How to judge whether blood vessels are blocked?

Of course, we dare not boast that we can accurately judge 100%, but almost all cardiovascular blockages can be detected except those with atypical symptoms, insensitive examination and unwillingness to further examine.

Let me briefly share with you how I judge cardiovascular blockage:

1. The patient has persistent angina symptoms, such as chest pain, precordial pain, back pain, pharyngeal tightness and abdominal pain. These symptoms persist or are accompanied by sweating and frequent death.

2. ECG showed that the ST segment was raised like a hunchback. At this time, vascular occlusion can be basically diagnosed, and it is necessary to decide whether to thrombolysis or stent reperfusion.

3, if thrombolytic therapy, according to the electrocardiogram changes, myocardial enzyme changes, symptoms to judge whether the blood vessels are unobstructed; If angiography is more intuitive.

4. If the ECG is atypical, just ischemic or atypical symptoms, we also need the support of myocardial enzymes. Myocardial enzymes are multiplied, which helps us to judge whether blood vessels are blocked.

5. There are still some chronic occlusive blood vessels in clinic, which can only be found by angiography.

Therefore, the judgment of whether the cardiovascular system is blocked is based on symptoms, electrocardiogram, myocardial enzymes, angiography and so on.

Second, we need to talk about cerebral vascular occlusion, which is cerebral infarction.

As for "which methods to dredge blood vessels are more reliable?" If there is acute vascular occlusion, there are two ways to "dredge the blood vessels". One is thrombolytic therapy, including intravenous thrombolysis and arterial thrombolysis. They have the best time window. If it is cerebrovascular, it should be within 6 hours, preferably within 4.5 hours. If it is cardiovascular, it can be within 6 hours, preferably within 3 hours. Another reliable method of "dredging blood vessels" in acute vascular occlusion is interventional therapy to remove thrombus. Under X-ray, a catheter can directly enter the thrombus site and a guide wire can be used to "take out" (pull) the thrombus.

If it is chronic occlusion, if it is not 65,438+0,000% occlusion, there will be an opportunity for interventional therapy. Stent placement will "enlarge" the vascular lumen and is also a reliable method to dredge blood vessels. Cardiovascular and cerebrovascular diseases, lower limb blood vessels, renal blood vessels, etc. There are interventional therapy techniques.
