Vascular Treatment and Embolization FAQs

At Vivid Vascular, we understand that exploring treatment options for vein issues or chronic pain can bring up many questions. We have compiled this comprehensive guide based on the most common inquiries patients have about our minimally invasive procedures, starting with the foundational questions about embolization.

Embolization: Common Questions Answered

What is embolization?

Embolization is a minimally invasive treatment that intentionally blocks blood flow to a specific, abnormal, or problematic blood vessel. Rather than removing tissue through open surgery, we guide a thin catheter through your blood vessels and inject tiny particles, coils, or medical foam to seal off the targeted vessel. According to the Cleveland Clinic, this technique is used to shrink uterine fibroids, treat an enlarged prostate, ease chronic joint pain, and stop abnormal bleeding, all without a large incision.

Most embolization treatments begin with a simple needle puncture, usually in the wrist or groin. Using real time imaging such as fluoroscopy, we navigate a catheter, which is about the width of a strand of spaghetti, through the blood vessels to the source of the problem. Once in position, we release an embolic agent that blocks the blood supply. As the Society of Interventional Radiology explains, cutting off blood flow either shrinks an abnormal growth or stops bleeding, and your body naturally reroutes circulation through healthy vessels.

Embolization is performed by an interventional radiologist, a board certified physician who specializes in image guided, minimally invasive procedures. The Society of Interventional Radiology describes these specialists as physicians who combine advanced imaging with catheter based techniques to treat conditions throughout the body, often serving as an alternative to traditional open surgery. At Vivid Vascular, our procedures are led by a board certified interventional radiologist with decades of experience.

No, embolization is not a major surgery. The Cleveland Clinic classifies it as a minimally invasive, outpatient procedure that requires no large incisions and no stitches, and it typically avoids general anesthesia. Because it is far gentler on the body than open surgery, it involves minimal blood loss, a lower risk of infection, and a much faster recovery. The small puncture site is usually closed with a simple bandage.

Embolization is considered safe and is widely used across many fields of medicine. As the Cleveland Clinic notes, as a minimally invasive approach it generally carries less risk of complication and infection than traditional surgery. As with any medical procedure, there are some risks, such as bruising at the puncture site or a temporary cluster of flu like symptoms known as post embolization syndrome. We carefully evaluate every patient beforehand to confirm the treatment is appropriate.

In most cases you will not need general anesthesia. The Society of Interventional Radiology notes that most embolization procedures are performed with local anesthesia to numb the puncture site along with intravenous medication for sedation and pain relief. This keeps you relaxed and comfortable throughout the procedure while allowing you to go home the same day.

Recovery is typically quick. According to the Cleveland Clinic, most patients rest for a short period afterward and return home the same day. While you should limit strenuous activity and heavy lifting for several days, most people resume their normal routine within about a week. The exact timeline depends on which type of embolization you have.

Embolization treats a wide range of conditions by targeting the blood supply that feeds the problem. As outlined by the Cleveland Clinic, we use it to manage uterine fibroids, an enlarged prostate, varicoceles related to male infertility, knee pain from osteoarthritis, chronic heel pain, and internal hemorrhoids, among other vascular conditions.

Results vary by the condition being treated, but embolization is designed to provide lasting relief. Many patients experience significant, durable improvement in their symptoms, and clinical studies continue to support the long term effectiveness of these procedures across a range of conditions.

Endovenous Laser Ablation (EVLA) for Varicose Veins

What is the endovenous laser ablation procedure?

Endovenous laser ablation is a minimally invasive, nonsurgical treatment for varicose veins. According to the Cleveland Clinic, during the procedure an interventional radiologist uses ultrasound guidance to insert a tiny catheter into the damaged vein, usually through a small puncture near the knee or ankle. A laser fiber is then passed through the catheter to deliver targeted heat, which safely seals the faulty vein shut. Once the vein is closed, your body naturally reroutes blood flow to healthy veins. The entire outpatient procedure takes about an hour, with the laser portion lasting only a few minutes.

Because we use local anesthesia and mild sedation, you will not feel pain during the procedure. A peer reviewed study published in PMC found that the main sensations patients experience are from the tumescent anesthesia injections and the ablation itself, rather than the laser. After the treatment, it is normal to experience mild soreness, tingling, or a pulling sensation along the treated vein as it heals and turns into scar tissue. This discomfort is typically manageable with over the counter pain relievers.

Common side effects are generally mild and resolve within a few weeks. Johns Hopkins Medicine lists bruising, numbness, tingling, and redness or swelling of the vein as typical side effects. Some patients also notice a tight or pulling sensation along the vein, and minor skin color changes can occasionally occur. Inflammation along the sealed vein, known as phlebitis, is also a normal part of the healing process and may peak about a week after the procedure.

While EVLA is considered very safe and carries a lower risk profile than traditional vein stripping surgery, rare complications can occur. Johns Hopkins Medicine notes these may include infection, minor bleeding, nerve damage, skin burns, or blood clots. A clinical study in PMC found that deep vein thrombosis occurred in roughly two percent of cases, making it a very rare outcome.

