General Information

The doctors at South Florida Vascular Associates specialize in minimally invasive treatments performed using imaging guidance. Interventional radiology is a rapidly growing area of medicine. The minimally invasive techniques used by interventional radiologists are an advance in medicine that often replaces open surgical procedures. They are generally easier for the patient because they involve no large incisions, less risk, less pain and shorter recovery times.

Physician Profile

Dr. Julien received his medical degree from the Washington University School of Medicine in Saint Louis, MO. He served his residency in Diagnostic Radiology at the University of Minnesota Hospital in Minneapolis. Dr. Julien is fellowship trained from Miami Cardiac and Vascular Institute in Interventional Radiology. Dr. Julien is certified by the American Board of Radiology with a Certificate of Added Qualification in Interventional Radiology, he is also a member of the Radiological Society of North America and the Society of Interventional Radiology, in which he is a member of the Practice Affairs Committee. Dr. Julien also serves as a member of the Council on Cardiovascular Radiology for the American Heart Association.  Dr. Julien is the President of South Florida Vascular Associates. He is also on staff at Northwest Medical Center in Margate.

Dr. Julien has had the privilege of being Director of Interventional Radiology at Florida United Radiology, as well as Chief of Interventional Radiology at a 3 hospital system here in South Florida. Dr. Julien has been principal investigator for several device trials for medical break-through procedures including carotid artery stenting in which he was the first South Florida physician to implant the newly approved filter device upon its post-market approval. Because his skills are so specialized, Dr. Julien has frequently been asked to speak at national endovascular meetings and has also had the privilege of training many physicians on cutting-edge minimally invasive procedures.

Dr. Julien is on the advisory boards of Boston Scientific, Diomed and Medcomp Dr. William Julien’s endovascular practice is unique in that, unlike most interventional radiologists, Dr. Julien sees his own patients and treats many of them right in his office in a sophisticated endovascular surgery suite – one of the first of its kind in the country. Dr. Julien places a strong emphasis on the importance of patient education offering his patients clear explanations on the details of a diagnosis,  treatment plans, alternative treatment, and precisely what each patient should expect to experience. His practice has been highlighted as a model for the next generation of Interventional Radiology Practices.

These are just a few forms of treatment South Florida Vascular Associates performs Endovenous Laser Treatment, or EVLT, is an alternative to surgical stripping of certain underlying veins that are the source of surface varicose veins. Endovenous Laser Treatment is done in-office under local anesthesia. It works by heating the inside of the vein, which causes it to seal shut and disappear. It is simple, effective, and is the first choice of patients and physicians. The treatment takes less than an hour to eliminate varicose veins. Carotid artery stenting is an endovascular technique used to re-open blocked carotid arteries and prevent stroke. Because carotid stenting is minimally invasive, it provides an excellent treatment option to patients who are high-risk candidates for endarterectomy surgery. The procedure requires only a local anesthetic and a tiny puncture into an artery in the groin area, rather than opening the artery in the neck.

The blockage is treated with balloon angioplasty and the placement of a stent - a small, self-expanding metal tube or 'scaffold' that keeps the vessel open, thereby preventing a stroke from occurring. A tiny umbrella-like filter is used to catch and remove loose pieces of plaque that develop during the stenting procedure before they travel to the brain and create a stroke.  Sclerotherapy is considered the gold standard treatment for removing spider and some varicose leg veins. It is a very cost-effective procedure that seldom leaves a scar or produces adverse effects.  A concentrated saline or specially developed chemical solution is injected with a very small needle into the spider or varicose vein. The solution causes the vein to close up or collapse and become scar tissue that is eventually absorbed by the body. The work of carrying the blood is shifted to other healthy blood vessels nearby. 

Sclerotherapy generally requires multiple treatment sessions. One to three injections are usually required to effectively treat any vein. The same area should not be retreated for four to six weeks to allow for complete healing, although other areas may undergo treatment during this time. Walking and moderate exercise helps to speed recovery. Although sclerotherapy works for existing spider and varicose veins, it does not prevent new ones from developing, but may decrease this risk.
Thrombolysis is the treatment to break up abnormal blood clots that are restricting blood flow. Thrombolytic therapy dissolves these blood clots using various medications administered directly into the clot through a catheter. Mechanical thrombolysis is the disruption of a blood clot using one of several mechanical devices. An interventional radiologist can use either or both of these methods to dissolve and remove blood clots. The procedure is performed by an interventional radiologist, a physician specially trained to perform thrombolysis and similar procedures. Radiologic thrombolysis can greatly improve blood flow and reduce or eliminate the related symptoms and effects without the need for more invasive surgery.
