Abstract

Percutaneous coronary intervention for true bifurcation lesions is challenging because they have a poor prognosis due to side branch (SB) complications. The modified jailed balloon technique (MJBT) is useful for significant SB protection. However, even with the MJBT, provisional stenting in true bifurcation lesions does not dispel the risk of SB occlusion because re-crossing the guidewire through the stent struts into the SB remains a challenge, particularly when SB dissection occurs after stent implantation. Recently, the rewiring of dissected branches along the jailed balloon (real JAB) technique has been reported as a bailout method for this issue. We present the first series of successful provisional stenting cases in five patients with true bifurcation lesions using the real JAB technique in combination with the MJBT.

在为真正的冠状动脉分叉病变提供临时支架时,沿囚禁球囊技术重新布线剥离的分支
经皮冠状动脉介入治疗真正的分叉病变具有挑战性,因为这些病变由于侧支(SB)并发症而预后较差。改良锚定球囊技术(MJBT)可有效保护侧支。然而,即使使用 MJBT,在真正的分叉病变中进行临时支架植入术也不能消除 SB 闭塞的风险,因为将导丝重新穿过支架支柱进入 SB 仍是一项挑战,尤其是在支架植入后发生 SB 夹层的情况下。最近有报道称,沿 "囚禁球囊(real JAB)"技术重新布线剥离的分支是解决这一问题的一种救助方法。我们介绍了第一批使用真正的 JAB 技术并结合 MJBT 成功为五例真正的分叉病变患者进行临时支架植入术的病例。
