“…Currently, the leading, long-term therapeutic strategy to treat severe, but not extremely urgent, obstructions in small-diameter vessels (lower than 6 mm), highlighting coronary arteries, consists of performing bypass grafting using autologous vasculature like the saphenous vein, radial arteries or internal thoracic artery ( Sánchez et al, 2018 ). Nevertheless, bypass grafting involving autologous vessels may not be suitable in many cases due to a range of circumstances (i.e., inappropriate graft size, previous diseases, unfavourable operation history or the multiple nature of the vascular occlusion) ( Cai et al, 2021 ; Georgakarakos et al, 2021 ). Additionally, other inconveniences should be highlighted, such as the vein graft failure due to stenosis ( Botelho et al, 2021 ).…”
