A Minimally Invasive Option for Subdural Hematomas: What Patients Need to Know

Subdural Hematoma

For years, treatment options for subdural hematomas—a type of brain bleed most commonly caused by head trauma—were limited. The standard approach was open brain surgery (craniotomy), which carries significant risks, especially for older patients or those with other health conditions. But today, an innovative, minimally invasive procedure is changing the game.

At Atlantic Brain and Spine, board-certified neurosurgeon Dr. Kyle Chapple and his team are offering endovascular embolization—a safe and effective alternative that’s opening the door to treatment for patients who previously had few or no options.

What Is a Subdural Hematoma?

A subdural hematoma occurs when blood collects between the outer surface of the brain and the dura mater (the brain’s protective covering). It can develop gradually or suddenly, often after a head injury, and symptoms may include:

  • Headaches
  • Dizziness
  • Confusion or memory problems
  • Nausea
  • Seizures
  • Weakness or difficulty speaking

While some cases resolve on their own, others require surgical intervention—especially when the bleed causes pressure on the brain.

A Less Invasive Option: Endovascular Embolization

Endovascular embolization allows neurosurgeons to treat subdural hematomas without open surgery. Instead of removing part of the skull, a tiny catheter is inserted through a blood vessel in the leg and guided to the bleeding site in the brain. There, microscopic particles (embospheres) are delivered to stop the bleeding at its source.

This technique has long been used to treat brain aneurysms and other vascular conditions. Its application to subdural hematomas is a newer innovation—and it’s showing promising results.

Who Can Benefit?

Many patients who would be considered high risk for open surgery—including older adults or those with other medical issues—may be good candidates for this minimally invasive approach.

Benefits of endovascular embolization include:

  • No need for general anesthesia
  • Fewer complications and side effects
  • Faster recovery times
  • In many cases, patients go home the next day

Is It Effective?

Dr. Chapple has successfully performed this procedure in numerous cases and is currently the Principal Investigator in a clinical study comparing outcomes between endovascular embolization and traditional craniotomy. Early data supports the procedure’s safety, effectiveness, and long-term benefits.

“This approach is making a real difference in the lives of patients who previously had very limited options,” says Dr. Chapple. “We’re seeing excellent outcomes and significantly faster recoveries.”

What to Do If You or a Loved One Has a Subdural Hematoma

If you’ve been diagnosed with a subdural hematoma—or are experiencing symptoms that could indicate a brain bleed—it’s important to act quickly. Not all neurosurgical practices offer endovascular embolization, as it requires specialized training and technology.
