Is coronary angiography dangerous

summary

Everyone wants to have a healthy body. Some patients have coronary angiography. Any operation is a certain risk, a little careless will endanger life, and coronary angiography will cause a lot of complications. Now let's talk about the risk of coronary angiography.

Is coronary angiography dangerous

First, pseudoaneurysm is a hematoma formed by blood flowing out of the femoral artery puncture and being wrapped by adjacent tissues, through which blood can flow back and forth between the femoral artery and the aneurysm. Its common symptoms are local pain, sometimes more severe, when the tumor is too large can also produce peripheral nerve vascular compression symptoms. Palpation can find subcutaneous hematoma, pulsation, auscultation can be heard and obvious systolic murmur, larger diameter can be cured by compression, thrombin injection and surgical repair.

Second, femoral arteriovenous fistula refers to the formation of abnormal channels between femoral artery and vein caused by femoral artery puncture. Most femoral arteriovenous fistulas have no obvious symptoms and do not lead to serious complications. Many small arteriovenous fistulas can heal by themselves. In a few cases, due to the large blood flow of arteriovenous fistula, it can lead to venous dilatation and varicose, or the patient has serious distal femoral artery stenosis, which can lead to "steal blood" phenomenon and aggravate lower limb ischemia.

Third: retroperitoneal hemorrhage, because the retroperitoneal cavity has more space, can store a lot of blood; retroperitoneal hematoma occult, when there are obvious symptoms, such as hypotension, often prompt severe bleeding, if the diagnosis and treatment is not timely, it will lead to death, is the most dangerous complication related to the femoral artery pathway. The main symptoms and signs are anemia, hypotension, abdominal tension, lower abdominal pain and sweating. The diagnosis depends on CT examination.

matters needing attention

The above three cases are the common complications of coronary angiography. We can see that a little careless treatment will cause damage and bleeding, and it will also cause hematoma in the patient's body, with a sense of pressure all the time. Severe complications can directly lead to death, so coronary angiography is a very dangerous operation.
