Any factor which decreases either cardiac output or peripheral vascular resistance diminishes systemic arterial pressure and hence cerebral perfusion.
Consequently, careful cardiac and peripheral vascular examination should be undertaken in older syncopal patients.
Endothelial cells (en) receive signals from the podocytes to migrate into the vascular cleft and form glomerular capillaries.
Placental vascular resistance was then calculated from steady state pressure and flow data.
Nevertheless, severe pulmonary hypertension and elevated pulmonary vascular resistance were present.
Although rare, the possibility of cervical aortic arch and intrathoracic vascular pathology should be considered in patients with a large facial hemangioma.
Stereological evaluation of vascular adaptations of human placental villi to differing forms of hypoxic stress.
