Needle biopsy of the liver is a common diagnostic procedure. Although relatively safe, bleeding remains a potential complication and may occur more frequently in patients with coagulopathy. The purpose of this study was to evaluate the utility of a fibrin sealant in preventing bleeding after a 15-gauge needle biopsy of the liver in a canine model heparinized to simulate coagulopathy.
Fibrin sealant was delivered to biopsy tract sites in eight dogs anticoagulated with heparin (activated clotting time 387 seconds +/- 94) using the same sheath system that was employed to obtain the biopsy specimen.
The results demonstrated complete hemostasis in the sealant-plugged tracts as compared to controls. Continuous bleeding was observed in none of the fibrin sealant-treated sites, compared with all of the control biopsy sites (P = .0078).
These results demonstrate the high degree of efficacy of fibrin sealant delivered through a sheath system in plugging liver biopsy tracts and eliminating bleeding in a severely coagulopathic animal model. This indicates that fibrin sealant use in cutting needle biopsies can reduce major and minor complications associated with the procedure.
肝脏穿刺活检是一种常见的诊断方法。虽然相对安全,但出血仍是一种潜在并发症,在凝血功能障碍患者中可能更频繁发生。本研究的目的是评估在犬类模型中,通过肝素化模拟凝血功能障碍,使用纤维蛋白密封剂预防15号肝脏穿刺活检后出血的效用。
使用获取活检标本时所用的相同鞘管系统,将纤维蛋白密封剂输送至8只经肝素抗凝(活化凝血时间387秒±94)的犬的活检通道部位。
结果显示,与对照组相比,密封剂封堵的通道实现了完全止血。纤维蛋白密封剂处理的部位均未观察到持续出血,而所有对照活检部位均出现持续出血(P = 0.0078)。
这些结果表明,通过鞘管系统输送的纤维蛋白密封剂在封堵肝脏活检通道和消除严重凝血功能障碍动物模型中的出血方面具有高度有效性。这表明在切割针活检中使用纤维蛋白密封剂可减少与该操作相关的主要和次要并发症。