Recovery is fast, and most patients walk out of the clinic shortly after the procedure. The Cleveland Clinic recommends walking for 30 to 60 minutes immediately following the treatment to promote healthy circulation. You will need to wear compression stockings for a prescribed period and avoid strenuous exercise, heavy lifting, and hot baths for one to two weeks. Most people return to work within a few days, depending on the physical demands of their job.

Leg pain after the procedure is a normal response as the treated vein seals shut and forms scar tissue. A PMC study on EVLA pain confirms that some patients report soreness peaking around seven to ten days post treatment due to localized inflammation along the sealed vein. You might feel a tightening sensation that radiates to the inner thigh, knee, or calf. However, if you experience sudden, worsening pain accompanied by severe swelling or warmth, you should contact a medical professional immediately to rule out a blood clot.

Yes, reviewing before and after photos is a great way to understand the cosmetic and medical improvements EVLA provides. We encourage patients to view our Varicose Vein Treatment gallery to see the typical results of this minimally invasive approach.

Specific Embolization Treatments

What is the difference between a diagnostic angiogram and a vascular embolization?

A diagnostic angiogram is an imaging test used to map out your blood vessels and identify blockages or abnormalities using contrast dye and X rays. Vascular embolization is a therapeutic procedure that actually treats the problem by blocking the abnormal blood vessel. As the Cleveland Clinic explains, while both use a catheter, an angiogram diagnoses the issue and embolization treats it.

Uterine Fibroid Embolization is a non surgical treatment that shrinks fibroids by cutting off their blood supply. According to Johns Hopkins Medicine, tiny particles are injected into the uterine arteries, starving the fibroids of oxygen and nutrients while the uterus remains intact. Patients typically experience cramping and pelvic pain for the first few days, known as post embolization syndrome, but recover much faster than they would from a hysterectomy.

Prostate Artery Embolization is a treatment for benign prostatic hyperplasia (an enlarged prostate). Johns Hopkins Medicine explains that by injecting microscopic spheres into the arteries feeding the prostate, the gland shrinks, relieving urinary symptoms like frequency and poor flow. It carries a lower risk of sexual side effects and incontinence compared to traditional prostate surgery.

GAE stands for Genicular Artery Embolization. It is an innovative, minimally invasive procedure designed to reduce chronic knee pain caused by osteoarthritis. A technical review published in PMC explains that osteoarthritis triggers inflammation that leads to the growth of abnormal small arteries in the knee. GAE blocks these specific arteries, significantly reducing inflammation and providing pain relief for patients who are not ready for a knee replacement.

A varicocele is an enlarged vein in the scrotum that can cause pain and reduce sperm quality. UCSF Radiology confirms that varicocele embolization blocks this faulty vein internally using coils or particles, redirecting blood to healthy veins, and is equally effective to surgical ligation for improving semen parameters and pregnancy rates. It is performed through a single tiny puncture, offering a recovery of one to two days compared to two to three weeks for surgery.

Plantar Fasciitis Embolization is a treatment for severe, chronic heel pain that has not responded to physical therapy or injections. A PMC study on transcatheter arterial embolization found that chronic plantar fasciitis pain is linked to abnormal blood vessel growth in the inflamed tissue. By blocking these tiny vessels, the procedure reduces inflammation and allows the heel to heal naturally, with no incisions or stitches required.

HAE provides relief for symptomatic internal hemorrhoids by reducing their blood supply. A PMC clinical review confirms that HAE is an effective method for treating bleeding hemorrhoids while preserving normal anal function. A catheter is guided to the arteries feeding the hemorrhoidal tissue, and tiny particles are injected to shrink the hemorrhoids and stop bleeding. It is a painless outpatient alternative to surgical hemorrhoid removal.

General Vein and Artery Health

What are the warning signs of clogged arteries in the legs?

Clogged arteries in the legs are a sign of Peripheral Artery Disease (PAD). The Cleveland Clinic identifies the most common warning sign as claudication, which is a cramping pain or heaviness in the calves, thighs, or buttocks that occurs when walking and goes away with rest. Other signs include foot sores that will not heal, a noticeable drop in the temperature of your lower leg, and skin color changes. Smoking and diabetes are the strongest risk factors for PAD.

Venous leg ulcers are chronic wounds caused by poor blood circulation and high pressure in the leg veins. A PMC study on foam sclerotherapy found that treating the underlying faulty veins significantly speeds up ulcer healing and reduces recurrence. Management focuses on reducing venous pressure through compression therapy (specialized stockings or bandages), proper wound care, and addressing the underlying refluxing veins with procedures like foam sclerotherapy or endovenous laser ablation.

Yes, heat from the sun causes your blood vessels to dilate, or expand, to help cool your body down. As vein health specialists note, this natural process makes veins appear more prominent and can temporarily worsen symptoms like swelling and heaviness for individuals with varicose veins. Staying hydrated, elevating your legs, and seeking shade can help manage these summer flare ups.

Varicose and spider veins are incredibly common, affecting a large percentage of adults across all professions. Factors like genetics, age, pregnancy, and spending long hours standing on your feet contribute to vein issues. Fortunately, minimally invasive treatments are widely available to resolve these concerns quickly and effectively. Visit our Varicose Vein Treatment page to learn more.
