Publication date: October 2016 Source:Hong Kong Journal of Nephrology, Volume 19 Author(s): Ho Kwan Ken Sin, Samuel Ka Shun Fung, Hon Lok Tang, Au Cheuk, William Lee, Ka Fai Yim, Ka Yan Poon, Lok Yan Wong, Hiu Man Cheng We herein present a case of an intrarenal pseudoaneurysm developing 2 weeks after renal transplantation. The patient presented with hemorrhagic shock. Computed tomography confirmed an intrarenal pseudoaneurysm with extravasation of contrast and a large surrounding hematoma. Angiography confirmed the pseudoaneurysm, and embolization of the segmental graft renal artery was performed. In view of the uncertain etiology and the possibility of a mycotic pseudoaneurysm, we administered empiric antimicrobial therapy. The clinical course, investigations, and management are described. Finally, a review of the literature regarding post-transplantation pseudoaneurysms is presented. 以下是一宗於移植後 2 週出現的腎內僞動脈瘤個案，患者以出血性休克表現。當時為其安排緊急電腦斷層攝影 (CT)，發現有一個腎內僞動脈瘤，並呈現顯影劑溢出現象，且被一大型血腫圍繞。緊急血管攝影證實為植入腎之僞動脈瘤，同時我們對涉及的節段性動脈予以栓塞處置。基於病因並不明確，而且不能排除黴菌性僞動脈瘤的可能性，因此我們實施了經驗性抗微生物學療法。在本文中，我們描述了本個案的臨床歷程、相關檢查及後續處置，並...
