Characterization of the cortical laser-doppler flow and hippocampal degenerative patterns after global cerebral ischaemia in the goat.

1998

Large-animal models offer several advantages in the study of cerebral ischaemia: easier control of physiological variables, easier neuropathological evaluation, etc. In the present study we have taken advantage of the unique cerebrovascular anatomy of the goat to reproduce a model of reversible, incomplete, global cerebral ischaemia in a large-sized animal species, in which the effects of successive manoeuvres to stop and re-start cerebral blood flow can be recorded continuously. Early cortical laser-Doppler flow response (up to 2 h) and delayed neuronal degeneration (7 days) in the hippocampal CA1 subfield have been analysed in goats undergoing 5, 10 or 20 min of transient, global cerebral…

A fatal iatrogenic right vertebral injury after transoral odontoidectomy and posterior cervical stabilization for a type II odontoid fracture.

2014

Abstract The authors present a singular case of an iatrogenic right vertebral artery injury, involving a 67 year-old man, who reported a type II odontoid fracture (Anderson and D'Alonzo Classification) and posterior atlantoaxial dislocation following a road traffic accident. A small injury involving the right vertebral artery occurred as a consequence of transoral odontoidectomy and posterior cervical stabilization. It was caused by bone spicules of spinal origin and their presence was confirmed by the histological section of the right vertebral artery at the level of C1–C2. The case confirms how iatrogenic vertebral artery injuries during cervical spine surgery may be potentially lethal, e…

The Diagnosis and Treatment of Peripheral Arterial Vascular Disease

2016

Background In peripheral arterial occlusive disease (PAOD), arterial stenosis or occlusion impairs perfusion in the territory of the distal portion of the aorta and the iliac and leg arteries. In Germany, the prevalence of PAOD rises with age, reaching 20% among persons over age 70. Methods This guideline was prepared by a collaboration of 22 medical specialty societies and two patient self-help organizations on the basis of pertinent publications that were retrieved by a systematic search in PubMed for articles that appeared from 2008 to April 2014, with a subsequent update to May 2015. Results 294 articles were assessed, including 34 systematic reviews and 98 randomized controlled trials …

Venous and arterial thromboembolic complications in COVID-19 patients admitted to an academic hospital in Milan, Italy

2020

Background Few data are available on the rate and characteristics of thromboembolic complications in hospitalized patients with COVID-19. Methods We studied consecutive symptomatic patients with laboratory-proven COVID-19 admitted to a university hospital in Milan, Italy (13.02.2020–10.04.2020). The primary outcome was any thromboembolic complication, including venous thromboembolism (VTE), ischemic stroke, and acute coronary syndrome (ACS)/myocardial infarction (MI). Secondary outcome was overt disseminated intravascular coagulation (DIC). Results We included 388 patients (median age 66 years, 68% men, 16% requiring intensive care [ICU]). Thromboprophylaxis was used in 100% of ICU patients…

Effects of prostaglandin E1 and buflomedil on left ventricular function in patients with severe chronic occlusive arterial disease: a prospective, ra…

1999

In this study, the effect of a course of prostaglandin E ( 1 ) (60 microg/d intravenously [i.v.]) or buflomedil (150 mg/d i.v.) treatment on parameters of left ventricular systolic function was investigated by echocardiography in patients of comparatively advanced age with severe peripheral occlusive arterial disease (Fontaine's stage III or IV). The study population was 20 patients, 12 men and 8 women, between 51 and 85 years of age (average age, 73. 7 years), with multiple coexisting medical conditions. These patients were no longer suitable candidates for other forms of interventional or surgical treatment. The patients were treated with prostaglandin E ( 1 ) or buflomedil in the dosages…

Randomized controlled comparison of optimal medical therapy with percutaneous recanalization of chronic total occlusion (COMET-CTO)

2021

The aim of this randomized prospective study was to evaluate the quality of life (QoL) using the “Seattle Angina Questionnaire” (SAQ) in patients with chronic total occlusion (CTO) in coronary arteries treated with either percutaneous coronary intervention (PCI) or optimal medical therapy (OMT), or only with OMT. The potential benefits of recanalization of CTO by PCI have been controversial because of the scarcity of randomized controlled trials. A total of 100 patients with CTO were randomized (1:1) prospectively into the PCI CTO or the OMT group (50 patients in each group). There were no baseline differences in the SAQ scores between the groups, except for physical limitation scores (P = …

Obstructive uropathy following aortofemoral graft surgery.

1991

Fifty patients who had undergone aorto-bifemoral bypass with a bifurcated Dacron graft for aortoiliac arteriosclerotic obliteration were examined with real-time sectorial ultrasound to screen for the presence of hydronephrosis. Hydronephrosis was detected in only 1 case. The low incidence of this complication in our cases may be due to the fact that all our patients were explored at least 1 year after surgery. Some may have developed hydronephrosis early, but this may have resolved spontaneously during the first year after the operation, thus remaining undiagnosed. Pathogenic mechanisms suggested for the development of hydronephrosis and therapeutic approaches are discussed. We conclude tha…

Fenestrated Stent Grafting for Short-necked and Juxtarenal Abdominal Aortic Aneurysm

2010

Objectives: To present an 8-year clinical experience in the endovascular treatment of short-necked and juxtarenal abdominal aortic aneurysm (AAA) with fenestrated stent grafts. Methods: At our tertiary referral centre, all patients treated with fenestrated and branched stent grafts have been enrolled in an investigational device protocol database. Patients with short-necked or juxtarenal AAA managed with fenestrated endovascular aneurysm repair (F-EVAR) between November 2001 and April 2009 were retrospectively reviewed. Patients treated at other hospitals under the supervision of the main author were excluded from the study. Patients treated for suprarenal or thoraco-abdominal aneurysms wer…
