Fourteen patients with classic tic douloureux were treated with neurovascular decorapression of the trigeminal nerve at its zone of entry into the pons. In addition, selective rhizotomy of the portio major was performed in each patient. This combined procedure gave excellent relief of pain with no recurrences in a 23-month postoperative period. Technical observations and postoperative complicat...

Late-onset epilepsy (LOE) first occurs after 60 years of age and may be due to occult cerebrovascular disease (CVD) which confers an increased risk of stroke. However, patients with late-onset epilepsy are not currently consistently investigated or treated for cerebrovascular risk factors. We discuss how abnormalities of neurovascular unit function, namely, changes in regional cerebral blood fl...

Figure 1. Preoperative right hand: 0.8-cm mass on radiovolar aspect of SF P1, restricted movement in axial direction, freely movable in volar/dorsal direction, negative Tine, nonpulsatile, normal sensation. Because of the location, there was some concern about involvement of the neurovascular bundle. Radiographs were obtained with no foreign visible body.

PURPOSE OF REVIEW The purpose of this review is to provide the latest findings in the constantly changing field of brow and forehead lifting. Significant articles published in the last 24 months are reviewed and discussed based on the personal experience of the senior author (F.P.). RECENT FINDINGS Important anatomical findings have been made over the last few years which will have an impact ...

Introduction The superior gluteal neurovascular bundle passes between the piriformis muscle and gluteus medius muscle as it moves distally to supply the muscles of the gluteal region. The superior gluteal nerve receives spinal contributions from L4, L5, and S1 while the superior gluteal artery is the terminal branch of the posterior division of the internal iliac artery [1]. Multiple variations...

Rupture of an intracranial aneurysm is a serious neuro-vascular event requiring immediate management to avoid devastating neurological sequelae. Despite the rapid evolution of endovascular techniques, clipping is still a necessary tool in aneurysms with non-optimal dometo-neck ratio and in younger patients. Occasionally, optimal positioning of an aneurysm clip with optimal obliteration of the a...

We studied 16 hips (eight cadaver specimens) using arthrography, arthroscopy and anatomical dissection, under incremental traction of up to a maximum of 64 kg, to determine the relationship of the portals to nearby neurovascular structures. The distance of each arthroscopic portal (anterior, anterolateral, and posterolateral) to the associated neurovascular structures was measured after the app...

BACKGROUND AND PURPOSE This study investigated whether a short testing of neurovascular coupling during midterm pregnancy could identify women at risk for subsequent preeclampsia. METHODS Transcranial Doppler sonography of the posterior cerebral artery during a brief visual stimulation was analyzed in 68 women at midterm pregnancy, the primary clinical end point was preeclampsia. RESULTS Wo...

Introduction: Calibrated fMRI is a technique that allows quantitative estimates of the relative changes in cerebral metabolic rate of oxygen (ΔCMRO2) and cerebral blood flow (ΔCBF) that accompany neural activation, thus providing a way to investigate the coupling between neural and vascular activity in the human brain. In this study we consider differences in neurovascular coupling between a yo...

Neurovascular coupling refers to the relationship between neuronal activities and downstream hemodynamic responses. Photoacoustic tomography (PAT), enabling comprehensive label-free imaging of hemodynamic activities with highly scalable penetration and spatial resolution, has great potential in the study of neurovascular coupling. In this review, we first introduce the technical basis of hemody...
