"CT can be performed pre-procedure for evaluation of splenic injury, to measure splenic volume, and identify accessory spleens (splenunculi). CT angiography is also useful for characterisation of vascular anatomy including any variants ³."

"The spleen is responsible for important haematological and immunological processes including the production of antibodies, removal of damaged blood cells, and destruction of encapsulated pathogens. Impaired immunity is therefore the major long-term concern following a splenectomy, particularly the risk of overwhelming post-splenectomy infection (OPSI)."

"Overwhelming post-splenectomy infection (OPSI) is a high mortality fulminant process (typically secondary to Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis) that can rapidly progress to coma and death within 24 to 48 hours ⁵. Splenectomy patients are therefore given pneumococcal, meningococcal, and influenza vaccinations pre-procedure. Immunosuppressed patients are further given life-long prophylactic antibiotics ²."

"The first documented splenectomy was performed by K S Quittenbaum in 1826 ². The spleen was long considered a redundant organ until 1952, when the risk of overwhelming post-splenectomy infection (OPSI) was highlighted by H King and H B Schumacher ². Since then, less invasive procedures such as splenic artery embolisation have been advocated as a first-line treatment."
