Treatment Mode

There are many causes of pulmonary artery stenosis, such as arteriosclerosis, fibrosis intimal hyperplasia, and even pulmonary embolism. Clinical treatment should be selected according to the scope, location and degree of pulmonary stenosis. If it is a transient lesion, it can be treated by endovascular minimally invasive methods, like other places to place stents, through the vein into the inferior vena cava, across the heart to the right atrium and pulmonary artery. After the guide wire has passed, the balloon can be opened to solve the problem of pulmonary stenosis. A support bracket can be placed if necessary.

If the scope is large or the stenosis is very serious, and the stent is difficult to solve the problem, you need to go to the cardiac surgery department to see whether you can do pulmonary endarterectomy, etc. If the scope is relatively large, you may only do lung transplantation.

Current treatment methods and development prospects

Introduction of interventional therapy -- balloon

Balloon dilation is recommended for patients with mild to moderate stenosis (stenosis rate <70%) or incomplete occlusion. Among the balloon expansion products, bare balloon has been certified and successfully applied in China.

Drug-coated Balloon

Introduction of interventional therapy -- balloon

The Drug-coated Balloon (DCB) for pulmonary artery stenosis is a relatively new treatment that combines the advantages of medication with traditional interventional treatments such as balloon dilation. By coating the surface of the balloon with medication, it helps dilate blood vessels while reducing the risk of restenosis. This treatment has been widely used in the treatment of coronary artery stenosis, but its application in pulmonary artery stenosis is still in the stage of research and early clinical trials.

The basic principle of drug balloon

Introduction of interventional therapy -- balloon

The basic principle of drug balloon

The drug balloon mainly uses the action of drug coating to reduce the local inflammatory reaction and the proliferation of vascular smooth muscle through the local release of drugs while the blood vessel dilates, andreduce the occurrence of restenosis

Advantages of a drug ballon

The basic principle of drug balloon

Reduce intravascular restenosis:Compared with simple balloon dilatation, the drug balloon can effectively reduce intimal hyperplasia and prevent restenosis through the action of drugs.
Reduced adverse reactions: The local release of the drug coating allows the drug to act directly on the blood vessel wall, reducing systemic side effects.

The drugs used in the drug balloon are mainly anti-proliferative drugs, such as Everolimus and Paclitaxel. These drugs reduce the risk of restenosis by inhibiting smooth muscle hyperplasia and reducing thickening of the blood vessel lining. The successful application of paclitaxel in coronary artery therapy has provided a theoretical basis for its application in pulmonary artery stenosis.
