Percutaneous recanalisation of coronary chronic total occlusions (CTOs) has proved an efficient and safe treatment option with steadily ascending success rates, especially since the advent and constant refinement of the retrograde approach. Uptake remains low, even though experienced operators have in the last five years reached an unprecedented maturity level, producing success rates in the range of 90 %, clearly comparable to non-occlusive coronary artery disease treatment. Antegrade and retrograde techniques are currently considered complementary components of a CTO procedure, rather than discrete treatment strategies. We report on the case of a successful CTO recanalisation procedure on a young patient with two chronically occluded coronary arteries and a large ischaemic burden. Both CTOs were addressed in the same session employing a range of dedicated CTO recanalisation techniques, without compromising on safety issues related to contrast dye consumption and radiation exposure. A novel drug-eluting stent (DES) with biodegradable polymer was used to treat the lesions.
经皮冠状动脉慢性完全闭塞病变(CTO)再通已被证明是一种有效且安全的治疗选择,成功率稳步上升,特别是自逆向技术问世并不断完善以来。尽管经验丰富的术者在过去五年已达到前所未有的成熟水平,成功率达到90%左右,可与非闭塞性冠状动脉疾病治疗相媲美,但该技术的应用率仍然较低。目前,正向和逆向技术被视为CTO手术的互补组成部分,而非独立的治疗策略。我们报告了一例成功的CTO再通手术病例,患者为年轻男性,有两条冠状动脉慢性闭塞且缺血负荷大。在同一次手术中采用了一系列专门的CTO再通技术处理两条CTO病变,同时不影响与造影剂用量和辐射暴露相关的安全性问题。使用了一种新型的可生物降解聚合物药物洗脱支架(DES)来治疗病变。
