conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

Τransradial artery access has recently gained widespread acceptance as the preferred approach for coronary angiography and interventions, due to its lower incidence of bleeding vascular complications compared transfemoral access. However, thrombotic occlusion radial emerged most common complication this method, impeding use in future creation arteriovenous fistulae hemodialysis patients, or a g...

Synthetic vascular grafts are used in a wide range of clinical applications. However, they can become prone to occlusion over time, due the growth smooth muscle cells (VSMCs). This phenomenon is associated with graft failure. Here, we describe novel techniques for packaging and integration miniature sensor VSMC growth. The was based on microfabricated array interdigitated platinum electrodes si...

High-fidelity recordings of left ventricular (LV) pressure and its corresponding first derivative (dP/dt), electrocardiogram, and systemic arterial pressure were obtained intraoperatively following insertion of aortocoronary saphenous vein bypass grafts in eight men. During sequential 3-min periods, the bypass grafts were, in turn, open, occluded by vascular clamps, and opened by releasing the ...

An 85-year-old man was found to have a 9 cm diameter true aneurysm of an obtuse marginal saphenous vein graft. The graft was fed by a relatively narrow neck from the proximal remnant of the obtuse marginal graft 10 years after prior coronary artery bypass graft surgery. An Amplatzer vascular plug was used successfully to occlude the neck of the aneurysm. Follow-up CT scan 1 month afterward demo...

arteriovenous fistulae traditionally have been placed in the upper extremity. experience with groin hemodialysis access has been discouraging because of high infection rates and associated limb amputation. the aim of this study was to determine infection rates, patency rates, and possible predictive factors for prosthetic thigh angioaccess outcomes in our hemodialysis patient population. a pros...

uncontrolled hypertension is well- known to give rise to systemic complications involving multiple central organs. artherosclerosis leads to damage of the retinal vessels wall, contributing to venous stasis, thrombosis and finally, occlusion. retinal vein occlusions compromise vision through development of ischaemic maculopathy, macular oedema, and rubeotic glaucoma. laser photocoagulation rema...

Background—The purpose of this investigation was to determine optimal patient and target-vessel characteristics to maximize arterial and venous graft patency on the basis of data from a large clinical trial. Methods and Results—Angiographic data on 440 radial artery grafts and 440 saphenous vein grafts were analyzed with methodology to account for within-patient clustering. Multivariable models...

ObjectiveDifferent graft materials have been proposed for in situ reconstruction the setting of vascular infection (VGI). We analyzed long-term outcomes after aortoiliac with cryopreserved allografts.MethodsWe performed a retrospective analysis patients who had undergone arterial allografts VGI from 2000 to 2015. The end points were perioperative and mortality graft-related complications, inclu...
