Which statement is accurate concerning plain catgut sutures?

Plain catgut sutures are indeed absorbable, which means they can break down in the body over time without the need for removal. This property makes them particularly useful for internal suturing where long-term support is not necessary, as the body will naturally absorb these sutures, promoting healing while avoiding additional surgical procedures.

Absorbable sutures, like catgut, are typically made from natural materials, which allows for gradual absorption as the tissues heal, making them advantageous for various surgical applications. This characteristic aligns with the nature of plain catgut sutures, setting them apart from synthetic sutures, which do not offer this same absorbable quality and instead may require removal after tissue healing.

The other statements do not accurately reflect catgut sutures; they either describe properties not applicable to catgut, such as being synthetic or having strong tensile strength predictability, which is less consistent compared to synthetic alternatives. Additionally, the tendency toward tissue vascularization is a separate consideration that does not inherently define the absorbable nature of plain catgut sutures.
