Sonographic Evaluation of the Progression of Takayasu’s Arteritis

Abstract

Takayasu’s arteritis (TA) is a rare nonspecific inflammatory disease of unknown cause predominantly affecting the aorta and its main branches, coronary arteries, and pulmonary arteries of young females. Diagnosis of TA is typically achieved through computed tomography angiography (CTA) or magnetic resonance angiography (MRA), with sonography often used as a tool for surveillance of disease progression following diagnosis. A case of previously diagnosed TA is presented that demonstrates the effective use of sonography to monitor the progression of the disease with serial examination. The use of CTA and MRA allowed for accurate initial diagnosis, whereas sonography proved to be an effective diagnostic surveillance tool for proper tracking of the disease and its clinical manifestations. Increased sonographer awareness of TA including the clinical manifestations and sonographic characteristics associated with progression of the disease can improve patient outcomes in this potentially life-threatening disease.
