Endovascular Thrombectomy for Extracranial Internal Carotid Artery Occlusions With Large Ischemic Strokes: Insights From the SELECT2 Trial.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).

Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.

International declaration on rural mental health research: 10 guiding principles and standards.

Rural communities have unique mental health needs and challenges which are often related to the uniqueness of the community itself. On a per-capita basis, the investment in rural mental health research is far less than that in urban communities. Added to this, rural communities are often at risk of researchers, based in large urban universities, visiting, conducting the research with minimal engagement with local stakeholders and limited understanding of the community's social-service-environmental context.

Traumatic posterior sternoclavicular joint dislocation - Current aspects of management.

The posterior sternoclavicular joint dislocation is a rare and potentially life-threatening injury, as massive haemorrhage can occur at the time of trauma, during reduction manoeuvres and drilling. These injuries are rare and a collective experience of managing them is of paramount importance. We present our multidisciplinary experience of managing several of these injuries in our centre, with learning points we have identified.

Components of carotid atherosclerotic plaque in spectral photon-counting CT with histopathologic comparison.

Objectives: This study aimed to demonstrate the effectiveness of spectral photon-counting CT (SPCCT) in quantifying fibrous cap (FC) thickness, FC area, and lipid-rich necrotic core (LRNC) area, in excised carotid atherosclerotic plaques by comparing it with histopathological measurements.

Methods: This is a single-center ex vivo cross-sectional observational study. Excised plaques of 20 patients (71 +/- 6 years; 13 men), obtained from carotid endarterectomy were scanned with SPCCT using standardized acquisition settings (120k Vp/19 μA; 7-18 keV, 18-30 keV, 30-45 keV, 45-75 keV, and 75-118 keV).

Endovascular Therapy for Ischemic Stroke Can Be Successfully Performed by Peripheral Vascular Interventionalists.

Purpose: To describe interventionalist and workflow characteristics of an acute stroke endovascular thrombectomy (EVT) center without a dedicated interventional neuroradiology service and report clinical and radiologic outcomes.

Materials And Methods: Retrospective review was performed of all patients receiving EVT at Christchurch Hospital, New Zealand, from June 2014 to the end of December 2019 from a prospective reperfusion registry. During the study period, 5 peripheral vascular interventional radiologists, 2 of whom had experience in other neuroendovascular procedures, performed 210 EVT procedures.

Endovascular thrombectomy: 31 hours from symptom onset.

Endovascular thrombectomy is an effective intervention for symptomatic intracranial large-vessel occlusion. This treatment has proven benefit up to 24 hours following onset in selected patients with prestroke functional independence. Limited case reports suggest that thrombectomy beyond 24 hours may also be effective.

Operative and 1-Year Outcomes of the Custom-Made Fenestrated Anaconda Aortic Stent Graft-A UK Multicenter Study.

Background: Early and 1-year outcomes are presented for fenestrated endovascular aneurysm repair (FEVAR) of complex aortic aneurysmal disease with the custom-made Anaconda fenestrated stent graft in 101 patients.

Methods: Retrospective site-reported data from the first 101 elective cases (2010-2014) from 4 UK centers were studied to evaluate patient demographics, aneurysm morphology, clinical success, and 1-year outcomes in patients undergoing fenestrated aneurysm repair with the custom-made Anaconda device.

Results: 101 fenestrated grafts (median age 76, 85% male) were implanted with a total of 255 fenestrations (196 renal arteries, 48 superior mesenteric artery, and 11 celiac arteries) with 3% mortality, 98.

First-in-Human Experience With the Gore Balloon-Expandable Covered Endoprosthesis in Iliac Artery Occlusive Disease.

Purpose: To report the first-in-human iliac artery experience of a new balloon-expandable covered endoprosthesis.

