Abstract
Background
It is believed that increased intracranial pressure immediately after subarachnoid hemorrhage (SAH) causes extensive brain ischemia and results in worsening clinical status. Arterial flow to the cerebral surfaces is clinically well maintained during clipping surgery regardless of the severity of the World Federation of Neurological Societies grade after SAH. To explore what kinds of changes occur in the cortical microcirculation, not at the cerebral surface, we examined cortical microcirculation after SAH using two-photon laser scanning microscopy (TPLSM).
Methods
SAH was induced in mice with an endovascular perforation model. Following continuous injection of rhodamine 6G, velocities of labeled platelets and leukocytes and unlabeled red blood cells (RBCs) were measured in the cortical capillaries 60 min after SAH with a line-scan method using TPLSM, and the data were compared to a sham group and P-selectin monoclonal antibody-treated group.
Results
Velocities of leukocytes, platelets, and RBCs in capillaries decreased significantly 60 min after SAH. Rolling and adherent leukocytes suddenly prevented other blood cells from flowing in the capillaries. Flowing blood cells also decreased significantly in each capillary after SAH. This no-reflow phenomenon induced by plugging leukocytes was often observed in the SAH group but not in the sham group. The decreased velocities of blood cells were reversed by pretreatment with the monoclonal antibody of P-selection, an adhesion molecule expressed on the surfaces of both endothelial cells and platelets.
Conclusions
SAH caused sudden worsening of cortical microcirculation at the onset. Leukocyte plugging in capillaries is one of the reasons why cortical microcirculation is aggravated after SAH.

Comments
The authors provided a very elegant study on the pathophysiology of the cortical microcirculation after subarachnoid hemorrhage (SAH) in a rodent model. They very clearly demonstrated that when a sudden increase of intracranial pressure (ICP) begins after SAH, blood cell velocities in the capillaries decrease significantly and “rolling” and adherent leukocytes plug capillaries, preventing other blood cells from flowing. According to the results here provided, this is the consequence of an ICP rise that determine the compression of capillaries and decrease of blood flow. This in turn causes cerebral ischemic damage and an inflammatory response. This study provides robust evidence about the subsistence of this pathophysiological event and interesting illustrations. Further studies to demonstrate the translational potential of these findings are warranted. In particular, it is true that an abrupt ICP rise is present after SAH. Nevertheless, this cortical dysfunction might be present only in severe SAH cases. I wonder whether it is the persistently elevated ICP, present in severe SAH grades, instead of an abrupt rise with a quick fall that plays a major role. An indication of the intensity and the duration of the ICP rise able to induce such microvessel paralysis would be desirable. Thus, the authors are invited to continue their studies and provide further data on this interesting issue.
