IVC Filter Removal Takes Expertise

When Susan Karnstedt noticed abdominal pain, she had no idea it was caused by a lifesaving filter placed in her inferior vena cava years earlier. Karnstedt was referred to William Kuo, MD, an interventional radiologist who uses an endovascular laser to remove these filters.

Dr. Kuo's team is believed to be the first in the world to apply endovascular laser technology to successfully retrieve permanently embedded IVC filters, and Stanford is currently the only hospital in the country where these procedures are routinely performed.

Interventional Radiology Services

Our division is renowned for its long history of outstanding patient care, education and research. Many endovascular treatments were pioneered at Stanford including thrombolysis for deep venous thrombosis (DVT) and stent-graft repair of thoracic aortic aneurysms.

Our group offers the entire range of vascular and nonvascular image-guided procedures. We are experts in the endovascular treatment of arterial disease from angioplasty and stenting of occluded blood vessels to endograft repair of aneurysms. For venous diseases, we offer state-of-the-art therapy for DVT, varicose veins, and chronic venous occlusion. In the realm of oncology, we specialize in image-guided tumor treatments including chemoembolization, radiofrequency ablation,cryoablation, NanoKnife ablation, and radioembolization. In women's health, we offer a variety of services to alleviate pelvic pain including uterine artery embolization for the treatment of symptomatic fibroids and gonadal vein embolization for pelvic congestion syndrome.

Our advantage, as interventional radiologists, is the ability to use advanced imaging modalities including digital subtraction fluoroscopy, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound to provide the latest endovascular therapies. As pioneers of minimally invasive surgery, we use our techniques to eliminate the need for open surgery and allow shorter recovery times.

Interventional Radiology has been described as the surgery of the new millennium. Our goal is to deliver safe, effective, and compassionate care to all of our patients. Whether you are a referring physician or a patient, we invite you to explore our section and to contact us with questions. We look forward to serving you.

We are a patient-oriented clinically intensive practice that is unusual in the field of interventional radiology. We have an inpatient admitting service, a daily outpatient consultations and follow-up clinic, and an inpatient consult service. In order to provide high-quality patient evaluation and management, we have the following resources:

  • 8 Interventional Radiology Faculty
  • 5 Interventional Radiology Fellows
  • 2 Radiology Residents
  • 3 Nurse Practitioners
  • 2 Nurse Coordinators
  • 3 Medical Assistants
  • 2 Research Coordinators for Clinical Trials
  • 1 Practice Manager

This team functions similar to a surgical sub-specialty service regarding the coordination and delivery of care for patients. In addition, we have the technical and nursing support in the cath lab to operate:

  • 5 Interventional Radiology Suites
  • 1 CT scanner
  • Pre-op and post-op care

Stanford Interventional Radiology has an international reputation for providing innovative image-guided care. We have faculty dedicated to these specific areas:

  • Interventional Oncology
  • Acute and Chronic Deep Venous Thrombosis
  • Pulmonary Embolism/IVC filters
  • Peripheral Arterial Disease
  • Women's Health
  • Dialysis Interventions
  • Venous Access
