OBJECTIVES This study sought to report technical details and clinical results of the first series of endovascular recanalization for cervical internal carotid artery (ICA) occlusion. BACKGROUND Cervical ICA occlusion is associated with impaired cerebral perfusion, which may lead to ischemic cerebral symptoms and hemodynamic infarcts. Neither surgical nor endovascular revascularization has bee...

BACKGROUND AND PURPOSE The natural course of symptomatic carotid artery occlusion with hemodynamic impairment is poor. Surgical revascularization may improve the outcome; however, its efficacy has not been established yet. The goal of this study was to characterize the technical and clinical outcomes following endovascular recanalization of the ICA under cerebral circulatory protection. MATER...

BACKGROUND AND PURPOSE Cerebral vasospasm remains a major problem in patients recovering from aneurysmal subarachnoid hemorrhage despite advances in medical, surgical, and endovascular care. Our purpose was to assess the efficacy of intra-arterial nimodipine, a calcium-channel blocker acting mainly on cerebral vessels, in preventing delayed neurologic deficits in patients with symptomatic vasos...

 Abstract Traumatic descending thoracic aorta pseudo aneurysms have been treated traditionally with open surgery in the past, which have had noticeable rates of mortality and morbidity. A safer method of treatment for this disease is made possible with recent progress in endovascular treatment techniques. In this article, we present three cases of Traumatic descending thoracic aorta pseudo aneu...

INTRODUCTION There has been a paradigm shift in the treatment of AAA with the advent of endovascular aneurysm repair (EVAR). Rapid progress and evolution of endovascular technology has brought forth smaller profile devices and closure devices. Total percutaneous endovascular aneurysm repair (pEVAR) involves the usage of suture-mediated closure devices (SMCDs) at vascular access sites to avoid a...

PURPOSE To report our experience with intraoperative complications involving the internal carotid artery (ICA) during trans-sphenoidal surgery and their outcome with reconstructive endovascular management. METHODS A retrospective review was conducted of patients with an ICA injury related to trans-sphenoidal surgery from 2000 to 2012. Demographic data, clinical charts, indications for treatme...

BACKGROUND AND PURPOSE The optimal management of patients with unruptured intracranial aneurysms remains controversial in elderly populations. The aim of this study was to evaluate technical results and clinical outcomes in a single center of consecutive elderly patients with unruptured intracranial aneurysms treated with endovascular embolization. MATERIALS AND METHODS Between May 2003 and F...

The TIPS procedure is an endovascular operation guided by biplane fluoroscopy. The goal is to pass a needle from the hepatic vein through the liver into the portal vein. We are developing a software for real-time, 3D guidance of the procedure. This paper discusses means of automatically defining the needle from biplane fluoroscopic views.
