If acute hepatic artery thrombosis occurs after liver transplantation, then retransplantation with a new liver may be necessary.However, chronic hepatic artery thrombosis may not require therapy, as the gradual development of additional blood vessels (collateral circulation) may be adequate for the metabolic needs of the liver. Prognosis
The development of hepatic artery thrombosis soon after liver transplantation is associated with higher risk of death (mortality) and transplanted liver failure (graft loss). Epidemiology
Hepatic artery thrombosis is the most common complication that occurs after liver transplantation. Hepatic artery thrombosis may also occur after other surgeries. Hepatic artery thrombosis and primary non-function are the two most common reason that a transplanted liver fails to work (graft failure). Among people who receive liver transplants, smoking tobacco increases the risk of hepatic artery thrombosis. == References ==
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury. It is characterized by loss of motion and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to  major injury to the central corticospinal tract of the spinal cord. The syndrome is more common in people over the age of 50 because osteoarthritis in the neck region causes weakening of the vertebrae. CCS most frequently occurs among older persons with cervical spondylosis, however, it also may occur in younger individuals.CCS is the most common incomplete spinal cord injury syndrome. It accounts for approximately 9% of traumatic SCIs. After an incomplete injury, the brain still has the capacity to send and receive some signals below the site of injury. Sending and receiving of signals to and from parts of the body is reduced, not entirely blocked. CCS gives a greater motor loss in the upper limbs than in the lower limbs, with variable sensory loss. It was first described by Schneider in 1954. It is generally associated with favorable prognosis for some degree of neurological and functional recovery. However, factors such as age, preexisting conditions, and extent of injury will affect the recovery process. Presentation
CCS is characterized by disproportionately greater motor impairment in upper compared to lower extremities, and variable degree of sensory loss below the level of injury in combination with bladder dysfunction and urinary retention.
