Arterial and Venous Ultrasounds
Ultrasound guided procedures are the core of modern vascular treatments. They require significant training and experience and are always performed first to determine whether a specific artery or vein is open or blocked. This is a noninvasive technique that visualizes the artery with sound waves to measure blood flow through the arteries and veins, allowing the physician to target the problem area and determine the most effective treatment.
Each patient receives a thorough consultation following the ultrasound. If treatment is required, the specialist will explain the most effective treatment options available to increase blood flow to the legs and feet. This may decrease leg pain, reduce or eliminate ulcers and sores, increase mobility and even save the affected limb.
exper-tech-logoAn arterial ultrasound uses sound waves to visualize the artery, measuring the direction and speed of blood cells as they flow through the arteries and veins. This noninvasive technique determines whether a specific artery is open or blocked, and may identify the cause of pain, discomfort, sores or color changes in the legs or feet. It may also help determine the level and degree of Peripheral Arterial Disease.
A venous ultrasound utilizes the same, noninvasive technique to search for blockages in the veins of the legs. These blockages are frequently caused by blood clots, which can become dangerous and life threatening if they break loose and travel to the lungs. The ultrasound may also identify the cause of swelling, redness, pain or cramping in the legs while walking or resting. Ultrasounds are generally an hour in length, and do not require any preparation.
An angiogram is a minimally invasive imaging test used to visualize and diagnose blockages inside the arteries and veins. A thin tube is inserted that injects a special dye, allowing the blood vessels to appear on the X-ray taken immediately after. Fluroscopy imaging captures detailed photographs of the arteries and veins as the dye is introduced into the vessels. If there is a blockage, the radiologist will recommend the most effective treatment options.
Renal Artery Impaired Patients
ProVas uses the most comprehensive set of treatments available in Orange County to protect patients with chronic renal insufficiency during lower extremity angiography/venography and interventions.
- CO2 angiography (venography)
A CO2 angiogram has become a useful diagnostic tool, particularly for patients hypersensitive to iodinated contrast material or with poor kidney function. Carbon dioxide is injected into the blood vessel as an alternative to the iodinated material that is generally used. CO2 angiograms are used for imaging both arterial and venous circulations and also to assist in a variety of endovascular interventions, even in patients without contrast allergies or renal failure.
- Targeted Renal Therapy
Intraoperative administration of a nephro-protective vasodilatory agent directly into the renal arteries during angiography prevents contrast-induced nephropathy.
- Specialized Contrast Agents
Contrast agents with low nephrotoxicity are successfully used in patients with renal impairment.
The highly skilled doctors and nurses of ProVas use these tools and a wealth of experience to achieve limb-saving results in even the most challenging renal impaired patients.
