Thus, ICG videoangiography may help reduce the incidence of early bypass graft failure. Notre échantillon était constitué de tous les membres de la Société canadienne de neurochirurgie. The, latter was performed by applying the excimer laser–as-. Furthermore, the high, spatial resolution of the technique also allows the sur, team to localize the site of graft occlusion in the case of ear, ly graft failure. The majority of grade 3 to 5 adverse events were deemed unrelated to IORT. . Moyamoya angiopathy (MMA) is a peculiar cerebrovascular condition characterized by progressive steno-occlusion of the terminal part of the internal carotid arteries (ICAs) and their proximal branches, associated with the development of a network of fragile collateral vessels at the base of the brain. direct intraoperative inspection may fail, including its invasiveness, high financial and, novel system in which fluoresecence videoangiography, Recently, intraoperative fluorescence angiography in which indocyanine green (ICG) is used as a tracer has been, Forty patients undergoing cerebral revascularization for hemodynamic cerebral ischemia (11 patients), moya-, Indocyanine green videoangiography provides a reliable and rapid intraoperative assessment of bypass pa-, known allergy to iodine or any adverse reaction to contrast, to 4 minutes. Universitätsklinikum Mannheim. In the last phase, we developed a 3D ICG camera to demonstrate 3D ICG angiographies in real-time. Case 21. Despite the availability of preoperative imaging methods that allow for exquisite and detailed studies of the venous system, neurosurgeons still lack an intraoperative method providing significant data to assess the presence of venous collateral drainage (2, 28).This information is critical to predict the effects of sacrifice of a given vein in a specific patient (). The median OS was 16.2 mo (95% CI: 11.1-21.4) for all patients and 17.8 mo (95% CI: 13.9-21.7) for those receiving PPT. You could not be signed in. Conclusions: FLOW 800 is a useful supplement to ICG-VA for intraoperative cerebral blood flow assessment. The clinical syndrome is a typical one with compression signs of the lateral, extra-formainal nerve root and minimal lumbar pain. ; Teasdale, G.; Timothy, J.; Van Dellen, J.; Westphal, M. 2004-03-25 00:00:00 Acta Neurochir (Wien) (2004) 146: 421-430 DOI 10.1007/s00701-003-0205- Conference Report th 12 . 2008 erhielt er dort die Lehrbefugnis (venia legendi) für das Lehrgebiet Neurochirurgie. for intraoperative assessment of vascular flow.

Magnetic resonance imaging (MRI) revealed an enhanced solid tumor in the medulla oblongata. Chronic subdural haematoma (CSDH) is one of the most common neurological disorders, and is especially prevalent among elderly individuals. The procedure is probably of limited value, if any, in the management of large completed infarcts but may be indicated in selected patients with small infarctions who have preserved most of their cerebral function and who have had evidence of subsequent focal ischemic events. 3, This 19-year-old woman with neurofibromatosis T, presented with a 2-year history of recurrent bihemispheric, ischemic events and focal epileptic seizures.

The preferred surgical method continues to attract debate. Superficial feeders and drainers were identified and flow dynamic changes in the tumor were assessed by intra-arterial ICG videoangiography. Nach Abschluss seines Studiums der Humanmedizin 1998 in Basel wurde Professor Hänggi 2003 Oberarzt an der Neurochirurgischen Klinik des Universitätsklinikums Basel. Decompres­sive Surgery for the Treatment of Malignant Infarction of the Middle Cerebral Artery (DESTINY): a randomized, control­led trial. The direct STA-MCA bypass provided early augmentation of cerebral perfusion, whereas the indirect EDMS provided a more durable long-term revascularization, indicating a complementary association between the two revascularization methods. lateral projection (right ECA injection). Right: Postoperative DS angiogram (lateral projection) of the left ECA demonstrating bypass graft patency.

This assessment compares the findings from 13 surgical series of EC-IC (1,464 patients) with those reported in the only prospective, randomized, cooperative trial of this procedure (1,377 patients). Dresden, The role of this operation in managing common manifestations of cerebral vascular disease such as focal transient cerebral ischemic attacks (TIAs) and amaurosis fugax, although not fully established, appears encouraging. The goal of this study was to assess the consistency of different diagnostic modalities for evaluating intracranial bypass patency. Predictable changes include a trend towards coiling rather than clipping of cerebral aneurysms, an increasing number of .

