Evaluation of the effects of combined endoscopic variceal ligation and splenectomy with pericardial devascularization on esophageal varices

Figure 1 Alteration in appearance of ultrasound microprobe images. A: Before treatment, enlarged tortuous varices were found inside of the esophageal wall, while many small vessels adjacent to the muscularis externa formed a venous plexus. B: After treatment, anechoic areas inside and outside of the esophageal wall disappeared or remained only tiny, while the echo of mucosa and submucosa of the esophagus enhanced. EV: Varices inside of the esophageal wall; Peri-ECVs: periesophageal collateral veins; Para-ECVs: Paraesophageal collateral veins; M: Esophageal mucosa.
