Reached for a comment, Ralph Sacco, MD, Department of Neurology, Miller School of Medicine, University of Miami, Florida, said the study indicates that doctors should perhaps "think more clearly about the time windows" for elective procedures following stroke. "If you can delay it, it may be worth delaying it for 9 months; if you can't, it may mean that you have to do it more carefully, paying attention to stroke preventative medications around the time of surgery."
He pointed out that stroke patients who are undergoing surgery often have medications discontinued before the procedure. "One medication we are always concerned about as neurologists is antithrombotic medications. Often they get discontinued because of the risk of bleeding with surgery, so maybe it does call into question whether, if possible, we could continue antithrombotic therapy around the time of surgery, if it's safe."
Dr. Sacco also said the quality of life of stroke survivors should be considered. Cosmetic surgery, such as breast reduction, is "truly elective" and could be postponed, but putting off hip replacement or lumbar surgery may mean leaving a patient in intractable pain and severely compromising his or her enjoyment of life. "It depends on how we define elective," said Dr. Sacco.
At the end of the day, he added, the study is important in that it alerts physicians to the increased risk for stroke and vascular events among stroke survivors following elective noncardiac surgery. "Stroke survivors are always at risk for a recurrent stroke, so we need to be more careful and more diligent about ways to prevent a second stroke among our stroke survivors, particularly around the time of elective surgery."
