Interventional Radiologists use their expertise in viewing x-rays, ultrasounds and other medical images to guide small instruments through the skin to treat various conditions and obtain specimens for diagnostic testing. These procedures are much less invasive than surgery and often as an alternative. Most procedures require minimal sedation which is provided by the Interventional Radiology nurses that work closely with the Radiologist to provide individualized patient care.
We have a team of experienced nurses dedicated to care for patients who are scheduled to have an interventional procedure performed. The interventional radiology nurses provide care before, during and after the procedure. The nurses will closely monitor the patient during the procedure and provide sedation and other medication to ensure patient comfort. Family members are updated on patient status during the procedure and informed upon completion of the procedure by the Radiologist. The nurse keeps the Radiologist updated on the patient's progress during recovery and the Radiologist is readily available to answer any questions or concerns you may have.

Interventional Neuroradiology Tumor Debulking-Coblation
Tumor debulking, or coblation, uses radiofrequency energy to excite the electrolytes in a conductive medium, such as saline solution, creating a precisely focused plasma.
The plasma's energized particles have sufficient energy to break molecular bond within tissue, causing tissue to dissolve at relatively low temperatures (typically 40°C to 70°C). The result is volumetric removal of target tissue with minimal damage surrounding tissue.
Because radiofrequency current does not pass directly through tissue during the coblation process, tissue heating is minimal. Most of the heat is consumed in the plasma layer, or in other words, by the ionization process. These ions then bombard tissue in their path, causing molecular bonds to simply break apart and tissue to dissolve.
Coblation may be used in conjuction with vertebroplasty or kyphoplasty to treat vertebral compression fractures caused by tumors.
How the Procedure Works Tumor in vertebral body.
Insert access cannula.
Deploy tissue debulking Spine Wand.
Remove tissue to debulk tumor and create cavity.

The same cutting edge technology used for these interventional radiologic procedures can also be used in the skilled hands of a specialized electrophysiologist to correct heart rhythm.
