[en] Thoracic aortic calcium deposits are frequently detected on tomography of the chest, and in other imaging modalities. Numerous studies indicated the correlation of hemodynamic parameters such as wall shear stress in relation to distribution aortic calcifications. This publication discusses similarities and differences of two distinct pathomechanisms of arterial calcifications: intimal associated with atherosclerosis and medial knows as Mönckeberg’s arteriosclerosis. This review also analyzes the frequent coexistence of aortic calcification and coronary artery disease in terms of risk of cardiovascular events
[en] After reviewing the basic principles of NMR imaging, the authors discuss their current work correlating arterial wall morphology and composition to in-vivo MRI images and the initial results using this modality in a clinical setting. 15 refs.; 14 figs
[en] This paper describes thirteen stenotic arteries treated by high-speed rotary abrasive burr atherectomy performed in the operating room under fluoroscopic-angioscopic control by a multidisciplinary team consisting of a vascular surgeon, an interventional radiologist, and an interventional cardiologist. Incrementally sized atherectomy burrs were used in each patient (1.75-4.0 mm in diameter). Rotary artherectomy was successful in 11 of 13 arteries ranging from 1 to 40 cm (median, 5 cm) with stenoses ranging from 50% to 99% (median, 90%), which improved to less than 30% in all 11 successfully atherectomized segments. Two early posttreatment failures (intimal dissection, burr shaft disruption), two posttreatment thromboses (unrelated to atherectomy), and two late failures (restenosis) occurred
[en] BackgroundEndovascular treatment is considered a reasonable approach for patients with acute posterior circulation stroke, but it remains uncertain which patients will benefit the most from it.
[en] Persistent sciatic artery is a rare congenital anomaly. It is associated with increased incidence of aneurysmal dilatation, thrombosis, distal embolization, and atherosclerotic change. We describe the case of a patient with persistent sciatic artery who presented with a critically ischemic left leg as a result of an occluded left common iliac artery, which was treated by angioplasty and stenting, and discuss the endovascular iliac recanalization in the presence of a persistent sciatic artery.
