not necessarily!
After all, coronary angiography is a "invasive" "surgery", so some patients will be more nervous after stenting and do not want to lie on the operating table again.
Dr. Ha understands this mood very well, and here is also explained to you:
First, it is not necessary to review the contrast after the bracket
For example, if the lesion is very simple, one or two stents are placed on one blood vessel, other blood vessels do not have serious plaques, there are no symptoms in the postoperative year, and the medicine is never interrupted, then the re-examination can be done without checking the angiography.
Second, what situations after stenting may require re-examination of contrast?
1. Angina attack, or discovery of myocardial ischemia:
No matter how long after the stent, as long as typical angina symptoms appear, or if the ecglyogram and other physical examination finds a clear myocardial ischemic change, then further re-examination and contrast must be examined.
Because after all, the stent is left behind, the contrast can know whether the stent is in trouble (thrombosis in the stent or the narrowing in the stent), or if there is a problem with other blood vessels, and then take different measures.
2. Serious lesions or stents
If the location of the stent implant is critical (left trunk lesion or bifurcation lesion), it is best to do a re-examination after one year. Because this position is important, it can be fatal in the event of an accident.
If there are more stents implanted, a repeat contrast may also be required.
3. When stenting, a certain blood vessel can be placed or not
If the stent is implanted, in addition to the blood vessels at the stent site, other blood vessels also have lesions, and the lesions belong to critical lesions or close to the nearby lesions (simply put, the stent can be placed, or not stents), then generally about a year, it is recommended to review an angiography to see if the critical lesion has progressed or improved, and at the same time to see whether the original stent site is unobstructed.
4. The effect of the stent is not in the ideal state
If the stent is placed, the blood flow does not reach the ideal state. Theoretically, normal blood flow is grade 3 (grade 0 indicates vascular occlusion and no blood flow), but if the blood flow after stenting does not reach the ideal state of grade 3 for various reasons, then angiography can also be considered during review.
Third, not reviewing the angiography does not mean not reviewing!
Here's also a reminder that even if you don't need to review the angiography, don't forget to review it regularly after stenting:
Review time: Generally in 1, 3, 6, 9, 12 months after surgery, the specific review time of different hospitals may be different, it is recommended to follow the doctor's advice;
Review items: mainly including hematuria stool routine, blood glucose, blood lipids, liver and kidney function, blood pressure, electrocardiogram, echocardiogram, etc. Depending on the patient's symptoms, coronary angiography or CT is reviewed at 6 to 12 months if necessary. (Wen | Li Ying)
