The Vascular Laboratory at Danbury Hospital is one of just 30 in the U.S. to be accredited by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL) in all five areas of vascular testing, including:
- Carotid duplex
- Transcranial Doppler (TCD)
- Venous duplex
- Arterial testing
- Abdominal vascular duplex
This ranks our Vascular Laboratory among the top two percent in the nation for high-quality testing for vascular disease.
Danbury Hospital’s vascular surgery team has expertise in the diagnosis and treatment of peripheral vascular disorders, including:
- VNUS Closure®: This catheter-based technique utilizes radiofrequency to seal shut the vein, clinically proven to cause less pain and bruising than laser or surgical treatments.
- Microphlebectomy: Larger veins may be removed through tiny skin punctures. This outpatient procedure uses small incisions that do not require stitches.
- Sclerotherapy: Small veins can be treated with injection of a detergent-type agent, which reroutes blood to healthier veins.
- Carotid Duplex: Ultrasound is used to evaluate the carotid arteries located in the neck that feed the brain with blood. Gel is applied to the skin of the neck. A transducer is then placed on the gel-covered areas to obtain images and evaluate the blood flow in the arteries. Your doctor may order this test if you have physical examination findings or symptoms that suggest that you may have a blockage in the carotid artery.
- Transcranial Doppler (TCD): This exam evaluates the blood vessels that supply the brain within the skull. It is performed with a small transducer that is placed on the skin of the face and head.
- Venous Duplex: Also called a Doppler examination, ultrasound is used to evaluate the veins that carry blood to the heart from the legs or arms. Gel is applied to the skin of the legs or arms. A transducer is then placed on the gel-covered areas to obtain images and evaluate blood flow in the veins. Your doctor may order this to evaluate the cause of pain or swelling in your legs or arms.
- Arterial Testing
- Arterial Duplex: Also called a Doppler examination, ultrasound is used to evaluate the arteries that feed the arms and legs with blood. Gel is applied to the skin of the legs or arms. A transducer is then placed on the gel-covered areas to obtain images and evaluate the blood flow in the arms or legs. Your doctor may order this test to evaluate the cause of pain in the leg muscles with walking.
- Arterial Pressures and Waveforms: Ultrasound and blood pressure cuffs are used to evaluate the arteries that supply the arms and legs with blood. Several blood pressure cuffs are placed in various locations on the legs or arms. When inflated, the cuffs provide blood pressure readings as well as waveforms. This test will locate areas of blockage with in the arteries. Your doctor may order this test to evaluate the cause of pain in the leg muscles with walking.
- Abdominal Vascular Duplex: Also called a Doppler examination, ultrasound is used to evaluate the blood vessels that bring blood to and away from the abdominal organs. The aorta, the main blood vessel in the body, is also imaged to evaluate for aneurysms and or blockages. Gel is applied to the abdomen. A transducer is then placed on the gel-covered areas to obtain images and evaluate blood flow in the arteries and/or veins.
- Abdominal aortic aneurysm repair
- Thoracic aneurysm repair
- Carotid endarterectomy
- Lower and upper extremity arterial revascularization
- Renal and visceral arterial revascularization
- Vascular exposure for spine procedures
- Percutaneous Transluminal Angioplasty (PTA) and Stenting: Following a small needle puncture in an artery in your arm or groin, a long, thin, flexible tube called a balloon-tip catheter is inserted. The catheter is guided through the arteries to the location of the blockage, where it is inflated. The balloon pushes the plaque in the artery against the artery walls, widening the vessel. At this point, if the result is not optimal, your vascular surgeon may place a tiny mesh-metal tube, called a stent, into the narrowed artery to prop it open.
- Endovascular Aneurysm Repair (EVAR): This minimally invasive procedure corrects abdominal aortic aneurysms in less time than traditional open repair and can also be done under local or spinal anesthesia. Small incisions are made in both groins for image-guided placement of catheters containing self-expanding covered stents. Benefits of this procedure include a dramatically shorter hospital stay (2-3 days vs. 7-10 for traditional surgery) and a quicker total recovery time (one week vs. 6 weeks).
- Thrombolytic (Lytic) Therapy: Arterial blockages in the arms, legs or can often be reopened with the use drugs called lytic agents. Administered through a small catheter in the artery, lytic agents dissolve the clot, avoiding the need for surgery. Lytic therapy can also be used to dissolve clots in the large veins of the arms and legs in order to preserve vein valve function and prevent pulmonary embolism.
