In this episode of How I Operate, Ryan Sugrue is joined by Professor Claudio Angrigiani, the creator of the Posterior Interosseous Artery (PIA) flap and one of the pioneers of perforator flap surgery.
Looking back over four decades of innovation, Professor Angrigiani shares the story behind the development of the PIA flap, from cadaveric anatomy studies in Argentina to its adoption as a reliable reconstructive option for hand and wrist defects around the world. Along the way, he explores the importance of anatomy, surgical simplicity, and why understanding vascular territories remains fundamental to flap design today.
Key Takeaways:
- How the PIA flap was developed as an alternative to traditional reconstructive options for the hand.
- The role of anatomical research and cadaveric studies in creating dependable surgical techniques.
- Why the middle perforators are key to the reliability of the PIA flap.
- Common technical mistakes that can lead to complications or flap failure.
- The importance of simplifying flap surgery through a deep understanding of anatomy.
- Professor Angrigiani's approach to innovation, research, and developing new surgical techniques.
