Competitive Flow: Closure of Internal Thoracic Artery Graft After Successful Coronary Artery Bypass Graft SurgeryNovel Teaching Points
The internal thoracic artery has a patency rate of 85%-95% at 10-15 years post coronary artery bypass graft surgery. Development of total occlusion of the internal thoracic artery within a short period (< 6 months) after the surgery is exceedingly rare. However, competitive flow between the nativ...

| description | The internal thoracic artery has a patency rate of 85%-95% at 10-15 years post coronary artery bypass graft surgery. Development of total occlusion of the internal thoracic artery within a short period (< 6 months) after the surgery is exceedingly rare. However, competitive flow between the native vessel and the conduit internal thoracic artery, or competitive flow between the 2 conduit internal thoracic arteries in a multiple arterial grafting procedure can jeopardize 1 of the 2 conduit internal thoracic arteries. We report the cases of 2 patients who had bilateral internal thoracic artery grafts, with total occlusion of 1 of the 2 grafts within a short period (6 months) after successful coronary artery bypass graft surgery. Résumé: L’artère thoracique interne a un taux de perméabilité des greffons de 85 % à 95 % 10 à 15 ans après un pontage aortocoronarien. L’apparition d’une occlusion totale de l’artère thoracique interne dans un court délai (< 6 mois) après l’intervention est extrêmement rare. Cependant, le flux compétitif entre le vaisseau natif et l’artère thoracique interne de conductance ou le flux compétitif entre les 2 artères thoraciques internes de conductance dans une procédure de greffe artérielle multiple peuvent menacer l’une des 2 artères thoraciques internes de conductance. Nous rapportons les cas de 2 patients ayant subi une greffe bilatérale de l’artère thoracique interne et présenté une occlusion totale de l’un des 2 greffons peu (6 mois) après un pontage aortocoronarien réussi. |
