“…Thoracic effusion found in three of the 14 dogs was probably due to pulmonary neoplasms (Fossum 2008). Thoracoscopy was a safe diagnostic tool, easy to perform and without major complications even in patients with pulmonary involvement, with a stable clinical picture corroborating with the literature (McCarthy & McDermaid 1999).…”

Lung biopsy with guillotine cutting needle and biopsy forceps though transdiaphragmatic thoracoscopy in dogs with pulmonary alterations

Lung diseases are common in small animal clinical routine. Diagnosis is usually affected due to nonspecific symptoms. Imaging features such as radiography and chest ultrasound are acceptable screening tests, although lung biopsy can provides a precise diagnosis. Thus thoracoscopy provides a minimally invasive diagnostic assessment for chest diseases and offers the benefits such as improved illumination and magnification of the image when compared with thoracotomy. In this study we evaluated the transdiaphragmatic thoracoscopic-assisted techniques of lung biopsy with a the guillotine cutting needle and biopsy forceps, in dogs presenting radiographic suspicion on pulmonary tumors. Fourteen dogs regardless of breed, gender, age and body weight admitted at the Hospital of Veterinary Clinics (HCV) of the Veterinary College (FAVET) of Universidade Federal do Rio Grande do Sul (UFRGS), were assessed. Inclusion criteria were presence of nodules on chest radiography and triage tests without changes that could hinder general anesthesia and surgical approach. The animals were positioned in dorsal recumbence and two thoracoscopic ports were established: the first port for working instruments; the second paraxyphoid port for the telescope. Three samples were collected using each sampling method from each lesion or from tumors macroscopically similar whenever their size was less than one centimeter. The samples were sent for histopathological examination in the Veterinary Pathology Laboratory of FAVET/UFRGS. Surgical time was recorded from first incision to wound closure and surgical complications were reported. The dogs were evaluated for the presence of subcutaneous emphysema, hematoma, seroma, local infection and dehiscence. No conversion to open surgery was necessary during the thoracoscopic procedure in any patient. Thoracoscopic assisted biopsy using guillotine needle and biopsy forceps was a safe and fast technique, without perioperative complications. Both devices provided good quality samples for histopathological analysis of lung abnormalities. However the cutting guillotine needle was more efficient especially in larger pulmonary nodules. The transdiaphragmatic access provided optimal approach for both hemithoraces.

“…Thoracoscopy offers many potential advantages over thoracotomy in both cats and dogs, those documented previously include decreased postoperative pain, decreased complications (such as wound dehiscence, seroma formation and front limb lameness), much smaller incisions and quicker recovery times (Walsh et al, ; Dupre et al, ; Monnet, ; Davidson et al, ). Pericardial effusions can be accurately and effectively drained under thoracoscopic guidance, and tissue samples can be collected for histological examinations (McCarthy and McDermaid, ; McCarthy, ). Significant pericardial effusions are rare in the cat and cardiac tamponade is seldom seen (Rush et al, ; Bouvy et al, ; Davidson et al, ; Nelson et al, ).…”

A 15-year-old, neutered male domestic shorthair cat was presented to the referring veterinary surgeon with inappetence, lethargy hyperpnoea and increased inspiratory effort of two days' duration. Thoracic radiographs and echocardiography revealed a pericardial effusion and pleural fluid consistent with right-sided congestive heart failure (RCHF). Single pericardiocentesis and management for RCHF (furosemide) did not lead to a significant improvement and the cat was referred five days after the start of the signs At presentation, the cat was alert, responsive and in good body condition. Physical examination revealed tachypnea (60 breaths per minute) with increased inspiratory and expiratory effort. Auscultation of heart and lungs from both sides revealed reduced heart and breath sounds respectively. Peripheral pulses were weak and distension of both jugular veins was noted.Haematology revealed a neutrophillia 20.6x10 9 /l (reference: 3.0-11.5x10 9 /l), ALT 340 iμ/l (reference: 0-50 iμ/l), AST 363 iμ/l (reference: 0-69 iμ/l) and ALP 79 iμ/l (ref. 0-40 iμ/l) were all increased. Thoracoscopicpericardiectomy forthemanagementofa neoplasticpericardialeffusionA 15-year-old domestic shorthair cat was presented with a five-day history of progressive inappetence, lethargy and dyspnoea. Thoracic radiographs revealed pleural effusion and suggested pericardial effusion. Echocardiography revealed a pericardial effusion, cardiac tamponade and focal thickening of the pericardium. Diagnostic and therapeutic pericardiocentesis was performed and led to immediate but short-term alleviation of the clinical signs. Both the pleural and pericardial effusion were modified transudates and contained reactive mesothelial cells. Thoracoscopic pericardiectomy was performed which revealed a moderate amount of pleural effusion, and a diffusely thickened and irregular pericardium but no other abnormalities were found. Histopathological examination of the pericardium revealed an aggressive anaplastic carcinoma. Thoracoscopy gave a far superior visualisation of thoracic structures compared to that expected at open thoracotomy. Thoracoscopic pericardiectomy was an efficient procedure with a good postoperative recovery.

“…Os estudos iniciais restringiram-se à exploração diagnóstica da cavidade (McCARTHY & McDERMID, 1990). Porém, ultimamente a toracoscopia vem ganhando terreno também na Medicina Veterinária, sendo utilizada experimentalmente nas biópsias pulmonares, lobectomias (GARCÍA et al, 1998) e pericardiectomias (WALSH et al, 1999) O presente estudo objetivou avaliar o acesso toracoscópico no diagnóstico e na terapêutica cirúrgica de hérnias diafragmáticas produzidas experimentalmente em cães.…”
