Coronary artery aneurysm with associated fistula is a rare condition. The complete anatomical delineation of this condition can be achieved with multi-detector computed tomography, which has advantages over echocardiogram and catheter angiography because of its ability to show the fistula separate from the surrounding cardiovascular structures, along with any aneurysm or obstruction along its course. Thus, multi-detector computed tomography may be preferred as the initial non-invasive imaging technique for characterisation of these rare congenital anomalies, and may be considered an alternative to conventional coronary angiography for follow-up studies because of its relative non-invasive nature.

冠狀動脈瘤合併瘻管：經多層斷層CT冠狀動脈造影檢測的罕見病症
曾慧勤、李子飛
冠狀動脈瘤合併瘻管是一種罕見病症。由於多層電腦斷層掃描可完整地顯示其解剖結構，所以它比超聲心動圖和導管造影優勝。而且它可以把瘻管從包繞的心血管結構中分離顯示，以及顯示沿瘻管經行的任何動脈瘤或阻塞病變。因此，作為這類罕見先天性異常病變的初步無創性影像檢察，多層電腦斷層掃描或被優先採用。基於該技術的無創性，它或可取代傳統冠脈造影以作病況跟進。
