Takayasu Arteritis

Takayasu Arteritis is a rare condition that causes inflammation of the large blood vessels, especially the aorta and its main branches. This inflammation can lead to narrowing or blockage of these vessels, which affects blood flow to different parts of the body. People with this condition may experience symptoms like weak pulses, arm or leg pain, and high blood pressure due to reduced blood supply. It mainly affects young women and can cause serious problems if not diagnosed and managed properly. The disease impacts the circulatory system and can lead to complications such as stroke or heart failure if the arteries supplying the heart or brain are involved.

Takayasu Arteritis is a chronic, large-vessel vasculitis characterized by granulomatous inflammation of the aorta and its major branches, leading to arterial wall thickening, stenosis, occlusion, or aneurysm formation. The exact cause is unknown but is thought to involve an autoimmune mechanism with T-cell mediated injury to the vessel wall. It predominantly affects young women under 40 years old and is more common in Asian populations. The inflammation results in vascular ischemia and symptoms related to reduced blood flow such as claudication, absent or diminished pulses, and blood pressure discrepancies between limbs. Histologically, there is granulomatous inflammation with giant cells and intimal proliferation. The disease can cause serious complications including hypertension, aortic regurgitation, and stroke due to involvement of the aortic arch branches and renal arteries.
