McCain’s blood clot may be more significant than first thought

Sen. John McCain, 80, is recovering at his Arizona home following surgery on Friday to remove a blood clot above his left eye, according to his office. The clot was discovered during a routine physical last week, according to a statement.

Surgeons at Mayo Clinic Hospital in Phoenix “successfully removed the 5-cm blood clot during a minimally invasive craniotomy with an eyebrow incision,” the statement said.
An eyebrow incision is not a big deal, explained CNN Chief Medical Correspondent and practicing neurosurgeon Dr. Sanjay Gupta, but the bone was opened to gain access to the brain, Gupta explained on CNN’s New Day Monday.

“It’s a significant operation,” he said, adding that general anesthesia was used and “there was obviously an abnormality that was concerning enough for him to go through this.”

The New York Times also reported Monday that McCain’s surgery may be more serious than first described. Medical experts quoted by the newspaper said it may delay his return to Washington by at least a week or two.

Gupta prefers to refer to the clot as an “abnormality” because lab results are still pending and, “it’s a pretty significant size of compression on that part of the brain.”
But the location of the clot could be indicative of something more. “The operation seems to have gone well, but one thing worth noting is that Senator McCain has a history of invasive melanoma in and around that area,” Gupta said.

The clot was over the senator’s left eye, not far from the left temple where he was diagnosed with melanoma in 2000. The big concern is that this blood clot could signal a recurrence, according to Gupta.

“They’re calling it a blood clot. When it’s removed, you want to look at it specifically under the microscope and see if there’s anything that indicated this could be melanoma. You try to remove this early and aggressively,” he said.

The diagnosis in 2000 was not McCain’s only history of skin cancer. He previously had three other malignant melanomas…
