Trombose pós cirúrgica em veia cava caudal em um cão com hipercortisolismo adrenal-dependente

Abstract

Hyperadrenocorticism (HC) is a common endocrinopathy in dogs, characterized by excessive glucocorticoid production and associated with various clinical and systemic manifestations, including hemostatic alterations. A frequent but often underdiagnosed complication is thromboembolism in the arterial or venous system. This report describes a case of thrombosis in the caudal vena cava of a 12 year-old female Poodle diagnosed with adrenal-dependent hyperadrenocorticism at the Veterinary Hospital of UFPB. The diagnosis was based on laboratory tests, ultrasonography, and a low-dose dexamethasone suppression test. Treatment was initiated with Trilostane, along with surgical correction of pre-existing mammary nodules through nodulectomy and therapeutic ovariohysterectomy. In the postoperative period, a thrombus was detected in the caudal vena cava, necessitating the introduction of antiplatelet therapy with clopidogrel and anticoagulation with rivaroxaban. This case highlights the complexity of HC, the need for continuous monitoring, and the importance of an individualized management approach to prevent and treat associated complications.
