Willis Knighton Health First in State to Have Same Day Discharge after Endovascular Embolization of Aneurysm
February 19, 2026Willis Knighton Health is the first healthcare organization in the state to treat intracranial aneurysm with the minimally invasive WEB™ Aneurysm Embolization System for same-day discharge. Ashish Sonig, MD, director of Willis Knighton Neurovascular Institute, performed the procedure at Willis Knighton Heart & Vascular Institute at Willis Knighton North.
The 62-year-old patient experienced blurred vision, headache and a family history of aneurysms, which put her at high risk. Tests showed an intracranial brain aneurysm in the right internal carotid artery bifurcation. She had a successful procedure and post-operative recovery and was safely discharged home the same day.
“Minimally invasive treatment of aneurysms is now the standard of care, although some aneurysms will still need open brain surgery,” said Dr. Sonig, who is dual trained to perform both open neurosurgery and endovascular/minimally invasive procedures to treat complex conditions of the brain and spine. “Same day discharge for procedures using WEB™ Aneurysm Embolization System will be decided on a case-by-case basis.”
The WEB™ Aneurysm Embolization System is designed as an intra saccular device, meaning it sits inside the aneurysm and double anti-platelet therapy can be avoided. This may allow for same-day discharge on a case-by-case basis. The procedure is performed by placing a catheter in the groin or wrist and delivering the self-expanding mesh ball implant into the sac of the aneurysm to disrupt blood flow entering the aneurysm.
The WEB™ Aneurysm Embolization System represents a significant advancement in neuroendovascular surgery.
A brain aneurysm occurs when the wall of an artery in the brain becomes weak, bulges outward and fills with blood. If the aneurysm ruptures, it can cause life-threatening bleeding in the brain and hemorrhagic stroke symptoms that require emergency treatment. An estimated 6.8 million people in the United States have an unruptured brain aneurysm. Most do not cause symptoms or require treatment. Roughly 30,000 people in the U.S. suffer ruptured brain aneurysms each year.
