endarterectomy (CEA). The study involved 25 patients that underwent CEA due to internal carotid artery stenosis...

OBJECTIVE For patients with moyamoya disease (MMD), surgical intervention is usually required because of progressive occlusion of the internal carotid artery. The indirect bypass method has been widely accepted as the treatment of choice in pediatric patients. However, in adult patients with MMD, the most effective treatment method remains a matter of debate. Here, the authors compared the clinical outcomes from MMD patients treated with either extracranial-intracranial arterial bypass (EIAB; 43 hemispheres) or modified encephaloduroarteriosynangiosis (mEDAS; 75 hemispheres) to investigate whether mEDAS is an effective surgical method for treating adults with symptomatic MMD...

Patients undergoing cerebral revascularization surgery have a relatively high incidence of wound complications. We report a case of heterotopic epithelialization of the dura presenting as a non-healing scalp wound after an extracranial-intracranial (EC-IC) arterial bypass. The scalp wound was revised twice without healing. During the third revision, epithelial tissue was found growing on the dura and was removed. After the epithelial tissue was removed, the wound healed without further complications. This case illustrates the importance of thoroughly examining a non-healing wound to find the cause...

OBJECTIVE: The epidemiology of asymptomatic Moyamoya disease (MMD) is still unclear, and the best management remains controversial. The aim of this study is to evaluate the prognosis of these patients with different management, conservative follow-up or surgical treatment. METHODS: This prospective cohort study screened a series of 696 consecutive MMD patients from 2009 to 2015. Patients with any episodes of hemorrhage and ischemic stroke or TIA were excluded. Finally, 61 patients who were followed up for at least 12 months were included, with 52 patients underwent surgical treatment and 9 patients underwent conservative follow-up...

BACKGROUND: and Importance: In skull-base tumors involving the cavernous sinus (CS), indications for aggressive resection are sparse and must be carefully examined because of their invasiveness. With careful evaluation, techniques including internal carotid artery (ICA) sacrifice with or without extracranial-intracranial (EC-IC) bypass may still be an option in some cases. In addition, previous surgery with the sacrifice of potential donor vessels requires adjusting the revascularization strategy...

BACKGROUND: Dramatic hemodynamic changes occur upon removal of an arteriovenous malformation of the brain (bAVM) with a number of potentially serious perioperative complications, such as intracranial hemorrhage and venous occlusive hypertensive syndrome. As these complications largely occur in the postoperative inpatient period, a rapid, repeatable noninvasive investigation to serially monitor relevant intracranial hemodynamics may be of benefit. Though, transcranial Doppler (TCD) and transcranial color duplex (TCCD) are techniques used and available to provide hemodynamic measurements postoperatively, the time course of hemodynamic sequences following bAVM resection remains uncertain...

Although short and long-term outcomes of aortic surgeries have been improving over the past decade, the procedure is likely to be asscociated with life-threatening complications such as neurological deficits caused by suboptimal brain protection or heavily diseased aorta. Contemporary strategies for brain protection are deep hypothermic arrest with or without retrograde cerebral perfusion retrograde cerebral perfusion or selective antegrade cerebral perfusion. At the moment, majority of evidences failed to show the superiority of selective antegrade cerebral perfusion to retrograde one...

We report a rare case of subarachnoid hemorrhage(SAH)due to ruptured extracranial aneurysm originating at the caudal loop of the left posterior inferior cerebellar artery(PICA). A 50-year-old woman presented with severe headache and mild consciousness disturbance. Computed tomography(CT)revealed SAH and intraventricular hemorrhage. Vertebral angiography showed an extracranial aneurysm located on the tonsillomedullary segment of the left PICA. During the surgery, no vessel branches were confirmed near the aneurysm, and the aneurysm was successfully clipped through suboccipital craniotomy with C1 laminectomy...

Ashley M Wabnitz, Tanya N Turan
Symptomatic carotid artery disease is a significant cause of ischemic stroke, and these patients are at high risk for recurrent vascular events. Patients with symptoms of stroke or transient ischemic attack attributable to a significantly stenotic vessel (70-99% luminal narrowing) should be treated with intensive medical therapy. Intensive medical therapy is a combination of pharmacologic and lifestyle interventions consistent with best-known practices as follows: initiation of antiplatelet agent or anticoagulation if medically indicated, high potency statin medication, blood pressure control with goal blood pressure of greater than 140/90, Mediterranean-style diet, exercise, and smoking cessation...

Prognosis after extracranial-intracranial (EC-IC) bypass surgery has only been studied for a few years and the benefits of this procedure are still controversial. In this single-center retrospective study, we examined the long-term prognosis of patients who underwent EC-IC bypass surgery. Subjects were patients with symptomatic internal carotid artery or intracranial lesion occlusive disease who underwent EC-IC bypass surgery between 1991 and 2003. Of these, long-term prognosis was examined in 57 patients (39 male, 18 female; mean age, 61...

Extracranial internal carotid artery (ICA) pseudoaneurysms are uncommon in the pediatric population and are usually secondary to direct trauma to the vessel. Treatment options include surgery (ligation), anticoagulation therapy and endovascular treatment. Endovascular covered stents have shown good results in adult populations, resulting in occlusion of the aneurysm and preservation of the artery without significant complications. However, there have been only limited reports in the literature reporting endovascular carotid stent placement in the pediatric population...
