Decompression (surgery)
In medicine, decompression refers to the removal or repositioning of any structure compressing any other structure. Common examples include decompressive craniectomy (removal of part of the skull to relieve pressure on the brain), and spinal decompression to relieve pressure on nerve root A nerve root (Latin: ''radix nervi'') is the initial segment of a nerve leaving the central nervous system. Nerve roots can be classified as: *cranial nerves, Cranial nerve roots: the initial or proximal segment of one of the twelve pairs of crania ...s.

Decompressive Craniectomy
Decompressive craniectomy ('' crani-'' + '' -ectomy'') is a neurosurgical procedure in which part of the skull is removed to allow a swelling brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke, Chiari Malformation, and other conditions associated with raised intracranial pressure. Use of the surgery is controversial. The procedure evolved from a primitive form of surgery known as trephining or trepanning. The older procedure, while common in prehistoric times, was deprecated in favor of other, less invasive treatments as they were developed; although it was still performed with some frequency prior to the twentieth century, its resurgence in modern form became possible only upon the development of precision cutting tools, cranial drills, and sophisticated post-operative care such as antibiotics. Results of clinical trials Reduction of intracranial pressure Though the procedure is considered a last resort, some evidence ...

Spinal Decompression
Spinal decompression is the relief of pressure on the spinal cord or on one or more compressed nerve roots passing through or exiting the spinal column. Decompression of the spinal neural elements is a key component in treating spinal radiculopathy, myelopathy and claudication. Surgical methods Decompression of nerve roots When a single spinal nerve root is compressed, the resulting clinical outcome is termed radiculopathy, and is usually labeled according to the specific nerve root compressed (hence compression of the nerve root exiting the spinal column below the left-sided pedicle of the L5 vertebra will be diagnosed as "left L5 radiculopathy"). Microdiscectomy (or microdecompression) is a minimally invasive surgical procedure in which a portion of a herniated nucleus pulposus is removed by way of a surgical instrument. The purpose of this procedure is to relieve the pressure and reduce the local inflammatory reaction around a nerve root, caused by the herniated nucleus pulpos ...

Nerve Root
A nerve root (Latin: ''radix nervi'') is the initial segment of a nerve leaving the central nervous system. Nerve roots can be classified as: *Cranial nerve roots: the initial or proximal segment of one of the twelve pairs of cranial nerves leaving the central nervous system from the brain stem or the highest levels of the spinal cord. *Spinal nerve roots: the initial or proximal segment of one of the thirty-one pairs of spinal nerves leaving the central nervous system from the spinal cord. Each spinal nerve is formed by the union of a sensory dorsal root and a motor ventral root, meaning that there are sixty-two dorsal/ventral root pairs, and therefore one hundred and twenty-four nerve roots in total, each of which stems from a bundle of nerve rootlets (or root filaments). Cranial nerve roots Cranial nerves originate directly from the brain's surface: two from the cerebrum and the ten others from the brain stem. Cranial roots differ from spinal roots: some of these roots do not se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Procedures And Techniques
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of the surgeon, the surgeon's assistant, an anaesthetist, a circulating nurse and a surgical technologist. Surgery usually spa ...
