What are the side effects of coronary angiography?

Coronary angiography is currently a safe and effective method for treating heart disease. In fact, current coronary angiography technology is very mature and there is no risk, so you don’t need to worry too much in this regard. However, any surgery will have foreseeable side effects and risks, which everyone must be aware of, including complications and side effects that are likely to occur after surgery, and the hospital will inform the patients.

Risks of surgery

Explain to the patient or relatives the possible complications and risks of surgery during or after the operation. Some uncommon risks may not be listed here. The specific surgical procedure varies according to the patient's condition:

1) Allergic reaction: Drugs used during surgery (contrast agents, anesthetics, etc.) may cause skin allergies, breathing difficulties, anaphylactic shock, hemolytic reactions, etc.;

2) Complications at the puncture site: unsuccessful puncture, local hematoma, pseudoaneurysm or arteriovenous fistula formation, and damage to adjacent organs.

3) Complications related to selective intubation: vasospasm, vascular endothelial damage, arterial dissection or vascular rupture; thrombosis, mural thrombus or plaque detachment, causing ischemia and necrosis of the corresponding blood supply tissues and organs. Cerebrovascular thromboembolism (mostly caused by internal carotid artery plaque or embolus detaching from the heart).

4) Toxic side effects caused by contrast agents: allergic reactions, gastrointestinal reactions, bone marrow suppression, damage to heart, liver and kidney function, skin and mucosal ulcers, etc.;

5) Infection (including local and systemic).

6) Anatomical abnormalities and other reasons may cause the operation to be unsuccessful or require multiple operations.

7) Intracranial hemorrhage (including massive arterial or venous hemorrhage) and local hematoma due to puncture.

8) worsening of the disease or death in the operating room before the operation;

9) Paralysis or death caused by aneurysm rupture or bleeding during or after surgery; intracranial hemorrhage caused by anticoagulant therapy, and cerebral infarction or death caused by compression of blood vessels after bleeding;

10) The catheter is broken or knotted.

11) Surgery may cause retroperitoneal hematoma, which may be life-threatening.

12) Radiation may cause damage.

13) If no lesions are found during angiography, another examination may be required at a later date.
