Description
Yuko Tsurumi, with six colleagues, reports a 2026 case where an ultrasound probe inside a neck artery caught a problem the X-ray missed. Stenting a narrowed carotid artery can leave plaque or clot poking through the stent, a source of stroke during the procedure. Dye-based angiography is the standard final check, yet it can overlook such pokes.
The patient was a 92-year-old Japanese man with two tight spots in his right carotid artery. After stenting under balloon protection, the dye check looked clean. The ultrasound probe, though, showed a marked poke inside the far stent. A second overlapping stent, placed at once under renewed blockage, flattened the poke on a repeat probe check. The man recovered well and went home on day four. The authors back probe checks to guide rescue.
