- 2What condition in large dogs can cause the short gastric vessels of the spleen to rupture and the spleen to necrose?GDV
- 3How would you do a fast total splenectomy?Ligate at the 5 main sites
- 4Which vessels would you ligate in a partial splenectomy?Hilar vessels at line of demarcation
- 5What suture pattern would you use to close in a partial splenectomy?Two rows of continuous overlapping mattress sutures and close the cut end with continuous suture

-You can do a splenectomy but the median survival is less than 4 months
-Splenectomy + chemo will give you 6 month survival - 11How does a splenic torsion occur and what does it occlude?hilar vessels because the spleen twists on its vascular pedicle
- 12What is the most useful way to diagnose a splenic torsion?Ultrasound
- 13What are the clinical signs of acute splenic torsion?1. Abdominal pain, distension, shock
