INTRODUCTION The quality of surgical treatment of intracranial aneurysms is determined by complete aneurysm occlusion and restoration of flow in the parent, branching and perforating vessels. In postoperative digital subtraction angiography (DSA), unexpected aneurysm residuals and vessel occlusions are frequently detected. Here, the value of two nearly(More)
BACKGROUND In the past 2 decades, intraoperative navigation technology has changed preoperative and intraoperative strategies and methodology tremendously. OBJECTIVE To report our first experiences with a stereoscopic navigation system based on multimodality-derived, patient-specific 3-dimensional (3-D) information displayed on a stereoscopic monitor and(More)
OBJECT The supraorbital approach through an eyebrow incision offers the opportunity to access a wide variety of lesions of the anterior, middle, and even the posterior fossa. The minimally invasive keyhole craniotomy limits brain exploration and retraction and offers the potential for improved surgical outcomes and reduced approach-related complications.(More)
INTRODUCTION Surgical management of multiple intracranial aneurysms may be difficult if located bilaterally. In the case of bilateral middle cerebral artery (MCA) aneurysms, surgical treatment through a unilateral approach is generally not recommended. In this study we describe the surgical technique and important factors that enable treatment of bilateral(More)
OBJECTIVE We have developed a highly interactive virtual environment that enables collaborative examination of stereoscopic three-dimensional (3-D) medical imaging data for planning, discussing, or teaching neurosurgical approaches and strategies. MATERIALS AND METHODS The system consists of an interactive console with which the user manipulates 3-D data(More)
OBJECT The authors report on their experience with a 3D virtual reality system for planning minimally invasive neurosurgical procedures. METHODS Between October 2002 and April 2006, the authors used the Dextroscope (Volume Interactions, Ltd.) to plan neurosurgical procedures in 106 patients, including 100 with intracranial and 6 with spinal lesions. The(More)
OBJECTIVE Improvements in preoperative diagnostic imaging as well as in microsurgical techniques significantly advanced the development of transcranial neurosurgery, allowing the treatment of complicated diseases through smaller and more specific approaches. METHODS In this article, authors overviewed their experience in transcranial endoscope-assisted(More)
BACKGROUND Improvements in preoperative imaging and intraoperative visualization have led to a refinement in surgical techniques. OBJECTIVE Report of a 20-year experience with application of the keyhole technique as a contribution to the ongoing debate on the impact of limited craniotomies in aneurysm surgery. METHODS Over a 20-year period, 1000(More)
OBJECTIVE To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of intracranial aneurysms, using the supraorbital keyhole craniotomy. METHODS The supraorbital keyhole approach was performed through an eyebrow skin incision in 793 cases for treatment of 989 intracranial aneurysms. Of patients, 474(More)
INTRODUCTION Surgery in the temporomesial region is generally performed using a subtemporal, transtemporal, or pterional-transsylvian approach. However, these approaches may lead to approach-related trauma of the temporal lobe and frontotemporal operculum with subsequent postoperative neurological deficits. Iatrogenic traumatisation is especially(More)
