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...

Sung Jun Park, Joon Bum Kim
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)...

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.

Background: Flow diversion with the Pipeline embolization device (PED) is an effective treatment for giant and wide-neck intracranial aneurysms, but the standard transfemoral approach may not be feasible in patients with Type-3 aortic arches. Case Report: An 84-year-old woman presented with a right internal carotid artery (ICA) giant aneurysm and a Type-3 aortic arch, necessitating a transradial approach for access to the right common carotid artery. A triaxial catheter system made for a stable platform for the deployment of two telescoping PEDs to treat the patient's right ICA giant aneurysm...

BACKGROUND: To assess whether noncontrast-enhanced magnetic resonance imaging (NC-MRI) is an alternative to contrast-enhanced computed tomography angiography (CTA) for aortoiliac measurements before endovascular abdominal aortic aneurysm repair (EVAR). METHODS: This study encompasses 30 patients admitted for elective EVAR (27 men and 3 women). Two expert readers (vascular radiologist and vascular surgeon) reviewed CTA images in consensus and chose the proper endograft for each patient...

Neurofibromatosis type 1 (NF-1) is an autosomal dominant genetic disorder, mainly characterized by skin and peripheral nervous system abnormalities. Uncommonly, NF-1 may be associated with peripheral or supra-aortic trunks artery aneurysms. We report a case of symptomatic multiple occipital artery aneurysms detected in a 53-year-old woman affected by sporadic NF-1. An endovascular approach was performed to exclude aneurysms and to stop laterocervical spontaneous hematoma.

We report on a 54-year-old man who presented with an atypical, proximal, intraoperative endoleak after endovascular aortic repair with an Ovation endograft for a 65-mm-diameter abdominal aortic aneurysm. The endografting was complicated by inadvertent bilateral iliac limb insertion into the right gate without cannulation of the left gate. The endoleak was treated by brachial approach: Through the open left gate, the outflow inferior mesenteric artery was coil embolized and the inflow left gate was closed with an Amplatzer plug...

High-definition fluoroscopic imaging is required to perform endovascular procedures safely and precisely, especially in complex cases, resulting in longer procedures and increased radiation exposure. This is of importance for training institutions as trainees, even with sound instruction in as low as reasonably achievable (ALARA) principles, tend to have high radiation exposures. Recently, there was an upgrade in the imaging system allowing for comparison of radiation exposure to patients and providers. We performed an analysis of consecutive endovascular aneurysm repair (EVAR) and superficial femoral artery (SFA) interventions in the years 2013 to 2014...

Surgical repair of extensive thoracic aortic disease induced by repeated aortic dissection is challenging due to its invasive nature in some cases. We report a rare case of successful endovascular repair of a dissected 3-channelled thoracic aortic aneurysm using the PETTICOAT (provisional extension to induce complete attachment) technique and false-lumen embolization (the candy-plug technique). The PETTICOAT technique improved visceral flow, and the false lumen of the aneurysm was completely thrombosed by the candy-plug technique...

The past two decades have seen an increasing recognition that the delivery of safe surgery with low complication rates and good long-term outcomes is a team endeavour embracing the whole patient care pathway. The key role of the anaesthetist in managing the patient through the surgical process is widely understood and has driven the emergence of perioperative medicine. In parallel with these developments there has been a sea change in the organisation of the care of patients presenting for elective abdominal aortic aneurysm (AAA) repair...

PURPOSE: The growth phases of medically treated abdominal aortic aneurysms (AAA) are frequently associated with an (18)F-fluorodesoxyglucose positron emission tomography (FDG-PET) pattern involving low baseline and subsequent higher FDG uptake. However, the FDG-PET patterns associated with the endovascular aneurysm repair (EVAR) of larger AAA are presently unknown. This study aimed to investigate the relationship between serial AAA FDG uptake measurements, obtained before EVAR and 1 and 6 months post-intervention and subsequent sac shrinkage at 6 months, a well-recognized indicator of successful repair...

The progression of thoracic aortic aneurysm depends on regulation of aortic wall homeostasis and on changes in the structural components of the extracellular matrix, which are affected by multiple molecular signalling pathways. We decided to correlate the diameter of ascending thoracic aneurysm with gene expression of inflammation markers (IL-6, CRP), cytokine receptors (IL-6R, TNFR1, and TNFR2), and extracellular matrix components (Emilin-1, MMP9, and TIMP) for detection of the degree of pathological process of TAA formation...

Decorin (DCN) is a small-leucine rich proteoglycan that mediates collagen fibrillogenesis, organization, and tensile strength. Adventitial DCN is reduced in abdominal aortic aneurysm (AAA) resulting in vessel wall instability thereby predisposing the vessel to rupture. Recombinant DCN fusion protein CAR-DCN was engineered with an extended C-terminus comprised of CAR homing peptide that recognizes inflamed blood vessels and penetrates deep into the vessel wall. In the present study, the role of systemically-administered CAR-DCN in AAA progression and rupture was assessed in a murine model...

OBJECTIVES: Loss of muscle mass has been associated with poor survival in several surgical patient populations, including those with an abdominal aortic aneurysm (AAA). We wanted to replicate these findings and assesse the association between psoas muscle area (PMA) and survival in patients with an asymptomatic AAA. METHODS: Patients with an asymptomatic infrarenal AAA who underwent computed tomography (CT) scanning between January 1, 2007, and December 31, 2013, were included in this single-centre retrospective cohort study...

BACKGROUND: Although reducing the incidence of unplanned readmission after thoracoabdominal aortic aneurysm (TAAA) repair represents an important opportunity to improve outcomes, predictors of readmissions are not known. We sought to characterize and identify factors associated with unplanned readmission after discharge in survivors of open TAAA repair. METHODS: Through prospective phone contact and retrospective record review, we determined the frequency and characteristics of unplanned readmissions within 30 days of discharge in 363 patients who were discharged after open TAAA repair...

BACKGROUND: Open surgical repair remains the "gold standard" treatment for chronic type B aortic dissection (cTBD) with aneurysm. Thoracic endovascular aortic repair (TEVAR) has gained popularity in recent years for the treatment of thoracic aortic diseases, including cTBD. We assessed the effectiveness of TEVAR in the treatment of cTBD using the Vascular Quality Initiative (VQI) database. METHODS: The VQI registry identified 4713 patients treated with TEVAR from July 2010 to November 2015, including 125 repairs for cTBD...
