PSS Flashcards
Joffe
Securing cellophane bands
VetSurg 2019
Medium clips failed less than Medium-large clips at 50% attenuation
3 layer failed more than 4 layer
Mullins
Short term survival for post attenuation seizures
VetSurg 2020
32% survived 30 d
82% experienced generalized seizures
Short term survival is associated with
~hx of pre-op seizures
~development of focal seizures
Otomo
Long term with a thin-film band or Ameroid
VetSurg 2020
Post-op seizures 8%
Strickland
Cats with Congenital PSS
VetSurg 2021
Post attenuation signs 62%
Osmolality low at 24 h post-op in cats with neuro signs
No association with Keppra

Devriendt
Serum momoethylglycylxylidide (MEGX) concert to assess shunt closure
JVIM 2021
MEGX higher in closed than at diagnosis, but not to those with persistent shunting
at T15
Tivers
Intrahepatic congenital PSS with suture attenuation
JSAP 2018
overall PO mortality 13%
First surgery
~18% tolerated complete attenuation
~82% tolerated partial attenuation
Postoperative complications 44%
11% died
Repeat surgery 85%
85% ultimately achieved complete shunt attenuation
3% died
