1. Let's start with the first stent.
The heart a **** 3 blood vessels, if it is 2 blocked (is 100% lumen occlusion), then there is only one blood vessel left to supply blood, if this blood vessel then stenosis or occlusion, then the patient will indeed die immediately. If it is not 100% occlusion, then it is possible that myocardial infarction may occur in the future with occlusion, and myocardial infarction has a high mortality rate. So stenting is the way to go. But the decision is still up to the patient's family, and if the family refuses, no one will force it.
2. Chest pain again.
It should be acute thrombosis. As for the cause of thrombosis, it may or may not be stent displacement as you said, but no matter what the cause is, acute thrombosis in the stent is a possible complication of stenting, which can't be predicted in advance. And the fact that the patient presented with chest pain after returning to the ward suggests that the first stent was successfully implanted.
3. The second procedure.
According to the symptoms you described, the patient's general state is poor, his condition is critical, and there is indeed an indication for emergency surgery. The first step is to make sure that you have a good understanding of the situation, and that you have a good idea of what you are doing.
4. Surgical path.
The second time in the leg to do, because it was an emergency surgery, by the leg femoral artery path operation is easy, emergency medicine is concerned about the race against time, so from the leg to do and no problem.
5. Bleeding.
(1) The second operation by the femoral artery, in the femoral artery puncture, the puncture needle penetrates the skin into the femoral artery, see the blood from the end of the needle squirt out before the guidewire will be sent, this time there will be a certain amount of blood down the right groin flow to the bed.
(2) In the case of acute thrombosis, the second procedure will be thrombus aspiration and a certain amount of blood will be withdrawn.
(3) During the procedure, when the guidewire, balloon, and stent enter and exit the catheterization portal, a certain amount of blood will flow onto the surgical sheet, and if the sheet is not watertight, it is normal for the blood to stain the patient's body and bedding.
(4) Regarding the answer to the hand-washing water, that doctor you called may be just a nurse or intern who pushes the bed, not a surgeon, and doesn't understand the real reason and makes up his own mind.
6.3 days off the needle.
It should be low molecular heparin, which is meant to prevent acute thrombosis in the stent. 3 days off is fine. As it can increase the risk of bleeding.
7. About the cost.
If you follow the standard of the tertiary hospital, the domestic stent is about 12,000, the imported stent is about 19,000, a balloon is about 4,000, and the other guidewire, catheter, surgical fee, and monitoring fee is about 15,000. If the first stent used 2 balloons, 2 stents then the cost should be 45000-60000, the second stent if counted by 2 balloons, 1 stent should be 30000-40000. in this case you this hospitalization cost should be 80000 or so, the specific report how much depends on the type of medical insurance of your father.
8. About the cost of the second surgery
Your reasons are not good enough, because that was a complication, not caused by the doctor or the hospital, so this money is not possible if you want the hospital to take it. As you said, they did say humanitarianism.
9. About the doctor's attitude
The doctor felt that he was aggrieved, he felt that he was wearing 30 pounds of impenetrable lead coat for three hours, risking the death of his son (X-rays have a teratogenic effect) to save a person, not to thank it is just, but also rely on me, and also want to me to pay compensation for the money, who is also on the stomach of a fire.
10. On access to justice
You also think that you are aggrieved, you feel that you have spent so much money, people are almost dead, attitude is still so bad, put aside who can not stand. The law is the right of each and every one of us, and it's perfectly feasible. But I think the possibility of you winning the case is not great.
