Adrenal Flashcards
Mayhew, Vet Surg, 2018:
Phrenicoabdominal venotomy for tumor thrombectomy
What % of dogs required extension of the phrenicoabdominal venotomy into a cavotomy due to fragmentation of the thrombus during removal?
Intra-op complication rate?
Post-op mortality rate?
What is the key to using this technique?
Mayhew, Vet Surg, 2018:
13% required extension of the phrenicoabdominal venotomy into a cavotomy due to fragmentation of the thrombus during removal
Intra-op complication rate: 13%
Post-op mortality rate: 25%
The key to using this technique is the presence of a modestly sized thrombus whose maximal width does not greatly exceed the width of the phrenicoabdominal vein at its entry point into the vena cava
Mayhew, Vet Surg, 2019:
Per-op morbidity and mortality associated with adrenalectomy and cavotomy
Distribution of tumor types?
What % of the thrombi terminated caudal to the diaphragm and what % terminated cranial to the diaphragm?
Mortality rate?
What was associated with a greater risk of death?
Mayhew, Vet Surg, 2019:
80% pheochromocytomas, 16% adrenocortical carcinomas, 4% unknown type
80% of thrombi terminated caudal to the diaphragm, and 11% terminated cranial to the diaphragm (remaining 9% were unknown)
Mortality rate: 24%
Termination of the thrombus cranial to the diaphragm was associated with a greater risk of death, but not tumor type or size
Knight, Vet Surg, 2019:
Variations in surgical technique for adrenalectomy and cavotomy
Mortality rate?
Effect of extension of caval thrombus beyond the hepatic hilus on outcome?
Knight, Vet Surg, 2019:
Mortality rate: 21%
No effect of extension of caval thrombus beyond the hepatic hilus on outcome
Knight
Adrenalectomy with caudal vena cava venotoy
VetSurg 2019
Peri-op mortality 21%
Knight et al VetSurg 2019
What is the preoperative mortality rate for dogs undergoing caudal vena cava venotomy + adrenalectomy?
21%
Extension of thrombus beyond hepatic hilus did not preclude a good outcome
