Endovascular Procedures

Our vascular surgeons offer expertise in a full range of minimally invasive endovascular procedures. Endovascular (“inside the blood vessels”) procedures are performed through a small puncture wound or incision, as opposed to traditional open procedures, which require a larger incision and a longer recuperation time.

Endovascular surgery procedures that we offer include:

  • Percutaneous Transluminal Angioplasty (PTA) and Stenting
  • Endovascular Aneurysm Repair (TEVAR)
  • Rotational and Orbital Atherectomy
  • Carotid Angioplasty and Stents
  • Pharmacomechanical Thrombolysis for DVT (Trellis Proc)
  • IVC Filter Placement

Percutaneous Transluminal Angioplasty (PTA) and Stenting

A long, thin, flexible tube called a catheter is inserted into an artery of your arm or leg after it is punctured with a small needle puncture in an artery of your arm or groin. The catheter is guided through the arteries to the blocked area anywhere in the body. Once in place, a special catheter, which has a balloon at its end, is inflated. The balloon pushes the plaque in the artery against the artery walls, widening the vessel.

At this point, if the result is not optimal, your vascular surgeon may place a tiny mesh-metal tube, called a stent, into the narrowed artery.

Endovascular Aneurysm Repair (EVAR)

This procedure is a minimally invasive way to correct abdominal aortic aneurysms that cuts surgery time in half and is done under local or spinal anesthesia. Small incisions are made in both groins and catheters containing self expanding covered stents are placed under X-ray. This procedure reduces the hospital stay from 7–10 days to 24–72 hours and total recovery time from 6 weeks to less than one week.

Thrombolytic (Lytic) Therapy

When arteries or bypass grafts in the extremities or abdomen become acutely blocked they can often be reopened with the use drugs called lytic agents. These agents are administered through a small catheter in the artery and dissolve the clot, avoiding the need for surgery. Lytic therapy can also be used to dissolve clots in the large veins of the arms and legs in order to preserve vein valve function and prevent pulmonary embolism.
