The Use of Radiomic Analysis in Cardiovascular Diseases.

A The recent years of the cardiovascular medicine saw a rapid development of advanced imaging modalities. The new era of personalized medicine takes advantage of what can be interpreted from medical images, searching for underlying connections between image phenotyping and biological characteristics to support precise clinical decisions. The application of radiomics in cardiovascular imaging has lagged behind other fields, such as oncology.

THE IMPACT OF NEUTROPHIL-TOLYMPHOCYTE RATIO AND PLATELETTO- LYMPHOCYTE RATIO IN CAROTID ARTERY DISEASE.

Introduction: Inflammation is a common underlying feature of atherosclerosis. Several inflammatory biomarkers have been reported to have prognostic value, in several areas, including in vascular surgery. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) may permit to identify patients at greater risk for cerebrovascular events, tailor patient management, improve preoperative status and possibly develop target anti-atherosclerotic therapy.

Management of The Carotid Artery Stenosis in Asymptomatic Patients.

Background: An asymptomatic carotid stenosis (CS) is defined as a stable atherosclerotic luminal narrowing in patients with no history of ipsilateral cerebral or ocular ischemic events in the past six months. The bifurcation of the common carotid artery makes this area vulnerable to atherosclerosis due to the features of haemodynamic flow. The exact prevalence of asymptomatic patients with CS remains unknown and opinions on the treatment of these patients are controversial.

Impact of Gradual Adoption of EVAR in Elective Repair of Abdominal Aortic Aneurysm: A Retrospective Cohort Study from 2009 to 2015.

Introduction: The recommendations about the preferred type of elective repair of abdominal aortic aneurysm (AAA) still divides guidelines committees, even nowadays. The aim is to assess outcomes after AAA repair focusing on differences between endovascular aneurysm repair (EVAR) and open surgical repair (OSR).

Methods: The observational retrospective cohort study of consecutive patients submitted to elective AAA repair at a tertiary center, 2009-2015.

First Population-Based Screening of Abdominal Aortic Aneurysm in Portugal.

Background: The incidence of abdominal aortic aneurysm (AAA) repairs in Portugal is one of the lowest mentioned in the literature. This phenomenon can be justified either by a low prevalence of the disease or by its low detection rate. To date, the prevalence of the pathology is unknown.

Simplified hybrid repair with true lumen recycling for retrograde renovisceral perfusion in a complex chronic aortic dissection.

A 59-year-old man was referred with complicated chronic type B aortic dissection. Despite the false lumen's being dominant in terms of caliber and limb perfusion, visceral arteries originated in a 9-mm true lumen. A staged approach was performed: open aortobi-iliac bypass with preservation of both lumens to the infrarenal aorta, with reinforcement of the aorta and anastomosis with Dacron (wrap technique); exclusion of the dissection by endografting all of the false lumen with three successive thoracic endoprostheses; and maintenance of true lumen perfusion using two periscopes with self-expanding nitinol stents.

True Brachial Artery Aneurysm after Arteriovenous Fistula for Hemodialysis - Case Report.

Introduction: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula.

Endovascular Treatment of Proper Hepatic Artery Aneurysm - Case Report.

Introduction: Hepatic artery aneurysms (HAAs) are rare, representing about 0.1-2% of all arterial aneurysms. They are the second most common splanchnic aneurysms, after splenic artery aneurysms.

Institutional Protocol for Prevention of TEVAR-related Spinal Cord Ischemia - The First 9 Cases.

Introduction: Spinal cord ischemia (SCI) is a feared complication after endovascular correction of thoracic aortic diseases (TEVAR). The guidelines of the European Society for Vascular Surgery recommend prophylactic lumbar drainage (LD) of cerebrospinal fluid in high-risk patients undergoing TEVAR. Our institutional protocol considers as high-risk patients as: coverage of the origin of the Adamkiewicz artery (T9-T12), aortic coverage >15 cm, involvement of collaterals (treated or untreated abdominal aortic aneurysm, left subclavian artery revascularization or bilateral occlusion of the internal iliac arteries) and symptomatic SCI.

Emergency Nightmares - Rupture of Type III Thoracoabdominal Aneurysm.

Unlabelled: Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®).

Outcomes After Catheter Direct Thrombolysis for Acute Limb Ischaemia - Single Center Experience.

Introduction: The aim of this study is to evaluate the outcome of catheter directed thrombolysis (CDT) in acute lower limb ischaemia depending on the underlying etiology.

Methods: Retrospective single center analysis of electronic clinical data on patients with acute lower limb ischaemia treated with CDT. Between January 2011 and September 2017, 128 procedures in 106 patients were included.

Strategies to prevent TEVAR-related spinal cord ischemia.

Spinal cord ischemia remains the Achilles' heel of thoracic and thoracoabdominal diseases management. Great improvements in morbidity and mortality have been obtained with the endovascular approach TEVAR (Thoracic Endovascular Aortic Repair) but this devastating complication continues to severely affect the quality of life, even if the primary success of the procedure - dissection/aneurysm exclusion - has been achieved. Several strategies to deal with this complication have been published in the literature over the time.

Perioperative Drainage of Cerebrospinal Fluid for Endovascular Aortic Surgery.

Introduction: Spinal cord ischemia (SCI) is a feared complication following thoracic endovascular aortic aneurysm repair (TEVAR). European Society for Vascular Surgery guidelines suggest lumbar drainage of cerebrospinal fluid (CSF) in high-risk patients. The institutional protocol proposes as indications for CSF drainage: coverage of Adamkiewicz artery origin (T9-T12), aortic length of coverage >15 cm, compromise of collateral arteries (left subclavian or internal iliac occlusion) and symptomatic SCI.

Quality of life and aortobifemoral bypass: The importance of hypogastric arteries.

Introduction: The aortobifemoral bypass (AFB) is one of the best options to revascularize patients with Aortoiliac Occlusive Disease (AIOD). The impact of this procedure in sexual function (SF) is unpredictable, with 0 to 80% of the patients reporting sexual dysfunction (SD) after surgery. The aim of this study was to evaluate SD after AFB and to assess the importance of patent hypogastric arteries before the procedure.

[TEVAR: a strategy for the diversity of thoracic aorta disease. Series of cases and national prospect].

Objective: To assess endovascular treatment of thoracic aorta diseases in a national centre of angiology and vascular surgery. To quantify the national registry of TEVAR's.

Material And Methods: This unicentric and retrospective study included patients submitted to TEVAR until the end of 2012.

[Pelvic congestion syndrome - A clinical report].

Pelvic congestion syndrome is a common disorder that occurs mainly in young multiparous women. It is characterized by a variable combination of chronic (up to 6 months) not cyclical pain, dyspareunia, dysmenorrhea, urinary symptoms and constipation, that may be associated to perineal and lower limbs varicose veins, with pelvic origin. We report the clinical case of a 26 year-old female, G0P0, with lower limbs varicose veins.
