Artery _'s symptom of a narrow differential diagnosis of the lung
Differential diagnosis: Simple slight lung narrow to need, distinguish the former lung blood volume reduces the latter to increase with ventricular septal defect in petal in artery, and there is difference in noise position and property, the former's noise assumes diamond in shape in the heart sound picture for injection, the latter's noise takes the whole systolic phase, always type present in the heart sound picture. The heart conduit can assist to distinguish to check, it should be distinguished with Fallow's block of four that narrow with the livid purple severe lung artery one, the former livid purple to appear relatively late, lung the intersection of artery and the intersection of district and the intersection of systolic phase and noise better the 2nd heart sound split, but relatively weak, often there is lung artery section that is expanded on the X line.
1.Narrow and other cardiovascular and odd-shaped differentiation of lung artery
( 1) Distinguish with primary lung arteriectasis: It is distinguished that primary lung arteriectasis and slight lung artery one are narrow and extremely difficult. The former can have a slight early injection systolic phase noise, but not so coarse as the latter and seldom with trembling. Electrocardiogram and vectorial electrocardiogram normal, have right plump to brief on, have the intersection of lung and petal narrow artery room. Pursue to be distinguished, need the right heart conduit of conduct to check if necessary and the cardiovascular vessel radiography is checked in order to make a definite diagnosis of in the supersound aroused in interest.
( 2) Distinguish with atrial septal defect: The systolic phase noise of the left reason of patient's brestbone of atrial septal defect is not as loud and coarse as narrow patient of lung artery, and not common with trembling; Lung the intersection of artery and the second sound split while being fixed, split getting narrow as the intersection of lung and artery obvious the intersection of brestbone and left predestination often have a medium noise of relaxation.
( 3) Distinguish with ventricular septal defect: The left reason of patient's brestbone of ventricular septal defect has very loud the whole systolic phase noise and with trembling, have systolic phase spray sound, X-ray block show left room to be left room old, lung blood increase, heart electricity illustrationally show pairs of plump room and the right room is plump alone; Pursue to be distinguished in the supersound aroused in interest.
( 4) Close the phase locking to distinguish with the intact lung artery of interventricular septum: Should pay attention to distinguishing to the neonate or little baby patient the two two can all be livid purple and in heart failure and the lung blood is reduced. The lung artery of the most common type is locked to a patient, the right room often develops badly, and there is not obvious cardiac dilatation, electrocardiogram it presents left rooms to be plump, two-dimentional supersound can distinguish, have the intersection of alternative and the intersection of film and the intersection of cardiovascular vessel and radiography can must be distinguished and locked with seriously narrow only tentatively while being aroused in interest to pursue.
( 5) Shift down the deformity to distinguish with the tricuspid valve: Typical physical physical sign and electrocardiogram finding can be distinguished.
2.The simple lung artery is narrow and the lung artery is narrow amalgamate other odd-shaped differentiation
( 1) Narrow with the lung artery one to amalgamate small-scale ventricular septal defect to distinguish: This type person part narrow to see because of ventricular septal defect being relatively little more with funnel, the pressure of right room can be higher than the pressure of left room. Precise to distinguish that needs to depend on the radiography of cardiovascular vessel
( 2) Narrow with the lung artery to amalgamates the artery conduit and has not closed and distinguished: This kind of patient's clinical manifestation is like the artery conduit and has not closed but has had a loud spraying sound with systolic phase the noise and one that tremble above the left reason of brestbone, have the intersection of right ventricle and plump electrocardiogram brief on, amalgamate the intersection of lung and petal narrow artery. Can take advantage of the supersound aroused in interest to pursue as a means of distinguishing.
( 3) Distinguish with Noonan syndrome: This disease patient 50% can amalgamate congenital heart disease, and the most common amalgamation deformity is narrow for the lung artery one, often bad type for the artery development of lung. In addition, Shang Ke amalgamates atrial septal defect and left room myocardiumly patient of disease, this disease has special face, the stature is short, wing neck, blepharoptosis of eyes,etc., and gonad functions can be distinguished low.
