AbstractThe aim of this National Diagnostic and Care Protocol (PNDS) is to explain to the professionals involved the current optimal diagnosis and therapeutic management and care approach for a patient with Takayasu’s arteritis. Its purpose is to optimize and harmonize the management and follow-up of this rare disease throughout the country. It also identifies pharmaceutical specialties used in an indication not provided for in the Marketing Authorization, as well as the specialties, products or services necessary for the care of patients but not usually paid for or reimbursed.
Diagnosis of non-specific aorto-arteritis (NSAA, Takaysu's arteritis) is typically based on clinical and investigational parameters. We report here about two patients with clinically suspected diagnosis of a Takayasu's arteritis already under anti-inflammatory therapy in whom percutaneous transluminal atherectomy of subclavian and axillary artery stenoses was performed to relief the patients from symptoms – intermittent dyspraxia of the arms – and to verify the clinical diagnosis by histology. In the first case aorto-arteritis could be histologically confirmed through the analysis of plaque material including media structures excised from the subclavian and axillary arteries using a new device for atherectomy. The biopsy showed diffuse inflammation and granulomatous lesions with giant cells typically for Takayasu's disease. In the second patient, biopsy showed no acute or chronic inflammatory signs but only atherosclerotic lesions. Percutaneous transluminal atherectomy is therefore not only an interventional but also a diagnostic tool and should be used in every case of interventional therapy of suspected aorto-arteritis to make the clinical diagnosis and as a major consequence the initiation of an aggressive anti-inflammatory medical therapy more reliable.
