Acute aortic injury

INTRODUCTION: The presence of a hypercoagulable state predisposes to venous and arterial thrombi. While the relationship between protein C and S deficiencies with venous thrombus formation is clear, the relationship to arterial thrombi formation is less common. Thromboembolic disease of the renal arteries may result in renal infarction. The development of simultaneous bilateral renal infarction is rare and can lead to significant morbidity and mortality. CASE REPORT: This is a case of a 48-year-old male with known protein C deficiency who presented to the emergency department with sudden onset abdominal pain...

BACKGROUND: This study aims to report the incidence of acute kidney injury following surgical reconstruction after a failed endovascular aneurysm repair (EVAR) in patients with abdominal aortic aneurysms. METHODS: This retrospective study included 44 patients (39 males, 5 females; mean age: 70±11.3 years; range, 35 to 84 years) who underwent emergency or elective surgical reconstruction after failed EVAR between February 2015 and January 2019. Patients were divided into two groups: acute kidney injury group and no acute kidney injury group...

Post-infectious glomerulonephritis (PIGN), an uncommon variety of glomerulonephritis (GN), is characterized by emergence of nephritic syndrome within a few weeks following an infectious event. PIGN typically presents as a mild condition and tends to resolve by the time of diagnosis for GN. Aggregatibacter actinomycetemcomitans belongs to the HACEK group of bacteria, which constitutes less than 3% of bacteria responsible for community-acquired infective endocarditis. We present a case of 29-year-old man suspected of lymphoma with B-symptoms along with severe splenomegaly and nephromegaly...

Background : Postoperative myocardial injury, as detected by an elevated concentration of high-sensitivity cardiac troponin I (hs-cTnI), is a common complication in cardiac surgery that may be linked to mortality. The primary aim of this study was to assess the risk factors associated with increased myocardial injury in patients undergoing minimally invasive mitral valve surgery. Methods : In this retrospective monocentric cohort study, we analyzed all patients who underwent elective minimally invasive mitral valve surgery between January 2019 and December 2022 and were subsequently admitted to our intensive care unit...

BACKGROUND: Dialysis is a rare but serious complication after transcatheter aortic valve replacement. We analyzed the large multicenter TRITAVI (transfusion requirements in transcatheter aortic valve implantation) registry in order to develop and validate a clinical score assessing this risk. METHODS AND RESULTS: A total of 10 071 consecutive patients were enrolled in 19 European centers. Patients were randomly assigned (2:1) to a derivation and validation cohort...

BACKGROUND: This study aimed to examine the preventive effect of amino acids on postoperative acute kidney injury (AKI). METHODS: This was single-center, patient- and assessor-blinded, randomized controlled trial. Patients who underwent aortic surgery with cardiopulmonary bypass were included. The intervention group received 60 g/day of amino acids for up to 3 days. The control group received standard care. The primary outcome was the incidence of AKI...

Contemporary medical practices allow complete percutaneous coronary intervention (PCI) in a considerable number of patients who previously would have been considered too 'high-risk' for such procedures. The use of mechanical circulatory support (MCS) devices during these high-risk PCIs (HR-PCIs) is thought to reduce the potential risk for major adverse events during and after revascularization. The intra-aortic balloon pump (IABP), veno-arterial extracorporeal membrane oxygenation (V-A ECMO), and the Impella are the most common MCS devices in use...

PURPOSE: Acute kidney injury (AKI) is a common early complication secondary to transcatheter aortic valve replacement (TAVR). Studies on the incidence and risk factors for AKI after TAVR surgery are limited to date. Here, we retrospectively analyzed the incidence and risk factors for AKI after TAVR surgery in our hospital. MATERIALS AND METHODS: Patients who underwent TAVR surgery at our hospital from November 2017 to February 2023 were selected. AKI was defined using the 2012 KDIGO definition and staging criteria...

OBJECTIVE: The initial operation for type A aortic dissection has limitations, and there may be a need for reoperation in cases such as giant pseudoaneurysm formation and reduced blood supply to the distal vessels. In this study, we collected case data of patients who underwent cardiac major vascular surgery at our hospital to analyze the effectiveness of reoperation treatment options for type A aortic dissection and to summarize our treatment experience. METHOD: Between June 2018 and December 2022, 62 patients with type A aortic dissection (TAAD) underwent reoperation after previous surgical treatment...

BACKGROUND: Cardiovascular calcification is a pervasive issue throughout chronic kidney disease (CKD) progression. Autophagy, a fundamental cellular process, exerts significant influence on various cardiac pathologies, including arrhythmias, atherosclerosis, heart failure, and notably, valvular, and vascular calcifications. Beclin-1, a crucial eukaryotic protein, plays a major regulatory role in autophagy as part of the phosphatidylinositol-3-kinase (PI3K) complex. Recent evidence suggests a protective role for Beclin-1-mediated autophagy in CKD vascular calcification, raising its potential as a novel therapeutic target in this context...

OBJECTIVE: This study aimed to explore the serum levels of gasdermin D (GSDMD) in uremic (end-stage kidney disease, ESKD) patients and their correlation with vascular calcification (VC) and clinical results. METHODS: This prospective observational cohort study enrolled 213 ESKD patients who were undergoing regular maintenance hemodialysis (MHD) for > 3 months in our hospital from August 2019 to July 2022. The abdominal aortic calcification score (AACS) was used to assess the VC condition of patients with ESKD...

BACKGROUND: This study aims to identify the risk factors contributing to spinal cord injury (SCI) following a type A acute aortic dissection (TA-AAD). METHODS: This retrospective study was conducted at a single center and involved 481 patients who received frozen elephant trunk stent implantation for TA-AAD. Additionally, these patients underwent total arch replacement with deep hypothermic circulatory arrest. This study was performed at Fuwai Hospital between September 2016 and April 2020...

BACKGROUND: Acute type A aortic dissection necessitates rapid and effective arterial cannulation techniques for optimal outcomes. This meta-analysis compares the safety and effectiveness of direct aortic cannulation (AoC) with peripheral cannulation (PC) via the femoral or axillary arteries in aortic surgery for acute type A aortic dissection. METHODS: A systematic review following PRISMA guidelines identified 10 retrospective studies encompassing 2518 patients (961 AoC, 1557 PC)...

INTRODUCTION: Acute aortic occlusion (AAO) is a rare but serious condition associated with significant morbidity and mortality. OBJECTIVE: This review provides an emergency medicine focused evaluation of AAO, including presentation, assessment, and emergency department (ED) management based on current evidence. DISCUSSION: AAO refers to obstruction of blood flow through the aorta due to either thrombosis or embolism. This condition primarily affects older adults ages 60-70 with cardiovascular comorbidities and most commonly presents with signs and symptoms of acute limb ischemia, though the gastrointestinal tract, kidneys, and spinal cord may be affected...

Patients with severe calcific native aortic valve stenosis (AS) who require valve replacement have two options, surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). TAVR was approved in late 2011 for extremely high-risk patients and was subsequently approved for high-risk (2012), intermediate-risk (2016), and low-risk (2019) patients. In 2019, TAVR procedures surpassed SAVR procedures for the first time in the United States. The approach to anesthesia for this procedure has also evolved...

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to control non-compressible hemorrhage not addressed with traditional tourniquets. However, REBOA is associated with acute kidney injury (AKI) and subsequent mortality in severe trauma patients. Herein, we investigated how the degree of aortic occlusion alters AKI in a porcine model. Female Yorkshire-cross swine (n=16, 68.1±0.7Kg) were anesthetized, and had carotid and bilateral femoral arteries accessed for REBOA insertion and distal and proximal blood pressure monitoring...
