Vascular Surgery / Stony Brook Vascular Center

Our vascular surgeons have been recognized for their clinical excellence by selection for inclusion in the Castle Connolly Guide, Top Doctors: New York Metro Area, representing the top 10% of physicians in the New York Metropolitan area, as well as by inclusion in the Consumers' Research Council of America Guide to America's Top Surgeons.

The Society for Vascular Surgery's Vascular Quality Initiative (SVS VQI) has awarded Stony Brook Medicine three stars — the top rating — for its active participation in the Registry Participation Program. This is the second year in a row Vascular Surgery has been awarded three stars and recognized for their focus on continuous improvement in patient care.

Due to the exceptional care of our vascular surgeons,  the Stony Brook Aortic Center is the first facility on Long Island to have a patient receive a new stent graft device that has just been approved for the treatment of aortic dissections. (read more)

The Stony Brook Vascular Center, is a spacious facility built to support our growing clinical practice. It is designed to offer our patients clinical evaluation with the most advanced diagnostic tests and state-of-the-art procedure rooms for minimally invasive office-based procedures.

Our team provides specialized services for a wide variety of circulatory disorders. Our surgeons perform reconstructive procedures for occlusive and aneurysmal diseases. They have special expertise in:

Aneurysms and strokes can strike suddenly and without warning. That's why it's best to identify and treat underlying causes before symptoms appear. Learn about our vascular disease screenings today!

Demonstrating our commitment to providing the latest advances in patient care, our program in minimally invasive endovascular surgery offers a scope of diagnostic and treatment options which are unique in Suffolk County. At our Center for Vein Care — fully accredited by the Intersocietal Accreditation Commission — with offices in Centereach, Commack, Patchogue, Hampton Bays, and Southampton, our vascular specialists provide treatment for:

  • Acute deep vein thrombosis
  • Chronic venous thrombosis
  • Pelvic congestion syndrome
  • Varicose and spider veins
  • Venous ulcerations

Our specialists use the latest surgical and non-surgical techniques to treat varicose veins and spider veins of the leg, including new minimally invasive "endovenous" techniques that let patients get back to their normal activities in usually just a couple of days. No general anesthesia or hospitalization is required. Learn more on the Center for Vein Care's Facebook page.

For the evaluation and treatment of chronic leg and foot ulcers, they provide comprehensive wound care management.


To provide the best possible patient care, our Vascular Surgery Service uses the Non-Invasive Vascular Laboratory of Stony Brook University Hospital. The Non-Invasive Vascular Laboratory houses a wide variety of state-of-the-art equipment, including Duplex scanners and transcranial Doppler units, used not only as aids in the diagnosis of circulatory disorders, but also in the follow-up of a large number of outpatients.

Our Non-Invasive Vascular Laboratory is complemented by an excellent special procedures division of the radiology department, which likewise has the latest in angiography equipment and CT scanners, at University Hospital.

The special procedures division provides service in all the techniques of interventional radiology, including balloon dilatation (angioplasty), invasive pressure monitoring, and therapeutic embolization.

The Non-Invasive Vascular Laboratory at Stony Brook Medicine performs sophisticated non-invasive cerebral, peripheral, and abdominal vascular studies. Our lab is fully accredited by the Intersocietal Accreditation Commission (IAC) (formerly, Intersocietal Commission for the Accreditation of Vascular Laboratories, or ICAVL).

Meeting the high standards set by the ICA demonstrates our lab's commitment to excellence and quality assurance in vascular testing.

Benefits

Non-invasive vascular evaluations offer a number of advantages. These sophisticated tests are painless and can document the presence, location, and severity of arterial and venous vascular disease. In addition, the non-invasive nature of the exam greatly reduces patient risk and enhances patient comfort when compared to invasive diagnostic procedures. These tests are also cost-effective, an important consideration in today's healthcare environment.

Service-Oriented Approach

The Non-Invasive Vascular Laboratory takes a "service-oriented" approach to physicians and patients. This is exemplified by:

Rapid Report Turn-Around Time
Positive preliminary reports are immediately communicated to the referring physician either by telephone or fax. Final reports interpreted by our distinguished physician panel are mailed to the referring physician's office within 48 to 72 hours of the study. Our physicians are available for consultation regarding a study during hours of operation.

Sensitivity to Patient Needs
Each patient referred to the Non-Invasive Vascular Laboratory is treated as an individual with specific needs. Vascular technologists obtain a complete problem-focused history, thoroughly explain the procedure, and help the patient relax by carefully describing the test as it is being performed.

Comprehensive Evaluation
Each comprehensive vascular evaluation includes a complete problem-focused history, performance of the test with hard copy and/or video recording of the data, physician-interpreted results and readily available reports.

State-of-the-Art Technology

The Non-Invasive Vascular Laboratory features the latest technology available in the field. This includes:

Direct Studies
Colorflow duplex ultrasonography is utilized to evaluate the arterial and venous systems. This technology combines three ultrasound modalities:

1. Two-dimensional B-mode ultrasound imaging in gray scale provides anatomic information about the vessels of interest. The presence or absence of atherosclerotic plaque or thrombus is detected using this modality.

2. Doppler ultrasound provides physiologic information about blood flow in the vessel. Using this modality, a Doppler velocity spectral analysis is obtained, which can determine whether plaque or thrombus is hemodynamically significant and compromising blood flow.

3. Colorflow ultrasound provides the ability to quickly visualize blood flow and demonstrate the degree of vessel obstruction.

Indirect Studies
Indirect studies also play a key role in non-invasive vascular evaluations. These tests include digital plethysmographic analysis for evaluation of perfusion, spectral waveform analysis for characterization of the Doppler velocity signals, and segmental Doppler systolic pressures. The Non-Invasive Vascular Laboratory performs the following procedures:

  • Arterial Doppler and pulse volume recorder evaluation with or without exercise testing
  • Digital arterial studies
  • Duplex ultrasonographic evaluation of hemodialysis access devices
  • Evaluation of abdominal aortic aneurysm with duplex ultrasonography
  • Evaluation of temporal arteritis
  • Extracranial cerebrovascular duplex ultrasonography
  • Graft imaging to assess patency status after arterial bypass
  • Hyperemia evaluations prior to hemodialysis access
  • Intracranial cerebrovascular duplex ultrasonography
  • Intravascular completion duplex ultrasonography
  • Mesenteric arterial duplex ultrasonography
  • Renal artery duplex ultrasonography
  • Supine and standing lower extremity venous duplex ultrasonography
  • Ultrasound-guided thrombin injection of femoral pseudoaneurysm
  • Upper and lower extremity arterial duplex ultrasonography
  • Upper and lower extremity vein mapping
  • Upper extremity venous duplex ultrasonography
