Endovascular intervention for treatment of arterial occlusion below the knee

The article was consulted with Dr. Tran Hong Nhat - Interventional Cardiologist - Cardiovascular Center - Vinmec Central Park International General Hospital.

The occlusion of the artery below the knee not only causes pain and difficulty in moving the patient, but in the severe stage, it can cause ulceration and necrosis of the extremities. Endovascular intervention is an effective method in the treatment of arterial occlusion below the knee.

Sub-knee occlusion occurs due to atherosclerosis or endarteritis, which reduces blood flow to the extremities below the site of injury. The disease is susceptible to smokers, diabetes, hypertension, dyslipidemia, sedentary lifestyle, obesity... If not treated promptly, it will cause severe tissue anemia, leading to limb necrosis.

With occlusive disease in the sub-knee area, the optimal, less painful treatment for the patient is to re-circulate the blocked artery by means of percutaneous stent dilatation with a catheter. Instruments are leads, balloon catheters, and stents, which are delivered to the site of injury through a needle puncture in the femoral artery. The balloon catheter is inserted into the narrow/obstructed site of the vessel to widen the lumen. Next, a metal stent attached to another catheter is inserted to widen the lumen and keep the lumen from narrowing. When the lumen is opened, blood flow is restored, the symptoms of pain, leg fatigue when walking and pain at rest due to ischemia will be reduced quickly.
The basic steps in the interventional procedure for revascularization in the lower knee area include:
Pre-interventional injury assessment: Doppler ultrasound, multi-slice computed tomography (MSCT) to assess the lesion. into the artery: performed under ultrasound guidance Angiography to assess the lesion Approach and pass through the site of stenosis Identify the downstream circulation (runoff): Small balloon angioplasty Angioplasty Angioplasty pulse check Doppler ultrasound assessment 48-72 hours after intervention Anti-re-stenosis: The patient was given anticoagulant and antiplatelet drugs to prevent restenosis after intervention

Periodic re-examination Time of follow-up: 1 - 3 - 6 - 12 months after intervention Criteria to be assessed: clinical symptoms, ABI index, risk factors (blood fat, blood sugar, .. .), vascular doppler ultrasound. Take CT scan / MRI of blood vessels if there are signs of restenosis. The occlusion of the artery below the knee not only causes pain and difficulty in moving the patient, but in the severe stage, it can cause ulceration and necrosis of the extremities. Therefore, early diagnosis and treatment is essential to minimize possible dangerous complications.
Vinmec International General Hospital is a general hospital with the function of examining, diagnosing and treating many diseases, including cardiology.
