Patients are given mild sedation through an IV inserted in the arm during the procedure. An interventional radiologist inserts a small, thin balloon tipped catheter into an artery and places it at the blocked vessel. The balloon is inflated under x-ray guidance to open the artery and improve blood flow. The balloon is then deflated. Vascular stenting occurs when balloon angioplasty is ineffective. After the artery is opened by the balloon, a small wire tube is inserted to maintain the opening. Once the angioplasty and or stent placement is complete, the catheter is removed. Patients are then moved to recovery; typically are able to walk within a few hours after the procedure and resume normal activity within one week. Often, patients will have follow up imaging of the artery which may include an ultrasound, CT (computed tomography) or MRI (magnetic resonance imaging) exam.
