PULMONARY hypertension associated with end-stage liver disease and portal hypertension can pose a number of serious management problems. One such problem during surgery for liver transplantation is sudden circulatory collapse 1-3 . We report the use of manual compression of the abdominal aorta to increase arterial pressure and coronary perfusion after severe hypotension in a patient with pulmonary hypertension undergoing orthotopic liver transplantation.
