The Blood hammer phenomenon is a sudden increase of the upstream blood pressure in a blood vessel (especially artery or arteriole) when the bloodstream is abruptly blocked by vessel obstruction. The term "blood-hammer" was introduced in cerebral hemodynamics [1] by analogy with the hydraulic expression.[2] "water hammer", already used in vascular physiology to designate an arterial pulse variety, the "water-hammer pulse".[3]
