The spleen is closely associated with the greater curvature of the stomach and, as a result, splenic torsion is common in dogs with GDV. Once repositioned, the spleen should be assessed for compromise of its vascular supply, specifically avulsion or obvious thrombi. If thrombi are present, the vessels should be ligated, and the spleen removed to prevent the release of thrombi into the circulation. Otherwise, the spleen should be allowed 5–10 minutes to reperfuse following untwisting prior to further assessment. Black areas of the spleen indicate infarction and a partial or complete splenectomy should be performed. In practice, a total splenectomy is preferred as it is technically easier to perform. If the spleen has undergone a complete torsion (i.e., twisted around its pedicle) or is obviously non‐viable, it is preferable to perform a splenectomy prior to untwisting to prevent the release of thrombi and myocardial depressant factors. This may not be possible until the stomach has been repositioned. Studies suggest that splenectomy is required in 10.2–22.6% of dogs treated for GDV [7, 9, 12, 13, 23, 52]. Splenectomy has been identified as a risk factor for mortality, particularly when associated with gastric resection [7, 9, 12, 52].
