Vascular Interventional Radiology Division
Interventional radiologists were early innovators in the development of minimally-invasive alternatives to traditional surgical procedures. Among the early advances by interventional radiologists were the invention of angioplasty and the catheter-delivered stent to treat peripheral arterial disease. While these advances have since been widely adopted, the spirit of innovation is fundamental to interventional radiology and the specialty remains committed to providing noninvasive and minimally-invasive solutions to diagnose and treat disease.
Research in Vascular Interventional Radiology
In the spirit of innovation which sparked the development of interventional radiology, the Vascular Interventional Radiology (VIR) Division is dedicated to improving patient care through research. Our research program includes translational research to bring new treatments from the laboratory to clinical practice as well as several ongoing clinical trials. Select clinical trials are listed below:
- The Sentry Clinical Study
The SENTRY IVC Bioconvertible Filter is designed to provide temporary protection to subjects at transient, high risk of pulmonary embolism. Following conclusion of the protection period, The SENTRY filter bioconverts, and filter arms withdraw towards the IVC wall for incorporation, eliminating the need for retrieval.
- A Pilot Study of "OncozeneTM" Microspheres for Intra-arterial Delivery of Doxorubicin for the Treatment of Patients With Unresectable Hepatocellular Cancer
- A Phase III Clinical Trial Evaluating TheraSphere in Patients With Metastatic Colorectal Carcinoma of the Liver Who Have Failed First Line Chemotherapy
The effectiveness and safety of TheraSphere will be evaluated in patients with colorectal cancer with metastases in the liver, who are scheduled to receive second line chemotherapy. All patients receive the standard of care chemotherapy with or without the addition of TheraSphere.
Vascular Interventional Radiology Education
Training the next generation of interventional radiologists is also a priority of the Division and is accomplished through our Accreditation Council for Graduate Medical Education (ACGME) accredited fellowship program. The Fellowship Program provides three fellows a year a rigorous training program consisting of a high volume of clinical cases which is complemented with a formal didactic program, case-based learning, and journal club discussions. The Fellowship Program is in the process of transitioning to the Interventional Radiology/Diagnostic Radiology (IR/DR) Residency Program and will begin enrollment within the next two years.
Patient Care in Vascular Interventional Radiology
Our faculty physicians leverage their expertise in imaging to perform procedures through a precise, targeted and minimally-invasive approach to both diagnosis and therapy. This clinical approach reduces patient risk and pain, and significantly shortens recovery times. We perform more than 10,000 procedures per year at William P. Clements Jr. University Hospital, Parkland Hospital, and Zale Lipshy University Hospital. We also provide comprehensive clinical service through outpatient clinics, consults, and inpatient care.
The VIR Division works closely and collaboratively with other medical and surgical specialties in a multidisciplinary approach to perform a spectrum of interventions. These procedures include venous access; dialysis access interventions; percutaneous biopsies and drainages; placement of nephrostomy tubes and ureteral stents; placement of biliary drains and stents; embolization of uterine fibroids; angioplasty and stent placement for both arterial and venous occlusive disease; placement and retrieval of inferior vena cava (IVC) filters; management of portal hypertension; locoregional therapy of liver, kidney, adrenal and lung cancers with thermal ablation; irreversible electroporation; radioembolization and chemoembolization; and angiography with embolization techniques to treat bleeding.
