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,並指出我們在治療上所遭遇到的困難。最後,我們對移植後僞動脈瘤的相關文獻作出了回顧
