摘要

Background

Coronary artery aneurysms are focal dilatations that exceed the diameter of normal adjacent vessels by a factor of at least 1.5-fold. Multimodal imaging is essential when attempting to improve the efficacy of curative interventions in aneurysm patients as it can facilitate the comprehensive functional and anatomical characterization of these intricate vascular lesions.

Case summary

In this report, we describe the case of a patient with giant diagonal branch aneurysms accompanied by obstructive coronary artery disease. Successive coronary artery bypass grafting (CABG) and surgical resection were performed to effectively treat these conditions, and these procedures were aided by the use of three-dimensional (3D) printed models of the heart.

Conclusion

Employing computed tomography-guided reconstruction procedures in combination with the use of multiplanar, multicolor 3D printed models can enable surgeons to better assess the dimensions, source, and relationships of target vessels with adjacent tissues, thereby ensuring that preoperative planning can be completed more effectively.
