Potential hydromechanical forces influencing the degree of thrombus impaction. PProximal pressure on the proximal aspect of the clot; PDistal pressure on the distal aspect of the clot. PProximal pressure is increased by higher arterial pressure. PDistal pressure is increased by higher retrograde arterial pressure (e.g., collateral flow).
