this case study reports a rare variation of the superior laryngeal artery (sla), which is the principal arterial supply of the larynx. the knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. during routine dissection of an adult male cadaver, a rare arterial variation in the sla was seen. in this case, the sla passed through ...

OBJECTIVES This study sought to assess sex differences in ventricular-arterial interactions. BACKGROUND Heart failure with preserved ejection fraction is more prevalent in women than in men, but the basis for this difference remains unclear. METHODS Echocardiography and arterial tonometry were performed to quantify arterial and ventricular stiffening and interaction in 461 participants with...

Coronary artery bypass grafting (CABG) is the optimal surgical treatment for multi-vessel coronary artery disease. CABG operation has successful shortand intermediate-term results, but the long-term results are variable. The variability of results in long-term particularly depends on the nature of the vascular grafts used. Angiographic studies in long-term have showed that patency rates of arte...

BACKGROUND Cardiovascular magnetic resonance (CMR) has been validated for the noninvasive assessment of total arterial compliance and aortic stiffness, but their associations with cardiovascular outcomes is unknown. The purpose of this study was to evaluate associations of CMR measures of total arterial compliance and two CMR measures of aortic stiffness with respect to future cardiovascular ev...

A radioactive isotope dilution technique, in which two radioactive tracers were used simultaneously, was employed to investigate the nature of the hepatic arterial vascular bed or arterial vascular "space" in 22 isolated perfused canine livers. The technique continuously monitored the blood leaving the liver for radioactivity so that no assumptions had to be made regarding the representative na...

Measurement of cerebral arterial and venous blood volumes during increased cerebral blood flow can provide important information regarding hemodynamic regulation under normal, pathological, and neuronally active conditions. In particular, the change in venous blood volume induced by neural activity is one critical component of the blood oxygenation level-dependent (BOLD) signal because BOLD con...
