Fig. 1

For the TTP-PECS blocks, the position of the ultrasound transducer is shown in the upper left of the images. During ultrasound scanning of PECS I block, a local anesthetic was injected in the plane between the PMM and Pmm (A); in PECS II block, a local anesthetic was injected in the plane between the Pmm and SM (B); and in TTP block, a local anesthetic was injected in the plane between the IIM and TTM (C). The arrow indicates the injection point. A, artery; PMM, pectoralis major muscle; Pmm, pectoralis minor muscle; SAM, serratus anterior muscle; IIM, internal intercostal muscle; TTM, transversus thoracic muscle
