OBJECTIVE Paraophthalmic aneurysms may exert mass effect on the optic apparatus. Although surgical clipping and endovascular coiling of these aneurysms can be complicated by immediate postoperative visual deterioration, endovascular coil embolization has the unique risk of visual complications later (>24 h) in the perioperative period. METHODS Six(More)
OBJECT The aim of this study was to analyze the endovascular treatment results of using the Onyx liquid embolic system for spinal intramedullary arteriovenous malformations (AVMs). METHODS The clinical and radiological records of 17 patients with symptomatic spinal intramedullary AVMs treated exclusively by embolization with Onyx between 1999 and 2003(More)
This paper proposes a novel computational methodology for modelling the haemodynamic effects of endovascular coil embolization for cerebral aneurysms. We employ high-resolution 3-D angiographic data to reconstruct the intracranial geometry and we model the coiled part of the aneurysm as a porous medium, with porosity decreasing as coils are inserted. The(More)
Selective amygdalohippocampectomy (SelAH) is now widely used in the surgical treatment of patients with medically intractable medial temporal lobe epilepsy (MTLE). We present our single-centre experience of a uniform series of drug-resistant MTLE patients treated exclusively with SelAH. A retrospective study of 50 adult patients (25 males, 25 females, mean(More)
INTRODUCTION Computational fluid dynamics (CFD) is a numerical technique that is used for studying haemodynamic parameters in cerebral aneurysms. As it is now possible to represent an anatomically accurate intracranial aneurysm in a computational model, we have attempted to simulate its endosaccular occlusion with coils and demonstrate the haemodynamic(More)
The coexistence of two histologically different primary tumours in the same brain region is relatively rare. The situation where these tumours in collision appear in an area of a previously excised meningioma is even more rare and only two cases have been reported so far. We present the third case of a 73-year-old woman who underwent an uneventful excision(More)
The successful long-term outcome of microvascular decompression for trigeminal neuralgia is largely dependent on the maintenance of the isolation between the trigeminal nerve and the offending vessel, avoiding also the development of scar tissue around the nerve. We propose an alternative technique to achieve this target by "hanging" the offending vessel(More)
We report our two-year experience in the endovascular treatment of brain aneurysms in relation to their parent artery wall. We prospectively recorded patients with intracranial aneurysms (107 ruptured - 38 unruptured) treated with coiling during a two-year period: 145 patients, 94 females and 51 males - mean age 56 years. The aneurysms were divided into(More)
