MST
~small 116d
~large 97d
*metastatic disease decreased survival time
Survival time of surgery and chemo
~small 207d
~large 139d
*administration of chem increased survival time in small breed
DFI

VetSurg 2020
Short term mortality 11%
7% died prior to discharge
3% died prior to suture removal
Prior to discharge associated with
~administartion of blood
~increased duration of anesthesia
~intra-op V-tach
Prior to suture removal associated with
~administration of blood

Utility of liver biopsy in splenectomy
JSAP 2020
Abnormalities noted in
normal-appearing liver 3%
abnormal appearing liver 29%
Haemoabdomen associated with an increased likelihood of liver neoplasia on biopsy at the time of splenectomy.
Corbin
Splenomegaly in small breed
JAVMA 2017
less than 16 kg
~50/50 malignant
HSA 67% of malignancies
WHWT more likely to have neoplasia
Malignancy & Hemoabdomen
= decreased survival time
Malignancy is not associated with hemoperitoneum
Phipps

JAVMA 2020
Thrombocytosis and TEG suggestive of hypercoagulopathy increased from day 2 after surgery until at least 2 weeks PO
