Houston Vein & Vascular Center

Memorial Cardiology Associates is proud to introduce the Houston Vein & Vascular Center and the Katy Vein & Vascular Center, now offering our patients the latest in the treatment of varicose veins and vein-related disorders. 

Q: What is Chronic Venous Insufficiency?
A: Chronic Venous Insufficiency (CVI) is a progressive medical condition that causes impairment in the legs ability to properly circulate blood.

Q: What causes CVI?
A: The veins in our legs are responsible for returning blood to the heart but have to do so against the forces of gravity. In order for this to be achieved there are valves within the veins that are designed to allow the steady flow of blood upward towards the heart. In CVI, these valves become dysfunctional and allow constant back-flow (
also called reflux or insufficiency) of blood to the feet causing pooling of blood in the legs and leading to the signs and symptoms associated with CVI.

Q: What are common symptoms of CVI?

  • Bulging varicose veins which may be painful, become red and inflamed (a condition known as phlebitis), or cause internal or external bleeding.

  • Chronic swelling of the legs, ankles, or feet. 

  • Leg fatigue, heaviness, aching, and throbbing. 

  • Burning or itching sensation.

  • Leg cramps, including night cramps. 

  • Restless legs. 

  • Discoloration of the legs including redness and brown pigmentation.

  • Skin breakdown and ulcer formation, which can lead to serious skin infections.

  • Q: What are risk factors for development of CVI?
  •  Pregnancy
  •  Hereditary/family history of venous insufficiency
  •  Occupations that involve prolonged sitting or standing
  •  History of blood clot
  •  Obesity
  •  Age

Q: Are non-invasive treatments available for CVI?

A: While there is no natural cure for CVI, certain measures might help alleviate symptoms. These include exercise, leg elevation, over-the-counter pain medications, and compression stockings. 

Q: Are there any better more definitive treatments for CVI?
A: Yes. For carefully selected patients, we provide excellent minimally invasive options that can result in quick and sustained relief from signs and symptoms of chronic venous insufficiency.

Q:What is Venefit™ Targeted Endovenous Therapy?

A: The Venefit™ procedure is a minimally invasive treatment that uses radiofrequency (RF) energy to effectively treat patients suffering from CVI. A vein specialist inserts a catheter into a diseased vein to provide consistent and uniform heat to contract the collagen in the vein walls, causing them to collapse and close. After the vein is sealed shut, blood is then naturally redirected to healthy veins. 

Q: What is the VenaSeal™ Closure System
A: The VenaSeal™ closure system is a non-thermal, non-sclerosant procedure that uses a proprietary medical adhesive delivered endovenously to close the vein. It represents the latest technology in vein treatment and for some patients may offer advantages over other treatment options. Houston Vein & Vascular Center @ Memorial Cardiology Associates performed the first VenaSeal procedure in the West Houston area.  

Q: How do I know if I'm a candidate for minimally invasive treatment of my veins?
A: Schedule an appointment at 713-464-6006 for an initial vein consultation. Dr. Awar is a Board-Certified Interventional Cardiologist and will perform a comprehensive physical examination and review of your medical history and medications. Because there are many conditions that can mimic the signs and symptoms of CVI, a complete cardiovascular evaluation is essential in ensuring that minimally-invasive vein treatment is the right treatment for you.
