Abstract
The patient was a 72-year-old man with a history of kidney transplantation and long-term administration of methylprednisolone and immunosuppressants who underwent resection and reconstruction of a brachial artery aneurysm. A pathological examination confirmed mycobacteria, indicating an inflammatory aneurysm with amyloid kappa light chain deposition caused by intracellular nontuberculous mycobacterium. To our knowledge, this is the first demonstration of an inflammatory brachial artery aneurysm with amyloidosis caused by nontuberculous mycobacterial infection. When a nontuberculous mycobacterial infection is diagnosed, it is important to take into account the potential development of aneurysms at locations outside of the lungs.
期刊介绍:
Journal of Vascular Surgery Cases and Innovative Techniques is a surgical journal dedicated to publishing peer review high quality case reports, vascular images and innovative techniques related to all aspects of arterial, venous, and lymphatic diseases and disorders, including vascular trauma, malformations, wound care and the placement and maintenance of arterio-venous dialysis accesses with an emphasis on the practicing clinician. The Journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals involved with the management of patients with the entire spectrum of vascular disorders.
