PARK AVENUE VEIN SPECIALISTS
HEALTHIER VEINS. BETTER CIRCULATION. IMPROVED QUALITY OF LIFE.
Comprehensive evaluation and personalized treatment for varicose veins, venous insufficiency, leg swelling, and vascular disorders in the heart of Manhattan.
COMPREHENSIVE VEIN & VASCULAR CARE
At Park Avenue Medicine & Surgery, we understand that healthy circulation is essential to overall health, comfort, and mobility.
Venous disorders can cause more than visible changes in the appearance of your legs. Conditions such as chronic venous insufficiency, varicose veins, and venous reflux may contribute to persistent swelling, aching, heaviness, skin changes, and reduced quality of life.
Under the clinical leadership of Tawseef Ahmad Dar, MD, our Vein & Vascular Medicine service emphasizes thorough cardiovascular assessment, diagnostic vascular imaging, individualized treatment planning, and minimally invasive care when clinically appropriate.
Our goal is to identify the underlying cause of your symptoms and help you understand the treatment options best suited to your condition.

CONDITIONS WE EVALUATE
VARICOSE VEINS
Varicose veins are enlarged, twisted superficial veins that commonly develop in the legs.
They occur when blood does not flow efficiently through the venous system, often because the valves within the veins fail to close properly.
Common symptoms include:
Visible enlarged or bulging veins
Aching or throbbing discomfort
Heavy or tired legs
Swelling around the ankles
Burning or itching
Symptoms that worsen after prolonged standing
Nighttime leg discomfort
Although some varicose veins are primarily cosmetic, others are associated with symptomatic venous disease requiring medical evaluation.
CHRONIC VENOUS INSUFFICIENCY
Chronic venous insufficiency develops when the veins have difficulty returning blood from the legs toward the heart.
Over time, impaired venous return may cause increased pressure within the veins, contributing to swelling, skin changes, and discomfort.
Symptoms may include:
Persistent leg heaviness
Swelling of the lower legs or ankles
Aching or fatigue
Skin discoloration
Itching or inflammation
Thickening or hardening of the skin
Venous ulcers in advanced disease
A detailed evaluation, frequently including duplex ultrasound, can help identify the location and severity of venous reflux.
SPIDER VEINS
Spider veins are small superficial blood vessels that appear as fine red, blue, or purple lines beneath the skin.
They are often cosmetic but may coexist with underlying venous insufficiency.
Evaluation helps determine whether treatment should focus on cosmetic concerns, symptomatic disease, or both.
LEG SWELLING & EDEMA
Persistent leg swelling may be related to venous insufficiency, but other conditions can produce similar symptoms.
Potential causes include:
Chronic venous disease
Heart failure
Kidney disease
Lymphatic dysfunction
Medication effects
Deep vein thrombosis
Other vascular or systemic disorders
As an interventional cardiologist, Dr. Dar brings a cardiovascular perspective to the evaluation of lower-extremity swelling, helping identify patients who may require additional cardiac or vascular assessment.
DEEP VEIN THROMBOSIS (DVT)
Deep vein thrombosis occurs when a blood clot develops within a deep vein, most commonly in the leg.
Symptoms may include new swelling, tenderness, warmth, or pain in the affected extremity.
Prompt evaluation is important because a blood clot can sometimes travel to the lungs, resulting in a pulmonary embolism.
Patients with suspected acute DVT require timely medical assessment and diagnostic testing rather than routine elective vein treatment.
ADVANCED VASCULAR ULTRASOUND
NONINVASIVE IMAGING TO UNDERSTAND YOUR CIRCULATION
Vascular ultrasound uses sound waves to evaluate blood vessels and blood flow without exposing patients to ionizing radiation.
Dr. Dar holds the Registered Physician in Vascular Interpretation (RPVI) credential, reflecting specialized qualifications in the interpretation of vascular diagnostic studies.
Depending on the patient's symptoms and clinical indications, testing may include:
Lower Extremity Venous Duplex Ultrasound
Evaluates selected veins in the legs, including assessment for thrombosis, obstruction, and other venous abnormalities.
Venous Reflux and Insufficiency Mapping
Assesses abnormal backward blood flow within the superficial and deep venous systems.
