For the first time in Israel, A groundbreaking, first-of-its-kind surgery for drug-resistant epilepsy was performed at Hadassah Ein Kerem!
C., a 35-year-old mother of four from central Israel, has suffered for many years from severe epileptic seizures. She tried every standard medical protocol, but her recurring seizures continued, and her condition kept deteriorating.
The Epilepsy Center team at Hadassah Ein Kerem enabled her to undergo a unique surgery that, until now, had only been performed in the United States and Canada.
The procedure was led by Dr. Sami Hayman, epilepsy surgery specialist from the Department of Neurosurgery, Prof. Zvi Israel, Head of the Neurosurgery Department, and anesthesiologist Dr. Zaid Abu Armila.
After the precise location of her epileptic focus was identified, a neurostimulator was implanted in her brain. The device detects abnormal electrical activity and neutralizes it before it turns into a seizure.
“Without the implantation of this device, we would have had to remove the relevant area of the brain, with all the serious medical consequences such a procedure can cause,” says Prof. Dana Ekstein, Head of the Neurology Department at Hadassah, who has been treating C. for more than 15 years.
“This is truly personalized medicine - the RNS device is programmed specifically and precisely for C.’s brain.”
Following the implantation and healing period, the Epilepsy Unit at Hadassah will activate and program the neurostimulator to achieve the best possible results.
Hadassah is the only center in Israel that operates RNS device programming and runs an RNS programming clinic for patients who underwent the surgery abroad (primarily in the U.S.) and returned to Israel.
The clinic’s medical team includes Hadassah neurologists as well as Prof. Dawn Eliashiv, a world-renowned epilepsy specialist from UCLA.
“She is a married woman with four children. I accompanied her through difficult pregnancies, during which we had to care not only for her but also for the fetuses due to frequent falls. Over time, she had to rely more and more on a wheelchair, living with constant fear,” the team shared.
“But we didn’t give up. We embarked on a complex journey to find the exact brain region triggering her seizures. We understood that removing this area, as is often done, would almost certainly damage her vision. That is why we chose the RNS implant surgery. The procedure went smoothly and successfully. We knew this was the right solution for her- she had been waiting for it eagerly for months. We are now looking forward to activating the device and seeing the expected improvement in her condition.”
