INTRODUCTION: The aim of this review was to assess the evidence supporting an association between asymptomatic carotid stenosis (ACS) with impaired cognitive function due to chronic cerebral hypoperfusion and/or silent cerebral embolization. EVIDENCE ACQUISITION: PubMed/Medline, Embase and the Cochrane databases were searched up to December 1, 2022 to identify studies focusing on the association between ACS and cognitive function, as well as the mechanisms involved...

The type of closure after carotid endarterectomy (CEA), whether with patching primary closure or eversion resulting optimal results, remains somewhat controversial. We conducted a PubMed literature review search comparing CEA with patching versus CEA with primary closure versus eversion CEA over the past four decades with emphasis on randomized controlled trials and systematic/meta-analysis and large single center or multicenter studies. The data showed that routine carotid patching can be recommended over primary closure (level 1 evidence); however, CEA with primary closure can be used for large internal carotid arteries (ICAs)>6 mm...

BACKGROUND: Surgical training and evaluation of medical devices require simulation models. The aim of this study was to assess a 3D-printed model as a training model for peripheral endovascular procedures, including thromboaspiration in acute limb ischemia (ALI). METHODS: The 3D-simulation model was modeled from an aorta and lower limbs CT scan by segmentation of the arterial light. The 3D simulator was printed in multimaterial with photo-polymerizable resins (Polyjet)...

INTRODUCTION: Criteria and optimal timing for carotid artery revascularization have been polarizing subjects for investigators and clinicians dedicated to carotid artery atherosclerotic disease. A topical review was performed with the purpose of 1) providing an overview of the evidence on the definition of index event and on the definition of delay of intervention; 2) summarizing the rationale for the current definition for the optimal timing for carotid intervention, and 3) drawing a sketch for future directions implementing the aspect of timing in daily clinical practice...

BACKGROUND: Evidence surrounding P2Y12 platelet reactivity units (PRU) impact on bleeding outcomes in patients undergoing coronary artery bypass is varied. This study sought to assess whether on-pump CABG procedures result in increased bleeding in patients with high compared to low PRUs. METHODS: This retrospective cohort study compared those with a PRU level ≤237 (low PRU group) to >237 (high PRU group). The primary outcome assessed massive or severe bleeding in accordance with universal definition of perioperative bleeding criteria...

Asymptomatic carotid stenosis has been shown to be associated with progressive neurocognitive decline, but the effects of carotid endarterectomy (CEA) on this are not well defined. Due to the wide heterogeneity of studies and lack of standardization in cognitive function tests and study design, there is mounting scientific evidence to support the notion that CEA is effective in reversing or slowing neurocognitive decline; however, definitive conclusions are difficult to make. Further, while the association between ACS and cognitive decline has been well document, a direct etiological role has not been established...

BACKGROUND: The GORE EXCLUDER Conformable Endoprosthesis with active control (CEXC) was developed to treat challenging aortic neck anatomy. This study investigated the clinical results and changes in endograft (ap)position during follow-up. METHODS: Patients treated with the CEXC between 2018 and 2022 were included in this prospective single-center study. Computed tomography angiography (CTA) follow-up was grouped into three categories: 0 to 6 (FU1), 7 to 18 (FU2), and 19 to 30 (FU3) months...

BACKGROUND: Fenestrated endovascular aortic aneurysm repair (FEVAR) is used in pararenal abdominal aortic aneurysms to achieve a durable proximal seal. This study investigated the mid-term course of the proximal fenestrated stent graft (FSG) sealing zone on the first and latest available post-FEVAR computed tomographic angiography (CTA) scan in a single-center series. METHODS: In 61 elective FEVAR patients, the shortest length of circumferential apposition between the FSG and the aortic wall (shortest apposition length [SAL]) was retrospectively assessed on the first and last available postoperative CTA scans...

BACKGROUND: Literature is scarce on the course of iliac endograft limb apposition after endovascular aortic aneurysm repair (EVAR), which is why this study was conducted. METHODS: A retrospective observational imaging study was performed to measure iliac apposition of endograft limbs on the first post-EVAR computed tomography angiography (CTA) scan and on the latest available follow-up CTA scan. With center lumen line reconstructions and CT-applied dedicated software, the shortest apposition length (SAL) of the endograft limbs was assessed as well as the distance between the end of the fabric and the proximal border of the internal iliac artery or the endograft-internal artery distance (EID)...

