New bypass surgery for stroke riskier than thought
USA Today

To prevent stroke in certain high-risk patients — those with a blocked neck artery who have already had a so-called “mini-stroke” — drug treatment appears as effective and far less risky than bypass surgery, researchers find. Their study evaluated nearly 200 patients, about half of whom had carotid artery bypass surgery. In the 30 days after surgery, patients had a 14 percent risk of having a stroke, compared with a 2 percent risk among those treated medically, the study found.
