Endovascular Treatment of Abdominal Aortic Aneurysm: Impact of Diabetes on Endoleaks and Reintervention.

Diabetes has a protective effect on abdominal aortic aneurysms (AAAs); however, there are contrasting reports on the impact of diabetes on endovascular aortic repair (EVAR) outcomes, endoleaks (ELs) being the major negative outcome. The present study characterizes ELs and their outcomes in AAA patients, diabetic or not. This single-center, retrospective, comparative study was carried out on 324 AAA patients who underwent elective EVARs between 2007 and 2016 at the University Hospital of Liège (Belgium).

Can Biomarkers and PET Imaging Predict Abdominal Aortic Aneurysm Growth Rate?

Abdominal aortic aneurysm (AAA) is a life-threatening condition due to the risk of aneurysm growth and rupture. Biomarkers linked to AAA pathogenesis are attractive candidates for AAA diagnosis and prognosis. The aim of this study was to assess circulating biomarkers levels relationship with PET imaging positivity and their predictive value in AAA growth rate.

[Right aortic arch with mirror image branching : a rare cause of dysphagia].

We report the case of a 36-year-old female whose dysphagia revealed a congenital anomaly of the thoracic aorta: the right aortic arch with mirror image branching. This is a rare embryonic developmental anomaly where the aorta wraps around the right bronchus and the supra-aortic trunks emerge from the arch in the opposite order to normal. Most of the patients are asymptomatic unless there is a significant compression of mediastinal structures.

Association between PET/CT Scan Findings, Treatment, and Cancer Incidence in a Cohort of AAA Patients.

Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease that poses several challenges. Given the increasing evidence that AAA patients are more likely to develop cancer and the importance of its early detection, we strived to develop a non-invasive tool based on serial FDG-PET/CT scan examinations to identify, among AAA patients, those at risk of cancer. Between 2006 and 2011 we recruited 149 AAA patients, free of cancer at baseline, and followed them until the end of 2021.

[Endoscopic vessel (radial artery and/or vein) : harvesting for coronary bypass grafting].

We report the technique of endoscopic vessel (radial artery and/or vein) harvesting for coronary bypass grafting. Clearly less invasive, this endoscopic approach therefore offers the following advantages for the patient: limited postoperative pain and therefore faster rehabilitation in terms of mobility, less postoperative care, the absence of a long scar and therefore a lower risk of surgical complications with a better aesthetic result, while allowing a quality and a permeability of the graft similar to those obtained after a classic surgical harvest.

Off-Label Use of COR-KNOT Automated Fastener for Manual Bronchial Closure Through a Video-Assisted Thoracoscopic Surgery Approach.

Manual closure of the bronchial stump can be challenging during minimally invasive thoracic surgery. An automated fastener has been used for more than a decade in minimally invasive heart valve surgery to eliminate the need for manual knot tying during the suturing of prosthetic valves. Herein, we describe the use of the COR-KNOT automated fastener (LSI SOLUTIONS, Victor, NY, USA) in a case of video-assisted left upper lobectomy with open section of the bronchus and manual closure with interrupted resorbable sutures for a malignant bronchial tumor located on the proximal part of the left upper lobe bronchus.

[Dysphagia lusoria treated by surgery].

Aberrant right subclavian artery, also called arteria lusoria, is the most common congenital anomaly of the aortic arch (prevalence 0,5-1.8 %). Patients with trisomy 21 have a higher prevalence (35 %).

Serum Acylcarnitines Profile in Critically Ill Survivors According to Illness Severity and ICU Length of Stay: An Observational Study.

The acylcarnitine (AC) profile has been shown to be altered in survivors of a prolonged stay in intensive care unit (ICU), with higher short-chain derivates compared to reference ranges. The present study aimed at describing the AC profile of patients surviving a short ICU stay versus patients surviving a >7-day multiple organ dysfunction. Patients discharged from ICU after an elective and non-complicated cardiac surgery (CS) were recruited.

Alteration of Blood Oxidative Stress Status in Patients with Thoracic Aortic Dissection: A Pilot Study.

Background: Thoracic aortic dissection (TAD) is a life-threatening condition which usually occurs on an aneurysmal aortic wall. Although increasing data have shown that inflammation and oxidative stress play an important role in the patho-physiology of dissection, systemic oxidative stress status (OSS) has not been clearly determined in patients suffering from TAD.

Methods: A cohort of 115 patients presenting type A or B TAD were admitted to our center from 2013 to 2017.

Constrictive pericarditis following cardiac transplantation: a report of two cases and a literature review.

The data on constrictive pericarditis following heart transplantation are scarce. Herein, the authors present 2 patients who developed a constrictive pericarditis 19, and 55 months after heart transplantation. They underwent several diagnostic procedures and successfully recovered after a radical pericardiectomy.

[Aortic valve repair surgery : state of the art and clinical experience of the university hospital center of Liege].

In the past 20 years, there has been a real development of aortic valve repair techniques with an increasing number of publications describing the long-term benefits of aortic valve repair in terms of survival, freedom from major adverse valve related-events and reoperations. Aortic valve repair can now be considered as a valuable alternative to prosthetic valve replacement in patients with dystrophic ascending aorta pathology associated or not to aortic insufficiency with pliable leaflets. In this paper, the authors describe the state of the art of aortic valve repair and present their clinical experience with aortic valve repair surgery in the university hospital center of Liege from April 2021 to September 2022.

Surgery of the ascending aorta via a right anterior minithoracotomy: initial surgical experience of a single center.

Objectives: Full median sternotomy (FMS) is the common surgical access for patients undergoing replacement of the ascending aorta (AA) with or without aortic valve replacement (AVR). The right anterior mini-thoracotomy (RAMT) approach has been increasingly adopted for AVR. This approach has been shown to decrease blood loss and hospital length of stay (LOS) compared with FMS.

