How to treat the echocardiographic results after type ⅲ aortic dissection surgery?

Aortic dissection means that the blood in the aortic cavity enters the aortic media from the tear of the aortic intima, which separates the media and expands along the long axis of the aorta, forming a state of separation between the true and false aortic walls. If the patient has aortic dissection, postoperative reexamination is usually needed. After surgery, it should be reviewed every three months and once a year. Generally speaking, he can do color Doppler ultrasound and chest X-ray. Some qualified people can also do aortography to enhance CT.

If the blood vessels are unhealthy due to long-term hypertension or other reasons, a gap will be formed between the intima and media of the aorta, and blood will enter between the intima and media, forming a true cavity and a false cavity. The reexamination items after aortic dissection include electrocardiogram, color Doppler echocardiography, coronary artery CTA, coronary angiography, aorta CTA and abdominal aorta CTA. Through these examinations, the survival of various blood vessels and coronary angiography can be determined. According to the examination results, choose appropriate drugs for cardiotonic diuretic treatment, and prolong the life of patients as much as possible.

Color Doppler electrocardiogram can first judge whether the cardiac function of aortic insufficiency, pericardial effusion and dissection is good, which has important clinical significance for further treatment in the future. The most routine and important review content is aortic CTA, which can not only evaluate whether there is dissection at the operation site, whether there is thrombus and residual aortic dissection near and far, but also judge whether the anastomosis of aortic dissection near and far after artificial blood vessel replacement is narrow and whether there is thrombus in artificial blood vessel.

For aortic dissection with stent, it can be determined whether there is a new dissection at the proximal and distal ends of the stent and whether the distal stent will cause further tearing of the aortic intima. In addition, CTA of aorta can also determine whether there is thrombosis, stenosis and new dissection in distal organs, such as renal artery, mesenteric artery and iliac artery. ?
