由于光学纤维技术、经皮冠状动脉腔内成形术(PTCA)和激光治疗实验的进展,血管内窥镜、尤其是冠状动脉内窥镜检查,最近又受到了重视.本文报告冠状动脉内窥镜检查的经验.方法:采用长度为120cm的两种超细型纤维内窥镜(Olympus,PF18L:直径1.8mm,观察深度3～30mm;PF14L:直径1.4mm,观察深度2.1～∞mm).照明用300W氙光源,用多倍放大照相机或录像装置记录.分4组进行检查:(1)尸检 7例尸心,用9F导管分别插入两侧冠状动脉口,经导管用等惨生理盐水冲洗,同时引入内窥镜.(2)经皮血管镜检查 16例疑为冠心病患者于心导管检查术后进行了血管镜检查.在X线监视下经右侧股动脉插入9F导引管至主动脉,通过此管引入PF18L内窥镜.生理盐水冲洗总量限制在700ml以下.(3)经皮冠状动脉内窥镜检查 8例冠心病患者于球囊扩张术
Due to advances in optical fiber technology, percutaneous transluminal coronary angioplasty (PTCA) and laser treatment experiments, recently, more attention has been given to endoscopic vascular examinations, especially coronary endoscopies. Inspection Methods: Two types of ultrafine fiber endoscope (Olympus, PF18L: diameter 1.8mm, observation depth 3 ~ 30mm; PF14L: diameter 1.4mm, observation depth 2.1 ~ ∞mm) With 300W xenon light source, with a magnification of the camera or video recording device. Divided into 4 groups were examined: (1) autopsy 7 cases of corpse, with 9F catheter were inserted into both sides of the coronary artery port, catheterization and other miserable saline flush, At the same time, the endoscope was introduced. (2) Percutaneous vascular examination of 16 patients suspected of coronary heart disease underwent cardiac catheterization after angiography .In the X-ray monitoring, the right femoral artery insertion of 9F guide tube to the Lord Arterial, the introduction of PF18L endoscope through this tube, the total amount of saline flushing limited to 700ml or less. (3) percutaneous coronary artery endoscopy 8 patients with coronary heart disease in balloon dilatation
