Interventional Radiology Procedure Shown to Preserve Uterus in Women with Placenta Accreta

Researchers reported that a procedure can preserve fertility and potentially save the lives of women with a serious pregnancy complication called placenta accreta. New findings revealed that the positioning of balloons in the main artery of the mother’s pelvis before a Cesarean section protects against hemorrhage and is safe for both mother and baby.   More...

Meniscal Knee Surgery May Lead to Arthritis and Cartilage Loss

A widely used surgical procedure to repair meniscal tears may increase the risk of osteoarthritis and cartilage loss in some patients, according to new research. In the study, 100% of knees that had undergone surgery went on to develop arthritis, compared to 59% of those that had meniscal damage but did not have surgery.  More...

Many Chest X-Rays in Children Are Unnecessary

Researchers found that in some children who received chest X-rays, the screening may have been unnecessary and offered no clinical benefit. In addition, approximately 88% of pediatric X-rays for chest pain included in the study did not alter clinical treatment.  More...

Even Mild Coronary Artery Disease Places Diabetic Patients at Risk for Heart Attacks

According to a new long-term cardiac imaging study, diabetic patients with even mild coronary artery disease are faced with the same comparative risk for a heart attack or other major adverse heart events as diabetics with serious single-vessel obstructive disease. Previously, these patients were believed to have a lower risk of major adverse cardiovascular events and death than patients with obstructive CAD.  More...
