Successful bailout stenting strategy against rare spontaneous retrograde dissection of partially absorbed magnesium-based resorbable scaffold: A case report

Figure 1 Intravascular ultrasound 8 mo prior, optical coherence tomography and coronary angiography findings. A-C: The treated segments are proximal cross-section (A), middle cross-section (B), distal cross-section (C). Post-implantation intravascular ultrasound images of the magnesium-based metal scaffolds show good apposition of struts. Real-time optical coherence tomography pullbacks vividly demonstrate almost complete resorption of the struts at the 8^th month. MRS: Magnetic resonance spectroscopy; LAD: Left anterior descending artery.

Figure 2 Coronary angiography images. A: Edge vascular response adjacent to the distal edges after implantation of fully magnesium-based resorbable scaffold; B: Optimal balloon angioplasty; C: Coronary dissection occurs with rapid spreading out (in antero-cranial view).

Figure 3 Optical coherence tomography images. A: Proximal cross-section; B: Middle cross-section; C: Distal cross-section. Optical coherence tomography results are consistent with the estimates of the prior image study and showed good apposition struts.
