A 63-year-old woman presented with a symptomatic aneurysm and a pelvic transplant kidney on the side of an external iliac artery occlusion. A commercially available bifurcated endograft was introduced through the common iliac artery contralateral to the kidney. The external iliac artery occlusion required antegrade delivery of an iliac limb ...

The information needed to diagnose pulmonary arterial hypertension (PAH) in dogs based on N-terminal pro B-type natriuretic peptide (NT-proBNP) and atrial natriuretic peptide (ANP) levels is unclear. In this study, serial changes in plasma NT-proBNP and ANP concentrations were evaluated in association with the development of chronic embolic pulmonary hypertension ...

The management of congenitally corrected transposition of the great arteries and associated lesions is frequently challenging. Restrictive ventricular septal defect and mild pulmonary stenosis are contraindications to the double switch procedure, including the atrial-Rastelli switch procedure, due to the production of postoperative left ventricular outflow tract obstruction. We describe a ...

We report an unusual case of intrapericardial diaphragmatic hernia 2 years after coronary artery bypass surgery with the right gastroepiploic artery. Herniation through the orifice created for the right gastroepiploic artery caused small bowel strangulation and secondary volvulus requiring extensive small bowel resection due to acute mesenteric ischemia. This case highlights ...

Vascular ring anomalies (VRA) are relatively uncommon cardiovascular disorders in canine patients. The most common VRA is a persistent right aortic arch (PRAA) with a left ligamentum arteriosum, however various other vascular anomalies resulting in tracheoesophageal compression have also been reported. We report a case of a dog with a ...

The specific role of different isoforms of the Na,K-pump in the vascular wall is still under debate. We have previously suggested that the α2 isoform of the Na,K-pump (α2), NCX and connexin43 form a regulatory microdomain in smooth muscle cells (SMCs), which controls intercellular communication and contractile properties of the ...

Velocity-selective (VS) arterial spin labeling is a promising method for measuring perfusion in areas of slow or collateral flow by eliminating the bolus arrival delay associated with other spin labeling techniques. However, B(0) and B(1) inhomogeneities and eddy currents during the VS preparation hinder accurate quantification of perfusion with VS ...

Fibrillar collagen endows the normal aortic wall with significant stiffness and strength and similarly plays important roles in many disease processes. For example, because of the marked loss of elastic fibers and functional smooth cells in aortic aneurysms, collagen plays a particularly important role in controlling the dilatation of these ...

An anomalous pulmonary vein anatomy could represent a challenge for the thoracic surgeon. In these cases, the incidence of complications during lung surgery is increased, especially the need to perform a pneumonectomy due to a wrong section of the vascular elements. All attempts to reduce this risk must be undertaken, ...

Knowledge of morphometric quantities of coronary arteries in infants is an increasingly vital component in managing congenital and acquired heart disease. Because of considerable heterogeneity of coronary vasculature, what is considered atypical and aberrant or insignificant anatomy is often unclear. The purpose of our present study is to define normal ...
