Worth Repeating...

“The current differences in CRC screening guidelines raise practical questions not only about what doctors and patients should do in the face of disagreement, but also about the larger process by which guidelines are made and how ‘trustworthy’ they may be.”

—Thomas F. Imperiale, MD, and David F. Ransohoff, MD, from “Understanding Differences in the Guidelines for Colorectal Cancer Screening” in the March issue of Gastroenterology

E-Editor’s E-Note


One of most interesting things about attending the Society of Interventional Radiology meeting is seeing how the researchers in this subspecialty develop treatments where they didn’t previously exist. Whether doctors had tried all available treatments or the patient is not a candidate for surgery—as described below—it has to be rewarding for the physicians who conceive, develop, and deliver ways to treat people who had basically run out of good options.

Reducing Stroke Risk

A device using two angioplasty balloons to temporarily block blood flow to the brain while placing carotid stents in high surgical-risk patients offers a safe and effective way to prevent stroke from occurring during treatment, according to research released at the Society of Interventional Radiology’s 35th Annual Scientific Meeting in Tampa, Fla. last month.

“The Mo.Ma device, which uses balloons that are inflated and act like endovascular surgical clamps to protect the brain during the procedure, provides a treatment option for patients who may not be healthy enough to undergo surgery—for example, those with severe heart or lung disease or those who have had neck operations or radiation for neck tumors,” said Barry T.
