Monofilament absorbable sutures in median sternotomy

Area of Science:

• Cardiovascular Surgery
• Biomaterials Science

Background:

• Steel sutures are standard for median sternotomy closure but present complications like breakdown, sternal erosion, infection, and cosmetic issues.
• Alternative materials like silk, polyester, and polypropylene have risks including infection and granulation tissue formation.
• Previous absorbable sutures had short absorption times, leading to sternal infection and dehiscence; newer monofilament sutures offer longer absorption.

Purpose of the Study:

• To evaluate the safety and efficacy of a novel monofilament absorbable suture material for median sternotomy closure.
• To compare the outcomes of using monofilament absorbable sutures versus traditional steel sutures in open heart surgery.

Main Methods:

• A prospective study involving 153 sternal closures using a monofilament absorbable suture material.
• Patients underwent the procedure at Koşuyolu Heart and Research Hospital over a seven-month period.
• Patient demographics included a mean age of 32.55 years and a mean body weight of 48.37 kg.

Main Results:

• Only two cases of sternal dehiscence were observed in the 153 patients.
• This indicates a low complication rate associated with the monofilament absorbable suture.

Conclusions:

• Monofilament absorbable suture material is a safe and effective alternative to steel sutures for sternotomy closure.
• The findings support the use of this material across various patient populations in cardiac surgery.
