Radiation arteritis is a rare cause of lower extremity peripheral arterial occlusive disease, and has been traditionally treated with open interventions. There have been only a few reported cases of endovascular interventions for this disease. Previous reports described endovascular treatment in the iliac and common femoral regions, but intervention in the superficial femoral artery have not been described. Described here is a case of acute lower extremity ischemia caused by remote radiation arteritis of the superficial femoral artery, which was successfully treated by percutaneous endovascular technique...

: Large elastic arteries stiffen with age which predisposes older adults to increased risk for cardiovascular disease. Aerobic exercise training is known to reduce the risk for cardiovascular disease, but the optimal exercise prescription for attenuating large elastic arterial stiffening in older adults is not known. PURPOSE: The purpose of this randomized controlled trial was to compare the effect of all-extremity high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on aortic pulse wave velocity (PWV) and carotid artery compliance in older adults...

Neurofibromatosis type I (NFI), also called Von Recklinghausen disease, is an autosomal dominant disease secondary to a genetic mutation on the long arm of chromosome 17. This disorder affects neural crest cells. Cutaneous clinical forms are the most frequent with multiple benign skin neurofibromas, associated with café au lait skin spots and iris hamartomas. Vascular abnormalities in NF1 are rare but have also been well described. The most frequent abnormalities are characterized by arterial aneurysm degeneration, stenosis, and malformations...

Stent implants are essential in restoring normal blood flow in atherosclerotic arteries. Recent studies have shown high failure rates of stent implants in superficial femoral artery (SFA) as a result of dynamic loading environment imposed on the stent implants by the diseased arterial wall and turbulent blood flow. There are variety of stent designs and materials currently on the market however, there is no clear understanding if specific stent design is suitable with the material that is manufactured from and if this combination can sustain the life-cycle that the stent implants need to undergo once inside the artery...

BACKGROUND: Radial artery is now the most frequent access for coronary angiography and intervention. Despite the common opinion that it is safer than femoral access, it has the potential for serious complications. One of them is upper limb ischemia caused by radial artery thrombosis. CASE REPORT: We are presenting a case of critical hand ischemia after coronary angiography performed through radial access despite existing risk factors, which may be considered as relative contraindications...

An anatomically detailed model consisting of a network of electric transmission lines is developed to simulate propagation of the pulse waves in humans. The simulations show that the real arterial tree geometry, together with the elastic and rheological parameters of particular segments, ensure an efficient protection of vital organs against pulse waves generated at peripheral locations. Because locomotive movements are the most obvious source of such disturbances, additional cyclic perturbations are applied to the model femoral arteries...

A 38-year-old man was found unconscious, alone in the driver's seat of his car. The emergency medical team identified his condition as pulseless ventricular tachycardia. Defibrillation was attempted but failed. Extracorporeal membrane oxygenation (ECMO) was started in the emergency room 52 min after the estimated arrest following the extracorporeal cardiopulmonary resuscitation (ECPR) protocol in our center. The initial prognosis under the standard protocol was <25% chance of survival. A novel adjunctive to our ECPR protocol, cerebral selective deep (<30°C) hypothermia (CSDH), was applied...

BACKGROUND: Allogeneic skin tissues are highly antigenic and induce intensive immune rejection after composite tissue allotransplantation. Mouse models have advantages in mechanistic studies of immune rejection. However, due to technical challenge in vascular anastomosis with suture technique, mouse vascularized skin allotransplantation models are not widely used in studies of immune rejection. Therefore, the authors propose vascular anastomosis through cuff technique during allotransplantation of mouse donor free groin skin flaps to either recipient inguinal or cervical site...
