Evaluation of Complication Rates after Breast Surgery Using Acellular Dermal Matrix: Median Follow-Up of Three Years

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Acellular dermal matrices (ADMs) are widely used in breast reconstruction.
• ADMs are available from human (HADM), porcine (PADM), and bovine (BADM) sources.
• Long-term comparative studies are needed to evaluate complication rates among different ADM types.

Purpose of the Study:

• To compare complication rates and outcomes of HADM, PADM, and BADM in breast reconstruction.
• To evaluate the incidence of Red Breast Syndrome and capsular contracture with different ADMs.

Main Methods:

• Retrospective analysis of 52 ADM-breast reconstructions (oncologic and revision augmentation) from 2010-2015.
• Implantation of 15 HADMs, 21 PADMs, and 16 BADMs.
• Median follow-up of 36 months to assess complications.

Main Results:

• Overall complication rate was 17% (HADM: 7%, PADM: 14%, BADM: 31%).
• Composite endpoint of complications and Red Breast Syndrome showed lower event probability for HADM (7%) and PADM (19%) versus BADM (44%).
• Capsular contracture occurred in 6% of cases.

Conclusions:

• HADM and PADM are recommended for ADM-based breast reconstruction due to lower complication rates.
• BADM exhibited the highest complication probability but offered advantages in flexibility and aesthetics.
• Individual patient assessment is crucial for selecting the appropriate ADM for breast reconstruction.
