Stents, if
patentPatent ductus arteriosus, are likely to decrease collateral flow to the arteries in which they are in, thye will not affect distant arteries. This is not a problme because forward flow (throught the

Stent) and collateral flow are both driven by a pressure difference, so as long as there is forward flow, the collateral flow is no longer necessary. Again, stents do not inhibit collateral flow to the unstented arteries. EECP is done to alleviate chest pain from disease in arteries that are still diseased (unstented), therefore it is not contraindicated. Finally, stents have struts in them so they do not cover the openings of the diagonals, thereby, permitting continuous flow to those segements.
