Then sending high-pressure _'s general knowledge of lung artery
First, summary
Lung the intersection of artery and high pressure divide into for primary the intersection of lung and artery high pressure and continue the taking place artery high pressure of lung according to cause of disease, artery high pressure of primary lung (primary pulmonary hypertension, PPH) It is one rarely disease, it is clinical define as " can't explaining or lung artery high pressure of reasons unknown " ,Mainly shown as on pathology " Cause the clump lung artery disease (plexogenic pulmonary arteriopathy) " ,Namely plump from the middle level of artery, disease formed to heart or leaning towards damage and necrosis arteritis of hyperplasia of membrane and clump in the disposition,etc.. The cause of disease is not clear so far, think it has illness coming on and relates to such factors as inherent cause, one's own immunity and lung blood vessel shrink at present.
Continuing the taking place artery high pressure of lung far has more common high pressure than the primary lung artery, main part any of respiratory system if angry dish, the intersection of lung and essence, thoracic cages and neural muscle pathological changes can result in continuing the sending artery high pressure of lung. Such as the lung edema, acute to breathe poverty-stricken syndrome, a quality lung disease, tubercle, pneumoconiosis, the intersection of lung and the intersection of thrombus and the intersection of thromboembolism and the intersection of disease and maos of detailed hemangioma, pulmonary vein stop up disease and such as collagenic the intersection of blood vessel and ill, thoracic deformity, Lan - the intersection of Palestinian and the intersection of thunder and syndrome, paralysis nature poliomyelitis Ji
Second, clinical manifestation
Symptom: It is early to usually have no symptom or take clinical manifestation of basic disease such as chronic bronchitis, COPD,etc. as the core, feel uncomfortable only while moving about vigorously; With the rising of the artery pressure of lung, take manifestation not complete of the right heart function as the core in later period, can present whole body symptom such as being tired, unable gradually. Have difficulty in breathing: Symptom regard having difficulty in breathing after the activity as, first publish in most patient, and heart person who discharge reduce and lung keep in touch with the intersection of blood flow and factor such as being imbalance have something to do. The chest aches: Because right heart after-load increases, oxygen consumption increases and it cause the cardiac muscle to be ischemic that the right coronary artery blood supply is reduced etc., often in the activity or emergence when being excited. Dizzy or faint: Because the discharging amount of heart is reduced, the brain organizes the blood supply to reduce suddenly. Often appear while moving about, can happen too while having a rest sometimes. Spit blood: Quantity usually less, can big hemoptysis and death too sometimes. 10% of the patients present Renaud's phenomenon, it causes the sound to be hoarse that the lung artery increased oppresses the recurrent laryngeal nerve.
Physical sign: Physical sign relates to the fact that artery high pressure of lung and right ventricle load increase.
Third, cure the skill inspection
The blood is checked to include liver function test and HIV antibody test and serology are checked, liver cirrhosis, desmosis that HIV is infected with and hides except Israel.
Electrocardiogram: The electrocardiogram can't reflect directly the lung arterial pressure rises, can only play a role in pointing out the right heart and increasing or plump.
The X-ray examination of chest: Brief on X-ray sign of artery high pressure of the lung.
Ultrasonic heart cardon and Doppler's supersound are checked: Can reflect artery high pressure of lung and relevant manifestation.
