We evaluated the feasibility, tolerability, and efficacy of a strategy for transaxillary artery intra-aortic balloon pump placement for extended mechanical circulatory support of patients with postcardiotomy shock as a bridge to recovery. Patients requiring prolonged intra-aortic balloon pump support for postcardiotomy heart failure were identified. Intra-aortic balloon pump was tunneled through a 6-mm Dacron graft anastomosed to the right axillary artery. The intra-aortic balloon pump catheter is advanced under fluoroscopic guidance into the descending thoracic aorta...

PURPOSE: Dilatation of the thoracic aorta is a well-known finding in corrected Tetralogy of Fallot. Complications are rare but can be life-threatening. Standard 1-dimensional (1D) measurements have several limitations. We sought to establish contrast-enhanced magnetic resonance angiography cross-sectional areas of the aorta that could serve as reference values and to identify parameters that are associated with aortic dilatation. MATERIALS AND METHODS: We enrolled 101 children and adolescents...

PURPOSE: Acute kidney injury (AKI) is a severe complication after infrarenal abdominal aortic aneurysm (iAAA) repair. Little data are available whether endovascular aneurysm (EVAR) or open aortic repair (OAR) differs with respect to AKI frequency and severity, consecutive development of chronic kidney disease (CKD) and potentially preventable and modifiable risk factors of AKI. PATIENTS AND METHODS: We assessed AKI rates, AKI stages and CKD applying current, complete definitions from the kidney disease improving global outcomes initiative in propensity-score-matched cohorts of all patients with elective and urgent iAAA repair at our institution from 2007 to 2011...

There is an unmet need for treatments to reduce abdominal aortic aneurysm (AAA) progression. Vascular smooth muscle cell (VSMC) apoptosis precipitates AAA formation, whereas VSMC proliferation repairs the vessel wall. We previously demonstrated that over-expression of EC4-Fc (truncated N-cadherin), or deletion of matrix-metalloproteinase-7 (Mmp-7) reduced VSMC apoptosis in mouse atherosclerotic plaques. Additionally, MMP-7 promotes VSMC apoptosis by cleavage of N-cadherin. We investigated their combined effect on AAA formation...

BACKGROUND: Readmission within 30 d of an acute hospital stay is frequent, costly, and increasingly subject to penalties. Early readmission is most common after vascular surgery; these patients are often discharged to skilled nursing facilities (SNFs), making postacute care an essential partner in reducing readmissions. We characterize 30-day readmissions among vascular surgery patients discharged to SNF to provide evidence for this understudied segment of readmission after specialty surgery...

The role of platelets in ischaemic events is well established. Aspirin represents the default antiplatelet and blocks the metabolism of arachidonic acid (AA) at the cyclo-oxygenase enzyme (COX). AA is commonly used as a test of response to aspirin, but recent data raise uncertainty about the validity of this approach. Specifically, in some patients AA-induced clotting is not suppressed, but the level of COX-dependent AA metabolite, thromboxane B2 (TXB2) is negligible. Furthermore, AA-induced whole blood clotting varies dynamically in individuals, who are aspirin responsive according to TXB2 levels...

Williams syndrome is a rare neurodevelopmental disorder characterized by mental retardation, growth deficiency, hypercalcemia, cardiac defects, and a distinctive facial appearance. Cardiovascular abnormalities are present in approximately 80% of Williams syndrome patients. Surgical treatment is generally performed for supravalvular aortic stenosis, aortic coarctation, pulmonary artery stenosis, or ventricular septal defect. In rare cases, diffuse hypoplasia of the aortic arch with a normal left ventricular outflow tract and ascending aorta may be diagnosed in early childhood...

Myocardial contusion and aortic injury are well-known cardiac complications of blunt chest trauma, but valvular injury is rare. Traumatic valve injuries most commonly involve the aortic valve, with isolated mitral valve injury being quite rare. We report a case of acute severe mitral regurgitation due to ruptured chordae tendineae requiring surgical repair following a motor vehicle accident.

Esophageal self-expandable metal stents and radiotherapy are valuable in combination for palliation and definitive treatment of esophageal cancer. However, risk of aortoesophageal fistula is significant in patients with evidence of malignant aortic invasion. Use of thoracic endovascular repair may represent an approach to early intervention in high-risk patients.

INTRODUCTION: Posterior spinal stabilisation is a technically demanding procedure which is increasing in popularity. Since this increase in popularity, complications, including screws misplacement, are being highlighted. Accuracy rates are higher when imaging modalities are used intra-operatively. Vascular injuries following posterior spinal stabilisation are rare and are usually discovered late on subsequent imaging. Immediate peri-operative compromise is rare, but nonetheless, resultant vascular injuries can be life threatening...
