Abdominal aortic aneurysms (AAA) are localized, commonly-occurring dilations of the aorta. When equilibrium between blood pressure (loading) and wall mechanical resistance is lost, rupture ensues, and patient death follows, if not treated immediately. Experimental and numerical analyses of flow patterns in arteries show direct correlations between wall shear stress and wall mechano-adaptation with the development of zones prone to thrombus formation. For further insights into AAA flow topology/growth interaction, a workout of patient-specific computational flow dynamics (CFD) is proposed to compute finite-time Lyapunov exponents and extract Lagrangian-coherent structures (LCS)...

Importance: Readmissions after surgery lead to poor patient outcomes and increased costs. The Hospital Readmissions Reduction Program (HRRP) penalizes hospitals with excess readmissions after specified medical and surgical discharges. Objective: To evaluate the association of the HRRP with readmissions after major joint surgery (targeted) and procedures with historically high rates not under its purview (nontargeted). Design, Setting, and Participants: In this population-based analysis using a 20% Medicare sample, a retrospective cohort study was performed of patients undergoing one of 5 major surgical procedures between January 1, 2006, and November 30, 2014...

BACKGROUND: Blunt thoracic aortic injury (BTAI) is associated with a high mortality rate and the paradigm of treating patients with BTAI currently favours thoracic endovascular aneurysm repair (TEVAR) if possible. In BTAI, lethal malperfusion caused by a pseudoaneurysm has rarely been reported. We present the first report of a successful case in which a pseudoaneurysm causing the infrequent occurrence of lethal malperfusion and subsequent acute severe ischaemia in the distal portion of the thoracic descending aorta was overcome by veno-arterial extracorporeal membrane oxygenation (VA ECMO) as a bridging therapy until the initiation of TEVAR...

Objective: To compare the value of two 3D imaging reconstruction methods for left atria and pulmonary vein on guiding the catheter ablation for atrial fibrillation (AF). Methods: From January 2014 to January 2017, a total of 100 drug refractory paroxysmal AF patients were divided into left atria direct angiography group (n=50), and indirect angiography group (n=50). 3D CARTO system was applied for mapping and guiding the ablation procedure. Patients assigned to direct angiography group were treated as follows: intraoperative puncture of atrial septum, inject contrast agent directly into the left atrium, conduct left atrial and pulmonary venous rotation angiography, reconstruct three-dimensional image, integrate the image into real-time X-ray system to facilitate circumferential pulmonary vein isolation...

The apolipoprotein E-deficient (apoE-/-) mouse model has advanced our understanding of cardiovascular disease mechanisms and experimental therapeutics. This spontaneous model recapitulates aspects of human atherosclerosis, and allows for the development of dissecting abdominal aortic aneurysms (AAAs) when combined with angiotensin II. We characterized apoE-/- rats and hypothesized that, similar to mice, they would develop dissecting AAAs. We created rats with a 16-bp deletion of the apoE gene using transcription activator-like effector nucleases...

Reconstruction of the visceral and intercostal arteries is the most challenging part in the open repair of thoraco-abdominal aortic aneurysm. For efficient and expeditious reconstruction of these branching vessels, a technique of using a pre-handsewn 8-branch aortic graft (octopod technique) has been adopted. The octopod graft was manually constructed using commercially available two 4-branch aortic grafts that were spatially oriented based on the preoperative computed tomographic images and connected each other prior to surgery...

OBJECTIVES: Axillary artery cannulation is commonly used in thoracic aortic surgery, often utilizing a sidearm graft. Although our institutional preference is femoral cannulation, we use axillary cannulation in select cases with a 'dirty' aorta on computed tomography scan or intraoperative transoesophageal echocardiography. Since 2011, we have routinely used an open Seldinger-guided approach for axillary cannulation. Here, we report our experience with open Seldinger-guided technique, evaluating its safety and efficacy...

The molecular mechanisms underlying thoracic aortic aneurysm (TAA) in patients with bicuspid aortic valve (BAV) are incompletely characterized. MicroRNAs (miRNAs) may play a major role in the different pathogenesis of aortopathy. We sought to employ next-generation sequencing to analyze the entire miRNome in TAA tissue from patients with BAV and tricuspid aortic valve (TAV). In the discovery stage, small RNA sequencing was performed using the Illumina MiSeq platform in 13 TAA tissue samples (seven patients with BAV and six with TAV)...

BACKGROUND: The development, evolution and rupture of intracranial aneurysms is in part related to genetic factors. The role Collagen type I a2 genetic polymorphisms has not been clarified yet. MATERIAL AND METHODS: A meta-analysis was realized by means of a genotype model-fitting processes (allele contrast, recessive, dominant, additive, and co-dominant), and a model-free approach using the generalized odds ratio (ORG). The latter was assessed in association to the degree of dominance (h-index)...

OBJECTIVES: Patients with severe subarachnoid haemorrhage (SAH) often suffer from complications with delayed cerebral ischaemia (DCI) due to vasospasm that is difficult to identify by clinical examination. The purpose of this study was to monitor seizures and to measure cerebrospinal fluid (CSF) concentrations of neurofilament light (NFL) and tau, and to see whether they could be used for predicting preclinical DCI. METHODS: We prospectively studied 19 patients with aneurysmal SAH who underwent treatment with endovascular coiling...

PURPOSE: Endovascular repair of true visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) with stent-grafting (SG) can simultaneously allow aneurysm exclusion and vessel preservation, minimizing the risk of ischemic complications. Our aim was to report a single-center experience on SG of visceral aneurysms, focusing on technical aspects, clinical outcome and mid-term patency. MATERIALS AND METHODS: Consecutive patients affected by VAAs-VAPAs and submitted to endovascular treatment were retrospectively reviewed, and SG cases with the self-expandable peripheral Viabahn stent-graft were analyzed (2003-2017)...

A 71-year-old male with a past medical history of coronary artery bypass surgery developed multiple, infected pseudoaneurysms of the ascending aorta and aortic root 1 year after cardiac catheterization. He underwent aortic root replacement with a 24-mm homograft. Tissue culture from operative specimens revealed invasive Aspergillus fumigatus infection. He was treated with voriconazole for 3 months. After 1 year, he had no recurrence of symptoms, pseudoaneurysm, or fungal infection.
