摘要

光學同調斷層掃描（Optical Coherence Tomography, OCT）是以光的同調性為基礎以獲取人體組織與器官的斷層影像，並於1991 年開始應用於冠狀動脈疾病之診斷。2014年七月生物可吸收模架（Bioresorbable Vascular Scaffold, BVS）在台灣開始冠狀動脈介入治療之應用。不同於裸金屬支架（Bare Metal Stent, BMS）與藥物塗層支架（Drug Eluting Stent, DES）會永久留存於人體內，主成分為聚乳酸之生物可吸收模架在置放後二至三年會完全被代謝為二氧化碳與水，僅留下不透X光的標記供術後追蹤之用。本病例報告應用光學同調斷層掃描評估生物可吸收模架的置放效果。

Optical coherence tomography (OCT) is an image modality of obtaining tomographic images of a human organ based on the coherence of light. In vitro observation of the retina and coronary artery was first performed in 1991. Bioresorbable vascular scaffold (BVS) was applied to interventional cardiology in Taiwan in July, 2014. BVS included the pre-mounted polymer poly (L-lactide) scaffold coated with the antipoliferative drug and polymer poly (D, L-lactide). The absence of bare metal stent or drug eluting stent permanent implantation in coronary arteries, BVS would be gradually disappearance in 2-3 years, only radiopaque markers remained. In this case report, OCT was used for evaluating the outcome of BVS implantation.
