Description
Wenwen Chen, Xiu Shen, and Yindan Yao published this case report in 2025. A seventy-year-old woman came to hospital with episodes of weakness in her left arm and leg. Scans showed severe narrowing of a major brain artery, and she started two blood-thinning drugs. On day three, doctors performed an angiogram, injecting dye into her neck arteries. One artery was unusually small.
During steady dye injection into that small vertebral artery, a tiny branch feeding the spinal cord ballooned and burst. Dye flooded the space around the cord, and a scan confirmed widespread bleeding around the brain. The team managed her with medicines alone for ten days. Follow-up scans showed the bleeding had cleared. She left hospital without major deficits and stayed free of new bleeding over three years of checks. The authors blame sustained high-pressure injection and warn against probing such small arteries.
