Endovascular biopsy in Takayasu arteritis

Area of Science:

• Cardiology
• Rheumatology
• Vascular Surgery

Background:

• Takayasu arteritis is a chronic inflammatory arteriopathy affecting large vessels like the aorta.
• Disease progression is variable, and assessing current inflammatory activity can be difficult.
• Biochemical markers may not always correlate with clinical presentation, necessitating alternative diagnostic methods.

Purpose of the Study:

• To present a case of endovascular aortic biopsy.
• To evaluate the utility of this minimally invasive technique in detecting active inflammation in the aortic wall in Takayasu arteritis.

Main Methods:

• A case report detailing an endovascular aortic biopsy procedure.
• Histopathological analysis of the aortic wall biopsy specimen to identify inflammatory markers.

Main Results:

• The endovascular aortic biopsy successfully obtained tissue from the aortic wall.
• Histopathology revealed active inflammation, confirming the utility of the biopsy in this specific case.

Conclusions:

• Endovascular aortic biopsy is a feasible approach for evaluating active inflammation in Takayasu arteritis.
• This technique can provide valuable diagnostic information when noninvasive methods are inconclusive.
