Texas Endovascular - Clear Lake is an outpatient interventional radiology clinic at 390 East Medical Center Blvd, Webster, TX 77598, less than half a mile from HCA Houston Healthcare Clear Lake. Dr. AJ Valenson, a double board-certified interventional radiologist who sees patients in English and Spanish, diagnoses and treats vein disease here, including varicose veins, spider veins, and chronic venous insufficiency. Consultation, ultrasound, treatment, and follow-up all happen in this clinic.
Vein disease, also called chronic venous insufficiency (CVI), develops when the valves in your leg veins weaken or become damaged. Healthy valves keep blood moving up toward your heart against gravity. When they fail, blood pools in the legs instead of flowing normally.
CVI is one of the leading causes of varicose veins, leg swelling, skin changes, and chronic leg discomfort. Without treatment, vein disease often progresses over time, so early evaluation is important for protecting your long-term vascular health. Learn more about vein disease →
If your symptoms continue despite compression stockings, exercise, or elevating your legs, it may be time for an evaluation. Consider seeing a vein specialist if you have:
Sudden swelling, pain, warmth, or redness in one leg can be a sign of a blood clot and needs prompt medical attention.
Every plan starts with an ultrasound vein evaluation to find which veins are causing your symptoms. Your physician then recommends one or more outpatient treatments. Each is performed through a tiny catheter or needle puncture using ultrasound guidance, without traditional surgery.
Most patients return home the same day and resume normal activities within 24 to 48 hours.

Dr. AJ Valenson, a double board-certified interventional radiologist and the clinic's lead provider, sees vein patients in Clear Lake. He is fluent in English and Spanish. Several of our physicians rotate between clinics, so ask when you call if you would like a specific doctor.
Our Clear Lake clinic offers ultrasound vein evaluation, radiofrequency ablation, ultrasound-guided foam sclerotherapy, ambulatory phlebectomy, and cosmetic sclerotherapy. Consultation, treatment, and follow-up all happen in this clinic.
Varicose veins form when weakened vein valves let blood flow backward and collect, which stretches the vein. Family history, age, pregnancy, extra weight, and long periods of standing or sitting all raise the risk.
Many varicose veins are not dangerous. Untreated vein disease can progress, though, and may raise the risk of skin changes, slow-healing ulcers, bleeding, and blood clots. An ultrasound evaluation shows whether your veins need treatment.
It depends on which veins are affected and how severe the problem is. After an ultrasound evaluation, your physician may recommend radiofrequency ablation, sclerotherapy, ambulatory phlebectomy, or a combination.
Vein procedures are performed with local numbing, and most patients report only mild discomfort. Your care team explains what to expect before, during, and after your procedure.
Most patients go home the same day and return to normal activities within 24 to 48 hours. You can usually walk out and resume light activity right away.
Medicare and most major insurance plans cover vein treatment when it is medically necessary. Treatment done for appearance only, such as cosmetic sclerotherapy for spider veins, is usually not covered. Our team verifies your benefits and explains what you can expect to pay before your visit is scheduled.
Most patients can schedule directly without a physician referral. Some insurance plans require one, so check your plan or ask our team when you call and we can verify for you.
