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 noninvasive 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)
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)
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 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)
Fragestellung: Mit der Einführung der Mehrzeilendetektor-CT (MDCT) in die klinische Praxis wird eine neue Dimension in der Volumenerfassung und der Orts- und Zeitauflösung in der CT erreicht. Die neuen technischen Möglichkeiten der MDCT erfordern jedoch eine Neudefinition von Untersuchungsstrategien um bestehende CT-Applikationen zu verbessern und neue(More)
Untersucht wurde die Darstellung der normalen und pathologischen Strukturen des Thorax mit der MPR- und MIP-Technik in drei Raumrichtungen berechnet aus einem 1 mm Spiraldatensatz des Mehrzeilen-Spiral-CT. Ein Plexiglasphantom und 20 Patienten wurden im Mehrzeilen-Spiral-CT mit 1 mm Schichtdicke und einem Pitch 6 untersucht. Die mit 0,6 mm Inkrement(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)
PURPOSE To test, whether axial, coronal and sagittal MIP and MPR reconstructions of diagnostic quality can be obtained from 1-mm collimation MSCT data of the chest for the evaluation of thoracic anatomy and pathology. MATERIALS AND METHODS 1-mm collimation MSCT scans were obtained with a pitch of 6 in an acrylic phantom and in 20 patients. Axial images(More)
Fiber tracking allows the in vivo reconstruction of human brain white matter fiber trajectories based on magnetic resonance diffusion tensor imaging (MR-DTI), but its application in the clinical routine is still in its infancy. In this study, we present a new software for fiber tracking, developed on top of a general-purpose DICOM (digital imaging and(More)
