GREENWICH – Greenwich Hospital has successfully performed its first high-intensity focused ultrasound (HIFU) procedure, offering groundbreaking relief for patients suffering from essential tremor. The neurological condition that causes uncontrollable shaking, as well as tremor-dominant Parkinson’s disease.
The non-invasive procedure utilizes state-of-the-art technology to target and disrupt tremor-causing brain tissue with precision, providing a transformative option for those whose lives are impacted by the condition. The milestone underscores Greenwich Hospital’s commitment to advancing medical innovation and enhancing patient outcomes in the region.
During the treatment, under MRI guidance, sound waves are precisely focused on the small spot in the patient’s brain considered to be responsible for causing tremors. Low energy is first applied, which allows the patient to inform the physician of any sensations they feel or other potential side effects. Then the physician can make individualized adjustments to the target. The energy is gradually increased to create a small therapeutic lesion.
For many patients, like Deborah Ewen of Old Greenwich, the result is an immediate improvement of tremors in the treated hand. Ewen, who suffered from the tremors for nearly 40 years, was the hospital’s first patient to undergo the procedure.
“I’m excited to not have to figure out ways to hide my tremors,” Ewen said. She received treatment for tremors on the right side of her body and is eligible for treatment to the left side of her body in approximately nine months.
Greenwich Hospital neurosurgeon Dr. Zion Zibly and Dr. Alice Rusk oversaw the procedure. They are both associate professors at Yale School of Medicine.
“It was a fabulous outcome for the patient,” said Dr. Rusk. “She has dealt with this condition for many years and has a very strong family history with essential tremors. The collaboration with Dr. Zibly was fantastic and we are so happy the patient is doing so well.”
Ewen was overcome with emotion after the procedure. Tears of joy fell down her face as she fed herself and drank water while presenting no tremors.
Before the procedure, Ewen was asked to complete an exercise that included drawing spirals and a line, as well as writing her name. Afterwards, she was asked to complete the same exercise, and the improvement was as clear as day. With her husband Ward by her side, Ewen expressed her appreciation for everyone involved.
“I’m so grateful,” she said.
