Varicose Veins Overview
What Are Varicose Veins?
Oxygenated blood delivers oxygen to cells and then returns to the heart in deoxygenated form so it can be pumped into the lungs to collect more oxygen. This vital transport occurs via your veins. When excess pressure builds in the veins near the surface of your skin (superficial veins), varicosities develop, known as varicose veins.
Studies estimate that 20% of people will develop varicose veins in their lifetime, and the prevalence is even higher among women.
- Varicose veins are most common on the calves and inner thighs, but they can occur anywhere on the body. These unhealthy veins are the result of elevated blood pressure in other veins located deeper in the leg.
- Certain risk factors increase the chance of developing varicose veins, like pregnancy, weight gain, aging, family history of vascular disease, and prolonged sitting or standing at work.
- There are several minimally invasive treatments and simple lifestyle adjustments to relieve varicose veins without downtime. Treating varicose veins not only provides relief, it also enhances your appearance and prevents serious complications.
- Varicose veins appear swollen, bulging, raised, or enlarged, and can also be twisted or tortuous (full of twists and turns). They are typically red, blue, or purple.
- Chronic venous insufficiency is the underlying disease that commonly leads to varicose veins.
What Causes Varicose Veins?
The veins in the legs are able to pump deoxygenated blood back up toward the heart with the help of valves that close to prevent backflow. Certain conditions cause these valves to malfunction, which allows blood to pool in the veins or travel backward, rather than continuing upward. This causes engorgement and increased pressure which generates varicose vein formation. Those with a history of blood clots or venous trauma are more susceptible since weaker vein walls are easier to break, prompting varicose veins to develop. Since the leg veins have to work against gravity, pumping blood upwards, they’re the most likely location for varicose veins to form. Inflаmmаtіоn оf thе vеіnѕ (phlebitis) and соngеnіtаl abnormalities are other less common reasons varicose veins develop.
What Are the Symptoms of Varicose Veins?
While sometimes visible, varicose veins don’t always produce symptoms. Here are signs to look for:
• Bulgіng, tortuous, or enlarged veins
• Swelling in ankles or feet
• Leg cramping or achiness
• Sensation of hеаviness, more pronounced at night
• Restless legs syndrome
• Spider veins in the area of varicosity
• Stasis dermatitis- a red dry, itchy, venous eczema on the skin
• Hard, lumpy deposits of fat beneath the skin (Lіроdеrmаtоѕсlеrоѕіѕ)
• Discoloration in the lower extremities presenting as blue or brown skin.
Who Is Affected by Varicose Veins?
Anyone can develop varicose veins at any age, particularly those with a family history of vein disease or a job that requires extensive standing or sitting. Teachers, truck drivers, nurses, and those with a desk job are at increased risk. However, varicose veins are more prevalent in women following menopause or pregnancy and men over age 50.
Varicose Vein Treatments:
There are many treatment options for vаrісоѕе veins, the best of which is determined by your individual condition. Doctors will assess the size and location of the damaged vein, as well as your symptom profile and any skin issues (ulcers, swelling, eczema, dermatitis) to devise the best treatment plan.
Potential Treatments Include:
• Sclerotherapy: destruction of the damaged vessel by liquid or foam injection
• Ablаtіоn: elimination of venous abnormalities via laser or radiofrequency
• Surgеrу: phlebectomy, a surgical “stripping” of offending veins
• Elеvаtіоn of legs when sitting for long periods or sleeping
• Compression or support ѕtосkіngѕ
NOTE: For most patients, Sclerotherapy and Radiofrequency are the best choices for varicose vein treatment.
Is Varicose Vein Treatment Safe?
Varicose vein treatment is a simple, safe process for most patients. Minimally invasive therapy, developed in the early 2000s, dramatically improved the risk profile for vein treatment. It’s essential to choose a board certified doctor who specializes in these minimally invasive vein treatments to mitigate risk. Our highly trained physicians customize treatment to align with your unique anatomy and medical history. Our treatment modalities are specifically tailored to each individual.
How Does a Doctor Diagnose Varicose Veins and Venous Insufficiency?
A qualified doctor will take a complete medical history, noting both the appearance of your legs and any accompanying symptoms. A good vein physician will also ask questions to determine your health goals and personal preferences. Since varicose veins can be asymptomatic, your doctor will determine whether a duplex ultrasound scan is necessary to check for venous insufficiency. This scan reveals a full picture of your individual venous pathways, locating blood clots, symptomatic veins, and their connection to additional veins to identify potential issues.
