HYPOPERFUSION [5 records]

Record 1 2024-01-12

English

Subject field(s)
  • Symptoms (Medicine)
  • Vessels (Medicine)
DEF

The stage before fainting that involves experiencing fainting symptoms without loss of consciousness.

CONT

Presyncope or near-syncope is often ill-defined and may have different meanings to different providers but denotes near fainting or a prodrome of syncope. The most uniform definition is ’’feeling like one was going to pass out but without actual loss of consciousness. ’’Near syncope can last for seconds to minutes. Symptoms may be accompanied by a feeling of lightheadedness, general weakness, warmth, diaphoresis, nausea, palpitations or blurry vision. Although often perceived as more benign than syncope, data suggest that both the pathophysiology(cerebral hypoperfusion) and outcomes of near syncope mimic those of syncope.

CONT

The patient with microcirculation disturbance is not able to achieve an oxygen demand-supply balance, leading to inadequate oxygen use by the cell—a condition known as cellular hypoperfusion.

Domaine(s)
  • Symptômes (Médecine)
  • Vaisseaux (Médecine)
CONT

Les manifestations biologiques d'état de choc (ex : acidose métabolique, hyperglycémie) sont des signes indirects et tardifs témoignant d'une hypoperfusion cellulaire plus ou moins importante.

CONT

Lactic acidosis is a form of metabolic acidosis that begins when a person overproduces or underutilizes lactic acid, and their body is not able to adjust to these changes.... There are two types of lactic acidosis, Type A and Type B : Type A lactic acidosis is caused by tissue hypoperfusion resulting from hypovolemia, cardiac failure, sepsis, or cardiopulmonary arrest[;] Type B lactic acidosis is caused by impairment of cellular functioning and localized areas of tissue hypoperfusion.

CONT

L'acidose lactique est une acidose métabolique organique due à une accumulation d'acide lactique par augmentation de sa production ou diminution de son utilisation.

OBS

acidose lactique : Le terme «acidose lactique» est parfois utilisé pour désigner l'acidose lactique congénitale.

Record 5 1994-12-13

English

Subject field(s)
  • Vessels (Medicine)
CONT

We analyzed the relationship between abnormal perfusion and morphological changes on follow-up CT scans. Patients were divided into infarct and periinfarct regions. Results : Among a total of 30 infarct regions, 3 lesions studied at 1. 5, 2. 5 and 5 hours after the ictus showed local hyperperfusion suggestive of early postischemic hyperemia, while the other 27 lesions demonstrated local hypoperfusion.

French

Domaine(s)
  • Vaisseaux (Médecine)
CONT

Chez 6 malades droitiers présentant des troubles schizophréniques, il a été découvert par les méthodes d'imagerie morphologique une atrophie corticale localisée temporale gauche, qui s'accompagnait à la tomoscintigraphie d'une hypoperfusion de même siège, souvent plus étendue.
