作者报道了2例铂圈治疗的椎基底动脉复合性动脉瘤。例1为48岁的女性,CT示弥散性蛛网膜下腔出血,导致脑基底池内积血。椎动脉造影示基底动脉顶端有一较大的囊状动脉瘤(宽颈),右大脑后动脉(PCA)直接起源于其基底部;同时,右侧后交通动脉有一小囊状动脉瘤(已经手术夹闭)。术后一周,上述宽颈的基底动脉瘤因手术治疗难度大,而采用铂圈治疗。起初使用7个铂圈(直径为4mm,长6 cm),经Tracker-18号导管送到动脉瘤处,闭塞了大约40%的瘤腔。一周后血管造影显示瘤腔内无血栓形成。因此又使用8个0.018吋缠绕涤纶纤维的铂圈(直径5 mm,长1.5cm),经导管送到动脉瘤处,闭塞了大约60%的瘤腔,动脉瘤的
The authors reported two cases of platinum-based vertebrobasilar artery aneurysm. Example 1: A 48-year-old woman with diffuse subarachnoid hemorrhage on CT showed hemorrhage in the basal cistern. Vertebral artery angiography showed a large saccular aneurysm (wide neck) at the tip of the basilar artery. The posterior cerebral artery (PCA) originated directly from the base of the basilar artery. Meanwhile, there was a small saccular aneurysm in the right posterior communicating artery Closure). One week after the surgery, the wide-necked basilar artery aneurysm was treated with platinum ring because of the difficulty of surgical treatment. Initially, seven platinum rings (4 mm in diameter and 6 cm in length) were used and were delivered to the aneurysm via the Tracker-18 catheter, occluding about 40% of the tumor cavity. One week later angiography showed no thrombus in the tumor cavity. Thus, another eight 0.018 inch platinum coils (5 mm in diameter and 1.5 cm in length) wrapped with polyester fibers were delivered via catheter to the aneurysm, occluding about 60% of the tumor cavity, aneurysm
