The worst headache of her life

A 33-year-old woman had just entered her second trimester of pregnancy when her searing headache struck late last year.

Her obstetrician didn't know what was wrong with her. When the headache persisted a few days, he recommended that she have an MRI.

"There was an aneurysm on her internal carotid artery, the artery that supplies about half of the blood to the upper part of the brain. It’s an extremely critical artery," said Martin Luken III, a neurosurgeon at the Chicago Institute of Neurosurgery and Neuroresearch who is on staff at Ingalls.

When Luken met with the woman in the ER at Ingalls, she told him she was pregnant with her fourth child.

"She had a subarachnoid hemorrhage, the third leading cause of death in pregnant women," said Luken.

Luken had to operate to keep the aneurysm from exploding. He had the woman transferred to the high-risk obstetrical unit at Rush-Presbyterian-St. Luke's Medical Center in Chicago.

To prepare for the surgery, the doctors took an angiogram, which made the woman's blood vessels in her brain appear like glowing tree branches on the X-ray film. Luken and his surgical team could see exactly what they were up against and plot their strategy accordingly.

To get at the ballooning artery wall, they performed a craniotomy, cutting out a section of her skull that measured about half the size of a playing card. "You want to sneak up on this thing so it doesn't bleed, get the neck nicely exposed and very precisely apply the clip without compromising the blood flow in the carotid artery," he said.

Doctors also had to be mindful of the woman's unborn baby. A dip in the patient's blood pressure or problems with anesthesia could be fatal for the fetus.

The operation lasted seven hours, but the woman wasn't out of the woods yet.

"We had to keep our fingers crossed for several days to make sure she didn't have any complications," Luken said. "Sometimes with this surgery, patients have a successful operation, but the blood vessels might become irritated. They can clamp down so severely, it compromises circulation to the brain and people have a stroke."

A follow-up angiogram showed that the aneurysm which almost took her life had virtually disappeared.

A few months later, the woman was back in the hospital—not for an operation to save her life, but to give birth to a new one. "A healthy, baby girl," Luken stated proudly.
