A 65-year-old man with a restenotic lesion of the mid LAD was scheduled for Wiktor stent placement. The IVUS revealed circumferential severe calcification. Two conventional, non-compliant angioplasty balloons inflated to high pressures failed to achieved sufficient dilatation and both ruptured. At this point, we selected high pressure inflation of the Cutting Balloon. The Cutting Balloon achieved adequate dilation for stenting and proved to be useful in predilating a circumferential, heavily calcified lesion.
一名65岁男性，前降支中段存在再狭窄病变，计划行维克托支架置入术。血管内超声显示环形严重钙化。两个传统的、非顺应性血管成形术球囊在高压下充气未能实现充分扩张，且均破裂。此时，我们选择使用切割球囊进行高压充气。切割球囊实现了足够的扩张以利于支架置入，并且证明在预扩张环形重度钙化病变方面是有用的。
