Balloon occlusion of the caudal vena cava for vascular contrast studies as an aid to intravascular coil embolisation for the treatment of intrahepatic portosystemic shunts in three dogs

Abstract

Interventional radiological procedures are an emerging area of veterinary medicine and procedural modifications may help expand their use in clinical practice.

In this issue – December 2015

“…The second case report describes the use of a vascular occlusion balloon to give high‐definition contrast venography in three dogs . This was to aid visibility to perform intravascular coil embolisation for treatment of intrahepatic portal systemic shunts.…”

“…Two surgical papers from the same group give detailed descriptions so that their techniques can be reproduced. 3,4 One reports a series of cases to assess the use of a bipolar vessel sealing device (BVSD) to resect the soft palate and perform tonsillectomy in dogs with clinical signs of upper respiratory obstruction related to a brachiocephalic facial structure. 3 A variety of surgical methods have been described to reduce resistance to airflow, to improve oxygen saturation and decrease arterial carbon dioxide levels.…”

“…The second case report describes the use of a vascular occlusion balloon to give high-definition contrast venography in three dogs. 4 This was to aid visibility to perform intravascular coil embolisation for treatment of intrahepatic portal systemic shunts. Interventional radiography techniques are being used increasingly in veterinary medicine and this techniques aims to improve visibility in vascular contrast studies.…”

Percutaneous shunt vessel embolisation with Amplatzer vascular plugs II and IV in the treatment of dogs with splenophrenic shunts: four cases (2019‐2022)

“…To monitor hepatic function, ammonia and bile acids should be measured (Franchi-Abella et al 2010, Bernard et al 2012. In veterinary medicine, intrahepatic portosystemic shunts have been treated with central venous catheter stents and coils (Gonzalo-Orden et al 2000, Asano et al 2003, Bussadori et al 2008, Weisse et al 2014, Cook et al 2015, Knapp et al 2015, Case et al 2018, Culp et al 2018, Johansen et al 2018. On the other hand, catheter treatment for extrahepatic portosystemic shunts has used coils as embolic devices (Léveillé et al 2000, Léveillé et al 2003, Bussadori et al 2008.…”
