Implication

Observational study reveals lower mean cerebral blood flow in patients with hypertensive intracerebral hemorrhage and mass effect, indicating impaired hemodynamics correlate with clinical severity.

Key Points

To evaluate regional cerebral blood flow patterns and vascular reactivity in patients following hypertensive intracerebral hemorrhage.
Measured regional cerebral blood flow using the 133 Xe clearance technique in 44 patients within three weeks of hypertensive intracerebral hemorrhage onset.
Categorized hematomas as lateral (n=35) or mesial (n=9) and assessed focal vascular response to 5% carbon dioxide inhalation and cerebral angiography.
Mean cerebral blood flow was lower in patients with more disturbed consciousness and was significantly reduced in lateral-type hematomas with space-occupying signs (n=14) compared to those without (n=21).
Relative hyperemic regions appeared in 16 patients across focal and nonfocal areas, while relative ischemic zones occurred in seven patients, primarily in nonfocal tissue.
Early venous filling occurred exclusively in 13 lateral-type cases, though only 4 demonstrated good correlation between angiographic findings and cerebral circulation.
