This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femor...
To determine the effect of three different percutaneous revascularization strategies (Balloon Cryoplasty vs. Stent Placement vs. Atherectomy) in the treatment of lifestyle limiting lower e...
Restenosis is still an issue after endovascular revascularization for femoropopliteal occlusive disease. One approach to reduce the rates of restenosis and reintervention is local applicat...
In patients with ST elevation myocardial infarction (STEMI) the treatment goal is revascularization of the occluded artery with the use of primary percutaneous coronary intervention (PCI)....
The purpose of the study is to learn which treatment option is better for patients who have multi-vessel coronary artery disease (blockages in more than one vessel supplying blood to the h...
To report on procedural, safety, and effectiveness outcomes of real-world practice with the Jetstream rotational atherectomy system for treatment of femoropopliteal artery lesions.
Chronic total occlusions (CTO) are common in patients with symptomatic peripheral arterial disease. Endovascular CTO intervention remains a challenging endeavor for interventionalists, but is being in...
More than half of the patients undergoing percutaneous coronary intervention (PCI) have multivessel disease. Whether complete revascularization impacts long-term mortality or whether selected patients...
: Relapsing angina is infrequent, although not negligible in patients with previous history of percutaneous revascularization. Symptoms may be related to in-stent restenosis, to the development of neo...
The objective of this study was to evaluate the relationship between inflammatory markers interleukin (IL)-1β, IL-6, IL-8, IL-10, tumor necrosis factor α (TNF-α), transforming growth factor β (TGF...
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularized tissue to the surface of the brain.
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
