extracranial การใช้

• Affects medium and small arteries over a diffuse CNS area, without symptomatic extracranial vessel involvement.
• Dilation of these extracranial blood vessels activates the pain receptors in the surrounding nerves, causing a headache.
• Since no frame is needed, some of the radiosurgical concepts can be extented to treat extracranial tumors.
• The paths within the skull are called " intracranial " and the paths outside the skull are called " extracranial ".
• Studies have shown migraine head pain is not accompanied by extracranial vasodilation, but rather only has some mild intracranial vasodilation.
• They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins.
• McLaren s neurosurgery program also works in cooperation with radiation oncology in offering radiosurgery to treat cranial and extracranial cancer and lesions.
• Goldenhar syndrome can be thought of as a particularly severe form of HFM, in which extracranial anomalies are present to some extent.
• Expansion of stereotactic radiotherapy to extracranial lesions is increasing, and includes metastases, liver cancer, lung cancer, pancreatic cancer, etc.
• In place of the stethoscope, a Doppler ultrasound beam measures the blood flow pulsations in intracranial and extracranial segments of the Ophthalmic Artery.
• By some accounts, a large portion ( perhaps the majority ) of CSF is drained through lymphatics associated with extracranial segments of the cranial nerves.
• Instead of intracranial venous problems he described extracranial blockages, and he stated that the location of those obstructions seemed to influence the clinical course of the disease.
• Bypasses created with the help of the ELANA can be to major arteries in the brain, including extracranial to intracranial bypass, or between two arteries in the brain ( intracranial to intracranial ).
• The procedure, known as an extracranial-intracranial brain bypass, involves inserting the superficial temporal artery near the ear into the middle cerebral artery of the brain, according to Dangerfield publicist Kevin Sasaki.
• Intracranial MRA is mostly sufficient to evaluate vertebrobasilar arteries, while extracranial vertebral arteries are better diagnosed using contrast-enhanced MRA, which is less dependent on flow phenomena and more accurate in evaluating stenosis.
• Tuesday's procedure, known as an extracranial-intracranial brain bypass, involved inserting the superficial temporal artery near the ear into the middle cerebral artery of the brain, according to Dangerfield publicist Kevin Sasaki.
• Blood flow in the intracranial OA segment is affected by intracranial pressure, while flow in the extracranial ( intraorbital ) OA segment is influenced by the externally applied pressure ( Pe ) to the eyeball and orbital tissues.
• There are various categories of medical shunts and there are two main categories of shunt used in the treatment of chronic increased intracranial pressure due to cerebrospinal fluid ( CSF ), they are cerebral shunts and lumbar shunts ( extracranial shunts ).
• Many brain areas are not suitable for fMRS studies because they are too small ( like small nuclei in brainstem ) or too close to bone tissue, CSF or extracranial lipids, which could cause inhomogeneity in the voxel and contaminate the spectra.
• As with a sphygmomanometer, a special pressure cuff is used-in this case to compress the tissues surrounding the eyeball and also intraorbital tissues surrounding the extracranial segment of OA . External pressure changes the characteristics of blood flowing from inside the skull cavity into the eye socket.
