“…Studies in humans have shown that in appropriately selected cases, laparscopic adrenalectomy is an effective tool for controlling PHA 29. It is unknown whether this procedure affected the median survival rate in our patients, but this patient did undergo complete resection of the left adrenal gland and median survival time was approximately 44 months 24. The use of laparoscopic adrenalectomy is based on surgeon experience and appropriate selection of cases such as cats without intravascular invasion and metastatic disease 24…”

“…In cats, most cases of PHA are attributed to unilateral adrenal adenomas or carcinomas 19. There are only a few reports of unilateral adrenalectomies in cats, and perioperative complications of hemorrhage and death were reported in 8 of 18 surgical cases,11, 12, 16, 17, 19, 22, 23, 24 with 6 of those reported as fatalities.…”

BackgroundPrimary hyperaldosteronism (PHA) in cats occurs as a consequence of excessive hormone production by an adrenocortical tumor. Median survival time, association between tumor type and prognosis, and the likelihood that cats require continued medical therapy after surgery have not been systematically evaluated.ObjectivesTo determine the median survival time of cats with PHA treated by unilateral adrenalectomy. To examine if tumor type, anesthesia time, or tumor location (left or right side) affect survival and if affected cats require continued postoperative treatment for persistent hypertension or hypokalemia.AnimalsTen client‐owned cats.MethodsRetrospective study. Cats were diagnosed with PHA based on clinical signs, increased plasma aldosterone concentration, and advanced imaging. Cats underwent unilateral adrenalectomy. Survival time (days alive after surgery) was determined for each cat. Factors affecting median survival time were investigated, including histopathology, anesthesia time, and location (side) of the tumor.ResultsEight of 10 cats survived to discharge from the hospital post adrenalectomy. Overall median survival was 1,297 days (range 2–1,582 days). The only significant factor affecting median survival time was anesthesia time >4 hours. Tumor type and location (side) did not significantly affect median survival time. No cats required continued medical treatment for PHA.Conclusions and Clinical ImportanceAlthough PHA in cats is still considered an uncommon condition, it should be considered in middle to older aged cats with hypokalemic polymyopathy and systemic hypertension. Surgical correction by unilateral adrenalectomy is a viable approach to definitive treatment of PHA with no need for continued medical management.

“…Surgical techniques for adrenalectomies in dogs are increasingly reported (Kyles et al, 2003;Jiménez Peláez et al, 2008;Lang et al, 2011;Massari et al, 2011;Gójska-zygner et al, 2012;Smith et al, 2012;Barrera et al, 2013;Naan et al, 2013).

Adrenalectomies in dogs are being more commonly performed, however anaesthetic management of such cases can be challenging due to the multiple aetiologies of adrenal tumours and the physiological role of adrenal glands. This case report describes the anaesthetic management of a dog with clinical signs of hyperadrenocorticism that underwent unilateral adrenalectomy via laparotomy and discusses anaesthetic preparedness, protocol selection and management of complications for dogs undergoing adrenalectomy.
