Chapter 1602 【1602】Too Hard to Find
Dr. Xu slapped the student's head again: You admit defeat?
In fact, it is not necessarily more difficult to check. The free thrombus may be small or attached to the wall, making it difficult to distinguish. If you go to the source, you may be able to find a relatively large one. The damaged heart will definitely show certain changes in anatomical structure.
With this idea as a guide, doctors in the CT room must scan carefully when scanning key areas for patients.
CT scan speed is not slow, but it takes time for doctors to read the film. Not long after, Xiao Shu was pushed out of the examination room. Xie Wanying came out to say hello to her cousin and sister-in-law, and told them to go to the inpatient department first, and stay in the office to read the film with Teacher Xu.
Due to the fine scans, hundreds of images are displayed on the computer, and it is not easy for doctors to read them one by one.
Xie Wanying and Dr. Zhao sat next to Teacher Xu and read together. To be honest, if you are not used to this job, at first glance at these hundreds of images that seem to be very similar, you really suspect that your eyes are going to be blind.
"This is the ridge, not a thrombus or a tumor." Dr. Xu pointed to a small gray area that seemed to be abnormally raised in the white area on the film.
The ridge border is the fusion line between the primordial atrial appendage and the sinus vena cava, located between the right atrial appendage and the sinus vena cava, and continues from the superior vena cava to the inferior vena cava. In the report of the doctor in the CT room of the Provincial People's Hospital, this was used as a sideline, because Dr. Xu saw at a glance that the report was partially fabricated.
Enhanced CT was done, and the thrombus in the right atrium seemed difficult to find. Then look for the ventricle that was highlighted in the discussion just now.
Thrombus was suspected in the right atrium, and the right ventricle was the focus of attention. Anatomically, the right ventricle can be divided into three parts, one is the inflow tract, the tricuspid valve inlet and its accessory structures. The second part is the outflow tract, a tubular structure such as the conus arteriosus that supports the pulmonary artery lobe. The third is the muscle trabecula between the above two.
When the heart is impacted by an external force, the first manifestation may be damage to the ventricular wall.
The wall of the right ventricle itself is very thin, only 3mm. The doctor needs to be more patient.
If there is no abnormality in the general outline of the heart structure, it depends on whether there is a problem with the activity function, and it is best to do an ultrasound examination. An echocardiogram can check valve activity and blood flow in the heart. From CT, only the static structure of the tricuspid valve and pulmonary valve can be identified.
Three pairs of eyes sifted through hundreds of images like a needle in a haystack.
Veteran doctors read a lot of films, and the angle of the brain when looking at the images changes quickly with the films. Young doctors may not be able to keep up with this rhythm.
Dr. Zhao rubbed his eyes from time to time. As a student of imaging, not only his eyes were blurred but his mind was confused. For this reason, he glanced at classmate Xie beside him.
Xie Wanying followed the teacher closely with her eyes fixed on her eyes, her expression was very calm and meticulous.
Teacher Xu is fast. Like the top three in the country, the CT room has a huge workload every day. When encountering difficult cases, the doctor may spend more time and energy on research, but if it is really impossible to find out, giving more time to study will have no effect. It is impossible to do research for a year and a half. It's not that the doctor can't wait, it's the patient's condition that can't wait. However, today's patients are more difficult to find. Dr. Xu can't take care of giving lectures to the students, and his brows are slightly anxious while staring at the images.
