Arteritis de células gigantes: compromiso extenso de la aorta y grandes ramas demostrado por tomografía por emisión de positrones. Caso clínico / Extensive arterial involvement in giant cell arteritis: report of one case

Large vessel vasculitis and particularly Temporal Arteritis are systemic diseases that may affect the aorta and its major branches, mainly involving extra cranial branches of the carotid artery. We report a 72-year-old man presenting with weight loss, fever and malaise. Positron emission computed tomography (PET CT) showed an extensive inflammation of the aorta and its major branches. Temporal artery biopsy confirmed the presence of vasculitis with granulomas. Treatment with a high dose of steroids had an excellent clinical response. This case underscores the utility of PET CT in the assessment of this disease.

Vasculitis de grandes vasos en paciente con vasculitis ANCA (+): Caso clínico / Large vessel involvement in ANCA-associated vasculitis: Report of one case

Pauci-immune glomerulonephritis in systemic vasculitides usually have anti-neuthrophil cytoplasmic antibodies (ANCA). However, vasculitides of large vessels such as Takayasu’s and giant cell (temporal) arteritis do not. Exceptionally ANCA(+) small vessel vasculitides are associated with large vessel vasculitis. It may be a coincidence or both vasculitides have a common pathogenesis. We report a 30 years old woman on hemodialysis due to a chronic glomerulonephritis ANCA(+) diagnosed nine years ago. Eight years later, she presented with an aortitis with severe stenosis of distal aorta and vasculitis of left subclavian artery. She was treated with adrenal steroids and cyclophosphamide. During the ensuing five years she has been stable and without signs of reactivation of the disease.

Stanford Type A Aortic Dissection Secondary to Infectious Aortitis: A Case Report

Nowadays, infectious aortitis has become a rare disease thanks to antibiotics, but remains life-threatening. We present a case of a patient with acupuncture-induced infectious aortitis leading to aortic dissection. Chest computed-tomogram scan revealed Stanford type A dissection with pericardial effusion. Under the impression of an impending rupture, emergent surgery was performed. During surgery, infectious aortitis was identified incidentally, so she underwent resection of the infected aorta including surrounding tissues. Then the ascending aorta and hemi-arch were replaced with a prosthetic graft as an in situ fashion. The resected tissue and blood cultures revealed Staphylococcus aureus, so prolonged antibiotherapy was prescribed.
