Incidence of endoleak type IA in patients undergoing chimney endovascular aortic repair (ChEVAR) vs. standard endovascular repair.

Objectives: Almost half of endovascular aortic aneurysm repair (EVAR) procedures are performed in hostile anatomy, increasing the risk of procedure related complications such as type IA endoleaks, which may be prevented with the chimney technique in EVAR (ChEVAR). Our aim is to describe the differential characteristics between EVAR in favorable anatomy and ChEVAR in hostile necks.

Materials And Methods: A cohort of patients with infrarenal abdominal aortic aneurysms (AAA) that were treated with EVAR or ChEVAR were included.

Prognostic relevance of female gender on mortality after peripheral artery disease revascularization.

Introduction: Lower limb peripheral artery disease (PAD) presents high morbidity and mortality. Women represent a small subgroup in different studies, with scarce evidence regarding the prognosis of this gender on PAD. The aim of the present work was to determine the prognostic impact of female gender on lower limb PAD revascularization.

[Procedural and long-term outcomes of elective endovascular abdominal aortic aneurysm repair in octogenarians].

Objective: The aim of the study was to compare the immediate and long-term outcomes of endovascular aneurysm repair (EVAR) between patients under and over the age of 80 with abdominal aortic aneurysm (AAA).

Methods: From 2011 to 2017, we conducted a retrospective cohort study with AAA patients who received elective EVAR. Primary outcomes included hospital mortality, length of stay, acute kidney injury, and the need for re-interventions.

[Extracorporeal membrane oxygenation in COVID-19].

Introduction: The role of the use of Extracorporeal Membrane Oxygenation (ECMO) in patients with coronavirus disease (COVID-19) is under discussion. Whereas in patients with Acute Respiratory Distress Syndrome (ARDS) the ECMO is a usual rescue measure used to optimize the oxygenation as a bridge to pulmonary rehabilitation, in patients that have refractory hypoxemic respiratory failure with recovery potential, the use of ECMO could also be beneficial.

Objective: The purpose of this work is to report the first case of COVID-19 that required ECMO in Argentina, with a good response.

Neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio predict in-hospital mortality in symptomatic but unruptured abdominal aortic aneurysm patients.

Background: Symptomatic but unruptured abdominal aortic aneurysm (AAA) is a potentially fatal disease since its etiopathogenesis, involving acute changes in the aortic wall, including inflammation, increasing the probability of impending rupture. The objective of the present study was to assess the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) in patients undergoing urgent symptomatic AAA repair.

Methods: This was a retrospective study including 29 patients with symptomatic AAA repaired between 2011 and 2020.

Novel Common Femoral Artery Lesion Classification in Patients Undergoing Endovascular Revascularization.

Purpose: Common femoral artery (CFA) is a critical segment of the lower-limb arterial tree. We sought to propose an extensive classification in order to appraise a diagnostic and therapeutic approach.

Methods: A retrospective cohort of CFA lesions with endovascular therapy was evaluated.

[Five-year outcomes of elective infrarenal abdominal aortic aneurysm repair at a university hospital in Argentina].

Objective: Few data about outcomes of elective infrarenal abdominal aortic aneurysm (AAA) repair in Latin America have been published. The objective of the present study is to address this aspect in our population.

Method: Retrospective cohort, in which patients with infrarenal AAA undergoing elective surgical or endovascular repair from January 2011 to May 2017 at a university hospital in Autonomous City of Buenos Aires were consecutively included.

Additive prognosis of clinical presentation in revascularized peripheral arterial disease patients.

Background: Peripheral artery disease (PAD) is a frequent cause of morbidity and mortality. It may present with diverse clinical presentations. The aim of this study was to evaluate the prognosis of these clinical presentations.

Common Femoral Artery Stenting: Computed Tomography Angiography Based Long-Term Patency.

Background: Despite considerable morbid-mortality rates, common femoral endarterectomy is still considered the gold standard for atherosclerotic common femoral artery (CFA) disease. The aim of this study was to demonstrate computed tomography angiography based long-term patency after CFA stent placement and to analyze associated risk factors for restenosis.

Methods: A retrospective and observational study was carried out in consecutive patients treated with endovascular stent placement in CFA lesions.

Anterograde and Retrograde Approach With Through-and-Through Wiring Technique to Treat a Ruptured and Extremely Tortuous Giant Popoliteal Artery Aneurism.

Purpose: This technical note aims to show a challenging endovascular treatment approach of a giant and tortuous ruptured popliteal artery aneurism.

Materials And Methods: An 86-year-old male patient was admitted for acute lower right limb ischemia. Angio-MSCT showed highly calcified superficial femoral artery, with a 180° bend in distal portion, followed by a large popliteal aneurism (63 × 61 mm) with a large extent hematoma (142 × 112 × 104 mm).

Prostanoids for critical limb ischaemia.

Background: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects.

Endovascular treatment of paravisceral mycotic aneurysm: Chimmeny endovascular sealing the end of de road.

Open surgery is the elective treatment for mycotic aneurysms of the aorta. This surgery consists of resection of the aneurysm, debridement and revascularization with an in situ or extra-anatomic bypass. Even when surgery has been successful, the morbi-mortality is raised and the endovascular treatment has become an alternative for specific patients.
