Rectus sheath block results in greater cranial-caudal spread whereas transversus abdominis plane block results in greater lateral spread as assessed by computed tomography in dogs.

Objective: To evaluate the in vivo spread of iodinated contrast following injections in the transversus abdominis plane (TAP) and rectus sheath in anesthetized dogs via computed tomography. Secondarily, the time of performing each block was compared.

Animals: 6 adult, purpose-bred Beagles.

Thoracoscopic resection of lung masses is associated with excellent survival to discharge and good long-term outcomes.

Objective: To report and evaluate risk factors for conversion and perioperative and long-term outcomes in dogs undergoing thoracoscopic lung lobectomy for resection of lung masses.

Animals: 61 client-owned dogs.

Methods: This retrospective cohort study (June 11, 2008, to February 14, 2020) of data collected from medical records included signalment, results of diagnostic imaging, surgical technique, surgical and anesthesia time, mass location and size, hospitalization time, histopathologic findings, and long-term outcome.
