New Minimally Invasive Procedure Offers Brain Bleed Patients Safe  and Effective Alternative to Open Surgery

Dr. Kyle Chapple, a board-certified neurosurgeon at Atlantic NeuroSurgical Specialists (ANS), is the Principal Investigator for a new study focusing on the benefits of endovascular embolization for brain bleed patients.

Minimally invasive technique also enables treatment for previously inoperable brain bleeds

Patients suffering from subdural hematomas – the type of brain bleed most often caused by head injuries – have traditionally had two options. One option is open brain surgery, called a craniotomy, whereby a neurosurgeon removes part of the skull to access and treat the bleed. The other option is to leave the bleed alone and instead find a way to manage all of the symptoms, which can include dizziness, confusion, headaches, nausea, seizures and more.

Now, Dr. Kyle Chapple and the team of neurosurgeons at Atlantic NeuroSurgical Specialists (ANS) – one of the largest neurosurgical practices in New Jersey and one of the most advanced in the country – are advocating for a new, minimally invasive technique called endovascular embolization.

Endovascular embolization essentially enables neurosurgeons to safely and effectively treat subdural hematomas – brain bleeds located between the outside of the brain and the covering of the brain – without open brain surgery. Instead, a catheter is inserted in a large blood vessel at the top of a patient’s leg and navigated up into the blood vessels in the head. Through that catheter, microscopic particles called embospheres are delivered to stop the bleeding.

“Endovascular embolization is a procedure that we have used nearly every day at ANS over the past 20-plus years to treat patients with ruptured brain aneurysms and other conditions,” says Dr. Chapple. “Using the technique for subdural hematomas is very new to the medical community – and very promising. It can change the game for patients.”

The procedure offers a solution for a much wider range of patients than an open craniotomy. Not everyone is a candidate for a craniotomy, given limitations on the use of general anesthesia for older patients and those with health complications.

“This allows significantly more people who truly need surgical intervention to get it,” adds. Dr. Chapple. “Being a minimally invasive procedure, it also carries far fewer risks and potential side effects, and requires much less recovery time. In fact, patients can go home the very next day.”

With extensive early experience with the procedure, Dr. Chapple is the Principal Investigator for a new randomized study that compares patient outcomes from endovascular embolization versus traditional craniotomies.

He notes, “My colleagues and I have personally seen fantastic results in our patients who have undergone this procedure over the past few years, and we’re now in the process of generating formal medical research that we believe will support its safety and efficacy. I’m looking forward to helping drive insight on this innovative approach.”

Because the approach is so new and requires highly specialized expertise in endovascular neurosurgery, very few practices currently offer this procedure.
