An endoscopic follow-up study of the development of diffuse antral vascular ectasia.
No endoscopic follow-up studies are available on the development of diffuse antral vascular ectasia (DAVE). We present here a ten-year follow-up study from discrete initial lesions to the full picture of DAVE. In a 72-year-old female patient with liver cirrhosis, the earliest findings of DAVE were several red spots, with or without a white halo, in the distal antrum. During follow-up, the spots increased in number, coalesced, and extended to the proximal antrum. Three years after the initial findings, latent hemorrhage occurred at a time when confluent lesions were formed. One year later, diffuse distribution of the antral lesions was observed, which led to the diagnosis of DAVE and developed to the full picture within three more years. Two years later, the patient presented with hematemesis, which confirmed the diagnosis of DAVE clinically. Treatment consisted of monopolar electrocoagulation, leading to a stable hemoglobin value for one year. This case study provides some substantial clues to the early detection and treatment of DAVE.
