Laser-assisted treatment of patients with hemorrhagic diathesis

摘要

Abstract: Today more and more patients with bleeding disorder come to our office for treatment. The number of patients with therapeutic anticoagulation is growing steadily. Discontinuation of this therapy can often be crucial. On the other hand are oralsurgical procedures extremely sensitive to bleeding due to the constant presents of saliva with its high fibrinolytic activity. The aim of this study was to evaluate the use of a surgical diode (wavelength 810 nm) laser as accessory tool in the treatment of patients with hemorrhagic diathesis. Enclosed in the study were 123 patients with: (1) Coumarintherapy, a Quick test ratio of 15 - 25%; (2) More than 300 mg of ASS/die; (3) Hemophilia, a factor activity under 35%; (4) Morbus Werlhof with less than 30000 thrombocytes. 179 Surgical procedures: (1) Tooth extraction 86%; (2) Apexectomy 3%; (3) Tumorexcision 9%; (4) Curettage and flapsurgery 1%; (5) Gingivectomy 1%. All procedures were laser-assisted with a diode laser emitting 810 nm. The glass fibers used were depending on the procedures either 200, 400, or 600 micron. No coagulating agents or tissue adhesives were used in addition. The postoperative outcome and complication rates were compared to substitution therapy and tissue adhesives. Laser-assisted treatment of these patients shows a high predictability and success rate leaving out side effects of drugs and human cryoprecipitates. Postoperative impairment is diminished. !26
