摘要：A method and a device for the intermittent or continuous measurement ofportal blood pressure using a tamponade balloon inserted into the esophagus andstomach and a sensor positioned on the bridle, tamponade shaft or esophageal balloon.The tamponade balloons mounted over a tube are placed across the diaphragmatichiatus and are gradually inflated through a lumen that runs from the balloons to aposition that is external from the patient. The measured pressure within the tamponadeis increased until the blood flow in the collateral portal veins that traverse the diaphragmare occluded. The cessation of the blood flow into the esophageal varices is signaledwhen the sensor identifies a change in diameter of the varices, a change in the color ofthe esophageal wall, or a change in velocity of blood flow. The measured tamponadepressure at the nadir of variceal blood flow is equivalent to portal blood pressure.
