Biological effects of laser welding on vascular healing.
Rodney A. White,R.P. Abergel,Richard Lyons,Stanley R. Klein,George E. Kopchok,Richard M. Dwyer,Jouni Uitto +6 more
TL;DR: This report summarizes the experience using laser welding to repair thick‐walled, high‐pressure, 4 to 8‐mm canine arteries using CO2, Nd:YAG, and argon lasers and suggests laser welding may represent an alternative for repair of small‐and large‐diameter vessels with several advantages compared to conventional suture techniques.

Skin closure by Nd:YAG laser welding.
R. Patrick Abergel,Richard Lyons,Rodney A. White,Gary Lask,Lois Y. Matsuoka,Richard M. Dwyer,Jouni Uitto +6 more
TL;DR: It is suggested that laser welding might have advantages over suturing, since the former is sterile and nontactile, does not require introduction of foreign material into the wound, and provides subjectively improved cosmetic results.

Comparison of laser-welded and sutured arteriotomies.
Rodney A. White,George E. Kopchok,Carlos E. Donayre,R. Patrick Abergel,Richard Lyons,Stanley R. Klein,Richard M. Dwyer,Jouni Uitto +7 more
TL;DR: Histologic examination revealed that laser-welded arteriotomies had less inflammatory reaction, more normal collagen and elastin reorientation, and similar endothelial continuity when compared with the control, sutured wounds, suggesting that argon laser welding may be an alternative to suture repair of arteriotmies.

Argon laser-welded arteriovenous anastomoses
Rodney A. White,George E. Kopchok,Carlos E. Donayre,Geoffrey H. White,Richard Lyons,Roy M. Fujitani,Stanley R. Klein,Jouni Uitto +7 more
TL;DR: It is concluded that argon laser welding of anastomoses is an acceptable alternative to suture techniques, with the advantage of improved healing without foreign body response and possible diminished intimal hyperplasia at theAnastomotic line.

Large vessel sealing with the argon laser
Rodney A. White,George E. Kopchok,Carlos E. Donayre,Richard Lyons,Geoffrey H. White,Stanley R. Klein,Damon Pizzurro,R. Patrick Abergel,Richard M. Dwyer,Jouni Uitto +9 more
TL;DR: Histologic and biochemical examination and tensile strength determinations suggest that laser welding may be an alternative to sutures for repair of large‐diameter venotomies, arteriotomies, and arteriovenous fistulas, as healing is comparable to that seen with suture repairs up to 4 weeks postoperatively.
