Abstract:
We herein present the first reported case of reversible cerebral vasoconstriction syndrome (RCVS) in Takayasu's arteritis (TA), in a patient with severe thunderclap headache and generalized tonic-clonic seizure. Magnetic resonance imaging and angiography revealed posterior reversible encephalopathy syndrome, followed by severe vasoconstriction in multiple arteries. RCVS should be included in the differential diagnosis of thunderclap headache attacks with radiologic intracranial vascular abnormalities in connective tissue diseases, including TA.

Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
