Thoracoscopy

Question 1

Barbur, Vet Surg, 2018:
% of epicardial surface exposed with the novel thoracoscopic pericardiectomy technique vs a standard pericardial window technique?

Answer 1

Barbur, Vet Surg, 2018:
% epicardial surface exposed was increased with the novel thoracoscopic pericardiectomy technique compared to a standard pericardial window technique

Question 2

Steffey and Mayhew, Vet Surg, 2018:
Direct near-infrared fluorescent lymphography (NIRFL) for thoracic duct identification in chylothorax
What % of cases achieved successful NIRFL within 10mins of popliteal lymph node injection?
NIRFL identified small lymphatics that were not visible on CT lymphography in what % of cases?

Answer 2

Steffey and Mayhew, Vet Surg, 2018:
64% of cases achieved successful NIRFL within 10mins of popliteal lymph node injection
NIRFL identified small lymphatics that were not visible on CT lymphography in 8% of cases

Question 3

Mitchell, Vet Surg, 2018:
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?

Answer 3

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

Question 4

Mayhew, Vet Surg, 2019:
Thoracic insufflation in cats
Effect of thoracic insufflation with 3mmHg and 5mmHg for 30mins on oxygen delivery and ventilation?
Effect of thoracic insufflation on cardiac index after 30mins at 3mmHg vs 5mmHg?
Working space achieved with 3mmHg vs 5mmHg of thoracic insufflation?

Answer 4

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

Question 5

Mayhew, Vet Surg, 2019:
Thoracic duct ligation and pericardiectomy for chylothorax
Conversion rate to open approach for thoracic duct ligation?
Conversion rate to open approach for pericardiectomy?
Mortality rate?
Pleural effusion resolved in what % of dogs that survived?
What % of dogs developed late recurrence of pleural effusion 12-19 months post-op?

Answer 5

Mayhew, Vet Surg, 2019:
3% conversion rate for thoracic duct ligation
11% conversion rate for pericardiectomy
Mortality rate: 10%
Pleural effusion resolved in 95% of dogs that survived
9% developed late recurrence of pleural effusion 12-19 months post-op

Question 6

Singh, Vet Surg, 2019:
Optimization of surgical approach
Thoracoscopic-assisted lung lobectomy performed at the left or right 4th or 5th intercostal spaces resulted in a shorter median distance from the stapler anvil to the pulmonary hilus of which lung lobes?
Thoracoscopic-assisted lung lobectomy performed at which intercostal spaces resulted in a shorter median distance from the stapler anvil to the pulmonary hilus of the right caudal and accessory lung lobes?

Answer 6

Singh, Vet Surg, 2019:
Thoracoscopic-assisted lung lobectomy performed at the left or right 4th or 5th intercostal spaces resulted in a shorter median distance from the stapler anvil to the pulmonary hilus of the left cranial and caudal lung lobes and the right cranial and middle lung lobes
Thoracoscopic-assisted lung lobectomy performed at the right 5th or 6th intercostal spaces resulted in a shorter median distance from the stapler anvil to the pulmonary hilus of the right caudal and accessory lung lobes

Question 7

Carvajal, Vet Surg, 2019:
Pericardiectomy and pericardioscopy for idiopathic pericardial effusion
MST for dogs without evidence of masses, nodules and/or adhesion vs dogs with abnormalities identified during pericardioscopy?
MST was not different between dogs with a histopathologic diagnosis of neoplasia and dogs with a histopathologic diagnosis of pericarditis - true or false?

Answer 7

Carvajal, Vet Surg, 2019:
MST: not reached for dogs without evidence of masses, nodules and/or adhesion vs 66 days for dogs with abnormalities identified during pericardioscopy
True
