Spool-like stent for the open sternum after cardiac operations
The Annals of Thoracic Surgery
|February 1, 1997
Insights
Delayed sternal closure using a novel spool-like stent can manage severely edematous hearts after cardiac surgery. This technique maintains cardiac space and stabilizes the chest wall for effective patient management.
Area of Science:
- Cardiothoracic Surgery
- Biomedical Engineering
- Postoperative Care
Background:
- Post-cardiac surgery, severe myocardial edema can lead to sternal compression, complicating treatment.
- Conventional sternal closure is contraindicated when the heart remains significantly enlarged due to edema.
- Delayed sternal closure offers a potential solution by allowing the heart to reduce in size.
Purpose of the Study:
- To introduce a novel spool-like stent designed for delayed sternal closure in cardiac surgery patients.
- To evaluate the stent's efficacy in maintaining adequate cardiac space and chest wall stability.
- To facilitate management of patients with a severely edematous heart requiring open sternum procedures.
Main Methods:
- Development of a custom spool-like stent to bridge an open sternotomy.
- Application of the stent to maintain thoracic volume and cardiac dimensions.
- Assessment of chest wall fixation and patient management strategies with the sternum open.
Main Results:
- The spool-like stent successfully maintained optimal space for the edematous heart.
- The stent provided stable fixation of the chest wall, enabling necessary interventions.
- This approach addressed the challenge of managing cardiac compression post-operation.
Conclusions:
- Delayed sternal closure with a spool-like stent is a viable and effective strategy for managing severe myocardial edema after cardiac operations.
- The device facilitates critical postoperative care by preventing sternal compression and ensuring chest wall integrity.
- This innovative technique improves outcomes for patients with compromised cardiac dimensions following surgery.
Abstract:
Severe edematous heart after a cardiac operation is impossible to treat if there is compression of the heart due to the sternum. In these patients delayed sternal closure may be a useful procedure until the heart decreases in size. We devised a spool-like stent for the open sternum to maintain the optimal cardiac space for the severely edematous heart and to fix the chest wall to allow for management while the sternum is open.
