At the same time, it is determined whether the aortic root, including the aortic sinus and coronary artery, is affected, and whether there is pericardial effusion and pleural effusion. The reconstructed image can provide two-dimensional and three-dimensional images of the entire aorta. The false lumen is usually located on the right side of the ascending aorta and the left side of the descending aorta. It can be semilunar or ring-shaped and is usually significantly larger than the true lumen.
Therefore, Wei Ping advocates direct CT angiography. Once the results of CT angiography come out, it will be easier to determine whether to undergo surgery or drug treatment.
"This disease is extremely dangerous. We need to first confirm its type."
There are two common classification methods for aortic dissection. Daily and Miller further divided aortic dissection into two types:
Those with ascending aorta involvement are type A (including DeBakey types I and II), and those with lesions opening at the distal end of the left subclavian artery are type B (i.e., DeBakey type III). Type A accounts for about 2/3 of all cases, and type B accounts for about 1/3.
DeBakey classified aortic dissection into 3 types:
Type I dissection originates from the ascending aorta and extends to the descending aorta.
Type II is limited to the ascending aorta,
Type III dissection originates from the descending aorta and extends distally.
Treatment of aortic dissection: Emergency treatment mainly focuses on pain relief and blood pressure reduction.
Type A dissection: Surgery as soon as possible under the premise of emergency treatment.
Type B dissection: Generally, drug treatment is given for two weeks, and after the acute phase, intravascular aortic isolation treatment, also known as interventional treatment, is performed; some complex cases require open surgery.
Regardless of the type, the treatment effect is now better, and the surgical mortality and disability rates have dropped significantly compared with previous years.
"Is this disease easy to cure?" asked the middle-aged woman.
This is also a concern of most patients.
