Advanced Aneurysm Stent Means Safer Treatment

A new minimally invasive procedure has emerged as a safe way to treat certain brain aneurysms, and UConn Health’s Division of Neurosurgery is among its earliest adopters. The advancement, based on a stent that’s been in use for a decade, is known as the Neuroform Atlas.

“It’s a microstent,” says Dr. Ketan Bulsara, chief of UConn Health’s Division of Neurosurgery. “Sometimes the anatomy may prevent the navigation of a larger stent into the appropriate target area. The advantage of the microstent is, given its small size and smaller equipment requirements, we may be able to get into areas that we couldn’t normally navigate.”

That ability further broadens the range of lesion types that can be treated through minimally invasive means. Most patients who undergo this procedure can go home the following day.

An aneurysm occurs when part of an artery’s wall weakens, causing the artery to bulge. Aneurysms are usually asymptomatic but in some cases can rupture and cause life-threatening internal bleeding. When this occurs in blood vessels leading to the brain, it causes a hemorrhagic stroke, which requires emergency care.

Once an aneurysm is detected, it is important to get an assessment for its risk of rupture as soon as possible. Bulsara says about a third of patients who suffer a ruptured brain aneurysm die, and another third who make it to the hospital don’t fully recover.

“We’re in a time right now where the technological advancements in devices and microsurgical techniques are being made so rapidly that it’s imperative, to maintain the best possible outcome for all of our patients, that we offer the latest, newest technologies that have been deemed safe,” Bulsara says. “Our use of this stent is another testament to that. It continues to add to our treatment armamentarium and increases the number of diseases we can treat safely.”

The first Neuroform Atlas stent placement at UConn Health was among the 20 cases neurosurgeons completed in UConn Health’s new hybrid operating room within the first month of its opening.
