Shrinkage of a Giant Type-B Dissecting Aneurysm Treated by Complete False Lumen Occlusion 20 Years after Presentation: A Case Report.

Abstract

In this study, we report the case of a 47-year-old female who presented with extensive acute type IIIb aortic dissection and cerebral infarction. At 69 years of age, dilatation of the descending aorta was noted to be more than 70 mm with compression of the left atrium. We performed endovascular repair with distal false lumen occlusion. However, further dilatation of the descending aorta with false lumen flow from the re-entry of the common carotid artery was detected. She subsequently underwent additional proximal false lumen occlusion by embolization at the aortic arch. A year later, as per her computed tomography angiography findings, appreciable shrinkage of the descending aorta without endoleakage was observed.
