The angiosome concept as a model for decision-making in revascularization of patients with critical limb ischemia has fallen victim to a lively discussion in recent years. Therefore, the aim of this prospective pilot study was to provide further data on the angiosome concept on the level of microcirculation after tibial bypass surgery by using intraoperative fluorescence angiography.

Traditional contrast media are problematic in advanced chronic kidney disease. Ultrasmall superparamagnetic particles of iron oxide (ferumoxytol) are safe in chronic kidney disease and have been used for imaging in other settings. We tested the feasibility of ferumoxytol-enhanced magnetic resonance angiography (FeMRA) in patients with renal failure and performed a dose-finding study.

Carotid artery disease is a major cause of stroke. The in vivo computed tomography calcified and noncalcified plaque structural components that connote carotid plaque rupture and symptoms remain ill-defined for a given degree of stenosis. We therefore analyzed computed tomography angiography (CTA) images of symptomatic patients enrolled in the Plaques at Risk (PARISK) study designed to determine the natural history of carotid stenosis (30%-70%) causing ipsilateral neurologic events.

Thoracic endovascular aortic repair (TEVAR) is the first-line treatment of complicated acute type B aortic dissection (ATBAD). Transesophageal echocardiography (TEE) is fundamental in diagnostic and intraprocedural phases; otherwise, its role seems to be limited in case of abdominal aortic extension. Intravascular ultrasound (IVUS) with established diagnostic features may be useful in guiding endovascular procedures. A systematic literature search on the use of imaging tools was aimed at verifying the contribution of IVUS, TEE, angiography, and intraluminal phased-array imaging in the management of ATBAD.

AbstractPurpose of ReviewThe aim of this article is to review the role of imaging in pre-procedural assessment prior to transcatheter aortic valve replacement (TAVR) —with a focus on relevant anatomic findings apart from the size of the aortic annulus.Recent FindingsPre-procedure imaging prior to TAVR heavily emphasizes assessment of the aortic annulus for appropriate valve sizing, with computed tomography angiography (CTA) emerging as the test of choice due to its ability to assess not only the aortic annulus but also the thoracoabdominal aorta and peripheral vasculature. Some patients with underlying kidney disease...

ConclusionsConfidence with the anatomic pattern and clinical significance of this anomalous condition is necessary to improve cardiac imaging evaluation ability. In our patient, coronary computed tomographic angiography proved to be a reliable imaging approach, superior to invasive coronary angiography in terms of diagnostic performance and patient safety.

Authors: Tao X, Liu Y, Chen J, Xu L, Zhou Z, Lei H, Yin Y Abstract BACKGROUND Moyamoya disease (MMD) is an idiopathic disease caused by progressive steno-occlusion of the distal internal carotid artery. Ideal surgical treatment for adult patients with ischemic-type MMD has not been achieved. The aim of this study was to evaluate the efficacy of single-barrel superficial temporal artery-middle cerebral artery (STA-MCA) bypass in treatment for adult patients with ischemic-type MMD by analyzing clinical and radiological data retrospectively. MATERIAL AND METHODS The present study included 37 patients with non-hemorrha...
