Pulmonary Artery Sealing With an Ultrasonic Energy Device in Video-Assisted Thoracoscopic Surgery Lobectomy: An Animal Survival Study.
Pulmonary artery (PA) sealing in video-assisted thoracoscopic surgery (VATS) lobectomy is typically accomplished using vascular endostaplers. Endostaplers may be associated with iatrogenic PA branch injury, especially in short, small PA branches. We evaluated PA branch sealing with the HARMONIC ACE +7 (ACE) shears (Ethicon, Cincinnati, OH) in VATS lobectomy in a canine survival model. ⋯ The use of the ACE for PA branch sealing in VATS lobectomy is safe and effective in an animal survival model. Human studies are needed to determine the clinical safety of ultrasonic PA branch sealing before widespread clinical use.
