The appearance of small bags after cardiography examination is considered to be related to allergy to contrast medium, local blood seepage and connective tissue hyperplasia.
1. Allergy to contrast medium: cardiac contrast examination usually selects radial artery and femoral artery as the entrance of catheter, and injects contrast medium to observe cardiovascular condition in a short period of time, if allergic to iodine-containing contrast medium, blister-like pockets may appear, which is often related to individual’s physique.
2. Local blood seepage: cardiography is an invasive test, when the pressure is not in place after the arterial puncture, it can lead to blood seepage to the surrounding soft tissues, at this time, small packets can appear near the puncture point.
3. Connective tissue hyperplasia: after cardiography, if there is local connective tissue hyperplasia at the puncture point when the wound is healing, small packets may also appear around the periphery.
The appearance of small bags after cardiography may also be related to other reasons, it is recommended to consult a doctor in time to clarify the specific causes, and under the guidance of the doctor to carry out standardized treatment.
