A combination of the Sundt-Kees reinforcing aneurysm clip applied to a Drake aneurysm clip in a piggyback fashion was studied for possible defects due to corrosion and or tissue toxicity. These two clips, which are made of similar metal (301 stainless steel), showed little or no defects when immersed in 5% saline or when implanted in rats for 6 months. This study demonstrates that clips made of similar metals can be used piggyback in patients without ill effects provided that they are carefully handled to avoid any abrasion or misbends which could conceivably lead to corrosion.
研究了以背驮方式将森特-基斯加强型动脉瘤夹应用于德雷克动脉瘤夹的组合，以检测其是否存在因腐蚀和（或）组织毒性导致的潜在缺陷。这两种夹子由相似的金属（301不锈钢）制成，当浸入5%的盐水中或植入大鼠体内6个月时，几乎没有出现缺陷。这项研究表明，由相似金属制成的夹子可以在患者身上以背驮方式使用而不会产生不良影响，前提是要小心操作以避免任何可能导致腐蚀的磨损或弯曲。
