Vertebral artery loop formation causing cervical radiculopathy
Vertebral artery loop formation (VALF) is an anatomic variation and uncommon cause of cervical radiculopathy caused by direct compression of the nerve root.
The mechanism of vertebral loop forms and migrates into the intervertebral foramen is unclear. The most common level of occurrence of a tortuous vertebral artery is C3-C4 and C4–C5. The most frequent side of occurrence is on the left.
Incorrect diagnosis of vertebral artery loop formation as disc herniation may lead to a possible injury to the vertebral artery during surgery.
