Atherosclerosis and fibromuscular
dysplasia are the major causes of renal artery stenosis.
Investigations for fibromuscular
dysplasia, thyrotoxicosis, HIV and pregnancy were all negative.
The vaginal epithelium was dissected off of the underlying fibromuscular
connective tissue to create a U-flap.
Risk factors associated with the development of TRAAs are fibromuscular
dysplasia, atherosclerosis, and vasculitis such as Marfan syndrome, Takayasu, or Behcet disease (6).
DAs of the ICA can occur spontaneously or in association with various etiological factors including craniomaxillofacial trauma, head and neck surgeries, hyperextension or hyperflexion of the neck, fibromuscular
dysplasia, and connective tissue disorders such as Ehlers-Danlos and Marfan syndromes.
During evaluating for ACD, we should differentiate several entities including PA aneurysm, PA entrapment, peripheral artery disease, Baker's cyst, and fibromuscular
dysplasia., For this, magnetic resonance angiography and CTA are helpful as in our case.,,
Prostate is a fibromuscular
stroma  of size about 3 cm x 3.5 cm.
further contributed that necrosis, luminal narrowing, fibrosis, loss of medial elastic fibres or smooth muscle and fibromuscular
hyperplasia may also be evident.
Other causes like aortic dissection8, fibromuscular
dysplasia9, post radiation vasculopathy10 can also present like transient cerebral arteriopathy (TCA).
While in 30 per cent cases, physical stress (in 10 per cent this was lifting more than 23 kg) occurred before SCAD, the most common predisposing condition was fibromuscular
dysplasia (40 per cent) which causes abnormal cell development in the arteries and can lead to narrowing (stenosis), aneurysms, or tears (dissections).
Less frequent causes of exclusion included arterial aneurysms (n = 2), fibromuscular
dysplasia (n = 1), atherosclerotic plaque at renal arterial ostium (n = 1), multiple renal artery aneurysms suggesting polyarteritis nodosa (n = 1), arterio-venous malformation (n = 1), and duplicated inferior vena cava (n = 1).
