The most frequently observed problems related to a cerebral arteriovenous malformation (AVM) are headaches and seizures, cranial nerve afflictions including pinched nerve and palsy, [2] [3] backaches, neckaches, and nausea from coagulated blood that has made its way down to be dissolved in the cerebrospinal fluid.
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

Other symptoms include skin ulcers, bluish skin, cold skin, or abnormal nail and hair growth in the affected leg. [3] Complications may include an infection or tissue death, which may require amputation; coronary artery disease; or stroke. [4] Up to 50% of people with PAD do not have symptoms.
