A 14-year-old with end-stage renal disease presents for emergent hemodialysis after missing two sessions. One hour into treatment, he becomes restless, complains of severe frontal headache, and begins vomiting. His blood pressure increases from 118/70 to 162/92 and he is now increasingly confused. Physical exam shows no focal deficits. The HD catheter site is clean and dry, and the dialysis circuit shows no air. Which hemodialysis-related complication is the most likely cause of this patient’s symptoms?
