Abstract

Changes of major cerebral vessels in patients with subarachnoid hemorrhage (SAH) are well known from routine cerebral angiography. Data on changes in the microcirculation do not exist. This study sought to provide a qualitative and quantitative analysis of the cortical microcirculation after SAH. By means of orthogonal polarization spectral imaging, a qualitative and quantitative analysis of cortical microcirculation was performed during aneurysm surgery in 3 patients with an incidental intracerebral aneurysm and 10 patients with SAH. Vessel diameters, red blood cell velocity, and functional capillary density were analyzed before and after the aneurysm was clipped. Initial capillary density in patients with an incidental aneurysm was 91.5 +/- 36.5 cm(-1) (mean +/- standard deviation) compared with 30.5 +/- 13.8 in patients with SAH (P < 0.05). In patients with SAH, capillary density increased significantly to 53.9 +/- 29.1 cm(-1) (P < 0.05) during the operation, as did the frequency of venules with a red blood cell velocity greater than 2 mm/s (P < 0.05). No significant change of arteriolar or venular diameters was observed. However, in patients with SAH, mono- and multisegmental microvasospasms in arterioles were observed, wit...Continue Reading
