“…In our case, right pneumonectomy was well tolerated, as 7 months after surgery, the dog experienced only mild exercise intolerance. Good outcomes after right pneumonectomy have already been reported in clinical reports 21,22 . The tolerance of right pneumonectomy in client‐owned animals compared to reports in healthy research dogs may be because these animals had significant disease in the affected lung, leading to a period of accommodation and compensation.…”

A 7‐year‐old female bearded collie was presented with a 6‐month history of coughing. A thoracic and abdominal computed tomography examination revealed a large soft tissue mass within the right caudal and middle pulmonary lobes. A right caudal, middle and accessory lobe lung lobectomy was performed with a combination of manual sutures and staples. A persistent pneumothorax was observed during the 4 days following surgery, and surgical exploration was conducted. Two lung perforations in the cranial pulmonary lobe induced by the suture ends from the first procedure were detected. A right cranial lobectomy using a TA stapler was performed, resulting in a right total pneumonectomy. Seven months after the surgery, the dog was reported to be doing well with no recurrence of clinical signs. To the authors’ knowledge, this is the first case report of a lung perforation caused by suture ends as a complication of lung lobectomy in a dog.

“…[11][12][13][14] However, it appears from previous reports of pneumonectomies in veterinary medicine that this arrhythmia develops infrequently in canine and feline patients, with only two small canine studies identifying AF as a possible complication after pneumonectomy. [15][16][17][18][19][20] One of these studies suggests that the incidence of AF in dogs following pneumonectomy is related to patients' age. 18 The originality of the current report lies in the sudden intraoperative, rather than postoperative, onset of AF and its rapid spontaneous conversion back to SR in less than 5 hours.…”

An 8-year and 2-month-old 37.2 kg crossbreed dog was presented with a persistent cough. Thoracic computed tomography was performed and identified a large lobar mass sitting within the left main stem bronchus. The mass was deemed operable, but considering the unique technical challenges associated with the surgery (need for specific ventilation strategies and risk of major haemorrhage) a guarded prognosis was given. A total left-sided pneumonectomy via a lateral thoracotomy was performed. One-lung ventilation was required in order to allow surgical access. During the surgery, the dog suddenly developed atrial fibrillation, which converted back to a normal sinus rhythm (SR) during the recovery period. The dog recovered uneventfully following the return to SR and was discharged 72 hours after the surgery. Histopathological results of the lung mass concluded to a primary pulmonary chondrosarcoma.

“…However, right pneumonectomy has been reported in dogs and cats and shows that survival is possible in cases where chronic disease allows adaptation prior to pneumonectomy. 11,12 Surgical treatment for pulmonary laceration involves closing the site with a mattress pattern of absorbable suture or partial lung lobectomy. 13 In this case, a lung lobectomy was not performed, as it would have involved excising the only major lobe with adequate ventilation.…”

Case summaryA 2-year-old female neutered domestic shorthair cat was presented for investigation of acute onset tachypnoea and dyspnoea. Pyothorax was diagnosed based on thoracic radiographs and fluid analysis. Medical treatment consisted of bilateral thoracostomy tube placement, antibiotic therapy and thoracic lavage. After 12 days of medical management infection was still present, warranting exploratory thoracotomy. At surgery, encapsulated abscesses were found in the left lung, right cranial and right middle lobes. The right caudal lobe was the only macroscopically non-abscessated lobe, and appeared to have a parenchymal laceration 8 mm long over the dorsolateral surface. Following partial pericardiectomy, mediastinectomy and debridement of abscesses, a pericardial flap was reflected caudolaterally and apposed over the laceration to seal the affected lung lobe. This flap was sutured to a rim of fibrinous adhesion that was partially covering this lobe. After 8 days the cat was discharged with antibiotic therapy for 3 more weeks. Follow-up assessment at 19 and 38 weeks postoperatively confirmed the cat to have good exercise tolerance. Thoracic radiographs at 19 weeks revealed good bilateral aeration of the pulmonary parenchyma without pleural effusion.Relevance and novel informationLung lobe laceration can be treated by lung lobectomy or direct suturing of the lung parenchyma. This is the first report using a pericardial flap to repair a lung laceration. Pericardial flap was successfully used to treat this lung laceration where lobectomy was contraindicated. Encouraging results were present at 8 months postoperatively.

Postoperative Respiratory Function and Survival After Pneumonectomy in Dogs and Cats

Abstract: Dogs and cats have acceptable respiratory function immediately postoperatively and most have protracted long-term survival after pneumonectomy for a variety of pulmonary diseases.
