From 80mm to 20mm: How Fuwai Hospital’s Expert Team Redefines the Gold Standard for Minimally Invasive VSD Repair
🩺 [Clinical Profiling] Patient: 2-year-old female. Diagnosis: CHD, Perimembranous VSD.
Clinical Challenge: Critical stage of thoracic development. The primary concern is avoiding sternal non-union, pectus carinatum, and permanent scarring associated with a traditional 80-100mm median sternotomy.
Anatomical Data: Defect diameter 6-8mm with mild pulmonary hypertension.
⚖️ [Decision Logic & Clinical Dilemma] The Fuwai Hospital Expert Team analyzed two standard approaches:
Median Sternotomy: Optimal exposure but involves irreversible disruption of mediastinal stability via sternal splitting.
Modified Axillary Mini-Incision: High technical threshold; visibility limited to a 20mm gap. Requires precision cannulation within a restricted radius.
Final Decision: Based on a volume of 1,000+ pediatric minimally invasive cases, the team performed the "Modified Right Axillary Mini-Incision VSD Repair."
🛠️ [Key Technical Workflow]
Incision: A 20mm incision along natural skin folds (4th intercostal space, mid-axillary line).
Dissection: Blunt dissection of the serratus anterior to preserve the long thoracic nerve; established a 30mm operative tunnel.
CPB: Cardiopulmonary bypass initiated via ascending aorta and vena cava cannulation within the mini-incision.
Repair: VSD sutured with 5-0 Prolene. Suture depth was strictly controlled to protect the Bundle of His, preventing postoperative heart block.
✨ [Professional Synthesis] This case demonstrates the successful integration of Anatomical Precision and Aesthetic Recovery. By confining trauma to natural axillary creases and eliminating sternal wire fixation, the Fuwai team minimized pulmonary complications and shortened recovery time.
