William Levy

William's sign is one of the chest examination items. There are three cases: 1 When the pleural effusion is in the chest, the patient takes the seat, and the examiner looks at the chest from the top down with the same force and compares it on both sides. If the second intercostal space on the affected side is a high-pitched voice, the lower part is a turbid drum sound, and then the lower part is a real sound. 2 In the early stage of apical tuberculosis, when the ipsilateral diaphragm is inhaling, the movement is weakened; the method is the same as the Liteng phenomenon. 3 In chronic adhesive pericarditis, the paralyzed patient takes the supine position. The examiner opens the fingers five fingers slightly, the right hand is placed flat in the front of the heart, and the left hand is placed flat on the right chest. The two hands meet on the midline. Let the patient take a deep breath and observe the extent of the hands raised. When normal, both hands are raised and lowered with the breath, and the amplitude is equal. If the hand placed in the anterior region of the heart is found, the patient's respiratory elevation is lower than the right side, which is the sign. This sign is caused by the pericardium and pleura, resulting in the adhesion of the lungs resulting in limited left lung expansion.
