a IR-pFV by US after PTPE. In the CH group, the IR-pFV continued to increase through day 1 until day 3. After day 3, the IR-pFV generally remained unchanged until day 7. The IR-pFV generally remained unchanged after day 1 in the MH group. *P < 0.01. b Correlation between the IR-pFV at the non-embolized lobe by US on day 3 and the IR-RLV. The correlation coefficient was 0.7542