Methods: A prospective, single-center pilot study recruited 30 symptomatic patients (mean age 64 years; 18 men) to evaluate the safety and early efficacy of the new Gore balloon-expandable covered endoprosthesis for the treatment of de novo or restenotic common and/or external iliac artery lesions. According to protocol, up to 2 discrete lesions could be treated with a maximum total treated length ≤110 mm.

Vascular closure devices for femoral arterial puncture site haemostasis.

Background: Vascular closure devices (VCDs) are widely used to achieve haemostasis after procedures requiring percutaneous common femoral artery (CFA) puncture. There is no consensus regarding the benefits of VCDs, including potential reduction in procedure time, length of hospital stay or time to patient ambulation. No robust evidence exists that VCDs reduce the incidence of puncture site complications compared with haemostasis achieved through extrinsic (manual or mechanical) compression.

Selective internal radiation therapy for liver malignancies.

Background: Selective internal radiation therapy (SIRT) is a non-ablative technique for the treatment of liver primaries and metastases, with the intention of reducing tumour bulk. This study aimed to determine optimal patient selection, and elucidate its role as a downsizing modality.

Methods: Data were collected retrospectively on patients who underwent SIRT between 2011 and 2014.

Lesbian workers: personal strategies amid changing organisational responses to 'sexual minorities' in UK workplaces.

This article reports emerging findings from a qualitative research study about lesbian, gay and bisexual (LGB) people at work in the UK. The research focuses on the personal experiences and strategies of LGB people amidst changing organisational responses to sexuality within a new legal and political landscape following the introduction of the Employment Equality (Sexual Orientation) Regulations 2003. The article draws specifically on the perceptions of lesbian respondents about a range of issues concerning social inclusion and exclusion in the workplace including coming out at work, treatment by managers and colleagues, workplace and organisational culture and participation in LGBT groups and networks.

Protective effects of beta blockade on pulmonary function when intracranial pressure is elevated.

Intracranial pressure (ICP) was increased by hyperosmolar intracerebral infusion in dogs and the cardiopulmonary and catecholamine (CA) responses followed for 4 h. Increased ICP evoked persistent increases in endogenous CAs, pulmonary vascular pressures, pulmonary blood volume, and venous admixture. Other dogs similarly monitored were treated with a beta-blocking dose of propranolol 25 min after the onset of increased ICP.

Ventilation requirements during high frequency ventilation.

This study was undertaken to investigate ventilatory requirements during high frequency ventilation (HFV). Six anesthetized dogs were ventilated with bird M-2 or Emerson 2-V ventilators at respiratory rates (RRs) ranging from 13-1300 breath/min. PaCO2 was maintained within normal range at all rates by tidal volume (VT) adjustment.

PEEP and CPAP following open-heart surgery in infants and children.

The cardiorespiratory effects of 5 cm H2O end-expiratory pressure were studied in 22 infants and children an hour after open-heart surgery during mechanical ventilation with positive end-expiratory pressure (PEEP) and prior to endotracheal extubation approximately 15 hours later during spontaneous breathing (CPAP). Thermodilution cardiac output determinations and respiratory airflow, volume and pressure recordings were made to assess the effects of airway pressure changes on the respiratory waveform and oxygen delivery. Neither PEEP nor CPAP had a significant effect on cardiac output, intrapulmonary shunting, oxygen consumption, or oxygen utilization.

An assessment of cardiac output by thermodilution in infants and children following cardiac surgery.

A 4 F thermodilution catheter for measuring cardiac output was evaluated for accuracy and linearity in the laboratory and by comparison with the dye dilution method in infants and children following cardiac surgery. When 2 ml of 0 degrees C injectate were used, the correlation of computer determined flows to calibrated pump flows, over a range encountered clinically, was r = 0.998.

Nonivasive assessment by capacitance respirometry of respiration before and after extubation.

Respiration before and after extubation was studied in postoperative patients following weaning from respirator support. Changes in tidal and minute volume and respiratory flow rates were determined by capacitance respirometry, a noninvasive method of monitoring respiration. The presence of an endotracheal tube of 7.
