Interventional radiology is a minimally-invasive, targeted treatment performed by radiology specialists using imaging guidance. Because the procedures avoid open surgery, they are easier for you, the patient, as there are no large incisions, less risk, less pain, and the procedure is less costly than traditional surgery. They also have shorter recovery times.
Interventional radiologists (IRs) use their expertise in reading X-rays, ultrasound and other medical images to guide small instruments such as catheters (tubes that are just a few millimeters in diameter) through blood vessels or other pathways to treat disease through the skin.
New Haven Radiology offers such interventional radiology treatments as:
- Angiography- to look at arteries throughout the body)
- Angioplasty - once a narrowing in a blood vessel is identified, a small balloon catheter is introduced into the artery from a peripheral site and gently inflated to stretch out the narrowed segment, allowing more blood flow to the affected area.
- Stenting - often performed along with angioplasty, a tiny tube composed of wire mesh (much like a chain link fence) may be inserted to help keep narrowed blood vessels open. In addition to clogged blood vessels, the tiny implant may be used to hold open bile ducts, the esophagus, carotid artery or other pathways in a variety of medical conditions
- Thrombolysis/Thrombectomy - patients with an acute blood clot in an artery, vein or arterial bypass graft may be a candidate for one or more clot removal methods. Thrombolysis involves infusing a special medication directly to an area of blood clot in an attempt to break it up and restore blood flow. Thrombectomy is similar, but involves a mechanical device used to break up and extract blood clots. Oftentimes, a combination of both is used to alleviate clots.

The section of Interventional Radiology is staffed with three Board Certified, subspecialty trained radiologists each with over 17 years of experience in their field. These physician's particular interests and focus overlap such that the full spectrum of image guided diagnosis and treatment is offered. In addition, the radiologists are supported by an experienced technical and nursing staff and a full time Physician's Assistant dedicated to patient evaluation, treatment and follow-up. Because of being part of New Haven Radiology, the Interventional Section has constant and immediate access to diagnostic radiology experts for consultation in all areas of medical imaging. Our Interventional nursing staff provides patient education, pre and post procedural evaluation and follow-up as well as provide patient support and sedation as needed. Each interventional procedure is attended by one of our dedicated IR trained nurses.
Typical day to day procedures include all types of venous access, such as implantable ports, PICC lines, medical Hickman catheters, and dialysis access catheters. In addition, we are able to diagnosis and treat malfunctioning dialysis access fistulas and grafts like most of our procedures on an outpatient basis. All types of vascular disease, both arterial and venous can be evaluated and possibly treated in the same setting. This would include the newer thrombolytic and mechanical treatment for deep venous thrombosis, IVC filtration, treatment of varicose veins, arterial angioplasty and stenting as needed.
Newer techniques to treat uterine fibroid disease is offered as an alternative to hysterectomy in selected patients. Endourologic techniques to remove kidney stones, relieve hydronephrosis, stenting obstructed ureters due to cancer, etc, are routinely done as well as biliary decompression and reconstruction procedures.
Using CT and Ultrasound guidance, we are able to perform biopsies in all organ systems, again on an outpatient basis with nursing support for the comfort and safety of your patients. All types of abnormal fluid collections can be managed by image guided catheter therapy. Intra-arterial therapies for malignancies can be performed in carefully selected patients in concert with the referring oncologist and surgeon.
Many types of pain management procedures are offered such as vertebroplasty for spinal compression fractures, epidural steroid injections and facet blocks. In addition to spine procedures, we are able to provide sophisticated neurovascular solutions to intra cerebral aneurysms, AVMs etc.
For nutritional support in patients with strokes or other situations requiring enteral feeding, we offer flouroscopic gastrostomy tube or gastrojejunostomy placement on either an inpatient or outpatient basis.
Finally, we would be happy to see your patients in consultation for any of these procedures, allowing the referring physician to remain in control of their patient's care while having quick, experienced interventional radiology techniques available in a timely compassionate fashion.
