The evolution of prepectoral breast reconstruction has been driven by the search for techniques that provide both immediate aesthetic results and long-term stability. Recent clinical data, including the 5-year results from Salgarello et al. (2025) and multicentre observations from De Vita et al. (2024), offer a comprehensive look at how material choice and surgical design influence the reconstructive journey.
1. Identifying the Clinical Challenges (Salgarello et al. 2025)
The Salgarello study highlights critical long-term performance markers for Polyurethane (PU)-coated implants and porcine Acellular Dermal Matrix (ADM) full-wrap techniques:
- Capsular Contracture: At 5 years, severe contracture (Baker 3-4) reached 47.7% in the porcine ADM group and 24.3% in the PU group.
- Surgical Burden: Total secondary procedure rates were significant (65.1% for ADM; 38.9% for PU), indicating a high long-term management requirement.
2. Contextualizing the Bovine Pericardium Profile (De Vita et al. 2024)
When viewed alongside these findings, the data for ExaShape® (Bovine Pericardium) suggests a different clinical trajectory. This is attributed to two primary factors:
- Material Origin: Bovine pericardium features a bi-layer, microporous structure that facilitates rapid, integrated neovascularization. This supports high-quality tissue remodeling without the excessive fibrotic response often associated with dermal-derived matrices.
- Mechanical Design: The anterior-pocket technique avoids the 360° restrictive wrap, reducing tension on the skin flap—a known trigger for capsule development.
3. Side-by-Side Data Highlights
Conclusion and Clinical Insights
While the studies discussed evaluate different patient cohorts, materials, and follow-up periods, we believe it is essential to share these comparative insights. Understanding that outcomes in prepectoral reconstruction are highly dependent on the specific synergy of material and technique allows for more tailored clinical decisions.
Our objective is to highlight that the challenges observed with certain traditional models – specifically high rates of late-onset fibrosis and revision surgery- do not necessarily concern the bovine pericardium anterior-pocket approach. By utilizing a material designed for biological integration and a technique that respects tissue tension, clinicians can achieve a stable clinical course with a low incidence of late-onset complications, potentially reducing the long-term surgical burden for the patient.
