Ana Gamboa Webelman has suffered four venous thromboembolic events, or deep vein blood clots, during her lifetime.

Patient selection criteria and interventional treatment parameters for renal artery stenosis

The medical community has made great strides treating coronary and carotid artery diseases and reducing mortality associated with myocardial infarctions and strokes.

Recurrent DVT treatable even in complex cases

March is DVT Awareness Month. Up to 600,000 people are hospitalized in the United States each year for Deep Vein Thrombosis (DVT). If left untreated, DVT cases can lead to Pulmonary Emboli, which are blood clots that escape into the circulation and become lodged in the lungs. They result in nearly 60,000 deaths each year.