Successful heart transplantation from donation after euthanasia with distant procurement using normothermic regional perfusion and cold storage.

While euthanasia has been legalized in a growing number of countries, organ donation after euthanasia is only performed in Belgium, the Netherlands, Spain, and Canada. Moreover, the clinical practice of heart donation after euthanasia has never been reported before. We describe the first case of a heart donated after euthanasia, reconditioned with thoraco-abdominal normothermic regional perfusion, preserved using cold storage while being transported to a neighboring transplant center, and then successfully transplanted following a procurement warm ischemic time of 17 min.

[First report in the Liege province (Belgium) of a concomitant aortic and mitral valve surgery via a minimally invasive right latero-thoracic approach].

Compared to median sternotomy, the potential benefits of minimally invasive single aortic or mitral valve surgery include reduction of blood loss, lower morbidity, and shorter intensive care unit and hospital length of stay. However, there are few reports regarding concomitant aortic and mitral valves minimally invasive surgery via mini-thoracotomy. To the authors knowledge, this is the first report in the Liege area, of a successful minimally invasive right latero-thoracic approach for aortic and mitral valve surgery in a 78-year old woman who presented severe and symptomatic aortic stenosis and mitral insufficiency.

Abdominal Aortic Aneurysm in Heart Transplant Recipients: New Insights from a 30-year Experience at a Single Center.

Background: The improvement in survival rates for heart transplant recipients (HTRs) has increased their risk of developing extracardiac diseases such as abdominal aortic aneurysms (AAAs). The purposes of this study were to evaluate the prevalence and to describe the clinical features and natural history of AAA in HTRs.

Methods: A retrospective review of all patients (375) who underwent heart transplantation (HT) at our center over a 32-year period (1983-2015) was carried out.

Giant vegetation of the tricuspid valve in a healthy patient without risk factors for right-sided endocarditis.

We present the case of a middle-aged man who developed infective endocarditis of the tricuspid valve caused by methicillin-sensitive Staphylococcus aureus and associated with very large vegetation (∼5 cm). Besides the quite unusual size of the vegetation, this report highlights that severe right-sided endocarditis can occur in the absence of classical risk factors (intravenous drug abuse, presence of a cardiac implantable electronic device or other intravascular devices, and underlying right-sided cardiac anomaly) and that some cases of severe tricuspid endocarditis can be successfully treated by partial excision and patch repair.

Unusual localization of vegetations in a native aortic valve infective endocarditis.

In case of valvular infective endocarditis, the infection is mainly localized on the flow side of the valves or at damaged valvular endothelium. We describe a rare case of an aortic valvular ineffective endocarditis with an aortic-valve vegetation situated on the aortic side of the valve. We believe this is the first description of this unusual localization of vegetations in a native aortic valve.

[F] FDG PET/CT can improve the diagnostic accuracy for aortic endograft infection.

Purpose: Aortic endograft infection (EI) can result in potentially life-threatening vascular complications. Unfortunately, it is difficult to obtain a correct diagnosis at an early stage in many patients. This report aims at validating the use of [F] FDG PET/CT imaging for suspected endograft infections in a prospectively collected cohort of patients treated with EVAR and TEVAR.

Heart transplantation in adults with congenital heart disease: a 17-year single center experience.

Background: Heart transplantation (HTx) in adults with congenital heart disease (ACHD) remains challenging because of structural anomalies and often previous procedure. The aim of this retrospective study was to describe the outcomes of heart transplantation (HTx) in a cohort of ACHD patients at our tertiary centre.

Patients And Methods: Between January 1993 and December 2010, 223 consecutive adult patients (age > 18 years) underwent HTx at our institution.

Catamenial pneumothorax, a commonly misdiagnosed thoracic condition: case report.

A 43-year-old woman presented with right-sided chest discomfort associated with dyspnea. The symptoms were related to the menstrual cycle and the patient has already presented several similar episodes. The Chest computed tomography (chest-CT) showed a partial right pneumothorax.

Outcomes and Predictors of Mortality in a Belgian Population of Patients Admitted with Ruptured Abdominal Aortic Aneurysm and Treated by Open Repair in the Contemporary Era.

Background: Abdominal aortic aneurysm (AAA) rupture is a serious condition that results in extremely high mortality rates. Some improvements in outcome have been reported during the last 2 decades. The objective of the present study was to determine the overall and operative (by open repair) mortality related to ruptured AAA in the contemporary era and to identify preoperative, intraoperative, and early postoperative parameters associated with poor outcomes.

[Pulmonary artery percutaneous angioplasty for extrinsic compression induced by squamous cell carcinoma].

Pulmonary artery stenting is usually performed in congenital heart diseases and in cases of extrinsic compression due to a mediastinal tumor or fibrosis. We report one clinical case of a 61-year-old man treated by radiation and chemotherapy for T3N1M0 non-small cell lung carcinoma. He complained of disabling dyspnea.

Ex Vivo Antioxidant Capacities of Fruit and Vegetable Juices. Potential In Vivo Extrapolation.

Background: In support of claims that their products have antioxidant properties, the food industry and dietary supplement manufacturers rely solely on the in vitro determination of the ORAC (oxygen radical antioxidant capacity) value, despite its acknowledged lack of any in vivo relevance. It thus appears necessary to use tests exploiting biological materials (blood, white blood cells) capable of producing physiological free radicals, in order to evaluate more adequately the antioxidant capacities of foods such as fruit and vegetable juices.

Materials: Two approaches to assessing the antioxidant capacities of 21 commercial fruit and vegetable juices were compared: the ORAC assay and the "PMA-whole blood assay," which uses whole blood stimulated by phorbol myristate acetate to produce the superoxide anion.
