Patients may present with diarrhea, edema, ascites, or pleural effusions.
By regression analysis the presence of a fenestrated patch was the major determinant in the reduction in the amount and duration of postoperative effusion.
Under the simplest conditions a single flow is produced, but if effusion continues once the first flow has ceased, a multiple flow field may develop.
However, the results for pneumonia, neoplasm, and pleural effusion without congestive heart failure were not as strong.
Other abnormalities were: patent ductus arteriosus, septal hypertrophy, mitral valve prolapse and pericardial effusion (one case each).
Multiple flows are associated with a decrease in effusion rate, and new effusive episodes, starting with single flows, show increased effusion rates.
Subsequent lavas were less voluminous, with higher silica content and lower effusion rate, forming multiple flows.
Two patients had bilateral pleural effusions that resolved during the in-hospital period and one a left pneumothorax without consequences.
