However, in-stent restenosis （ISR） has been the downside of all coronary interventions with the devices that have been tested so far, even in the DES era. The impact of ISR is still an important issue due to the recurrent costs from need for repeat PCI and bypass surgery in some patients who underwent PCI with DES. A safe and cost-effective method is desired to overcome this unfavorable burden following PCI with DES. Vascular brachytherapy （VBT） is one of the approved indications and has evolved over a decade as a valuable alternative to treat ISR.
