OBJECTIVE: Endoluminal aortic aneurysm repair is suitable within certain anatomic specifications. This study aims to compare 30-day outcomes of endovascular versus open repairs for juxtarenal and pararenal aortic aneurysms (JAA/PAAs). METHODS: The ACS-NSQIP database was queried from 2012 to 2015 for JAA/PAA repairs. Procedures characterized as emergent were included in the study; however, failed prior repairs and ruptured aneurysms were excluded. The preoperative and perioperative patient characteristics, operative techniques, and outcome variables were compared between the open aortic repair and the endovascular aortic repair groups...

BACKGROUND: Aortic valve insufficiency (AI) at the time of left ventricular assist device (LVAD) insertion needs to be corrected, however there is little known about how to manage bioprosthetic valvular AI. CASE PRESENTATION: A 55-year-old female with dilated cardiomyopathy who previously had a bioprosthetic aortic valve replacement needed a LVAD as a bridge to transplant. Her left ventricular ejection fraction was 10% and had mild to moderate transvalvular AI. She underwent a HeartWare HVAD insertion along with aortic valvular coaptation stitch repair (Park's stitch) to the bioprosthetic valve...

BACKGROUND: Aortic dissection is typically evaluated with computed tomography angiography (CTA). However, the feasibility of using magnetic resonance angiography (MRA) in the ED is unclear. This study examined the indications and outcomes of MRA in suspected aortic dissection evaluation in the ED. METHODS: An IRB approved review identified patients who underwent MRA in the ED for acute thoracic aortic dissection from January 2010 to June 2016. Demographics, clinical assessment, CTA contraindications, outcomes, and ED disposition were analyzed...

PURPOSE: To determine whether statin therapy is associated with abdominal aortic aneurysm (AAA) sac regression after endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: A total of 109 patients treated with EVAR were retrospectively analyzed (no-statin group, n = 45; statin group, n = 64). The primary endpoint was the incidence of AAA sac regression. To investigate independent predictors of AAA sac regression, regression analysis was performed. The mean age was 74 years (range, 55-90 y), and 87...

Clinical presentation of haemoptysis and haematemesis often generates confusion, becoming a difficult task to determine the source of upper airway bleeding. Aortobronchial fistula is a rare entity, but has been a reported complication in patients that have undergone aortic vascular surgery. A high clinical suspicion is fundamental to making this diagnosis. A 69 year old male, with a previous diagnosis of chronic gastritis, is admitted to the emergency room for vomiting blood. In the first 24 hours after admission, the patient develops respiratory insufficiency after an episode of massive bleeding from his mouth...

OBJECTIVE: To evaluate the relationship between the volume of abdominal aortic aneurysm (AAA) procedures undertaken and the primary outcome of mortality in Europe. Previous systematic reviews of this relationship are outdated and are overwhelmingly based on US data. DATA SOURCES: Comprehensive searching within MEDLINE and other bibliographic databases supplemented by citation searching and hand-searching of journals was undertaken to identify studies that reported the effect of hospital or clinician volume on any reported outcomes in adult, European populations, undergoing AAA repair and published in the last 10 years...

OBJECTIVE: Postoperative respiratory adverse events (RAEs) are associated with high rates of morbidity and mortality in general surgery, however, little is known about these complications in the vascular surgery population, a frail subset with multiple comorbidities. The objective of this study was to describe the contemporary incidence of RAEs in vascular surgery patients, the risk factors for this complication, and the overall impact of RAEs on patient outcomes. METHODS: The Vascular Quality Initiative was queried (2003-2014) for patients who underwent endovascular abdominal aortic repair, open abdominal aortic aneurysm repair, thoracic endovascular aortic repair, suprainguinal bypass, or infrainguinal bypass...

Impedance cardiography measurement of cardiac output gained wide interest due to its ease of use and non-invasiveness. However, validation studies of different algorithms yielded diverging results. Bioreactance (BR) as a recent adaption differs fundamentally as the flow signal is derived from phase shifts. Our aim was to assess the accuracy and reproducibility of BR, as compared to the non-invasive gold standard--cardiac magnetic resonance imaging (CMR). We prospectively included 32 stable patients. BR was performed twice in the supine position and averaged over 30 seconds...

Bile duct injuries (BDI) tend to be more complex in laparoscopic than in open cholecystectomy procedures, and frequently involve young adults with benign pathologies. The ultimate consequence may be a liver transplantation (LT), making this situation one of the most rare transplant indications. Fatal post-transplant outcome is extreme infrequently reported. Aim of this study is to report on our single-case experience and to review the literature concerning lethal outcome after LT for major BDI following cholecystectomy...

Currently methods to reduce radiation and contrast media application in endovascular repair of aortic aneurysms (EVAR) are investigated. First positive results for real-time contrast medium-enhanced ultrasonography (CEUS) guided endovascular aortic repair have been reported. A combination with image fusion of CEUS and preoperative multi-slice computed tomography (MS-CT) might offer added safety regarding stent-graft positioning and sealing of the landing zones.EVAR was performed in a patient with an asymptomatic infrarenal aortic aneurysm and a penetrating aortic ulcer in the neck region...

Aortic prosthetic valve endocarditis (PVE) is a potentially life-threatening disease. Mortality and incidence of infective endocarditis have been reduced in the past 30 years. Medical treatment of aortic PVE may be successful in patients who have a prompt response after antibiotic treatment and who do not have prosthetic dysfunction. In advanced stages, antibiotic therapy alone is insufficient to control the disease, and surgical intervention is necessary. Surgical treatment may be lifesaving, but it is still associated with considerable morbidity and mortality...

Aortic regurgitation resulting from blunt chest trauma has been reported only 95 times, to our knowledge. The noncoronary and right coronary cusps are the cardiac structures most often injured. Although the aortic leaflets can appear to be undamaged after nonpenetrating trauma, they can have pathologic abnormalities and insufficient function. Some cases of posttraumatic aortic regurgitation progress slowly. Aortic valve replacement is the optimal treatment. We present the case of a then-62-year-old man who has lived more than 5 years after blunt-trauma aortic regurgitation...

This study provides early results of re-operations after the prior surgical treatment of acute type A aortic dissection (AAD) and identifies risk factors for mortality. Between May 2003 and January 2014, 117 aortic re-operations after an initial operation for AAD (a mean time from the first procedure was 3.98 years, with a range of 0.1-20.87 years) were performed in 110 patients (a mean age of 59.8 ± 12.6 years) in seven European institutions. The re-operation was indicated due to a proximal aortic pathology in ninety cases: twenty aortic root aneurysms, seventeen root re-dissections, twenty-seven aortic valve insufficiencies and twenty-six proximal anastomotic pseudoaneurysms...
