The condition for which Senator John McCain had surgery on Friday may be more serious than initial descriptions have implied, and it may delay his return to Washington by at least a week or two, medical experts said on Sunday.
The Senate majority leader, Mitch McConnell, has already announced that votes on a bill to dismantle the Affordable Care Act will not begin until Mr. McCains return. A statement released by Mr. McCains office on Saturday had suggested that he would be in Arizona recovering for just this week, but neurosurgeons interviewed said the typical recovery period could be longer.
The statement from Mr. McCains office said a two-inch blood clot was removed from above his left eye during a minimally invasive craniotomy with an eyebrow incision at the Mayo Clinic Hospital in Phoenix, following a routine annual physical. Surgeons there are not conducting interviews. Mr. McCains communications director, Julie Tarallo, said further information would be made public when it became available.
A craniotomy is an opening of the skull, and an eyebrow incision would be used to reach a clot in or near the left frontal lobes of the brain, neurosurgeons who were not involved in Mr. McCains care said.
Usually, a blood clot in this area would be a very concerning issue, said Dr. Nrupen Baxi, an assistant professor of neurosurgery at the Albert Einstein College of Medicine in New York City.
He added, The recovery time from a craniotomy is usually a few weeks.
A statement from the Mayo Clinic Hospital said that the senator was recovering well and in good spirits at home, and that tissue pathology reports would come back in several days.
