What are the effects of doing angiography?
With the continuous development of medical technology, imaging examinations play an increasingly important role in clinical diagnosis. Whether it is cardiac angiography, angiography or other angiography examinations, they can help doctors observe the structures in the body more clearly and make more accurate diagnoses. However, many patients have concerns about the impact of angiography. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the impact of imaging examinations in detail, and provide structured data for reference.
1. Common types of imaging examinations
Angiographic examinations can be divided into many types depending on the location and purpose of the examination. The following are common imaging tests and their uses:
| Check type | Main purpose |
|---|---|
| Cardiac angiography (coronary angiography) | Diagnosis of coronary heart disease, myocardial ischemia and other heart diseases |
| Angiography | Assess for vascular lesions such as stenosis, thrombus, or aneurysm |
| CT contrast-enhanced imaging | Improve the clarity of tumors, inflammation or other lesions |
| MRI contrast | For detailed imaging of the nervous system, soft tissue and more |
2. Potential Impact of Radiography Examination
Although angiography is of great value in diagnosis, it may also have some potential consequences. The following are the areas that patients are most concerned about:
| Impact type | Specific performance | probability of occurrence |
|---|---|---|
| allergic reaction | Itchy skin, rash, difficulty breathing, etc. | About 1%-3% |
| renal impairment | Elevated serum creatinine, more common in patients with renal insufficiency | About 5%-10% (high-risk group) |
| radiation exposure | Ionizing radiation in X-ray or CT imaging | Depends on test type and dose |
| puncture site complications | Hematoma, infection, or blood vessel damage | About 1%-2% |
3. How to reduce the impact of imaging examinations
To minimize the potential risks of angiography, patients and doctors can take the following steps:
1.Preoperative evaluation:Doctors should learn more about the patient's medical history, especially allergies and kidney function, and conduct blood tests if necessary.
2.Choose a low-risk contrast agent:For patients at high risk for allergies, nonionic contrast media or low-osmolarity contrast media may be used.
3.Fully Hydrated:Drinking plenty of water before and after the examination will help speed up the excretion of contrast agent and reduce the burden on the kidneys.
4.Postoperative observation:You should stay under observation for a period of time after the examination to detect and deal with possible complications in time.
4. Precautions for angiography examination
Before undergoing angiography, patients should pay attention to the following:
| time point | Things to note |
|---|---|
| Before inspection | Fast for 4-6 hours (fasting is required for some examinations), and inform the doctor of your medication and allergy history |
| Under inspection | Cooperate with the doctor's instructions, maintain a stable posture, and report any discomfort immediately |
| After inspection | Drink plenty of fluids, monitor the puncture site, and avoid strenuous exercise for 24 hours |
5. Future development trends of imaging examinations
With the advancement of medical technology, imaging examinations are developing in a safer and more accurate direction. For example, research into new contrast agents, such as nanoscale contrast agents, is expected to further reduce the risk of allergies and kidney damage. In addition, the application of artificial intelligence technology has also improved the efficiency and accuracy of image analysis, providing patients with more personalized diagnostic solutions.
In short, although angiography examinations have certain effects, the risks can be controlled with the professional guidance and adequate preparation of doctors. For patients who need to undergo angiography, understanding the relevant knowledge and fully communicating with their doctors are the keys to reducing worries.
