Interventricular septal hematoma in ventricular septal defect patch closure

Area of Science:

• Cardiology
• Pediatric Surgery
• Medical Imaging

Background:

• Perimembranous ventricular septal defects (VSDs) are common congenital heart abnormalities.
• Surgical closure is the standard treatment for significant VSDs.
• Postoperative complications, though rare, require prompt recognition and management.

Observation:

• A 4-month-old infant developed an interventricular septal hematoma following patch closure of a perimembranous VSD.
• Postoperative day 1 echocardiography revealed a large intramural hematoma.
• The hematoma caused significant thickening of the ventricular septum.

Findings:

• The interventricular septal hematoma was a voluminous collection of blood within the septum.
• Severe thickening of the ventricular septum was observed due to the hematoma.
• Echocardiography proved crucial for diagnosing this postoperative complication.

Implications:

• Prompt diagnosis and surgical intervention are critical for managing interventricular septal hematomas.
• This case highlights the importance of vigilant postoperative monitoring in pediatric cardiac surgery.
• Understanding rare complications like septal hematomas can improve surgical outcomes for VSD repair.
