Thoracoscopy is a minimally invasive operative endoscopic procedure designe
d for visual inspection of the thoracic cavity. The use of small, highly ma
neuverable, rigid telescopes allows visualization beyond what is possible b
y standard operative techniques. The use of a small video camera attached t
o a standard rigid telescope allows the operator and assistants to view a s
imultaneous, enlarged, and clear image. This article focuses on the basic d
iagnostic and surgical techniques used in veterinary video-assisted thoraco
scopy.
