The conversation then moves into the practical details of microsurgery: intramuscular dissection, perforator selection, venous anastomosis, vessel geometry and the sequence of repair in digital replantation. Along the way, he challenges established dogma, explains the small technical habits he believes improve patency, and shares why de-airing an arterial anastomosis may be critical to avoiding unexplained flap failure.\nKey Takeaways\nWhen the MSAP flap is a useful regional free flap and why Cavadas does not consider it a universal workhorse.\nHow high-setting, non-stick bipolar dissection can make intramuscular perforator dissection faster and more controlled.\nWhy Cavadas usually wants a single perforator and believes one perfect venous anastomosis can be better than two suboptimal ones.\nThe microsurgical habits he uses to protect the endothelium, optimise vessel geometry, and improve anastomotic reliability.\nHow changing the sequence of repair can make digital replantation faster, cleaner, and more reproducible under tourniquet.\nWhy air bubbles in an arterial anastomosis may contribute to apparent “no-reflow” and unexplained flap failure.\nChapters\n\n00:00 – Reconstructing the “Impossible”\n01:50 – The Rise of Perforator Flaps and the MSAP Flap\n04:15 – What the MSAP Flap Is Really Good For\n08:40 – Choosing the Right Flap for Complex Limb Reconstruction\n10:20 – Raising the MSAP Flap and Intramuscular Dissection\n16:30 – Flap Design, Doppler...","thumbnail_url":"https://img.transistorcdn.com/XyWIgVCUN64kycKFaA0kNM1qn-hPt4aj2h72yWRjBY0/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS81NWY3/ZDYxNmIwNWJkMjhi/ZjdiYTc2ZDMzMmY1/Y2YxZC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
