At the end of the study, four dogs were alive without signs of recurrence, while one dog died of a suspected pulmonary embolism at 510 days. Median surgical time was 125 minutes (range, 80-210). No significant intraoperative or postoperative complications occurred, and all dogs were discharged 3 to 4 days postoperatively. Kidney preservation was achieved in all dogs. In one dog with an ectopic adrenal tumor located ventral to the left kidney, the thrombus was occluding 90% of caval flow, and a small caval venotomy was required to remove it. Tumor thrombus was removed by renal venotomy in five dogs. Recorded data included signalment, clinical signs and results of laboratory testing, physical examination findings, diagnostic imaging results, surgical technique, surgical time, surgical complications, and outcome. Renal venotomy was performed at the time of adrenalectomy for tumor thrombus removal. Methodsĭogs with adrenal tumors and vascular invasion into the RV and CVC were retrospectively enrolled in this multi-institutional study. Study designįive client-owned dogs that underwent adrenalectomy. To describe the surgical technique and report the outcomes of adrenalectomy and thrombus removal with kidney preservation by renal venotomy in a population of dogs with adrenal tumors and vascular invasion into the renal vein (RV) and caudal vena cava (CVC).
