Background: In dogs pheochromocytoma usually compress and invade into the adjacent vessels and structures, whichmay lead to the occurrence of caudal vena caval tumor thrombi. The surgical approach in these cases requires adrenalectomy with caval thrombectomy. Conventionally, tourniquets and partial occlusion clamp are used to reduce intraoperativeblood loss, but in dogs with a large thrombus associated to a great local tumor invasion, the traditional technique may behindered. The aim of this study was to report the use of a purse-string suture during venotomy of the caudal vena cava forthrombectomy, as an alternative to tourniquet and partial occlusion clamp.Case: An 11-year-old male Daschound breed dog, was referred for evaluation because of the appearance of small blackenednodules in the ventral abdomen. During a search for metastatic lesions with abdominal ultrasound, the right adrenal wasidentified with significant volume increase, and presence of tumor-associate circular formation that appeared to invade thecaudal vena cava, suggestive of neoplastic invasion or thrombus. Abdominal computed tomography showed caudal venacava in its hepatic portion presenting considerable increase in diameter, with caudal dilation and presence of hypoattenuatingmaterial in its lumen. Right adrenal gland with rounded appearance and regular borders, heterogeneous parenchyma andjuxtaposed caudal vena cava suggesting invasion of this, confirming the sonographic findings. During exploratory celiotomy,adherence of the adrenal mass to the right renal vessels and invasion of the caudal vena cava were observed, leading to theneed of nephrectomy and venotomy for thrombectomy. To perform the venotomy, a Rumel tourniquet was placed looselyaround the vena cava only caudal to the invasion point of the tumor thrombus, cranially, tourniquet application was notpossible due to the presence of a large thrombus extending into the intrahepatic cava...

Foi atendida uma fêmea, canina, de raça Chow Chow, com oitos anos de idade com histórico de anorexia há dois dias. Apresentou ao exame físico pelo opaco, foi solicitado hemograma que apresentou anemia,hiperproteinemia e eosinofilia, foi realizado exame bioquímico ALT, FA, ureia e creatinina que não obtiveram alterações.Na ultrassonografia abdominal encontrou-se adenomegalia por hiperadrenocorticismo devido a neoplasia em glândula adrenal direita. Sendo indicado como tratamento adrenalectomia unilateral direita, no exame histopatológico foi caracterizado o Feocromocitoma maligno. O feocromocitoma maligno é um tumor característico de glândula adrenal, ocorre normalmente de forma unilateral. Os tumores adrenocorticais são responsáveis por 15 a 20% do hiperadrenocorticismo (HAC) espontâneo em cães, sendo mais comuns os adenomas e os carcinomas.(AU)
An eight-year-old female, canine Chow Chow breed with an anorexia history of two days old was seen.He was submitted to a physical examination for the opaque, he was asked for a blood count that presented anemia,hyperproteinemia and eosinophilia, a biochemical ALT, AF, urea and creatinine test were performed, which did not change. In abdominal ultrasonography adenomegaly was observed due to hyperadrenocorticism due to neoplasia in the right adrenal gland. Being indicated as a right unilateral adrenalectomy treatment, histopathological examination characterized the malignant pheochromocytoma.Malignant pheochromocytoma is a tumor characteristic of the adrenal gland, usually occurs unilaterally. Adrenocortical tumors account for 15 to 20% of spontaneous hyperadrenocorticism (HAC) in dogs, with adenomas and carcinomas being more common.(AU)
