Potential of PRP in Vascular Diseases

PRP (Platelet-Rich Plasma) has rapidly gained popularity in the medical field in recent years. Similar to stem cell therapies, PRP is derived from the patient's own blood and aims to accelerate natural healing processes. PRP's applications range from orthopedics, dermatology, aesthetic surgery, and sports medicine, and its potential in treating vascular diseases is increasingly being researched. This article will examine the potential of PRP in the treatment of vascular diseases and review the scientific findings in this area.

What is PRP and How is it Prepared?

PRP is a plasma obtained from the patient's own blood, rich in platelets. Blood is separated into its components via centrifugation; in this process, the part rich in red and white blood cells is removed, leaving behind plasma rich in platelets. Platelets contain growth factors that play a significant role in injury and healing processes. These growth factors promote cell regeneration, increase collagen production, and support the formation of new blood vessels.

Effects of PRP on Vascular Diseases

Improvement of Endothelial Function

The underlying cause of vascular diseases is often endothelial cell dysfunction. Endothelial cells line the inner surface of blood vessels and play a crucial role in vascular health. PRP, with its growth factors, can promote the regeneration and improvement of endothelial cell functions. Research has shown that PRP increases endothelial cell proliferation and promotes their migration, leading to healthier and more functional vessel linings.

Formation of New Blood Vessels (Angiogenesis)

One of the growth factors in PRP, VEGF (Vascular Endothelial Growth Factor), plays a significant role in the angiogenesis process. Angiogenesis means the formation of new blood vessels and is critical, especially in ischemic (insufficient blood flow) areas. PRP applications can promote the formation of new blood vessels in ischemic tissues, helping to meet the oxygen and nutrient needs of these regions. This characteristic presents therapeutic potential, particularly in conditions like peripheral artery disease.

Reduction of Inflammation

Chronic vascular diseases are often associated with chronic inflammation. PRP can reduce this inflammation through its anti-inflammatory effects. The growth factors and cytokines in PRP can regulate the inflammation process and accelerate healing. In conditions like chronic venous insufficiency, the anti-inflammatory effect of PRP can alleviate symptoms and improve patients' quality of life.

Applications of PRP in Vascular Disease Treatment

Peripheral Artery Disease

Peripheral artery disease (PAD) is characterized by decreased blood flow to the legs, often resulting from atherosclerosis. PAD manifests as difficulty walking, leg pain, and ulcers. PRP therapy can improve circulation in PAD patients and promote new vessel formation, helping to alleviate symptoms and contribute to healing. Clinical studies have observed that PRP increases blood flow in the legs and accelerates ulcer healing.

Chronic Venous Insufficiency

Chronic venous insufficiency (CVI) occurs when leg veins cannot effectively return blood to the heart. This disease causes symptoms such as swelling, pain, skin changes, and ulcers in the legs. PRP therapy can help alleviate symptoms in CVI patients by reducing inflammation and accelerating tissue healing. Clinical findings support that PRP applications promote ulcer healing in CVI patients.

Diabetic Foot Ulcer

Diabetic foot ulcers are a common and difficult-to-heal type of wound in diabetic patients. These ulcers can be resistant to treatment due to poor blood circulation and infection risk. PRP can accelerate wound healing in diabetic foot ulcers. The growth factors in PRP support cell regeneration and collagen production, aiding wound healing. Studies have shown that PRP therapy reduces infection risk and accelerates the healing process in diabetic foot ulcers.

Advantages and Limitations of PRP Therapy


  1. Natural and Biological: PRP is derived from the patient's own blood, minimizing the risk of allergic reactions or infections.

  2. Low Side Effects: The side effects of PRP therapy are generally minimal and short-term.

  3. Rapid Healing: PRP can accelerate natural healing processes, helping patients recover more quickly.


  1. Lack of Standard Protocol: There is no standardized protocol for PRP applications yet, which can lead to variability in treatment outcomes.

  2. Insufficient Clinical Data: Clinical data proving the effects of PRP on vascular diseases are still limited, requiring further research.

  3. Cost: PRP therapy can be expensive for some patients and may not be covered by insurance.

PRP presents promising potential in the treatment of vascular diseases. Its effects on improving endothelial function, promoting new blood vessel formation, and reducing inflammation indicate that PRP can be used for conditions like peripheral artery disease, chronic venous insufficiency, and diabetic foot ulcers. However, more clinical research is needed to establish the efficacy and safety of PRP therapy. Further studies in this field will clarify PRP's place in the treatment of vascular diseases.
