Quantitative digital angiography as an adjunct to the intraoperative placement of endovascular stents in congenital heart disease

Clearly identifiable intraoperative landmarks render the placement of intra operative stents difficult. Preoperative use of quantitative digital angiog raphy helps the surgeon accurately insert endovascular stents intraoperativ ely. By using defined points of reference, we were able to carefully select the size and lengths of stents before the operation and precisely place th ese stents in the operating room. Furthermore, we have been able to redilat e these stents using the same techniques at subsequent operations. Our resu lts reflect the efficacy of this technique.
