A Surgical Case for Pregnancy-Related Spontaneous Coronary Artery Dissection.

The efficacy of coronary artery bypass grafting for pregnancy-related spontaneous coronary artery dissection (SCAD) is controversial, as graft occlusion due to SCAD lesion healing has been reported. Only 24 grafts in 14 cases of coronary artery bypass grafting for SCAD have been reported: 8 of the 9 arterial grafts were occluded, but 9 of the 15 vein grafts were patent. We encountered a case of coronary artery bypass grafting with left internal thoracic artery to the left antero-descending branch due to pregnancy-related SCAD. The patient's graft revealed good patency immediately postoperatively but string signs 7 months later due to healing of SCAD lesions.
