Aortoesophageal Fistula Demonstrated by Spiral CT: A Case Report

主動脈食道間瘻管經螺旋性電腦斷層證明:病例報告

摘要


我們報告一位食道癌病人,在做完化學治療及放射治療後,併發了主動脈食道間瘻管。主動脈食道間瘻管在中段食道癌病人是一為人所熟悉的併發症。此類病人在文獻上所報告的個數可謂相當多,然經由電腦斷層攝影所證實者卻為數極少。據我們所知,之前並無文獻發表經由新一代螺旋式電腦斷層所證實的病例。在本例病人,我們使用比傳統少量的對比劑,卻可以在更短的時間內得到正確的診斷,相信螺旋式電腦斷層攝影將來會是診斷此類病例之利器。

並列摘要


An aortoesophageal fistula in a patient with esophageal cancer is reported. Active contrast leakage from the aorta via the fistula tract to the esophagus was well demonstrated with a spiral CT scanner. Spiral CT allows for more rapid data acquisition and less use of contrast material while still providing images of comparatively high quality when measured against those obtained by conventional CT. To the best of our knowledge, only one such case has been reported in the literature. The present case is the first in which this type of aortoesophageal fistula tract been demonstrated by spiral CT.
