We report a case of rupture and fragmentation of a PET-balloon catheter during percutaneous transluminal coronary angioplasty of a calcified LAD-obstruction. When the insufflation pressure was increased to 12 atm, the balloon ruptured. During withdrawal of the balloon catheter the tip of the shaft and a fragment of the balloon tore off and remained within the atheroma. Emergency operation was necessary to remove the fragments and to prevent a large myocardial infarction. Although this is an unusual complication of PTCA, care should be taken when PET-balloon catheters are used in calcified coronary obstructions.
我们报告了1例在对钙化的左前降支梗阻进行经皮腔内冠状动脉成形术期间，PET球囊导管发生破裂和碎裂的病例。当充气压力增加到12个大气压时，球囊破裂。在撤出球囊导管的过程中，导管尖端和球囊的一个碎片脱落并留在粥样硬化斑块内。需要进行紧急手术以取出碎片并预防大面积心肌梗死。虽然这是经皮腔内冠状动脉成形术（PTCA）的一种罕见并发症，但在钙化性冠状动脉梗阻中使用PET球囊导管时应谨慎。
