Polyglycolic Acid Sutures

Polyglycolic acid (PGA) sutures are a type of synthetic absorbable suture that are commonly used in medical procedures. PGA sutures are made from a biodegradable polymer that breaks down over time and is absorbed by the body. They are widely used for wound closure and tissue approximation, and are often preferred over other types of sutures due to their strength and biodegradability. In this article, we will provide an overview of PGA sutures, their properties, uses, and other important information.

Properties Of PGA Sutures

PGA sutures are made from a synthetic polymer that is composed of repeating units of glycolic acid. They are characterized by their strength, which is greater than that of many other types of synthetic absorbable sutures, such as polylactic acid (PLA) and polydioxanone (PDS). This strength allows PGA sutures to maintain tissue apposition for longer periods of time, which can aid in wound healing.


PGA sutures also have a predictable degradation rate. The degradation process of PGA sutures is hydrolysis, which is the breakdown of the polymer by water molecules. This process typically takes between 60 and 90 days, depending on the size of the suture and the location in which it is placed. The degradation of PGA sutures results in the formation of lactic and glycolic acids, which are metabolized by the body and excreted as carbon dioxide and water.

Uses Of PGA Sutures

PGA sutures are widely used in a variety of surgical procedures, including general surgery, orthopaedics, gynaecology, urology, and cardiovascular surgery. They are particularly useful in procedures where long-term wound support is required, such as in abdominal or thoracic surgeries. PGA sutures are also commonly used in ophthalmic surgery, as they are well tolerated by the delicate tissues of the eye.


PGA sutures are often used in conjunction with other types of sutures, such as non-absorbable sutures or monofilament sutures, depending on the specific needs of the patient and the surgical procedure. They are typically used for wound closure, tissue approximation, and ligation of blood vessels.

Other Important Information

PGA sutures are available in a variety of sizes and lengths, ranging from 4-0 to 2-0 in diameter. They are also available in a variety of needle types, including round bodied, taper point, and cutting needles. The specific needle type used will depend on the surgical procedure being performed and the preference of the surgeon.


Like all types of sutures, PGA sutures carry a risk of infection and other complications. It is important to use proper surgical technique and sterile conditions when placing PGA sutures to minimize this risk. It is also important to monitor the healing of the wound and to remove any sutures that have not been absorbed by the body after the appropriate amount of time has passed.


In conclusion, polyglycolic acid surgical sutures are a widely used type of synthetic absorbable sutures that are characterized by their strength and predictable degradation rate. They are commonly used in a variety of surgical procedures and are particularly useful in procedures where long-term wound support is required. As with all types of sutures, proper surgical technique and sterile conditions must be maintained to minimize the risk of infection and other complications.
