Real-Time MRI-Guided Percutaneous Intervention for Aorto-illac and Femoropopliteal, Artery Stenosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine the use of magnetic resonance imaging (MRI) instead of x-rays to guide angioplasty in patients who require these treatments to treat blockages in leg arteries. Angioplasty is a procedure in which a balloon is inflated in a blocked artery to improve blood flow. MRI uses a magnetic field and radio waves rather than x-rays to show pictures of body tissues and organs. MRI shows all soft tissue, including the arteries, blood, and other organs, while the usual x-ray technique shows only the lumen of the artery when it is filled with dye, but not the vessel walls. Patients 18 years of age and older who require angioplasty with or without stenting to restore blood flow to the leg may be eligible for this study. Participants undergo the usual angioplasty procedure. The skin in the patient's groin area is numbed and a catheter is placed into the groin artery. The patient is given a blood-thinning medicine, and then other catheters are inserted to measure blood pressure and to inject a contrast dye to take pictures. Balloon catheters are inflated to open the blockage and, if needed, stents are put in place to maintain the opening. When the blood thinner wears off, the catheters are removed. Most of the procedure is conducted using MRI instead of X-rays to visualize the arteries and blockages. The patient is moved back and forth between the x-ray and MRI machines in a specially designed laboratory. If necessary, stenting, placement of a wire mesh to hold open the artery, is done using conventional x-ray techniques. The entire procedure, including MRI, takes up to 4 hours.
