Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke (MELAS) syndrome is a progressive multisystemic neurodegenerative disorder. MELAS syndrome impairs oxidative phosphorylation and predisposes patients to lactic acidosis, particularly under metabolic stress. We report 2 siblings with MELAS-associated idiopathic scoliosis who underwent posterior spinal instrumented fusion with measures taken to minimise anaesthetic and surgical stress, blood loss, and operating time.
To evaluate the perioperative complications associated with surgical correction in neuromuscular scoliosis and to identify the risk factors associated with these complications.
