Since the beginning of the 'microvascular era', the success rates of microvascular procedures have increased to more than 90% in most series. The main reason for failure, however, is the healing of microarterial anastomosis, which is dependent on the status of endothelial cells and affects the rate of arterial thrombosis. ...

Axillary artery cannulation is indicated mainly during surgery involving the aortic root and the aortic arch when the pathology precludes a standard cannulation of the ascending aorta. Axillary cannulation provides an antegrade systemic flow, allows easy initiation of antegrade cerebral perfusion during circulatory arrest and reduces the rate of retrograde ...

A fundamental physics-based derivation of intraspecific scaling laws of vascular trees has not been previously realized. Here, we provide such a theoretical derivation for the volume-diameter and flow-length scaling laws of intraspecific vascular trees. In conjunction with the minimum energy hypothesis, this formulation also results in diameter-length, flow-diameter and flow-volume ...

Non-thrombotic pulmonary embolism (NTPE) is commonly defined as the partial or total occlusion of the pulmonary circulation caused by a variety of non-thrombotic embolic agents. Although its prevalence is much lower than that of pulmonary thromboembolism, this life-threatening pathology is often underestimated due to the low specificity of signs and ...
