Thoracic duct sealing using a bipolar vessel-sealing device in cats
What % of cats had reestablished chylous flow through the previously sealed thoracic duct at 3 months post-op, and how?
Mitchell, Vet Surg, 2018:
83% of cats had reestablished chylous flow through the previously sealed thoracic duct at 3 months post-op through recanalization rather than development of de novo lymphatic vessels

Mayhew, Vet Surg, 2019:
- All cats tolerated thoracic insufflation with 3mmHg and 5mmHg for 30mins without oxygen desaturation, but ventilatory levels had to be increased substantially to maintain eucapnia and oxygenation
- Cardiac index was not affected by thoracic insufflation at 3mmHg but was lower at 5mmHg
- Working space was not different between 3mmHg and 5mmHg of thoracic insufflation
