  • Abstract
  • Look Inside

Prostacyclin (PGI2), a strong vasodilator of cerebralvesselsand a potent inhibitor of platelet aggregation, wasinfusedintravenously in 7 cats after induction of prolongedvaso-spasm by hourly application of oxyhemoglobinsolution intothe subarachnoid space around the basilar artery.PGI2,at a concentration of 50 ng/kg/min, was effective inreleasingthe vasospasm in the 7 cats. On the other hand,PGI2 didnot produce significant hypotension. This reportwilldiscuss our results and the probable mechanism ofactionof PGI2 in cerebral vasospasm.
