Experimental study of destruction to porcine spleen in vivo by microwave ablation

Figure 3 The pathological changes after microwave ablation. A: Normal spleen tissue (the arrow indicates the splenic corpuscle), hemotoxylin and eosin (HE) × 20; B-D: The pathological changes immediately after microwave ablation (MWA); B: There was some remaining spleen tissue around arterioles in the areas of coagulation necrosis (↑), HE × 20; C: The ablation borderline was not very clear (↑), HE × 20; D: There were no obvious signs of hydropsia or inflammatory reaction, HE × 40; E-H: Pathological changes 1 wk after MWA; E: The coagulation necrosis was well-distributed and complete, HE × 20; F: The ablation borderline was clearer 1 wk after ablation (↑), HE × 20; G: There were some signs of hydropsia and inflammation (↑), HE × 40; H: Many nuclear fragmentations could be seen clearly (↑), HE × 40.
