血管内放射治疗的远期疗效和并发症

Long-term Effects and Complications of Intravascular Brachytherapy

血管内放射治疗是防治经皮冠状动脉成形术 (Percutaneous translum inal coronary angioplasty,PTCA)和支架术后发生再狭窄的一项新技术。对其体外和临床实验中的远期疗效和并发症的正确认识 。

Since the introduction of percutaneous transluminal coronary angioplasty, restenosis has remained the most challenging problem facing interventional cardiologist. Intravascular radiation is a feasible and promising adjunctive therapy in restenosis treatment by suppressing both neointimal proliferation and constrictive remodeling, while there are growing concerns about its long-term effects and complications in clinical perspectives as well as dosing and paradoxical stimulation. Current comments on them may well favor the choice of comprehensive treatment protocol for clinicians.
