UCI Health offers minimally invasive laser surgery to preserve brain function
Approach can minimize risk of damaging nearby healthy tissue
September 29, 2015
Adding a laser to his surgical toolkit enables UCI Health neurosurgeon Dr. Sumeet Vadera to operate on epilepsy patients for whom surgery has not been an option. For some patients, medication does not control their seizures, which originate in a part of the brain that would be damaged by surgery, causing speech or physical impairment.
Visualase is a minimally invasive surgical tool that precisely targets the brain abnormality and destroys it by directly delivering infrared laser light without harming the healthy surrounding tissue.
“Lesions that were difficult to access with standard surgery can now be treated,” Vadera said. “We don’t have to make big incisions. Using a brain scan image, we plan our surgical path. The infrared laser light travels down an optical fiber, destroying the target tissue with heat, without damaging blood vessels or harming healthy tissue.”
UC Irvine Medical Center is one of the first Southern California hospitals to offer Visualase, which can also be used to treat brain tumors, masses and lesions. Vadera was trained to use Visualase at Cleveland Clinic prior to joining UCI Health last year. Since September 2014 he has performed four successful operations using Visualase.
“Lasers have several advantages over standard surgical tools,” Vadera said. “Precise anatomical targeting is possible, so no skull flap is required and the use of other treatment options is not limited. Lesions that would otherwise require a large craniotomy and open brain surgery can now be treated using a minimally invasive procedure.”
The Visualase procedure combines a powerful MRI imaging system and laser light energy. A laser applicator is guided through a small pinhole in the patient’s skull, through the layers of brain tissue and into the lesion. The surgeon uses the MRI to monitor the temperature of the brain tissue. The laser light raises the temperature of the lesion until it is destroyed, while healthy tissue is protected. The applicator is removed and the incision closed, usually with one stitch.
