ABSTRACT
A Type IV endoleak is a very rare complication following endovascular aneurysm repair (EVAR) and differential diagnosis can be difficult. Reported here is a case that showed the development of a Type IV endoleak after an EVAR procedure, for which a novel software was useful to differentiate that from Type I based on visual confirmation. The 89-year-old man was diagnosed with a large abdominal aortic aneurysm, sized 70 mm, as shown by computed tomography (CT). EVAR was performed in a routine fashion using an Endurant II stent graft. Postoperative CT revealed a massive endoleak around the neck that was difficult to differentiate between Types I and IV. The use of the novel software Viewtify (SCIEMENT, Inc., Tokyo, Japan) to visualize the endoleak with surrounding tissues as real-time three-dimensional computer graphics (3DCG) resulted in confirmation that the endoleak was not from the proximal end but rather the stent graft body. CT findings obtained one week later showed that the endoleak had diminished and no additional procedures were needed. Following a diagnosis of endoleak after EVAR, images viewed with Viewtify helped to confirm the appropriate diagnosis. This novel software was found useful to clarify the position and mechanism of a Type IV endoleak.
