Radiological examination of gastric “gravel sign” was retrospectively conducted in 60 dogs presented with acute gastric dilatation-volvulus (GDV) syndrome. Other radiographic findings including loss of peritoneal serosal detail, presence of radiopaque foreign bodies, gastric pneumatosis, splenomegaly, and megaesophagus, were also examined in these patients. “Gravel sign” was detected on the pre-operative radiographs of 17 dogs with acute GDV (28.3%), suggesting that these patients could be suffering from chronic partial gastric obstruction before examination. German Shepherd dogs were significantly over-represented in this group (10/17, 58.8%). Dogs with acute GDV showing “gravel sign” should be carefully investigated for the presence of underlying gastrointestinal processes that might be associated with chronic partial obstruction.
