深度冷冻治疗对许多表浅肿瘤是有效的,最近正试用于内脏肿瘤的治疗。本文目的是探讨深度冷冻治疗应用于肺实质局限区域的安全性,并评价其对组织愈合的作用。方法:冷冻探头用液氮作为致冷源,可在激发的几秒钟内冷却至-180℃。6条狗在麻醉下从第5肋间行左前剖胸暴露左上叶的舌段,施加3个冷冻/融解周期,每一周期使冷冻探头尖部达到-120℃,维持
Deep cryotherapy is effective for many superficial tumors and is currently being tested for the treatment of visceral tumors. The purpose of this article is to investigate the safety of deep cryotherapy in the restricted area of lung parenchyma and to evaluate its effect on tissue healing. METHODS: The cryoprobe was cooled with liquid nitrogen as a cooling source and cooled to -180°C within a few seconds of excitation. Six dogs under anesthesia from the fifth intercostal line left anterior thoracotomy exposed the tongue segment of the left upper lobe, applied three freeze / thaw cycles, each cycle to the frozen probe tip -120 °C, maintain
