Prolene is a synthetic, non-absorbable polypropylene suture material widely used in surgery. It is known for its high tensile strength, minimal tissue reactivity, and long-term durability. Prolene is commonly used in various surgical procedures, including cardiovascular surgery, plastic surgery, and general surgery.

Properties

Prolene sutures are made from an isotactic crystalline stereoisomer of polypropylene, which gives them their unique properties. These sutures are characterized by their:

• High tensile strength
• Minimal tissue reactivity
• Resistance to degradation by tissue enzymes
• Smooth surface, which facilitates easy passage through tissues

Uses

Prolene is used in a variety of surgical applications due to its favorable properties. Some of the common uses include:

• Cardiovascular surgery: Prolene is often used for anastomosis of blood vessels and for suturing prosthetic grafts.
• Plastic surgery: It is used for skin closure and for suturing delicate tissues.
• General surgery: Prolene is used for abdominal wall closure, hernia repair, and other soft tissue approximations.

Advantages

Prolene offers several advantages over other suture materials:

• Long-term durability: Prolene sutures do not degrade over time, making them suitable for long-term tissue approximation.
• Minimal tissue reaction: The inert nature of polypropylene minimizes the inflammatory response, reducing the risk of infection and promoting better healing.
• High tensile strength: Prolene maintains its strength over time, providing reliable wound support.

Disadvantages

Despite its many advantages, Prolene has some limitations:

• Handling characteristics: Prolene can be more difficult to handle compared to other suture materials due to its stiffness and memory.
• Knot security: Achieving secure knots with Prolene can be challenging, requiring additional throws to ensure stability.

History

Prolene was developed in the mid-20th century as part of the search for better synthetic suture materials. Its introduction revolutionized surgical practice by providing a reliable, non-absorbable option for tissue approximation.
