White House press secretary James S. Brady has had no further complications since the insertion of a metal sieve on Monday to prevent blood clots from reaching his lungs, and may be able to sit up and move around again next week.

Since April 27, Brady's doctors have had him lying in one position, moving only a little from side to side, to allow healing of a passage from the nose through the sinuses to the interior of his skull. Since then no more fluid has leaked from Brady's nose -- the signal that first warned doctors that the passage was open -- according to Dr. Dennis O'Leary, dean for academic and clinical affairs at George Washington University Hospital.

O'Leary said Brady is awake and alert, has no fever, and that skull X-rays done Wednesday morning showed that almost all the air that had collected around his brain has not been absorbed. "There's just one small bubble left up there now," he said.

He said Brady's enforced immobility has made it impossible to do much testing of his control of muscles of the left arm and leg, which was most affected by his wound. His immobility may also have contributed to his most recent complication, the passage of some small blood clots from his legs to his right lung early this week.
