In vitro porcine arteries and veins have been welded end-to-end using either a 808 nm diode laser combined with an indocyanine green enhanced albumin solder, or with a continuous-wave (cw) Ho:YAG laser without biological solder. The vascular stumps were approached to each other over a coronary dilatation catheter in order to obtain a precise alignment and good coaptation. Standard histology revealed for both welding techniques lateral tissue damage between 2 and 3 mm caused by laser-induced heat. Good solder attachment to the tissue was observed by the use of a scanning electron microscope. The vessels soldered with the 808 nm diode laser using albumin solder showed considerably higher tensile strength (1 N compared to 0.3 N) than vessels welded exclusively by Ho:YAG laser radiation. In contrast, leaking pressure (350 +/- 200 mmHg) and bursting pressure (457 +/- 200 mmHg) were found to be independent of the welding technique used. This study demonstrates that fast (total welding time about 2-5 min), stable and tight microvascular anastomosis can be achieved with the use of a dye-enhanced albumin laser soldering technique and an ancillary coronary dilatation catheter.

“…The ratio of vascular thrombosis reported in free flap surgery varies between 5.1% and 9.9% (11-13), and for the prevention of this complication, in addition to the suggestions of agents such as botulinum toxins, low molecular weight heparins, aspirin, prostaglandins, dextran inhibitors, and other various agents (14)(15)(16)(17)(18)(19)(20)(21)(22), studies on anastomosis have also been carried out (23)(24)(25)(26)(27)(28)(29).…”

Objective: In free flap surgery, the condition of recipient vessels may not be appropriate for anastomosis because of anatomical factors or acquired features such as tumoral invasion, surgical treatment, or radiotherapy. Furthermore, free flap surgery is time-consuming, expensive, demanding, and more prone to complications. The aim of this study was to test the hypothesis that maintaining free flap perfusion with a temporary artificial system without microanastomosis until revascularization is adequate for flap vitality. Materials and Methods:We studied a total of 14 rabbits, which were placed into two groups: control and experimental. A 5×5 cm free skin island flap was elevated on the caudolateral scapular region. In the experimental group, the artery and vein of the flaps were cannulated and a 5 cc/h plasma infusion was artificially started prior to flap fixation. In the control group, the flaps were designed and sutured to the recipient area without perfusion.Results: The animals did not live long enough for us to analyze the maintenance of the clinical flap vitality. However, it was found that flap tissues in the experimental group were vital during the first 6 days after surgery, while composite graft tissues in the control group resulted in necrosis on day 3 in histopathological examination.Conclusion: Our experimental model proves that the artificial flap perfusion model with plasma perfusion extends the duration of tissue viability compared with that with non-perfusion (control group). This result could be improved with further investigations and may lead to the development of many future innovations.

Laser techniques for joining tissue, in combination with other surgical technologies, will be a hallmark of surgery in the next century. At present, there are many clinical applications of tissue welding and soldering which are beginning to achieve wide spread acceptance. These exciting clinical developments are the result of many advances which have been made in the past few years in our understanding of the mechanism of laser tissue welding. Also contributing to this progress are many important technical refinements such as tissue solders and feedback control of the laser device. In this article, we describe in depth the history and development of laser tissue welding including key theoretical concepts as well as crucial experiments which have added to our insight into this phenomenon. We also review the evolving concepts of its clinical application and indicate clinical applications which are likely to become more important in the future.
