Slow venous return

WebbLeft ventricular stroke volume also falls because of reduced pulmonary venous return (decreased left ventricular preload). This causes cardiac output (CO) and mean arterial pressure (MAP) to fall. If arterial pressure falls appreciably upon standing, this is termed orthostatic or postural hypotension. Webb1 mars 2016 · Spontaneous Retroperitoneal Hematoma from Lumbar Vein Retroperitoneal hematoma is a rare clinical condition, with an incidence of 0.1%, and as high as 0.6% in patients receiving oral anticoagulation therapy.
