SILENT EMBOLIC INFARCTS ON COMPUTED TOMOGRAPHY BRAIN SCANS AND RISK OF IPSILATERAL HEMISPHERIC EVENTS IN PATIENTS WITH ASYMPTOMATIC INTERNAL CAROTID …

2009

OBJECTIVES: This study tested the hypothesis that silent embolic infarcts on computed tomography (CT) brain scans can predict ipsilateral neurologic hemispheric events and stroke in patients with asymptomatic internal carotid artery stenosis. METHODS: In a prospective multicenter natural history study, 821 patients with asymptomatic carotid stenosis graded with duplex scanning who had CT brain scans were monitored every 6 months for a maximum of 8 years. Duplex scans were reported centrally, and stenosis was expressed as a percentage in relation to the normal distal internal carotid criteria used by the North American Symptomatic Carotid Endarterectomy Trialists. CT brain scans were reporte…

Tissue Sparing Posterior Cervical Indirect Decompression and Fusion in Foraminal Stenosis

2016

Treatment for patients with cervical foraminal stenosis that present with cervical radiculopathy has experienced rapid progress. Cervical spine surgical options have improved through advances in imaging, instrumentation, implant innovations and novel surgical techniques. While historical treatments are largely safe, comorbidities associated with procedures such as ACDF, TDR, and posterior foraminotomy beg the question if these procedures are too much surgery for select patients that could benefit from a tissue sparing approach. This chapter will introduce a novel, less disruptive surgical technique for achieving indirect decompression and fusion utilizing an intervertebral cervical implant.…

Assessment of coronary artery bypass grafts: value of different breath-hold MR imaging techniques.

1999

Our aim was to evaluate the patency of coronary artery bypass grafts and to detect graft stenosis using different breath-hold MR imaging techniques.Twenty-two patients with 59 grafts (14 internal mammary artery grafts and 45 saphenous vein grafts) and 76 distal anastomoses (singular and sequential grafts) were studied using a 1.5-T scanner. A two-dimensional T2-weighted breath-hold half-Fourier acquisition single-shot turbo spin echo (HASTE) sequence and a three-dimensional breath-hold contrast-enhanced MR angiography sequence (fast imaging with steady-state free precession) were performed. For MR angiography, a bolus of 20 ml of gadopentetate dimeglumine was used. Time delay for contrast i…

VATER/VACTERL association: clinical variability and expanding phenotype including laryngeal stenosis.

1992

Vertebral abnormalities and anorectal and tracheoesophageal defects are the main manifestations in the VATER/VACTERL association. Radial defects vary from radial aplasia to thumb duplication. Heart and renal defects are reported with lower frequency. Additional malformations, such as the laryngeal stenosis described in the present patient, may expand the phenotype of the association. The wide spectrum of congenital abnormalities confirms the high clinical variability of VATER/VACTERL association which seems to be due to a disruption of blastogenesis. © 1992 Wiley-Liss, Inc.

The Association of H1N1 Pandemic Influenza with Congenital Anomaly Prevalence in Europe

2015

BACKGROUND: In the context of the European Surveillance of Congenital Anomalies (EUROCAT) surveillance response to the 2009 influenza pandemic, we sought to establish whether there was a detectable increase of congenital anomaly prevalence among pregnancies exposed to influenza seasons in general, and whether any increase was greater during the 2009 pandemic than during other seasons.METHODS: We performed an ecologic time series analysis based on 26,967 pregnancies with nonchromosomal congenital anomaly conceived from January 2007 to March 2011, reported by 15 EUROCAT registries. Analysis was performed for EUROCAT-defined anomaly subgroups, divided by whether there was a prior hypothesis of…

High Rate of Studies with Level 1 and 2 Evidence among the 100 Most Cited Articles in Lumbar Spinal Stenosis.

2021

Abstract Background To date, no study has used bibliometric analysis to review the most influential articles in lumbar spinal stenosis. The objective of this study was to identify and analyze the characteristics and the level of evidence of the 100 most cited articles on lumbar spinal stenosis Methods The Thomson Reuters Web of Science was accessed to find the 100 most cited articles on lumbar spinal stenosis. For each article, we recorded the number and density of citations, authors, country, journals and years, department, level of evidence, type of study, and if it was part of any multicenter studies. Results Until January 2017, the 100 most cited articles accumulated 11,136 citations (a…

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

The primary device-oriented endpoint was defined as a combination of cardiovascular death target vessel myocardial infarction or target lesion revascularisation. The database included a total of 1549 lesions in 1304 patients with a mean age of 62 +/- 11years. There were 90 ostial lesions (5.8%) in 84 patients (6.4%) located at the ostial RCA (14; 16%) LCX (29; 32%) or LAD (47; 52%). Patients presenting with ostial lesions did not differ from the remaining cohort except for a higher incidence of prior revascularisation. Predilation was performed in 97% of the lesions (vs. 96% in non-ostial p= 0.618) post-dilation in 43% (versus 58% in the non-ostial group p= 0.008). At quantitative coronary angiography treatment of ostial lesions was associated with higher residual stenosis (30% [23-41] vs. 26% [20-37] p= 0.035) but no difference in minimum lumen diameter existed (p= 0.447). Follow-up data were available at 385 [362-465] days. The 12-month Kaplan-Meier estimated rates of scaffold thrombosis were 4.9% and 2.0% (ostial and non-ostial lesion groups respectively log-rank p= 0.005). The device-oriented composite endpoint occurred respectively in 12.6% and 4.6% at 12 months (log-rank p= 0.001). Treatment of ostial lesions was an independent predictor of this endpoint (p= 0.0025 HR 2.65 [1.41-4.97]).OstiumAims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions.
