关键区别 - PTCA对PCI
Percutaneous Transluminal Coronary Angioplasty (PTCA) and Percutaneous Coronary Intervention (PCI) both essentially mean the process of dilating a coronary arterystenosisusing an inflatable balloon and a metallic stent introduced into the arterial circulation via the femoral, radial or the brachial artery. Nowadays it is the most commonly used intervention in the treatment of缺血性heart diseases. It should be stressed that there isnodifferencebetween PTCA and PCI. They are in fact synonyms. However, here, we will discuss PTCA or PCI procedure and complications in detail.

What is PTCA?
经皮式冠状动脉血管成形术或PTCA是一种用于治疗缺血性心脏病的方法,这是由于冠状动脉循环中的阻塞所致。它可以定义为使用充气球囊和金属的冠状动脉狭窄的过程stent通过股骨,径向或肱动脉引入动脉循环。在存在软病变的情况下,预后有更好的预后,不涉及任何动脉分叉。
PTCA is not recommended when the site of obstruction is within a calcified, long and tortuous artery which is bifurcating at an adjacent point.
Complications of PTCA
- 内部hemorrhages
- 血肿
- Dissection andpseudoaneurysmsfrom the arterial puncture site. Risk of this can be minimized by using the radial artery to gain access to the arterial circulation.
- Serious but rare complications are acutemyocardial infarction,中风, and death.
The risk of血栓形成的先前给药以下一种或几个药物可以减少并发症。
- 肝素
- Bivalirudin
- Antiplateletdrugs
- Aspirin
- GP IIb/IIIa antagonists are used in the patients having very high risk acute coronary syndrome ordiabetes.

The recent introduction of the stents coated with a drug capable of preventing the restenosis of the damaged vessel has minimized the necessity of repeated revascularization. These stents are known as the drug-eluting stents. There are different varieties of stents according to the drug they are coated with. Concerns have been raised over the increased possibility of late stent thrombosis. The lack of endothelialization of the stent is believed to be the basis for this increased risk. Therefore, all the patients who have undergone PTCA are advised not to discontinue the dual therapy with aspirin and clopidogrel within 6-12 months of implantation.
What is PCI?
Percutaneous Coronary Intervention is another name given to PTCA. Therefore there is no difference between these two terms.
PTCA和PCI有什么区别?
- PTCA和PCI之间没有差异,因为经皮式冠状动脉血管成形术或PTCA也被称为经皮冠状动脉介入或PCI的名称。
概括– PTCA对PCI
PTCA or Percutaneous Transluminal Coronary Angioplasty is the process of dilating a coronary artery stenosis using an inflatable balloon and a metallic stent introduced into the arterial circulation via the femoral, radial or the brachial artery. Percutaneous Coronary Intervention is another name given to this procedure. Therefore, there is no difference between PTCA and PCI.
