Nitric oxide: implications for vascular and endovascular surgery

Area of Science:

• Cardiovascular Biology
• Vascular Surgery
• Biomedical Engineering

Background:

• Nitric oxide (NO) is vital for maintaining vascular homeostasis.
• NO exhibits protective functions against vascular smooth muscle cell proliferation in conditions like atherosclerosis and restenosis.
• It possesses significant antiplatelet and anti-thrombogenic properties.

Purpose of the Study:

• To review the applications of nitric oxide in vascular and endovascular surgery.
• To explore strategies for leveraging NO's therapeutic potential in surgical practice.

Main Methods:

• Review of existing literature on nitric oxide's role in vascular health.
• Analysis of various NO delivery and enhancement strategies.
• Examination of clinical applications in vascular interventions.

Main Results:

• Nitric oxide (NO) is essential for vascular homeostasis and possesses anti-proliferative, anti-platelet, and anti-thrombogenic effects.
• Systemic NO donors, L-arginine supplementation, and gene therapy can enhance endogenous NO production.
• Local delivery strategies, including NO-releasing coatings for stents and grafts, show promise.

Conclusions:

• Nitric oxide (NO) offers significant therapeutic potential for vascular and endovascular surgery.
• Strategies for enhancing NO bioavailability and delivery can improve outcomes in vascular interventions.
• Further research into NO-based therapies is warranted for clinical application.
