OBJECTIVES Posterior fossa brain arteriovenous malformations (PFbAVMs) are rare lesions. Management is complicated by eloquence of adjacent neurological structures, multimodality treatment is often necessary, and obliteration is not always possible. We describe a 15-year experience in the management of posterior fossa brain AVMs with a focus on clinical(More)
In patients with cervical spondylotic myelopathy, ventral disease and loss of physiological cervical lordosis are indications for anterior approach. As bone graft and titanium cage present many drawbacks, expandable titanium cage has been recently introduced for this indication. The authors present the clinical and radiological outcomes in patients(More)
OBJECTIVE To evaluate the feasibility of the direct visualization of the distal dural ring (DDR) and adjacent anatomic structures in patients with paraclinoid internal carotid artery aneurysms at 3-T magnetic resonance imaging (MRI). METHODS Six consecutive patients (1 man, 5 women; mean age, 45.5 years; age range, 34-51 years) who underwent a 3-T MRI(More)
BACKGROUND AND PURPOSE Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength limit of the wall tissue. At present, aneurysmal wall mechanics are poorly understood and thus, risk assessment involving mechanical(More)
Anomalous arterial supply of temporal and occipital lobes by anterior choroidal artery: angiographic study. Fig. 4. a Type 3 Takahashi anomaly. A hy-perplastic AChorA supplies the parieto-occipital and calcarine branches, while the PCA proper gives rise to the temporal branches. b Type 4 Takahashi anomaly. The PCA territory is almost completely fed by a(More)
Oesophagus perforation is a possible complication of anterior cervical spine surgery, which generally occurs during the first postoperative days. Delayed perforation is very rare and its management remains controversial. We report the successful management of a delayed oesophagus perforation associated with an osteomyelitis.
OBJECT The purpose of this study was to evaluate the authors' initial experience with the integration of high-resolution rotational and biplanar angiography during neurovascular operative procedures. METHODS Eight patients with intracerebral arteriovenous malformations (AVMs) and aneurysms underwent surgical treatment of their lesions in a combined(More)
OBJECTIVE Neurosurgical management of residual aneurysms (RA) after coiling remains a challenging issue. We present a consecutive series of 21 patients who underwent microsurgical treatment of a previously coiled aneurysm. METHODS We retrospectively reviewed a consecutive series of 21 patients who underwent operations for an RA after coiling between 1997(More)
We describe a patient with a symptomatic left giant carotido-ophthalmic aneurysm who initially underwent coil embolization with subtotal obliteration. The patient’s symptoms were initially stable, but 1 year later, she presented with a rapidly progressive contralateral visual deficit. Although angiogram showed a stable neck remnant, MR confirmed aneurysm(More)
BACKGROUND AND PURPOSE The neuroradiologic location of asymptomatic paraclinoid aneurysms is decisive for patient management. In a preliminary study, we designed a paraclinoid MR protocol (PMP) including high-resolution T2-weighted images in 2 orthogonal planes to define the inferior limit of the distal dural ring plane that represents the borderline(More)
