作者试图创造一种血管内激光导管技术,既便于治疗其些破裂的颅内动脉瘤,也可用于诊断性血管造影。用20只新西兰白兔,借助于手术显微镜,手术产生20个实验的颈总动脉瘤,大小为3.5×3～8×7.5mm。动脉瘤产生后5天,用4F 导向导管经股行颈动脉造影,证实动脉瘤未闭。治疗动脉瘤用带小钢帽的球囊导管-光纤维系统:直径为100μm硅轴光纤维穿过1.8F 聚氟乙烯导管,并伸出2cm,导管远端附着一短段胶乳套,套的另一端紧扎在光
The authors sought to create an intravascular laser catheter technique that is both useful in the treatment of some of its ruptured intracranial aneurysms and may also be used in diagnostic angiography. Twenty new Zealand white rabbits were operated surgically to produce 20 experimental carotid aneurysms measuring 3.5 × 3 to 8 × 7.5 mm. Five days after the aneurysm was established, a 4F-guided catheter was used to identify the aneurysm with a patent carotid artery. Balloon Catheter with Small Cap for the Treatment of Aneurysms - Optical Fiber System: A silicon optical fiber with a diameter of 100 μm was passed through a 1.8 F polyvinylidene fluoride catheter and extended 2 cm. A short piece of latex was attached to the distal end of the catheter, The other end is tight in the light
