They bridge between the proximal and distal parts of a coronary artery which is chronically occluded in between. Presence of bridging collaterals, though physiologically useful for providing distal perfusion, could create problem during attempts of percutaneous coronary intervention. A guidewire passed from the proximal segment, instead of passing into the occluded segment, is likely to take the easy way out into the bridging collaterals.<\/p>\n<p>The coronary angiogram shows bridging collaterals in a post coronary artery bypass right coronary CTO. Sternal wires indicate the post CABG status. A short segment of the right coronary artery is not opacified. The missing segment is bridged by small bridging collaterals.<\/p>\n<p>In a comparative study using conventional coronary angiography and computed tomography, bridging collateral were documented in 15% by coronary angiography while none were picked up by CT [1]. A study of over thousand six hundred CTOs showed that success rate of PCI declined with the presence of bridging collaterals [2].<\/p>\n<p><strong><span style=\"color: #0000ff;\">References<\/span><\/strong><\/p>\n<ol>\n<li>Singh S, Singh N, Gulati GS, Ramakrishnan S, Kumar G, Sharma S, Bahl VK. <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24740894\">Dual-Source Computed Tomography for Chronic Total Occlusion of Coronary Arteries<\/a>.