BACKGROUND: The Misago iliac stent has not been compared with other stents. This study aimed to evaluate the 2-year clinical outcomes between the Misago stent and other self-expandable nitinol stents for symptomatic chronic aortoiliac disease. METHODS: This retrospective, single-center observational study enrolled 138 patients (180 limbs; Rutherford classification, between categories 2 and 6) treated with a Misago stent (N.=41) or self-expandable nitinol stent (N...

Atherectomy as an endovascular modality to treat peripheral arterial disease has gained traction over the past 10 years. Unlike most other available technologies, atherectomy works by physically debulking atherosclerotic plaque via a variety of mechanisms being the femoropopliteal segment the most targeted one. The aims of this review were to detail the types of atherectomy available, existing evidence available for atherectomy use in the femoropopliteal segment as compared to other interventions, critical appraisal of its current use and the possible influences on its indication...

Acute limb ischemia (ALI) is an emergency situation requiring rapid diagnosis and treatment. Although the traditional treating strategy for ALI includes open surgery, novel endovascular techniques have been introduced during the last decade. Additionally, many new cases of ALI have been reported due to infection by the SARS-CoV-2 virus. The aim of this study was to present an updated overview of characteristics, diagnosis, and current treating strategies of patients with ALI.

INTRODUCTION: The aim of this study was to perform a systematic review about the clinical and technical aspects of late open conversion for failed endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAA), and to investigate if the need for suprarenal aortic cross clamping, graft infection, urgent procedures, endoleaks and aortic rupture were associated with an increase of 30-days (perioperative) mortality. EVIDENCE ACQUISITION: A literature search was conducted on PubMed using the words "open conversion endovascular" on December 29th , 2021...

BACKGROUND: Ventricular septal rupture (VSR) is an uncommon but life-threatening complication of acute myocardial infarction. Extra corporeal life support (ECLS) use in the preoperative setting allows hemodynamic stabilization for a delayed surgery. We aimed to assess the role of ECLS in the preoperative period of post infarction VSR surgery. METHODS: We retrospectively analyzed all consecutive patients operated for VSR between January 2007 and August 2019. We assessed baseline characteristics, pre and post-operative clinical status and the use of ECLS in the peri-operative period...

BACKGROUND: Total artificial heart (TAH) implantation is a rarely performed procedure. Contrarily, left ventricular assist device (VAD) implantation is rather common in many centers. As transplantation is quantitatively limited cardiac replacement with artificial hearts is a viable alternative in the treatment of severe biventricular heart failure. An alternative to TAH is the implantation of two VADs in a TAH configuration. We hereby present the first multi-center study on 3-months outcomes of patients treated by cardiectomy and placement of two HeartMate 3s in a TAH configuration...

Aortic arch pathologies are commonly treated by open surgery which is still the gold standard. Patients that are unfit for surgery can be effectively treated mini-invasively with novel endovascular endograft specifically designed for the arch. Endovascular technology has remarkably improved in recent years and is a valid alternative option for the treatment of aortic arch. Available endografts on the market include fenestrated and branched (single, double, or triple). Most endograft designed for the aortic arch are custom-made and production time could be limiting...

Advances in thoracic endovascular aortic repair (TEVAR) are enabling the treatment of increasingly proximal pathology. While the practice of vascular surgery has thus far been mostly limited to TEVAR in zone 2 or more distally, there are emerging devices for zone 1 and zone 0 repair that do not require any further arch debranching compared with a zone 2 repair. Moreover, such devices set forth repair options for patients unable to tolerate the insult of open surgery. One zone 0 device under evaluation is the Terumo Relay® Branch (Terumo, Tokyo, Japan) endovascular graft, which is an off-the-shelf device based on the Relay® Pro platform (Terumo)...

Endovascular aortic arch repair has been widely used in select patients who are considered high risk for open surgical repair and have suitable anatomy. The anatomical challenges of placement of stent-grafts in the ascending aorta are many, including the curved configuration, short landing zone, proximity to the aortic valve and coronary arteries and need to incorporate the supra-aortic trunks. Stent-graft designs with fenestrations and/or directional branches are applicable to patients who have suitable landing zones in the aorta and supra-aortic trunks, adequate access and absence of significant atheromatous debris...
