Sternal closure with resorbable synthetic loop suture material in children.

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiac Surgery
• Surgical Materials Science

Background:

• Sternal closure is a critical step in open-heart surgery.
• Traditional non-absorbable sutures carry risks of infection and dehiscence.
• Evaluating absorbable sutures for sternal closure is essential for improving patient outcomes.

Purpose of the Study:

• To assess the reliability and safety of poly-p-dioxanone (PDS) suture for sternal closure.
• To determine the incidence of sternal wound complications and mediastinitis using PDS suture.
• To compare the efficacy of PDS suture with standard sternal closure techniques in pediatric cardiac surgery.

Main Methods:

• A retrospective analysis of 264 consecutive sternotomies performed between April 1987 and May 1998.
• Patients underwent sternal closure using poly-p-dioxanone (PDS) suture.
• Data collected included reasons for sternotomy, sternal wound complications, and hospital mortality.

Main Results:

• Sternal wound infection, dehiscence, or mediastinitis occurred in 1.5% of patients (4 of 264).
• The hospital mortality rate associated with mediastinitis was 1.1% (3 of 264) in the early postoperative period.
• The study included diverse pediatric cardiac conditions such as tetralogy of Fallot, VSD, and ASD.

Conclusions:

• Poly-p-dioxanone (PDS) suture is a safe and reliable alternative for sternal closure in pediatric open cardiac surgery.
• The absorbable nature of PDS suture and the employed technique contribute to favorable outcomes.
• This approach offers a viable alternative to standard sternal closure methods, potentially reducing complications.
