The fate of spinal arteries after the stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair technique: a case series.

Objective: We evaluated the patency of the spinal arteries (intercostal and lumbar) after the STABILISE (stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair) technique.

Methods: A retrospective analysis of all patients with aortic dissection treated with the STABILISE technique between April 2018 and July 2021 was performed. Imaging analysis of the spinal cord vascular supply was accomplished using multiplanar and maximum intensity projection reconstructed images of pre- and postoperative computed tomography angiograms at 1 month, 12 months, and annually thereafter.

The evolution of management of type B aortic dissection in a series of 100 consecutive cases in a tertiary center.

Introduction And Objectives: Management of aortic dissection is rapidly evolving. The present study aims to assess paradigm shifts in type B aortic dissection (TBAD) treatment modalities and their outcomes according to clinical presentation and type of treatment. We also aim to assess the impact of endovascular technology in TBAD management in order to define organizational strategies to provide an integrated cardiovascular approach.

Herbicides employed in sugarcane plantations have lethal and sublethal effects to larval Boana pardalis (Amphibia, Hylidae).

The increasing demand for biofuels favored the expansion of sugarcane and, as a consequence, in the consumption of pesticides in Brazil. Amphibians are subject to pesticide exposure for occurring in or around sugarcane fields, and for breeding at the onset of the rainy season when pesticide consumption is common. We tested the hypothesis that herbicides used in sugarcane crops, although employed for weed control and manipulated at doses recommended by the manufacturers, can cause lethal and sublethal effects on amphibian larvae.

Is stenting for atherosclerotic renal stenosis an effective technique?

Introduction: One of the treatments for renal artery stenosis is endovascular intervention, but its effectiveness is controversial. The present study aims to analyze the experience of a working group in the endovascular treatment of selected patients with severe obstructive atherosclerotic lesions of the renal arteries, and to characterize early and late results.

Methods: This is a retrospective study of symptomatic patients with atherosclerotic renal artery stenosis who underwent endoluminal therapy between May 12, 1999 and March 12, 2015 at two institutions.

Lethal toxicity of the herbicides acetochlor, ametryn, glyphosate and metribuzin to tropical frog larvae.

Despite the high amphibian biodiversity and increasing pesticide use in tropical countries, knowledge on the sensitivity of tropical amphibians to pesticides remains limited. The aim of this study was to evaluate the acute toxicity of the active ingredients of four of the main herbicides used in Brazilian sugarcane production to tadpoles of two tropical frog species: Physalaemus cuvieri and Hypsiboas pardalis. The calculated 96 h-LC50 (median lethal concentration; in mg a.

Complete Disruption of The Iliac Vessels During Spinal Surgery With Delayed Presentation.

Introduction: The posterior approach to the lumbar spine is most commonly used to treat lumbar spine pathology. Vascular complications, although rare, have a high mortality rate. This is the report of an arterial lesion complicating a L5 hemilaminectomy and its surgical resolution.

Global Impact of Peripheral Obstructive Arterial Disease in Portugal: An Eight Year Study.

Introduction: Peripheral arterial disease has an important impact on morbidity/mortality. The objective of this study was to quantify the impact of this disease in Portugal during the last eight years, expressed by the volume of admissions, treatment strategies and associated morbidity and mortality.

Material And Methods: We collected data from the Diagnosis Related Group national database on primary diagnosis, procedures codes, demographic variables, a number of risk factors, and mortality of all cases admitted from 2009 to 2016 with a primary diagnosis of peripheral arterial disease coded according to the 9th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-9).

[A community-based study of stroke code users in northern Portugal].

Introduction: By 2002 Portugal had one of the highest mortality rates due to cerebrovascular diseases among the European Countries. Meanwhile, several strategies have been adopted to improve prevention and treatment in the acute phase, amongst which the Stroke Code. The purpose of this study is to describe how this measure has been used and its outcome as part of a prospective community based study of stroke/TIA incidence in Northern Portugal.
