Surgical cannulation of a hepatic vein in dairy cows utilizing diagnostic ultrasound.
Use of a diagnostic ultrasonography unit in the placement of hepatic vein catheters is described. Diagnostic ultrasound proved to be a safe and rapid means of identifying the hepatic venous circulation. It provided a clear visual guide in an otherwise blind surgical procedure and allowed for a precise determination of catheter placement. Thus, the method could be used to advantage in other types of catheterizations. Use of ultrasonography reduced the duration of surgery by 50 to 75%, thereby minimizing the risks associated with long-term general anesthesia and reducing recovery time.
