The Prognostic Value of CT Angiography and CT Perfusion in Acute Ischemic Stroke.

BACKGROUND: CT angiography (CTA) and CT perfusion (CTP) are important diagnostic tools in acute ischemic stroke. We investigated the prognostic value of CTA and CTP for clinical outcome and determined whether they have additional prognostic value over patient characteristics and non-contrast CT (NCCT). METHODS: We included 1,374 patients with suspected acute ischemic stroke in the prospective multicenter Dutch acute stroke study. Sixty percent of the cohort was used for deriving the predictors and the remaining 40% for validating them. We calculated the predictive values of CTA and CTP predic

Results of reinterventions for failed endovascular aortic repair: a single-center experience.

AIM: The aim of this paper was to review technical success and clinical outcome of reinterventions to treat complications after endovascular abdominal aortic aneurysm (AAA) repair (EVAR) in a tertiary vascular center. METHODS: The study enrolled 107 patients treated for post-EVAR complications between January 2005 and March 2014. Details of reinterventions, technical success, and midterm clinical outcome were analyzed for reinterventions. Radiologic follow-up after reinterventions was performed by computed tomography scans and duplex ultrasonography. RESULTS: Indications for reinterventions

Hybrid endovascular and open treatment of severe multilevel lower extremity arterial disease.

OBJECTIVE: To evaluate the feasibility and efficacy of simultaneous combined endovascular and open lower extremity arterial reconstruction. DESIGN: Case series study with retrospective analysis of prospectively collected non-randomised data. METHODS: Patients were divided into three groups: group 1 and group 2 included patients who underwent endovascular reconstruction proximal and distal to the site of open reconstruction, respectively, whereas group 3 included patients who underwent open surgery with both proximal and distal endoluminal procedures. Patency analyses were performed using Kap

[Evidence-based guidelines for prevention and therapy of venous thromboembolism].

UNLABELLED: Recently, evidence-based guidelines for the prevention and therapy of venous thromboembolism have been published. Prophylaxis: in General Surgery patients with moderate to severe risk need to be treated with unfractioned (UFH) or low molecular weight (LMWH) heparin. Non pharmacological methods must be reserved to patients with high hemorrhagic risk and in association to heparin to patients with particularly high thromboembolic risk. In high risk Ortopedic Surgery prophylaxis with high doses LMWH or oral anticoagulants (OA) is indicated. Il Neurosurgical Surgery and in politraumatiz

Blood transfusion is associated with increased morbidity and mortality after lower extremity revascularization.

BACKGROUND: Little is known about the significance of blood transfusion in patients with peripheral arterial disease. We queried the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to examine the effect of intraoperative blood transfusion on the morbidity and mortality in patients who underwent lower extremity revascularization. METHODS: We analyzed data from the participant use data file containing vascular surgical cases submitted to the ACS NSQIP in 2005, 2006, and 2007 by 173 hospitals. Current procedural terminology codes were used to selec

Epidural venous plexus enlargements presenting with radiculopathy and back pain in patients with inferior vena cava obstruction or occlusion.

STUDY DESIGN: In the last 2 years, we have examined 9640 patients experiencing back pain or sciatica, using MRI. There were 13 (0.13%) patients who had radicular symptoms that clinically mimicked lumbar disc herniation or spinal stenosis. All of these patients had inferior vena caval obstruction or occlusion that caused engorgement in the epidural and paravertebral venous system, causing nerve root compression. OBJECTIVE: To illustrate the imaging characteristics of 13 patients with epidural engorged veins due to inferior vena cava obstruction or occlusion causing sciatica and low back pain.

[Anticoagulation and antiaggregation in patients with peripheral arterial occlusive diseases].

Peripheral vascular occlusive disease (PAOD) is frequently seen in patients suffering from coronary heart or cerebrovascular disease and is, considered as a prognostic predictor for the morbidity and mortality of this patient group. Thus, secondary antithrombotic and antiplatelet prophylaxis in these patients is not limited to achievement of long-term patency of the revascularized or recanalized arterial segment, but plays as well a pivotal role for the prevention of myocardial infarction and stroke. Generally, claudicants as well as patients undergoing percutaneous transluminal angioplasty (P

Venous thromboembolism in China: epidemiology, management strategies, and future directions.

Venous thromboembolism (VTE) is one of the leading causes of unexpected death among hospitalized patients. It is also a preventable condition, and its incidence can be substantially reduced through active and effective prophylaxis. In recent years, the burden of VTE in China has continued to increase, driven by population aging, a rising prevalence of malignancy, a growing volume of complex surgery, and advances in imaging and laboratory testing. At present, the clinical management paradigm for VTE in China has gradually evolved from the traditional acute event-centered 'diagnosis-treatment' p

Transcranial Doppler sonography for detecting stenosis or occlusion of intracranial arteries in people with acute ischaemic stroke.

BACKGROUND: An occlusion or stenosis of intracranial large arteries can be detected in the acute phase of ischaemic stroke in about 42% of patients. The approved therapies for acute ischaemic stroke are thrombolysis with intravenous recombinant tissue plasminogen activator (rt-PA), and mechanical thrombectomy; both aim to recanalise an occluded intracranial artery. The reference standard for the diagnosis of intracranial stenosis and occlusion is intra-arterial angiography (IA) and, recently, computed tomography angiography (CTA) and magnetic resonance angiography (MRA), or contrast-enhanced M…

< < Уолл-Эйд > > , двусторонняя межядерное офтальмоплегия с конкомитной диплегией: тематический доклад и обзор литературы.

Синдром офтальмоплегии (WEBINO) - это редкое нейро-офтальмологическое заболевание. Его связь с диплегией лиц является еще более редкой, что делает эту комбинацию одним из самых редких синдромов мозга, о чем сообщается лишь в нескольких случаях в литературе. Мы сообщаем о случае 62-летней женщины с множественными факторами сердечно-сосудистого риска и инсультом, обусловленным болезнью малых судов. Она познакомилась с внезапным наступлением диплопии и двусторонним параличом лица. Неврологический анализ показал, что синдром WEBINO связан с диплегией лиц.

Hydrogels-Assisted Cell Engraftment for Repairing the Stroke-Damaged Brain: Chimera or Reality.

The use of advanced biomaterials as a structural and functional support for stem cells-based therapeutic implants has boosted the development of tissue engineering applications in multiple clinical fields. In relation to neurological disorders, we are still far from the clinical reality of restoring normal brain function in neurodegenerative diseases and cerebrovascular disorders. Hydrogel polymers show unique mechanical stiffness properties in the range of living soft tissues such as nervous tissue.
