Intraoperative Identification of Perforator Spasm and Decreased Pulsation Using Video-capillaroscopy during Free Flap Harvest.

ABSTRACT: Temporary or prolonged vascular spasm can be appreciated when perivascular dissection is performed for microvascular reconstruction. Due to a lack of reliable assessment modalities, the resolution of spasm at the periphery of perforators cannot be determined by naked eyes or surgical loupes. To address this conundrum, we aimed to observe the state of perforator vessel spasm after flap elevation using video-capillaroscopy. Between November 2021 and February 2022, seven free flaps were evaluated with video-capillaroscopy to determine the incidence of vasospasm in less than 1 mm-diameter perforators. The type of perforator spasm after flap elevation was divided into six types according to the video-capillaroscopy findings: type A, no spasm/decreased pulsation (S/DP); type B, S/DP with recover
