Background Venous congestion in skin flaps is difficult to detect. This study evaluated the ability of tissue viability imaging (TiVi) to measure changes in the concentration of red blood cells (CRBC), oxygenation, and heterogeneity during vascular provocations in a porcine fasciocutaneous flap model. Methods In 5 pigs, cranial gluteal artery perforator flaps were raised (8 flaps in 5 pigs). ...

Pulmonary venous thromboembolism has only been identified as a cause of stroke with pulmonary arteriovenous malformations/fistulae, pulmonary neoplasia, transplantation or lobectomy, and following percutaneous radiofrequency ablation of pulmonary vein ostia in patients with atrial fibrillation. A 59-year-old man presented with a posterior circulation ischemic stroke. 'Unheralded' pulmonary vein...

Background: Glucose monitoring among critically-ill patients has been a topic of attention for long time to prevent both hyperglycemia and hypoglycemia, which is important in an intensive care unit. Use point blood glucose meters within some critically ill patient populations resulted varying degrees confusion about off-label use potential discrepancies results. The aim this study was compare t...

Anticoagulants have long been used for prevention and treatment of arterial venous thromboembolism (VTE). Vitamin K antagonists (VKAs), especially warfarin, were decades as the only available oral anticoagulants.

1. Angiotensin I1 together with any immunoreactive fragments of angiotensin were measured in arterial and venous plasma before and during infusion of angiotensin I1 amide in five normotensive subjects, both in sodium-replete and sodium-depleted states. Because the antibody used in the radioimmunoassay cross-reacted with larger angiotensin breakdown products and because these fragments are prese...

In this study oesophageal photoplethysmograph data from eight patients under positive pressure ventilation was analysed to test the hypothesis that the modulations created by the ventilation in the AC PPG single could be used to estimate the venous saturation. In order to estimate the instantaneous arterial and venous saturation Smoothed-pseudo WignerVille Distribution (SPWVD) was utilised. The...

Venous and arterial thromboses have traditionally been considered distinct pathophysiologic entities. However, the two disorders have many features in common, and there is evidence that persons with venous thrombosis may be at greater risk for arterial events. The pathogenesis of both disorders includes endothelial injury, platelet activation, elevated levels of intrinsic clotting factors and i...

AIM In this study, we sought to determine the early postoperative results of arterio-venous fistulae (AVF) created by U-vein compressors with veins between 1.5 and 2 mm in size. METHODS Pre-operative venous mapping was done. The fistula tract was marked at 0-, 4-, 8- and 12-cm points; 0 cm was the estimated point where the anastomosis would be done. With Doppler ultrasonography, transverse di...

OxLDL/β2GPI complexes have been implicated in the initiation and progression of atherosclerosis and associated with disease severity and adverse outcomes. We investigate the significance of anti-oxLDL/β2GPI antibodies and oxLDL/β2GPI complexes in patients with arterial and idiopathic venous disease. A cohort of 61 arterial disease patients, 32 idiopathic venous disease patients, and 53 healthy ...
