Implementation Considerations

• Requires microsurgical expertise in vascular anastomosis and vessel handling.
• Dependent on instrumentation for precise vessel clamping, suturing, and elastase incubation.
• Necessitates cross-team standardization between surgical, histological, and imaging teams for consistent outcomes.
• Involves adaptation considerations when translating the model to other vessel types or species.
• Limited by the technical complexity of pouch preparation and elastase exposure timing, which must be controlled to ensure consistent vessel weakening.
