Strokes, Climbing, and New Tech: A Chicago Story
Lucas Wittwer was only 27 when a fall at a climbing gym left him unconscious. He woke up feeling fine, but doctors later uncovered a hemorrhagic stroke caused by an aneurysm. The episode erased his memories of the days doctors performed a delicate embolization to seal the aneurysm.
During National Stroke Awareness Month, Wittwer joined staff from the University of Chicago Medical Center and Philips for a behind‑the‑scenes event. The hospital highlighted that stroke risk has risen 50 % over the past twenty years—a trend mirrored by rising cases among people of color on Chicago’s South Side.
Warning Signs to Watch For
- Dizziness
- Blurred vision
- Facial droop
- Speech trouble
Doctors stress the strong link between high blood pressure and stroke risk, urging patients to manage hypertension and adopt healthier diets.
Treatment Advances
- Reperfusion therapy now restores blood flow after a heart attack and is used for strokes, helping patients regain brain function quickly.
- New imaging rooms let doctors begin procedures without waiting for a traditional CT scan.
Procedures now often use tiny wires and catheters inserted through the wrist or groin to remove clots or repair aneurysms. These minimally invasive techniques can take only minutes, and experts predict that artificial intelligence may one day let specialists perform them remotely, expanding care to rural areas.
Wittwer’s own procedure lasted about thirty minutes due to its complexity, but he has since returned to climbing. “I’m really lucky,” he says, and he’s back on the wall again.
