Examples of vascular

• 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.

• Vascular access in previously catheterised children and adolescents: a prospective study of 131 consecutive cases.
