28󈞘) who urgently needed embolization to control bleeding after a C-section were referred to the interventional radiology service at Brigham and Women's Hospital. Since bleeding complications after C-sections are uncommon, there was limited information as to the outcome of the different treatment methods. In a retrospective study, researchers analyzed trends or patterns in their hospital course and treatment outcomes, finding that this severe bleeding can happen either immediately after the C-section or up to several weeks after the delivery. A specific type of injury to the blood vessel known as a pseudoaneurysmwhich is a contained blood vessel rupturetends to show up later. "Overall, regardless of any of the clinical circumstances, bleeding following C-section was stopped promptly and effectively with minimal complications by embolization procedures performed by interventional radiology," said Stecker. He added, "Interventional radiology treatments avoid open surgery, general anesthesia, a long recovery time and other serious risk factors associated with surgical control of the bleeding. In preventing the need for hysterectomy, embolization may preserve a woman's uterus, allowing her to have other children."

Canadian researchers studied 14 women (ages 23󈞔) over a six-year period who were diagnosed with invasive placenta that was confirmed by a predelivery MRI. Interventional radiologists worked in a multidisciplinary team with obstetricians. The interventional radiologists guided balloon catheters into a woman's left and right uterine artery (preoperative prophylactic insertion of bilateral internal iliac artery occlusion balloons) before deliveryto be ready to inflate (just like in angioplasty), if needed at delivery to block excessive blood flow, explained interventional radiologist J. Robert D. Beecroft, M.D., who along with Kachura was a co-lead for the Mount Sinai study. "Often with massive bleeding, there is so much blood coming at t