Antithrombotic agents are usually prescribed in ischemic MMA, although the coexisting hemorrhagic risk should be considered. The STA-MCA bypass and EMS function were graded as Grade I (poor), II (moderate), or III (good) on the basis of the angiograms. cranial arterial bypass to reduce the risk of ischemic stroke. extraintracranial bypass [STA-MCA bypass] plus encephalomyosynangiosis [EMS]) in 10 pediatric and 10 adult patients. Analysis of the outcomes in the 1,464 patients included in the surgical series produced insufficient evidence to support a conclusion that post-EC-IC bypass stroke rates were lower than the rates of either the medically or surgically treated groups in the controlled clinical trial. Imaging studies obtained in a 51-year-old woman with moyamoya disease. Magnetic resonance imaging, and DS angiography revealed a giant, fusiform aneurysm of, the left ICA with compression of the optic chiasm (Fig. Notre échantillon était constitué de tous les membres de la Société canadienne de neurochirurgie. and 10 control patients. The primary outcome was the development of clinical DCI (delayed ischemic neurologic deficit). After ICG-VA, FLOW 800 provides a color-coded map to directly observe the dynamic distribution of blood flow and to calculate semiquantitative blood flow parameters later. 18. FLOW 800 data were correlated with patient characteristics, clinical outcomes, and intraoperative decision-making.

In the absence of reliable, objective evidence of the existence of a group of patients in whom surgical intervention is superior to medical treatment in reducing the frequency of stroke, the results of the single controlled clinical trial, which demonstrated no benefit of bypass, must be accepted as the best evidence currently available. Some improvement in fluorescein circulation and rCBF also was seen in cortex supplied by sclerotic MCA branches. More recently she ex-, perienced recurrent left hemispheric TIAs. „Mit einer in Forschung und Lehre starken Fakultät, zwei für mein Gebiet interessanten Forschungsschwerpunkten – einem vaskulären und einem neurologischen – und ihrer engen Anbindung an die Universität Heidelberg haben wir auch von wissenschaftlicher Seite beste Voraussetzungen, ein überregional erfolgreiches Zentrum für Neurochirurgie zu etablieren.“ Dazu zählt nicht nur der Ausbau der Neurochirurgischen Klinik und die Erweiterung des neurochirurgischen Behandlungsspektrums, sondern auch die interdisziplinäre Vernetzung mit Nachbardisziplinen.

Medical Systems) was injected intravenously as a bolus. ICG-VA and FLOW 800 can help to determine the blood flow status of the parent artery after aneurysm clipping and the bypass vessels after aneurysm bypass surgery. Conclusion: We proposed a method and proved its feasibility for producing a 3D ICG angiography camera to be mounted on the next generation of neurosurgical microscopes. It provides intraoperative information allowing revision to reduce the incidence of technical errors that may lead to early graft thrombosis. Accordingly, moyamoya syndrome was given. Hierbei wurden mittels einer fiberopti-schen Sonde in circa 8 mm Gewebetiefe folgende Parameter bestimmt: Kapillarvenöse Sauerstoffsättigung (SO2); Blutflussgeschwindigkeit (velo) Blutfluss (flow); kapillarvenöser Füllungsdruck (rHb).

To their knowledge, the authors report the first case of a chronic pyogenic abscess of the terminal filum in an adult woman with kyphoscoliosis who presented with lumbar radiculopathies. According to the present study, ICG videoangiography is indicated for the intraoperative, perior over conventional angiographic techniques. The findings of preanastomotic 133Xe clearance studies were variable and a uniform pattern of regional cerebral blood flow (rCBF) changes was not defined.

Noninvasive imaging techniques provide useful data about the patency but their findings should be carefully interpreted due to local anatomical, physiological, and pathological factors. „Die moderne technische Ausstattung und die hervorragend ausgebildeten Kollegen bieten eine ausgesprochen gute Basis, das Behandlungsspektrum um neue Fachgebiete, wie etwa die funktionelle Neurochirurgie, zu erweitern“, erläutert Professor Hänggi das Entwicklungspotenzial seiner Klinik. Background: Foraminal degenerative lumbar stenosis is traditionally considered a result of bony narrowing due to osteophytic appositions on the superior articular process. In no case was there evidence of stenosis or a technical issue at the site of the anastomosis. Over the last years, new evidence has accumulated suggesting that hemodynamic compromise plays a key role in the manifestation of focal ischemic deficits in a subgroup of patients with occlusive cerebrovascular disease. An immediate, substantial (greater than or equal to 15 ml/100 gm/min) increase in rCBF was demonstrated in 73% of patients after anastomosis. Since glucocorticoids have been used for treatment of cSDH in 1962 their role is still discussed controversially in lack of evident data. One potential obstacle to a successful EC–IC bypass, gery is early bypass graft occlusion and concomitant by, pass failure.
