Abstract

In head and neck oncologic surgery a reconstructive phase is often required and pedicled flaps are still a viable option, though they may need a pedicle division performed at a later stage. Several techniques are commonly used for perfusion assessment of the flaps, with indocyanine green (ICG) fluorescence video-angiography representing a promising tool. We used ICG video-angiography to evaluate the perfusion of two of the most commonly adopted pedicled flaps in the head and neck field (the supraclavicular and the paramedian forehead flap) before and after second-stage pedicle division, allowing a safer in-setting. Moreover, the new high-resolution device that we have employed added further accuracy to the traditional video-angiography, providing a real-time flap-to-normal skin ICG ratio. Indeed, ICG video-angiography proved to be a useful tool in head and neck reconstructive surgery and it may allow an earlier second-stage pedicle division.

Why This Matters for Hirudotherapy

This study used indocyanine green (ICG) fluorescence video-angiography, with a new high-resolution device providing a real-time flap-to-normal-skin ICG ratio, to assess perfusion of two commonly used pedicled flaps (supraclavicular and paramedian forehead) before and after second-stage pedicle division in head and neck reconstruction; the authors report that ICG video-angiography proved a useful tool that may allow earlier, safer pedicle division. Its relevance to hirudotherapy is as context on perfusion assessment in reconstructive surgery, the domain where leech therapy is used adjunctively for venous congestion, since objective perfusion data informs decisions about flap viability. Honest caveats: this is a small technique-focused clinical report on a specific imaging device and flap types, not a comparative trial, and it does not involve or evaluate medicinal-leech treatment.
