What kind of _ general knowledge of disease does lung artery lock and amalgamate ventricular septal defect
First, what kind of disease does lung artery lock and amalgamate ventricular septal defect?
The lung artery is locked to amalgamate ventricular septal defect (PA-VSD) Broad sense define as follows: It is a group of inborn heart malformations, comprising: A of continuity of tube of letting wholeheartedly from room to lung artery cuts off and there is no blood flow to pass; Shown as one's own lung artery part or totally scarce like. It is a rare, complicated congenital heart disease that the lung artery is locked to amalgamate ventricular septal defect, treat success rate to be relatively low in the past, through medical technical development in recent years, can implement person who condone first now surgery guarantee lung artery lock, amalgamate life, infant of ventricular septal defect, the by the time suitable opportunity carries on the lung artery and locks and amalgamates the ventricular septal defect effecting a radical cure operation. Can improve the lung artery and lock the success rate which amalgamates ventricular septal defect treatment so.
Companion's ventricular septal defect is a group of complicated and various congenital heart diseases that the lung artery is locked, it is defined as the ventricle and there are pipelines that are connected among the lung artery, there is no blood to circulate, defect that there is the interventricular septum. Classify as the perpetuity artery being type or getting false artery, was in the past, had not used yet now. Also someone thinks the lung artery and locks companion's ventricular septal defect it is the most serious type of of Fallow's block of four, so called Fallow's block of four and accompany the lung artery to be locked.
Second, how to carry on the lung artery and lock and amalgamate ventricular septal defect and diagnose to distinguish?
Most lung arteries are locked in the heart of companion's ventricular septal defect the structural change is similar to Fallow's disease of block of four, especially lung artery do fiber locked to have when the pieces of Suo always. But lung artery lock companion, watch lung artery always do or the intersection of fiber and pieces of Suo often in the the intersection of ventricular septal defect and case, so, the color goes beyond and diagnoses the lung artery to lock several respects under the main attention of companion's ventricular septal defect:
1.The diagnosis of locking the lung artery and ventricular septal defect: Lung artery lock patient of companion ventricular septal defect the intersection of ventricular septal defect and the intersection of position and majority in the intersection of membrane and week position or the intersection of funnel and position, it is bad to the location to present. The aorta rises to increase widely and riding above the interventricular septum, the diagnosis to ventricular septal defect is not difficult. But range and intensity that the lung artery is locked are widely different, can involve the lung artery one is played, lung artery one, lung artery is always dry, even lung artery branch. The aorta root stub axle and lower arrow tangent plane of sword,etc. can reveal the right ventricle flows out a connection with the lung artery by the brestbone, right ventricle and the intersection of lung and connection of artery break down, come from right ventricle flow into the intersection of lung and artery to the blood flow ago in the intersection of lung and artery, there is continuous blood flow that is confirmed in the lung artery branch as the lung artery and locked. And lung the intersection of artery and severe narrow the intersection of Fallow and the intersection of block of four and lung, patient of disease, have, come from right room flow out at a high speed blood flow of dish in the artery, repeated numerous exploration, regulate appropriate Doppler, gain to confirm lung shape and the intersection of judgement and right room of artery flow out dish, can obviously improve the rate of accuracy diagnosed with the intersection of lung and the intersection of artery and continuity of blood flow. The simple lung artery one can see the valve to increase thick while locking, has not opened and closed the activity, it is not difficult to diagnose. Many cases infants got the lung artery one to lock, lowered the aorta - side of lung and propped up the artery to circulate and take shape recently. But most the intersection of lung and more extensive ranges that artery lock, move with right room flowing out dishes of walling, merging the right room flowed out one to stop up before the funnel portion, lung the intersection of artery and petal and the intersection of lung and artery do, develop bad seriously always, difficult to reveal in above-mentioned tangent plane, it makes the heart veer the location that the right room is expanded, and wild influence of the lung increases the difficulty that pursues to be checked aroused in interest of the supersound. And nuclear magnetic resonance the intersection of blood vessel and formation of image and spiral CT lock lung artery situation, companion of ventricular septal defect, reveal to the intersection of lung and artery that there is unique value, it can be a strong monitoring basis of congenital heart disease treatment, check the deficiency that can also remedy the supersound and diagnose in radiography of cardiovascular vessel.
