Record 3 2017-10-25

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Musculoskeletal System
DEF

A test for thoracic outlet syndrome : with the patient in a sitting position, his hands resting on thighs, the examiner palpates both radial pulses as the patient rapidly fills his lungs by deep inspiration and, holding his breath, hyperextends his neck and turns his head toward the affected side. If the radial pulse on that side is decidedly or completely obliterated, the result is considered positive.

OBS

Adson’s maneuver: term recommended by the Medical Signs and Symptoms Committee.

DEF

Manœuvre qui provoque la diminution ou la disparition du pouls radial, en cas de compression de l'artère sous-clavière au niveau du défilé costo-claviculaire; cette manœuvre est réalisée par l'extension et la rotation de la tête du côté de la sténose, au cours d'une inspiration profonde.

Record 4 2009-08-19

English

Subject field(s)
  • Respiratory System
CONT

Forced inspiration is caused by the contraction of muscles in the upper chest, such as the sternocleidomastoids & scalenes. These muscles pull the chest up and out even more, further decreasing the intrapleural pressure so that even more air will rush into the lungs to fill the void.

CONT

In a healthy subject everything works together to create large flows during a forced inspiration : 1 The greater the inspiratory force applied, the lower the alveolar pressure relative to pressure at the mouth, and the larger the flow into the lung. 2 During a forced inspiration the(subatmospheric) pleural pressure outside intrathoracic airways is lower than bronchial pressure. The pressure difference is largest at the thoracic outlet and smallest in small intrapulmonary airways. Hence large intrathoracic airways... are subjected to a considerable distending force, and this helps in generating high inspiratory flows.

French

Domaine(s)
  • Appareil respiratoire
CONT

Le plus important [des muscles inspiratoires] est le diaphragme. [...] Dans l'inspiration rentrent également en ligne de compte les muscles intercostaux externes qui renforcent le mouvement de soulèvement des côtes et du sternum. Les muscles sterno-cléïdo-mastoïdiens n'ont un rôle que dans l'inspiration forcée; de même que les muscles scalènes.

CONT

L'inspiration forcée et l'expiration forcée permettent au système respiratoire de s'adapter aux différents besoins physiologiques de l'ensemble des cellules dans des situations variables. Par exemple, un marathonien qui inspire profondément et utilise complètement sa réserve inspiratoire et la moitié de sa réserve expiratoire voit son volume inspiratoire passer de 500 ml (volume courant) à 4200 ml.

Record 5 2009-02-17

English

Subject field(s)
  • Nervous System
DEF

Any of a variety of neurovascular syndromes resulting from compression of the subclavian artery, the brachial plexus nerve trunks, or less often the axillary vein or subclavian vein, by thoracic outlet abnormalities such as a drooping shoulder girdle, a cervical rib or fibrous band, an abnormal first rib, or occasionally compression of the edge of the scalenus anterior muscle. Continual hyperabduction of the arm may cause another variety(hyperabductions). Arterial compression leads to ischemia, paresthesias, numbness, and weakness of the affected arm, sometimes with Raynaud's phenomenon of the arm. Nerve compression causes atrophy and weakness of the muscles of the hand and, in advanced cases, of the forearm, with pain and sensory disturbances in the arm. Venous obstruction usually takes the form of the Paget-Schroetter syndrome.

French

Domaine(s)
  • Système nerveux
DEF

Ensemble des troubles provoqués par la compression des éléments du paquet vasculonerveux du membre supérieur au cours de son trajet entre l'orifice supérieur du thorax et la base du creux axillaire.

Key term(s)
  • syndrome de traversée throco-cervico-brachiale
  • syndrome de traversée thoraco-brachiale
  • syndrome du défilé thoracobrachial

Spanish

Campo(s) temático(s)
  • Sistema nervioso
DEF

Condición causada por la compresión de elementos neurovasculares a nivel del opérculo torácico o en la zona de transición cervicobraquial.

OBS

Se caracteriza por la aparición de molestias al realizar actividades que impliquen levantar los brazos.
