Abstract: | The radiographic and ultrasonographic signs in eight dogs with a surgical or pathologic diagnosis of retained surgical sponge were reviewed. The most frequent previous surgery was ovariohysterectomy, either as an elective procedure or to treat pyometra. The median elapsed time between surgery and diagnosis of retained surgical sponge was 9.5 months (range 4 days to 38 months). Five dogs had a draining sinus; four had a palpable abdominal mass. Radiologic signs included localized, speckled or whirl-like gas lucency, abdominal mass, and non-focal soft tissue swelling. Survey radiography and sinography were considered diagnostic for retained surgical sponge in 4/7 (57%) and 3/5 (60%) dogs, respectively. The combined use of survey radiography and sinography enabled detection of 6/7 (86%) sponges. In each dog that had ultrasonography, a hypoechoic mass was found that had an irregular hyperechoic centre. The possibility of retained surgical sponge should be considered in animals with a history of previous surgery and a sinus or abdominal mass. |
