Drug-coated balloon catheters (DCB) are a new clinical treatment modality for coronary and peripheral artery disease. The goal of the consensus group is to develop recommendations for the clinical use of DCB based on randomized clinical trials and the best available clinical evidence. The present paper gives an update on the recommendations against the background of a variety of new data published since the first paper was presented.
The general concept of our recommendations for the coronary use of DCB includes the preparation of the lesion to facilitate drug delivery and to estimate the need for stent implantation, especially after relevant dissections. Lesion preparation includes conventional angioplasty. In more complex lesions, additional treatments and imaging or functional measurements are helpful. In case of no flow-limiting dissection and an acceptable but not stent-like primary result, DCB use without additional stent implantation may be considered. The proposed advantages of the DCB only concept over a direct stent approach include reduced restenosis rates in indications where DES show limited efficacy, the reduction of DAPT especially in patients with contraindications for prolonged DAPT, and the option of leaving no foreign object behind resulting in vascular restoration with potentially plaque regression instead of neo-atherosclerosis.
DCB allow for local drug delivery in endovascular therapy leaving no permanent implant behind.
药物涂层球囊导管(DCB)是一种治疗冠状动脉和外周动脉疾病的新的临床治疗方法。共识小组的目标是根据随机临床试验和最佳现有临床证据,制定 DCB 的临床应用建议。本文在第一篇论文发表后公布的各种新数据的背景下,更新了这些建议。
我们对冠状动脉 DCB 使用的建议的总体概念包括准备病变以促进药物输送并估计支架植入的需求,特别是在相关夹层后。病变准备包括传统的血管成形术。在更复杂的病变中,额外的治疗和成像或功能测量是有帮助的。如果没有血流受限的夹层,且初始结果可以接受但不类似于支架,则可以考虑不额外植入支架而使用 DCB。与直接支架方法相比,DCB 仅概念的优势包括减少 DES 疗效有限的适应证中的再狭窄率,减少 DAPT 特别是在存在延长 DAPT 禁忌的患者中,以及选择不留下异物,从而导致血管恢复,可能伴有斑块消退而不是新生动脉粥样硬化。
DCB 允许在血管内治疗中进行局部药物输送,而不会留下永久性植入物。
