Methods for treating an extravascular hematoma in a patient can include liquefying a first portion of the extravascular hematoma by applying a first series of focused acoustic pulses to the extravascular hematoma at a first frequency; and liquefying a second portion of the extravascular hematoma by applying a second series of focused acoustic pulses to the extravascular hematoma at a second frequency. Liquefied remains of the extravascular hematoma can be aspirated from the patient following liquefaction and disruption.
