A Case of Lobar Emphysema in a Dog.

Surgical Correction of Congenital Lobar Emphysema in a Dog

“…Bronchial cartilage dysplasia [2,4,7], hypoplasia [1,6], and aplasia [8] were noted in later reports, and we observed bronchial hypoplasia in our own case. The same as Karnak et al pointed out in humans [5], there appears to be a close relationship between lobar emphysema and bronchial cartilage abnormalities in the dog too.…”

“…Based on the total of four cases reported thus far, consisting of two cases of congenital lobar emphysema [1,2], one likely case [6], and our own case, surgery seems to have been the most common form of treatment for emphysema in a single relatively small lobe, because the lesions were limited to the right middle lobe in three out of the four cases and in the other it was limited to the left cranial lobe. If the emphysema is multifocal and/or in a large lobe, it is important to determine the suitability of surgery and to make a prognosis.…”

Thoracoscopic treatment of bullous emphysema in 3 dogs

“…Clinical management of spontaneous pneumothorax by repeated thoracocentesis followed by chest tube aspiration has a poor prognosis (25% to 100% recurrence), so surgical treatment is recommended 2‐6 . This requires exploratory thoracotomy, recognition of the affected tissue, and partial lobectomy 2‐11 . For generalized emphysematous disease, no curative treatment is known, and, in most cases, euthanasia is warranted 6‐10 .…”

“…The typical radiographic pattern of bullous disease has been described as a cystic hyperlucent zone at the margins of lung lobes 1‐11 . Radiographic identification of bullous disease has been reported in 5% to 50% of cases 2‐5 .…”

“…Spontaneous pneumothorax is a nontraumatic closed pneumothorax in which the lung is the source of air accumulation 1 . Previous retrospective studies assume that most spontaneous pneumothorax results from emphysematous disease and blebs, or bullae ruptures 2‐11 . When pleural drainage does not allow control of air accumulation, the definitive treatment is an explorative thoracotomy by an intercostal or a transsternal approach 2‐6 .…”
