US-PSB is performed bilaterally by two separate injections of local anesthetic at level of the second and fourth intercostal space into the interfascial plane between major pectoralis and intercostal muscles. PMM: Pectoralis major muscle; IIM: intercostal muscle; EIM: external intercostal muscle; TTM: transversus thoracis muscle; LA: local anesthetic; N: needle; Pl: pleura; Rib: rib
