A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal.

A laminectomy is a surgical procedure that removes a portion of a vertebra called the lamina, which is the roof of the spinal canal. It is a major spine operation with residual scar tissue and may result in postlaminectomy syndrome.

[2] A myocardial infarction is an ischemic event, or a restriction of blood flow to body tissue, such as by atherothrombosis. [4] Without blood flow to the myocardium, it is deprived of oxygen, causing tissue death and irreversible damage. [5]
