In
these cases, workflow and volumetric BMS202 supplier feedback (WVF) were available at the surgeons’ discretion (Protocol A). In the next 6 cases, WVF was provided only after a complete resection was claimed (Protocol B).
RESULTS: With the novel interactive interface, dynamics of surgical resection, displacement of cortical anatomy, and digitized functional data could be visualized intraoperatively. In the first group (Protocol A), surgeons expressed the view that WVF had affected their decision making and aided resection 0 0 of I I cases). In 3 of 6 cases in the second group (Protocol B), tumor resections were extended after evaluation of WVF By digitizing the cortical surface, an impression of the cortical shift could be acquired in all 17 cases. The maximal cortical shift measured 20 mm, but it typically varied between 0 and 10 mm.
CONCLUSION: Our first clinical results suggest that the embedding of WVF contributes to improvement of surgical awareness and tumor resection in image-guided neurosurgery in a swift and simple manner.”
“OBJECTIVE: Hyperperfusion (HP) is a rare but potentially devastating complication after carotid revascularization. This report describes the clinical I efficacy of staged angio-plasty (SAP) for carotid artery stenosis to prevent HP after carotid revascularization.
METHODS: LY2090314 Eighteen
of 143 patients with high-grade internal carotid artery stenosis scheduled for angioplasty were considered at high risk of postprocedure HP based on their severely impaired cerebral blood flow (CBF) and cerebral vasoreactivity, which were determined using single-photon emission computed tomography with acetazolamide. Nine of the high-risk patients were treated with carotid artery stenting and the other 9 were treated with SAP, which consisted of balloon angioplasty with undersized balloon catheters (Stage 1) followed by carotid artery PDK4 stenting 1 to 2 months later (Stage 2).
RESULTS: In the regular carotid artery stenting group, 5 of 9 patients (56%) showed HP phenomenon on single-photon emission computed tomography just after stenting, and 1 patient (11%) developed
status epilepticus owing to HP. In the SAP group, none of the 8 patients treated by SAP or the 1 patient who required stent placement during the first stage owing to a wall dissection developed postprocedure HP phenomenon or HP syndrome.
CONCLUSION: SAP decreased the HP phenomenon on single-photon emission computed tomography after performing these procedures in selected patients. Although additional intervention is needed, SAP is considered a relatively simple and effective method to avoid HP in patients at high risk of HP after carotid revascularization.”
