Figure 6. Photomicrographs of lung sections 1 hour after 35% hepatic cryoablation with immediate resection of the ablated segment (A) or after a 15-minute thawing interval before resection of the cryoablated segment (B). Immediate resection prevented the inflammatory infiltrate (A), whereas delayed resection (B) was associated with infiltration of lymphocytes, neutrophils, and macrophages (arrows) as in cryoablated but nonresected animals.
