Does Sternal Cable System Prevent Sternal Complications after Revision Sternal Surgery?

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Biomedical Engineering

Background:

• Secondary sternal dehiscence is a serious complication after open heart surgery requiring repeat sternal closure.
• Evaluating novel sternal closure materials is crucial for improving patient outcomes and reducing revision rates.

Purpose of the Study:

• To compare the efficacy of a sternal wire system versus conventional steel wires in preventing secondary sternal dehiscence.
• To assess the effectiveness of sternal closure methods in revision surgeries following open heart procedures.

Main Methods:

• A retrospective case-control study involving 389 patients who underwent open heart surgery with median sternotomy.
• Patients were divided into two propensity-matched groups based on sternal closure material: sternal cable system (Group 1) or conventional steel wires (Group 2).
• Data collected included time to sternal reconstruction surgery and various perioperative parameters.

Main Results:

• No significant difference in secondary sternal dehiscence rates was observed between the sternal wire system group and the conventional steel wire group (p = 0.366).
• Group 1 (sternal wire system) showed significantly higher durations of cardiopulmonary bypass and increased use of intra-aortic balloon pumps and extracorporeal membrane oxygenators.
• Group 2 (conventional steel wires) had a significantly higher number of emergency operations.

Conclusions:

• The sternal wire system is not superior to conventional steel wires in preventing secondary sternal dehiscence after revisional open heart surgery.
• Conventional steel wires remain a viable and effective option for sternal closure in revision cases, with no significant difference in dehiscence rates.
