AUDIENCE: Neurology, Surgery, Health Professional, Patient
ISSUE: FDA is alerting the public about an experimental procedure called Transvascular Autonomic Modulation (TVAM). This procedure may put patients at risk because is being promoted as treatment for a variety of conditions even though it has not been formally studied in clinical trials. The procedure uses balloon angioplasty devices outside the scope of the FDA-approved indications for use.
BACKGROUND:TVAM consists of threading a catheter into a patient’s venous system, such as the jugular vein, where a balloon attached to the catheter inflates to widen the vein walls. At least one physician, Dr. Michael Arata, claims the procedure treats the signs and symptoms of autonomic dysfunction in a number of neurological disorders. The FDA has not reviewed any data that supports the safety and effectiveness of balloon angioplasty devices for this intended use.
RECOMMENDATION:For physicians providing care and potential clinical investigators: Be aware that the FDA has not cleared or approved any balloon angioplasty devices for the treatment of autonomic dysfunction, and has not been presented with data to support the use of such devices in treating autonomic dysfunction. Discuss the benefits and risks of all available treatments for autonomic dysfunction with patients, including the adverse events generally associated with catheter-guided endovascular intervention and those related specifically to use of balloon angioplasty devices for TVAM. Inform patients that TVAM is experimental, and that the FDA has not been presented with any data in order to assure the safety and effectiveness of balloon angioplasty devices used in this procedure. If you become aware of patients who have undergone the procedure, monitor them for potential complications such as excessive pain, discomfort, bruising, excessive bleeding from the puncture site, and stroke or stroke-like complications.
