A retrograde approach via the collateral channel has been recently proposed to improve the success rate of PCI in CTO lesions of the coronary arteries. We describe an accidental complication encountered during transradial PCI to recanalize right coronary artery CTO in a patient with unstable angina. A long spiral dissection has been created by antegrade wiring and extended from the ostium all the way down to mid RCA segment. Subsequent attempts with antegrade wiring into the true lumen were unsuccessful. <jats:italic>Ad\u2010hoc<\/jats:italic> retrograde recanalization has been employed to rescue the vessel via septal collateral from left anterior descending artery. Retrograde wiring and dilatation were performed followed by successful antegrade wiring into the true lumen under IVUS guidance, which revealed significant intramural hematoma extending distally to the posterolateral branch. Bailout stenting was achieved with sealing of the multiple entry and exit sites created by the spiral dissection and complete coverage of the intramural hematoma. This report highlights the role of the retrograde approach as a rescue option in the setting of complicated antegrade approach and to improve the success rate of CTO\u2010PCI. Moreover, IVUS was a valuable tool to confirm the true lumen course of the successful wire and to guide the stenting procedure. \u00a9 2012 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ccd.24606","type":"journal-article","created":{"date-parts":[[2012,8,17]],"date-time":"2012-08-17T05:29:23Z","timestamp":1345181363000},"source":"Crossref","is-referenced-by-count":3,"title":["Transradial retrograde approach rescuing iatrogenic long spiral dissection during chronic total occlusion intervention"],"prefix":"10.1002","volume":"83","author":[{"given":"Sayed M.","family":"Abdou","sequence":"first","affiliation":[{"name":"Cardiology Department National Heart Institute Cairo Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hon Kan","family":"Yip","sequence":"additional","affiliation":[{"name":"Division of Cardiology Department of Internal Medicine Chang Gung Memorial Hospital, Kaohsiung Medical Center, Chang Gung University College of Medicine Taiwan Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiung\u2010Jen","family":"Wu","sequence":"additional","affiliation":[{"name":"Division of Cardiology Department of Internal Medicine Chang Gung Memorial Hospital, Kaohsiung Medical Center, Chang Gung University College of Medicine Taiwan Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,10,21]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2004.12.065"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(01)01349-3"},{"key":"e_1_2_4_4_1","first-page":"571","article-title":"Recanalization strategy for chronic total occlusions with tapered and stiff\u2010tip guidewire.
