A new technique of vascular endoscopy employing fiberoptic endoscope and balloon catheter was devised. Experimental and clinical studies showed excellent visual field and optical quality. Our technique of vascular endoscopy has several advantages. First, the size of the balloon is large enough to obtain satisfactory visual field and can be applied to the great vessels. Second, the endoscope can be advanced or withdrawn in the balloon catheter during balloon inflation. Third, the endoscope is never in contact with blood, so thrombus formation can be prevented and complete sterilization can be achieved. Fourth, no blood is lost during the procedure because the graft is snugly tightened to the hard portion of the catheter. Vascular endoscopy is useful to observe orifices of the major aortic branches, to distinguish atheromatous plaque from thrombus, and to identify unexpected intimal tears by vascular clamps, which cannot be achieved by operative angiography. It is particularly useful for identifying the exact site of the entry or reentry in dissecting aneurysm. Although our experience was limited to intraoperative use, vascular endoscopy can be an invaluable method to examine, diagnose, and treat the patient who requires aortic, caval, or other major vascular surgery.
设计了一种采用纤维内镜和球囊导管的血管内镜新技术。实验和临床研究显示视野和光学质量极佳。我们的血管内镜技术有几个优点。第一，球囊大小足以获得满意的视野，可应用于大血管。第二，在内镜球囊充气时，内镜可在球囊导管内前进或后退。第三，内镜从不与血液接触，因此可防止血栓形成并实现完全消毒。第四，手术过程中无血液流失，因为移植物紧密贴合导管的硬质部分。血管内镜有助于观察主动脉主要分支的开口、区分动脉粥样硬化斑块与血栓，以及识别血管夹导致的意外内膜撕裂，而手术血管造影无法做到这一点。它对于确定夹层动脉瘤入口或再入口的确切位置特别有用。虽然我们的经验仅限于术中使用，但血管内镜对于需要进行主动脉、腔静脉或其他大血管手术的患者来说，可能是一种非常宝贵的检查、诊断和治疗方法。
