Therapeutic approaches Giant Intracranial Aneurysms
This book is published as one of a series entitled Foundations ofNeurological Surgery and is a clearly produced volume. The early sections on laser types and laser physics read easily and are well illustrated, but the one which follows on the interaction oflaser light with neural tissue is a little less clear but quite comprehensive. The section on benign supratentorial tumours is more of a mat...
متن کاملGiant Intracranial Aneurysms at 7T MRI.
Giant intracranial aneurysms are rare vascular pathologies associated with high morbidity and mortality. The purpose of this in vivo study was to assess giant intracranial aneurysms and their wall microstructure by 7T MR imaging, previously only visualized in histopathologic examinations. Seven giant intracranial aneurysms were evaluated, and 2 aneurysms were available for histopathologic exami...
متن کاملSpontaneous thrombosis in giant intracranial aneurysms.
Twelve patients in a series of 22 with giant intracranial aneurysms demonstrated neuroradiological features of partial or total spontaneous intra-aneurysmal thrombosis. The presence of this intra-aneurysmal clot significantly altered the computed tomographic appearance of the giant aneurysm. Massive intra-aneurysmal thrombosis did not protect against subarachnoid haemorrhage and the likelihood ...
متن کاملNMR imaging in the recognition of giant intracranial aneurysms.
Most giant aneurysms present clinically as intracranial mass lesions. Many contain an organized lamellated thrombus with only a small eccentric lumen remaining that can be opacified at angiography. Four patients with such aneurysms were studied using flow-dependent nuclear magnetic resonance scanning sequences. The aneurysms show a smooth rounded margin, and the thrombus within is clearly disti...
متن کاملContrast-enhanced MR angiography of intracranial giant aneurysms.
BACKGROUND AND PURPOSE Intravoxel phase dispersion and flow saturation often prevent adequate depiction of intracranial giant aneurysms on 3D time-of-flight (3D-TOF) MR angiography (MRA). Additional diagnostic difficulties may arise from T1 contamination artifact of an associated blood clot. Our aim was to assess whether contrast-enhanced MRA could improve the evaluation of giant aneurysms and ...
