A Quantifiable Bleeding Gastric Ulcer in Dogs for Assessing the Neodymium Yag Laser
17 March 2008 (online)
A quantifiable arterial bleeding gastric “ulcer” was produced in 6 dogs using the splenic artery with a mean flow rate varying from 50-120 ml/min-1.
Using a new Neodymium Yag laser system (Barr and Stroud) and glass fibre through a fibreoptic endoscope, bleeding was successfully arrested. Coaxial CO2 allowed adequate visualization of the spurting vessel and the helium neon laser was a satisfactory marker for aiming.
