The femoral artery remains the access of choice in the majority of peripheral vascular interventions. However, specific conditions indicate catheterization of the brachial artery. In contrast to balloon catheters the majority of stent delivery systems are too short to facilitate transbrachial implantation of self-expandable stents (SES) in the superficial femoral ...

Abstract Aneurysmal subarachnoid hemorrhage (SAH) is a common condition treated by neurosurgeons. The inherent variability in the incidence and presentation of ruptured cerebral aneurysms has been investigated in association with seasonality, circadian rhythm, lunar cycle, and climate factors. We aimed to identify an association between solar activity (solar flux and ...

Many studies proved the prognostic importance of aortic stiffness as an independent predictor of cardiovascular morbidity and all-cause mortality. The decrease of arterial compliance has a high prevalence in patients with heart failure and affects both hemodynamics and prognosis. Aortic stiffness is partially caused by excessive activation of the renin-angiotensin-aldosterone ...
