The condition for which former President Bill Clinton will undergo elective surgery on Thursday is a complication that occurs in fewer than 1 percent of coronary bypass patients, his doctors said yesterday.
The complication, in which fluid and scar tissue compress and collapse a lobe of the left lung, is not expected to recur, the doctors said at a news conference at NewYork-Presbyterian/Columbia University Medical Center.
The doctors said they expected that Mr. Clinton "will resume his work without limitations" within a month. Doctors not involved in Mr. Clinton's care agreed that the complication was unusual and did not pose serious long-term problems. All the doctors interviewed expected him to recover fully and quickly.
One heart surgeon not associated with the case, Dr. Konstadinos Plestis of Montefiore Medical Center in the Bronx, said that irritation from even a small amount of fluid collecting in the chest after bypass surgery could lead to the formation of a layer of tissue that can cover the left lower lobe of the lung like a thick sock.
"That can squeeze the lung down," Dr. Plestis said.
The squeezing prevents the lung from inflating fully and causes shortness of breath, which Mr. Clinton had noticed. Mr. Clinton will undergo general anesthesia for what his doctors said is a low-risk procedure.
But when asked to specify the risk on a scale of 1 to 10, Dr. Joshua Sonnet, a chest surgeon who will perform Mr. Clinton's operation, did not give an answer. To free the lung, surgeons must peel off the thickened tissue in an operation that takes about two hours, Dr. Plestis said.
One of the first steps in the surgery, to give doctors room in which to work, is to collapse the lung, which is done with a special breathing tube that blocks air supply to one lung. Dr. Plestis said that to remove the thickened tissue, doctors normally try the least invasive method first, inserting a miniature video camera and surgical tools between the ribs through three small punctures in the chest.
If that approach does not provide enough access, they must make an incision in the chest, about three inches long, and spread the ribs. The open operation is usually faster than the one using the camera, but it is more painful.
In addition to the usual risks of surgery, like infection and bleeding, Mr. Clinton's operation can cause tiny injuries that let air leak out of the lungs. Dr. Plestis estimated the risk of leaks at 20 percent to 30 percent. The injuries heal, but patients are usually kept in the hospital until the leaks have stopped, he said.
Dr. William Follansbee, a cardiologist at the University of Pittsburgh, said that fluid and inflammation in the chest after bypass surgery could sometimes be cleared up with drugs, and that only a minority of patients needed surgery.
Dr. Follansbee said the problem did not mean the original surgery had been done improperly. Some people may be more prone to accumulate fluids and develop irritation and inflammation.
But once Mr. Clinton is treated, he said, there is no reason to believe the problem will recur. The operation can take one to three hours, depending on the complexity of the surgery.
Mr. Clinton first noticed symptoms from the complication about a month ago when he began getting winded more easily during his exercise program of walking six to seven miles a day over a hilly course near his home in Chappaqua, N.Y. Mr. Clinton also felt discomfort in his left chest.
The combination of the two problems as well as findings from examining his chest and X-rays led the doctors to recommend the surgery, called decortication, said Dr. Alan Schwartz, the chief of cardiology at NewYork-Presbyterian/Columbia.
CT scan X-rays showed a decrease of about 25 percent in Mr. Clinton's lung volume and a larger, but unspecified, decrease in lung function. There was no sign of infection; irritation of the pericardium, or covering of the heart; or pneumothorax, a different type of lung collapse than what he has, the doctors said.
Because Mr. Clinton passed an exercise stress test "with flying colors" - he scored in the 95th percentile for a 58-year-old man - the doctors considered the timing of the procedure elective. So they said he could safely travel to Indonesia on Feb. 19 with former President George Bush to tour South Asian nations devastated by the Dec. 26 tsunami.
If Mr. Clinton does not have the procedure, there would be a small risk that the collapsed area of the lung could become infected.
Dr. Craig R. Smith, the cardiac surgeon who led the team that performed Mr. Clinton's bypass operation on Sept. 6, estimated that fewer than 10 patients among the 6,000 on whom he has performed bypass operations have needed surgery for the complication that Mr. Clinton experienced.
Most patients develop fluid in the lungs after bypass and other chest surgery, but the body usually absorbs it in time without need for surgery. Sometimes diuretic and anti-inflammatory drugs help.
"What has happened here is the extremely unusual end result of an extremely common process," Dr. Smith said.
Dr. Smith said he was "quite sure" that he did not tell Mr. Clinton about the risk of this complication because it was so low.
The Bubbafucco Legacy !
Collapsed lung and surgery are recipes for intense pain.
LOL! Lord have mercy. The Lord knows what he deserves.
So he's walking 6 to 7 miles a day.
If his walking distances are anything like his golf scores, me thinks that walking to the mail box is the extent of his exercise.
