Reasons for the Causes

Angioplasty is a treatment to expand narrowed or blocked blood vessels, but it may not always be successful due to various reasons. The reasons for angioplasty failure involve a complex interplay of factors such as the condition of the blood vessel, the patient's constitution, and the surgeon's skill. It is difficult to make a definitive statement, but research has revealed some common causes.

General Causes

Blood Vessel Structure

Angioplasty can be difficult if the blood vessel structure is complex and the stenosis or blockage is severe. 2 suggests that the severity of PAD can affect the difficulty of angioplasty.

Hardening of Blood Vessel Walls

If the blood vessel walls are hardened, the expanded area may return to its original state even after dilation with a balloon. 7 suggests that hardening of the blood vessel walls may contribute to restenosis after balloon angioplasty for coarctation of the aorta.

Thrombus Formation

Thrombosis can occur after angioplasty. shows that thrombolysis is effective in treating acute upper extremity deep vein thrombosis. 16 mentions thrombosis as a cause of dysfunction in tunneled cuffed catheters.

Restenosis of Blood Vessels

The blood vessel may narrow again after angioplasty. 7 suggests that hardening of the blood vessel walls and intimal hyperplasia may contribute to restenosis. 21 suggests that drug-coated balloon (DCB) angioplasty can prevent restenosis in arteriovenous fistulas.

Patient Condition

If the patient's condition is poor, the risk of angioplasty is increased. 4 shows that age and recent coronary angioplasty influence survival rates in liver transplantation for non-alcoholic fatty liver disease (NAFLD) cirrhosis.

Measures to Address Causes

Blood Vessel Structure

If the blood vessel structure is complex, it is necessary to thoroughly check the condition of the blood vessel beforehand using imaging tests such as CT and MRI. 2 suggests different imaging test choices based on the severity of PAD.

Hardening of Blood Vessel Walls

Stents can be used instead of balloons if the blood vessel walls are hardened. 7 suggests that stents can prevent restenosis in coarctation of the aorta. 22 suggests that the type of stent can influence the efficacy of angioplasty for chronic mesenteric ischemia.

Thrombus Formation

Antithrombotic drugs need to be administered to prevent thrombosis. shows that thrombolysis is effective in resolving thrombi.

Restenosis of Blood Vessels

To prevent restenosis, drug-coated stents or antithrombotic drugs need to be administered after angioplasty. 7 suggests that stents can prevent restenosis. 21 suggests that drug-coated balloon (DCB) angioplasty can prevent restenosis in arteriovenous fistulas.

Patient Condition

If the patient's condition is unstable, angioplasty may need to be postponed. 4 shows that age and recent coronary angioplasty influence survival rates in liver transplantation for non-alcoholic fatty liver disease (NAFLD) cirrhosis.

Comparison Between Studies

Commonalities Among Studies

Many studies indicate that although angioplasty has high success rates, there are risks of restenosis and complications.

Differences Between Studies

The success rate and risk of complications vary depending on the type of angioplasty and the target disease. 13 shows that most brachiocephalic vein occlusions in hemodialysis patients can be treated with simple endovascular techniques on an outpatient basis, while other studies show that angioplasty can be more complex in certain cases.

Notes on Applying Research to Daily Life

Angioplasty is an effective treatment for expanding narrowed or blocked blood vessels, but it is not suitable for all patients. It is important to consult with your doctor and choose the appropriate treatment based on your individual condition before undergoing angioplasty.

Limitations of Current Research

Many studies have only conducted short-term follow-up. Therefore, sufficient data is not yet available on the long-term prognosis of angioplasty. 22 suggests that the type of stent may influence long-term outcomes in patients with chronic mesenteric ischemia.

Future Research Directions

Long-term follow-up studies are needed to elucidate the long-term prognosis of angioplasty. Research is also needed to further improve the safety and efficacy of angioplasty.

Conclusion

Angioplasty is an effective treatment for expanding narrowed or blocked blood vessels, but it is important to understand the risks of restenosis and complications. It is essential to consult with your doctor and choose the appropriate treatment based on your individual condition before undergoing angioplasty.
