Some patients after stenting will have swelling of both lower extremities, but there are more diseases that can cause swelling of both lower extremities, so first we have to make a differential diagnosis. Because the stent itself does not cause swelling of both lower extremities. First of all, we need to clarify whether the patient has contrast renal damage, that is, contrast nephropathy, because this problem can also indirectly cause the patient to have swelling of both lower extremities. There are also some patients who have coronary heart disease with stents often accompanied by some other cardiovascular diseases, such as hypertension, to clarify whether the patient is taking some antihypertensive drugs, resulting in swelling of the lower extremities, especially like some calcium antagonists, one of its side effects is that it can lead to swelling of the lower extremities. There are also people who have hypothyroidism, and people with hypothyroidism may also have swelling of the lower extremities or even the whole body. Some people with acute myocardial infarction and coronary artery stenting may have poor recovery and secondary heart failure, which may also indirectly lead to swelling of both lower extremities. This situation should be combined with treatment to correct heart failure. It should also be excluded that some women in menopause belong to hormonal imbalance, which may also lead to edema, but you should rest assured that the installation of stents will not cause you to have edema.
