Difference between carotid artery and vertebral artery

The main differences between carotid artery and vertebral artery include different positions, different blood supply areas, different structural characteristics, different disease manifestations, different examination methods and different clinical significance. 2. Different carotid arteries supply blood to the anterior part of the brain, eyes and part of the face. Vertebral arteries supply the posterior part of the brain, cerebellum and brain stem. They provide sufficient blood for the brain to maintain normal function and metabolism. 3. Structural characteristics Different carotid arteries are relatively thick in diameter, and their branches include internal carotid artery and external carotid artery. Vertebral artery is relatively thin, and the journey is long, passing through the cervical transverse foramen. 4. Different disease manifestations Carotid artery lesions such as stenosis, plaque formation, etc., may lead to cerebral ischemia symptoms, such as dizziness, transient amaurosis, limb weakness, etc., severe cases can cause cerebral infarction; Vertebral artery lesions can cause dizziness, balance disorders, blurred vision and other posterior circulation ischemia manifestations. 5. Different examination methods For carotid artery, common examination methods include carotid artery ultrasound, carotid angiography, etc.; for vertebral artery examination, transcranial Doppler ultrasound, vertebral angiography, etc. The diagnosis and treatment of vertebral artery lesions are also crucial to maintaining the stability of the posterior circulation. The carotid artery and vertebral artery are different in location, blood supply area, structural characteristics, disease manifestations, examination methods and clinical significance. Understanding these differences helps Accurate diagnosis and treatment of related diseases.
