Characterization of contractile responses to endothelin in human cerebral arteries: implications for cerebral vasospasm.

abstract：:The placement of the atrial portion of a ventriculoatrial shunt is occasionally rendered difficult by a tendency of the shunt catheter to pass into the contralateral jugular vein or into a subclavian vein instead of into the atrium. We report a simple flow-directed technique that may resolve this problem. ...
