Intravascular foreign bodies are a known complication of medical and dental procedures. Dental anesthetic needles may be broken off and retained in the oropharynx. These needles have occasionally been reported to migrate through the oral mucosa in to deeper structures. Here we present the case of a 57-year-old man who had a retained dental needle that had migrated into his internal carotid artery. The needle was removed using endovascular techniques. To our knowledge, this is the first report of a retained dental needle being retrieved using this method...

BACKGROUND: Up to two-thirds of patients are either dependent or dead 3 months after thrombectomy for acute ischemic stroke (AIS). Loss of cerebral autoregulation may render patients with AIS vulnerable to decreases in mean arterial pressure (MAP). OBJECTIVE: To determine whether a fall in MAP during intervention under general anesthesia (GA) affects functional outcome. METHODS: This subgroup analysis included patients from the MR CLEAN trial treated with thrombectomy under GA...

BACKGROUND: Treatment of spinal metastatic lesions by radiofrequency ablation (RFA) before cementation can potentially help in local tumor control and pain relief. This is often limited by access and tumor location. This study reports multicenter clinical and imaging outcomes following targeted RFA (t-RFA) and cement augmentation in neoplastic lesions of the spine. MATERIAL AND METHODS: A retrospective multicenter study of 49 patients with 72 painful vertebral lesions, evaluated for clinical and imaging outcomes following RFA and cement augmentation of spinal metastatic lesions, was undertaken...

PURPOSE: To evaluate temporal trends and factors associated with vertebral augmentation use in myeloma patients with spinal fractures from 2002 to 2012. METHODS: This retrospective cohort study used the Surveillance, Epidemiology and End Results (SEER)-Medicare claims database for 2002 through 2012. We included patients age ≥66 years with myeloma and spinal fractures. First, we evaluated receipt of vertebral augmentation. Second, multivariate logistic regression was used to assess the impact of sociodemographic factors, treatment facility type, and underlying comorbidities on the odds of undergoing vertebral augmentation...

BACKGROUND: The recanalization of cerebral aneurysms after endovascular embolization (coiling or stent-assisted coiling) has been a matter of concern. OBJECTIVE: To systematically evaluate the predisposing factors for cerebral aneurysm recanalization using multidimensional analysis in a large patient cohort. METHODS: In 238 patients with 283 aneurysms, patient baseline characteristics, aneurysm morphological characteristics, treatment-related factors, and changes in flow hemodynamics after endovascular treatment (coiling or stent-assisted coiling) were compared between the recanalization and non-recanalization groups...

BACKGROUND: Most patients with large vessel occlusion (LVO) stroke need to be transferred to receive thrombectomy. To save time, the decision to transfer often relies on clinical scales as a surrogate for LVO rather than imaging. However, clinical scales have been associated with high levels of diagnostic error. The aim of this study is to define the susceptibility to overdiagnosis of our current transfer decision process by measuring the rate of non-treatment transfers, the most common reasons for no treatment and potential predictors...

BACKGROUND AND PURPOSE: During carotid artery stenting (CAS) with the use of closed cell design stents for unstable plaques, tissue prolapse between stent struts was evaluated by optical coherence tomography (OCT). METHODS: 14 carotid stenosis lesions diagnosed as unstable plaques by MRI were evaluated by OCT imaging during CAS using closed cell stents. Cross sectional OCT images within the stented segment were evaluated at 1 mm intervals. The slice rate for the presence of tissue prolapse between the struts was calculated...

INTRODUCTION: Venous outflow obstruction has been implicated in the pathophysiology of a subset of patients with idiopathic intracranial hypertension (IIH), and venous sinus stenting (VSS) has emerged as an effective treatment. However, the effect of anesthesia on venous sinus pressure measurements is unpredictable. A more thorough understanding of the effect of the level of anesthesia on intracranial venous pressures might help to better define patients who might benefit most from stent placement...

BACKGROUND AND PURPOSE: Higher admission serum glucose levels have been associated with poor outcomes in patients with acute ischemic stroke (AIS) treated with IV thrombolysis. We sought to evaluate the association of admission serum glucose with early outcomes of patients with emergent large vessel occlusion (ELVO) treated with mechanical thrombectomy (MT). METHODS: Consecutive AIS patients due to ELVO treated with MT in three tertiary stroke centers were evaluated...

BACKGROUND: The Pipeline Embolization Device (PED) is increasingly used for both on- and off-label purposes for treatment of intracranial aneurysms. The device gradually slows flow of blood into the aneurysm, but the high metal coverage of PED promotes endothelialization of the device. Occasionally, this leads to in-stent stenosis that is clinically well tolerated. We present a multi-institutional Pipeline series that includes three cases of gradual asymptomatic occlusion within the PED and parent vessel...

BACKGROUND: Dural venous sinus thrombosis (DVST) is an increasingly recognized cause of a wide array of neurological symptoms, with outcomes that range from complete recovery to death. The condition of approximately 23% of patients with DVST will worsen after initial presentation, as a result of restricted venous outflow and venous hypertension, but early identification of this subset is challenging. A venous collateral scale (VCS) that grades alternative drainage routes may improve prediction of clinical deterioration...

BACKGROUND: Direct punctures of intracranial tumors have rarely been described in the literature. OBJECTIVE: To assess the feasibility, safety, efficacy, and advantages of using 3D DSA-guided direct puncture rather than the traditional transarterial route to preoperatively devascularize intracranial lesions in particular clinical situations, paying special attention to any correlation with surgical observations; we present the largest series to date. METHODS: Between July 2015 and July 2016, data from all presurgical embolizations performed in our institution were prospectively collected...

BACKGROUND: A neurointerventional examination of intracranial aneurysms often involves the eye lens in the primary beam of radiation. OBJECTIVE: To assess and compare eye-lens doses imparted during interventional and non-interventional imaging techniques for the examination of intracranial aneurysms. METHODS: We performed a phantom study on an anthropomorphic phantom (ATOM dosimetry phantom 702-D; CIRS, Norfolk, Virginia, USA) and assessed eye-lens doses with thermoluminescent dosimeters (TLDs) type 100 (LiF:Mg, Ti) during (1) interventional (depiction of all cerebral arteries with triple 3D-rotational angiography and twice 2-plane DSA anteroposterior and lateral projections) and (2) non-interventional (CT angiography (CTA)) diagnosis of intracranial aneurysms...

Metal-induced encephalopathy after stent-assisted coil embolization is extremely rare. The present report describes two patients who presented with symptomatic intracranial parenchymal edematous lesions after stent-assisted coil embolization. A 64-year-old woman underwent stent-assisted coil embolization for a left internal carotid artery aneurysm; 21 days after the procedure she presented with right hand weakness and MRI revealed multifocal white matter lesions. Another woman aged 52 years underwent stent-assisted coil embolization for right vertebral artery aneurysm; 18 days after the procedure she presented with left-sided sensory disturbance and MRI demonstrated multiple white matter lesions...

A rete mirabile is a vascular network of intercommunicating small arteries or arterioles that replace the definitive adult artery supplying the brain. It supplies the brain in lower mammals but is not seen in normal human embryological development. A 26-year-old man presented with worsening tinnitus that was interfering with his sleep. On CT and digital subtraction angiography he was found to have a temporal lobe pial arteriovenous fistula with bilateral carotid and vertebral rete mirabile. The patient was offered open surgical and endovascular treatment options for pial arteriovenous fistula but he refused both and opted for conservative medical management...
