An 11-year-old, 22 kg, male neutered English Staffordshire Bull Terrier, in which a pheochromocytoma was removed from the left retroperitoneal space, was referred to investigate the regrowth of a mass in the same region. A neuroendocrine tumour, compatible with pheochromocytoma, was cytologically diagnosed after ultrasound-guided fine-needle aspirates, and the dog underwent explorative celiotomy. A combination of thoracic epidural anaesthesia, dexmedetomidine and magnesium sulphate infusion was used intraoperatively to control nociception and potential haemodynamic changes caused by sudden catecholamines release. Postoperative analgesia was provided by administering 0.12% levobupivacaine through the thoracic epidural catheter and oral paracetamol and gabapentin. Postoperative methadone was administered twice during the first 24 postoperative hours only. Two days after the surgery, the dog was anaemic and packed red blood cells were administered. No other complications occurred, and the dog was discharged from the hospital 5 days following surgery. INVESTIGATIONSAbnormalities found on blood analysis are reported in Table 1. Prothrombin time was 6.0 seconds [reference interval (r.i.), 7.0-12.0], activated partial thromboplastin time was 16.0 seconds (r.i., 15.0-25.0). The blood type was dog erythrocyte antigen (DEA) 1.1-negative. In addition to CT findings, an abdominal ultrasound (US) showed nodular hepatopathy, bilateral chronic nephropathy, left mild hydronephrosis. The mass was

“…Successful catheterisation of the RV proximal chamber required multiple attempts and took approximately 10 minutes. Five minutes after catheterization of the RV stenotic passage and the RV distal chamber (30 minutes from starting the surgery), a sudden drop of CI (from 3.5 to 2.1 L/minute/m 2 , reference value 3.6 ± 0.7 L/minute/m 2 ) 9 and mean arterial pressure (MAP; from 65 to 42 mmHg) were observed, together with a decrease of arterial dP/dt max (from 0.5 to 0.29 mmHg/ms; reference value 900–1300 mmHg/s) 10 . Heart rate was 80–95 beats per minute, SpO 2 99% and PE′CO 2 decreased from 51 to 46 mmHg (Table 1).…”

Anaesthetic management and complications during cutting balloon and high‐pressure balloon dilation in a dog with a double‐chambered right ventricle

A 3‐month‐old female Cocker Spaniel was presented for investigation of a V/VI left basilar heart murmur and diagnosed with a double‐chambered right ventricle. Atenolol was prescribed for 3 months before surgical correction of the congenital anomaly, combining cutting balloon and high‐pressure balloon (CB‐HPB) dilation. A few days before the intervention, the dog showed signs of right‐sided congestive heart failure and it was treated with furosemide, benazepril/spironolactone and pleural effusion were drained. During CB‐HPB dilation, cardiac index and systemic arterial blood pressure suddenly decreased on two occasions probably secondary to a dynamic right ventricular outflow tract obstruction. Cardiac arrest occurred and cardiopulmonary resuscitation was unsuccessful.
