Spleen

Question 1

Fleming
Small vs. Large dogs with hemoperitoneum
VetSurg 2018

Answer 1

Splenic hemorrhage
43% small
61% large

Small dogs Hemorrhage

spleen: Small < Large
liver: Small > Large
another: Small > Large

HSA associated with splenic hemorrhage
Large > Small

cut off 20 kg

Question 2

Story
Small breed dogs splenic HSA
VetSurg 2020

Answer 2

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
~small 446d
~large 80d
*dog size significant

Question 3

Sirochman
Bipolar sealing device in splenectomy
VetSurg 2020

Answer 3

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

Question 4

Schick
HSA prediction model
JVECC 2019

Answer 4

Bodyweight
Total Solids
Plt Count
Thoracic Radiographs

Question 5

Clarke
Utility of liver biopsy in splenectomy
JSAP 2020

Answer 5

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.

Question 6

Corbin
Splenomegaly in small breed
JAVMA 2017

Answer 6

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

Question 7

Phipps
TEG and splenectomy
JAVMA 2020

Answer 7

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

JAVMA 2021

Answer 8

Thrombocytopenia negative associated with
~Progression Free Interval
~Overall ST

Stage 3 HSA negative associated with
~Progression Free Interval
~Overall ST

Question 9

Burgess
Calculator for splenic mass malignancy
JAVMA 2021

Answer 9

~Serum TP
~Presence of > 2 nRBC/100 WBC
~AUS splenic mass diameter
~# liver nodules 0, 1, >2
~Presence of multiple splenic masses
~splenic mass inhomogeneity
~abdoimnal effusion
~mesenteric, omental, peritoneal nodules
