sternal dehiscence
Separation or breakdown of sternal closure following median sternotomy, requiring surgical revision.
Full Definition
Sternal dehiscence is a serious postoperative complication characterized by separation or breakdown of the sternal closure following median sternotomy. This condition can range from superficial wound separation to complete sternal instability with mediastinal exposure. Risk factors include obesity, diabetes, chronic obstructive pulmonary disease, prolonged mechanical ventilation, and infection. Management typically requires urgent surgical revision with re-closure, often involving additional fixation techniques such as sternal bands, plates, or muscle flaps. Prevention strategies include proper sternal closure technique and optimization of patient risk factors.
Usage
Usage note: May be graded as superficial, partial, or complete dehiscence in documentation.
