“…A ventrolateral-to-dorsomedial dimension greater than 14.6 mm for the left gland and 11.1 mm for the right gland, with asymmetry, heterogeneous contrast enhancement or irregular shape, were considered abnormal. 22,23 The adrenal size and the degree of vascular invasion were recorded.…”

Objective Review medical records of dogs that underwent adrenalectomy without pre‐operative medical management, to examine the peri‐operative morbidity and mortality. Design Case series of 65 dogs. Methods Medical records were reviewed. Features recorded included the histologic diagnosis, intra‐operative hypertension or tachycardia, requirement for cavotomy, administration of intra‐ and post‐operative corticosteroids, performance of additional surgery and the occurrence of peri‐operative complications. Dogs requiring emergency surgery were excluded. Results Of the 65 dogs, 49 had adrenocortical tumours (11 bilateral), 13 had pheochromocytomas (one bilateral) and three dogs had tumours in both adrenal glands of a different tumour type. Five dogs had caudal vena cava invasion and 33 had additional procedures performed at the same time. Mortality occurred in 1/65 dogs (1.5%; 95% CI 0.03%–8.2%), major complications were identified in 1/65 dogs (1.5%; 95% CI 0.03%–8.2%) and minor complications occurred in 10/53 dogs (15%; 95% CI 8.6%–26%). Conclusion Based on the limited peri‐operative complications and low mortality in this pre‐operatively untreated cohort, and based on critique of the available literature, the added value afforded by pre‐operative treatment is questioned. With appropriate management, adrenal tumours can be removed with few peri‐operative complications and low mortality.

“…In veterinary medicine, CT angiography, including dual-phase and triple-phase helical CT, is widely used in clinical and experimental fields [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. In these contrast CT imaging protocols, the timing of the start of scanning was determined based on previously reported TACs [ 13 , 14 , 15 ].…”

“…In veterinary medicine, multiphasic multi-detector computed tomography (CT) angiography, including triple-phase helical CT, is currently used as a diagnostic tool for vascular disorders, such as portosystemic shunts [ 1 ], arteriovenous fistulae [ 2 ], and various tumors [ 3 , 4 , 5 , 6 , 7 , 8 ]. This method is also commonly used for characterizing parenchymal disease, such as pancreatic disease [ 9 , 10 , 11 , 12 ].…”

This prospective crossover study compared the effects of intramuscular administration of medetomidine for sedation on parameters of the abdominal vascular system, measured by enhancement computed tomography (CT), to those of propofol-induced sevoflurane maintenance anesthesia, as a control, in five clinically healthy adult male beagle dogs (11.4–12.8 kg). Each animal underwent both protocols at a 1-week interval. The enhancement (HU) and time to peak enhancement on CT were measured for the aorta (AO), caudal vena cava (CVC), portal vein (PV), and hepatic parenchyma (HP). The contrast effects in the AO, PV, and HP were significantly delayed under medetomidine sedation compared to the control anesthesia protocol. Particularly, the contrast effect in the PV and HP was significantly delayed under sedation, appearing approximately 1 min after contrast medium injection. This delay likely reflects the peripheral vasoconstrictive effect of medetomidine. We noted a generally early high contrast enhancement of the CVC under medetomidine sedation, likely contributed by the induced bradycardia. Therefore, findings obtained on contrast enhancement CT under medetomidine sedation may be different from those obtained under propofol-induced sevoflurane maintenance anesthesia. These differences are important to consider when using the findings to inform diagnosis.
