Future Perspectives in Small-Diameter Vascular Graft Engineering

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Cardiovascular Surgery

Background:

• Cardiovascular disease (CVD) presents a significant global health burden, with vessel narrowing or occlusion being common manifestations.
• Autologous grafts are used for damaged vessel replacement but have drawbacks, necessitating alternative solutions.
• The demand for small-diameter vascular grafts (SDVGs) drives research into tissue engineering approaches.

Purpose of the Study:

• To review current engineering approaches for small-diameter vascular grafts (SDVGs).
• To present state-of-the-art methodologies in SDVG development.
• To discuss future perspectives in SDVG engineering for cardiovascular reconstructive surgery.

Main Methods:

• Review of existing literature on small-diameter vascular graft (SDVG) engineering.
• Analysis of various materials including non-degradable/degradable and naturally derived options.
• Inclusion of decellularized vessels as a source for engineered SDVGs.

Main Results:

• Multiple SDVG engineering strategies are available, utilizing diverse biomaterials.
• Decellularized vessels offer a promising alternative source for SDVG development.
• Current methodologies represent the state-of-the-art in the field.

Conclusions:

• Engineered SDVGs hold significant potential to improve cardiovascular reconstructive surgery outcomes.
• Advancements in SDVG engineering can address the growing clinical need for effective vascular grafts.
• This field offers promising future perspectives for enhancing patient quality of life affected by CVD.
