The authors have developed a procedure to evaluate the performance of cerebral aneurysm clips as a function of intravascular pressure and aneurysm neck diameter. Numerous models of Mayfield, Scoville, Variangle, Heifetz and Yasargil clips were tested. The various clips demonstrated decreasing capabilities for secure occlusion of a vessel as vascular diameters and intravascular pressure increased. These findings are in record with predictions based upon La Place's Principle and indicate that the size of an aneurysm must be considered in the choice of an appropriate aneurysm clip.
作者们开发了一种程序，用于评估脑动脉瘤夹的性能与血管内压力和动脉瘤颈部直径之间的关系。对Mayfield、Scoville、Variangle、Heifetz和Yasargil夹的多种型号进行了测试。随着血管直径和血管内压力的增加各种夹子在牢固夹闭血管方面的能力逐渐下降。这些发现与基于拉普拉斯原理的预测相符，表明在选择合适的动脉瘤夹时必须考虑动脉瘤的大小。
