subclavian plexus |

subclavian steal |
Obstruction of the subclavian artery proximal to the origin of the vertebral artery; blood flow through the vertebral artery is reversed and the subclavian artery thus "steals" cerebral blood, causing symptoms of vertebrobasilar insufficiency (subclavian steal syndrome); manifest during vigorous use of an upper extremity. (05 Mar 2000) |
subclavian steal syndrome |
<syndrome> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome is characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |
subclavian sulcus |
A groove on the inferior surface of the body of the clavicle to which is attached the subclavius muscle. Synonym: sulcus musculi subclavii, subclavian sulcus, sulcus subclavianus. (05 Mar 2000) |
subclavian triangle |
The triangle bounded by the clavicle, the omohyoid muscle, and the sternocleidomastoid muscle; it contains the subclavian artery and vein. Synonym: fossa supraclavicularis major, trigonum omoclaviculare, greater supraclavicular fossa, omoclavicular triangle, subclavian triangle. (05 Mar 2000) |
subclavian vein |
<anatomy, vein> The continuation of the axillary vein which follows the subclavian artery and then joins the internal jugular vein to form the brachiocephalic vein. (12 Dec 1998) |
subclavicular |
Pertaining to the region beneath the clavicle. (05 Mar 2000) |
subclavius |
<anatomy, muscle> Origin, first costal cartilage; insertion, inferior surface of acromial end of clavicle; action, fixes clavicle or elevates first rib; nerve supply, subclavian from brachial plexus. Synonym: musculus subclavius, subclavian muscle. (05 Mar 2000) |
subclinical |
Without clinical manifestations, said of the early stage of an infection or other disease or abnormality before symptoms and signs become apparent or detectable by clinical examination or laboratory tests or of a very mild form of an infection or other disease or abnormality. (18 Nov 1997) |
subclinical diabetes |
A form of diabetes mellitus that is clinically evident only under certain circumstances, such as pregnancy or extreme stress; persons so afflicted may, in time, manifest more severe forms of the disease. (05 Mar 2000) |
subclinical disease |
An illness that stays below the surface of clinical detection. A subclinical disease has no recognizable clinical findings. As distinct from a clinical disease which has clinical signs and symptoms that can be recognised. Many diseases are subclinical before surfacing as clinical diseases. For examples: diabetes, hypothyroidism, rheumatoid arthritis. (12 Dec 1998) |

A seizure detected by EEG, which has no clinical correlate, i.e., an EEG seizure alone or an electrical seizure alone. Synonym: electrographic seizure. (05 Mar 2000) |
