To devise a method to measure aneurysm neck size on angiographic films, and to correlate the sizes obtained with the extent of endovascular aneurysm occlusion, performed with electrically detachable coils.
The angiograms of 79 intracranial aneurysms treated by endovascular occlusion using electrically detachable coils were retrospectively analyzed. A method using the average reported caliber of the major intracranial vessels was applied to determine the aneurysm neck sizes on the diagnostic angiograms. The cases were divided into two groups according to neck size, 4 mm being the discriminative value for small and wide necks. The posttreatment angiogram of each case was analyzed to evaluate the degree of occlusion achieved by the technique.
Necks were successfully measured in 95% of the aneurysms. Complete aneurysm thrombosis was observed in 85% of the small-necked aneurysms and in 15% of the wide-necked aneurysms.
Accurate angiographic measurements of neck diameter can be obtained in most aneurysms. The size of an aneurysm neck correlates well with the results of the endovascular treatment. Small-necked aneurysms can be satisfactorily occluded with this technique. In wide-necked aneurysms this technique should be reserved for lesions having a high surgical risk.
设计一种在血管造影胶片上测量动脉瘤颈部大小的方法，并将所获得的大小与使用电可脱性弹簧圈进行的血管内动脉瘤闭塞程度相关联。
回顾性分析79例使用电可脱性弹簧圈进行血管内闭塞治疗的颅内动脉瘤的血管造影。应用一种使用主要颅内血管报告的平均管径的方法来确定诊断性血管造影上的动脉瘤颈部大小。根据颈部大小将病例分为两组，4mm作为小颈和宽颈的判别值。分析每个病例的治疗后血管造影以评估该技术所达到的闭塞程度。
95%的动脉瘤成功测量了颈部。85%的小颈动脉瘤和15%的宽颈动脉瘤观察到完全动脉瘤血栓形成。
大多数动脉瘤可获得准确的血管造影颈部直径测量。动脉瘤颈部大小与血管内治疗结果密切相关。小颈动脉瘤用该技术可得到满意闭塞。在宽颈动脉瘤中，该技术应保留用于手术风险高的病变。
