Abstract:

Objective

To investigate the characteristics of pulmonary artery involvement in Takayasu′s arteritis by conventional ultrasound and contrast-enhanced ultrasound and its value in the diagnosis of the disease.

Methods

The findings of echocardiography, peripheral vascular ultrasound, and contrast enhanced ultrasound of the heart and peripheral vessels were reviewed and analyzed in 5 patients with pulmonary artery involvement in Takayasu′s arteritis.

Results

The main features of conventional ultrasound in 5 patients were as follows: tricuspid regurgitation (4/5), pulmonary valvular regurgitation (2/5), pulmonary arterial hypertension (3/5), the diameter of the left or right pulmonary artery was decreased (3/5), the wall of the left or right pulmonary artery was thickened and the echogenicities were decreased (3/5), the peripheral vessels outside the pulmonary artery were invaded (5/5). The main features of contrast-enhanced ultrasound in 5 patients were as follows: the diameter of the left or right pulmonary arteries showed low or no enhancement (4/4), thickened vascular walls were markedly or slightly enhanced (4/5), thickened vascular walls were not enhanced (1/5).

Conclusions

The ultrasonic manifestations of pulmonary artery involvement in Takayasu′s arteritis have some characteristics. Conventional plus and contrast-enhanced ultrasound combined with clinical manifestations and peripheral vascular findings will be helpful in the diagnosis of pulmonary arteries involvement in Takayasu′s arteritis.
