摘要

傳統的自由瓣術後監測方法並不全然適用於隱藏性自由瓣。1988年Swartz等人率先應用植入型20兆赫超音波都卜勒探測器於一大規模的動物和臨床試驗。我們提供一個案報告關於使用Cook-Swartz都卜勒血流監測系統，於咽食道重建之隱藏性橈前臂自由皮瓣之術後循環監測。這套系統提供了一個簡單又可靠之監測微循環的方法，可以省去加護病房或類似之顯微術後照護單位相關人力及物力。將都卜勒探測器置於自由瓣靜脈之監測能提供較好的敏感性並增加自由瓣的成功率及挽救率。我們相信使用Cook-Swartz都卜勒血流監測系統於隱藏式自由瓣的術後監測為一相當有效的方法，並提供傳統監測方法一項輔助。

Reconstructive microsurgeon is constantly striving to improve the success and salvage rates of free tissue transfer. Conventional free flap monitoring techniques are reliable for non-buried flaps. Buried flap monitoring is still a dilemma. In 1988, Swartz et al. did the first large-scale study of direct monitoring of microvascular anastomoses with the implantable 20-MHz ultrasonic Doppler probe. We present a case using the Cook-Swartz Doppler blood flow monitoring system for the postoperative monitoring of the buried free forearm flap in pharyngoesophageal reconstruction. It is a simple and reliable method of monitoring microvascular anastomoses without need for intensive care or monitoring units. The venous probe provides a greater degree of sensitivity, particularly to venous occlusion, compared with the arterial probe and has resulted in an increased success and salvage rate. We believed our initial case experience with this device supports the use of Cook-Swartz Doppler blood flow monitoring system as a promising technique for monitoring buried flaps and an adjunct to traditional clinical observation.
