ポータブルエコーを用いたPSP皮弁・超薄皮弁の短時間挙上法

　Pure-skin-perforator (PSP) and super-thin (ST) flaps are useful for thin soft tissue reconstruction, but they require meticulous proximal-to-distal perforator dissection for primary thinning using the conventional elevation method. To address this challenge, the subdermal dissection technique has been developed in which a PSP/ST flap is directly elevated via distal-to-proximal dissection without primary thinning. Precise localization of PSPs is key to successful PSP/ST flap elevation and can be conducted using a portable ultrasound device with a 15-18-MHz probe. Using the subdermal dissection technique and preoperative PSP localization, a PSP/ST flap can be elevated within 30 minutes on average. As the device is widely used by internists and general surgeons, the procedures can be applied in any general hospital without buying an expensive ultra-high-frequency ultrasound device.
