The early symptoms of arterial entrapment are mainly pain, and secondary symptoms due to ischemia in the area innervated by the corresponding vessel.
The majority of acute onset of arterial sandwich, mainly in the large arteries, the middle artery wall of the three-layer structure, the inner membrane appeared rupture, along the middle of the membrane continues to tear in the direction of or reverse, blood into the inner membrane and the outer membrane between the formation of sandwich biscuit-like structural changes, the arterial sandwich.
The danger of a sandwich is that it may rupture and hemorrhage at any time due to increased pressure within the vessel, which the tunica albuginea cannot withstand.
A part of the vascular sandwich due to the sandwich-like structure is too large, pressure to the original lumen occlusion, ischemia and necrosis of the distal end of the blood vessel, dysfunction, pain, etc..
The most serious type of arterial entrapment is aortic entrapment, more than 80% of patients will be accompanied by high blood pressure, tachycardia, the patient is irritable, sweating, the onset of the onset of severe tear-like, knife-like pain, with the extension of the scope of the tear, the scope of the pain increases, the short period of time the blood pressure is not well controlled, it will rupture the blood vessel and die.
Discovered with arterial entrapment, regardless of location, may lead to serious consequences, it is recommended that the earliest possible regular specialist consultation and treatment.