This may include evaluation of:
Great saphenous vein (GSV)
Small saphenous vein (SSV)
Accessory saphenous veins
Deep venous system
Relevant perforator veins
When intervention is appropriate, venous mapping helps identify the anatomy and reflux patterns that may influence treatment selection.
DVT Ultrasound
A focused venous duplex examination may be used to evaluate suspected deep vein thrombosis.
Urgent symptoms require an appropriate same-day or emergency diagnostic pathway.
Lower Extremity Arterial Duplex Ultrasound
Evaluates blood flow through selected arteries of the lower extremities.
This may be appropriate for patients with symptoms suggesting peripheral arterial disease rather than venous insufficiency.
Ankle-Brachial Index (ABI)
A noninvasive assessment comparing blood pressure at the ankles with blood pressure in the arms to help evaluate for peripheral arterial disease.
Additional Vascular Imaging
Depending on clinical indications, additional testing may include renal artery duplex or other vascular studies.
Diagnostic testing is selected according to medical necessity, physician assessment, and the availability of appropriately qualified imaging personnel and equipment.
MINIMALLY INVASIVE VEIN TREATMENTS
MODERN APPROACHES TO SYMPTOMATIC VENOUS DISEASE
Many patients with symptomatic venous insufficiency can be managed without traditional open vein surgery.
Treatment selection depends on the patient's symptoms, ultrasound findings, vascular anatomy, underlying conditions, and preferences.
CONSERVATIVE VEIN MANAGEMENT
Some patients benefit from conservative treatment before or instead of an intervention.
Recommendations may include:
Regular walking and calf muscle activity
Leg elevation
Weight management when appropriate
Avoiding prolonged immobility
Compression stockings when clinically suitable
Management of contributing cardiovascular conditions
Appropriate skin care
Compression therapy may relieve symptoms in selected patients, although it does not eliminate the underlying venous reflux.
ENDOVENOUS ABLATION
TARGETED TREATMENT FOR VENOUS REFLUX
Endovenous ablation is a minimally invasive procedure designed to close selected incompetent superficial veins.
Depending on the clinical findings and treatment method, a physician may recommend:
Radiofrequency ablation (RFA)
Endovenous laser ablation (EVLA)
Nonthermal vein-closure techniques
Other appropriate endovenous interventions
These treatments are intended to redirect blood away from abnormal superficial veins through healthier venous pathways.
Not all patients with varicose veins require ablation, and treatment eligibility depends on the location and severity of reflux, clinical symptoms, and other medical factors.
Specific procedures are offered according to physician qualifications, available equipment, and the capabilities of the treatment facility.
SCLEROTHERAPY
Sclerotherapy is an injection-based treatment used for selected superficial veins, including certain spider veins and varicose veins.
An appropriate solution is injected into the targeted vein, leading to its gradual closure.
Sclerotherapy may be considered alone or as part of a broader treatment strategy, depending on the patient's venous disease.
ADDITIONAL VEIN PROCEDURES
For selected patients, treatment planning may include other minimally invasive techniques to address symptomatic superficial veins.
Our clinical team can discuss appropriate options and arrange treatment with a qualified procedural specialist when necessary.
PERIPHERAL VASCULAR DISEASE
WHEN LEG PAIN IS NOT CAUSED BY VEIN DISEASE
Not all leg pain, swelling, or discoloration originates from the veins.
Peripheral arterial disease (PAD) develops when narrowed arteries reduce blood flow to the lower extremities.
Symptoms may include:
Leg discomfort during walking
Calf pain relieved by rest
Reduced walking tolerance
Cold feet
Nonhealing wounds
Foot pain at rest in advanced cases
As a board-certified interventional cardiologist, Dr. Dar has advanced training in the evaluation and catheter-based treatment of peripheral arterial disease.
A comprehensive assessment may include vascular examination, ABI testing, arterial duplex ultrasound, and additional vascular imaging when indicated.
For patients with clinically significant arterial disease, treatment may involve medications, structured exercise, cardiovascular risk reduction, or selected endovascular interventions.
The distinction between venous and arterial disease is essential because their treatments differ substantially.
WHAT TO EXPECT AT YOUR VEIN CONSULTATION
STEP 1: COMPREHENSIVE MEDICAL EVALUATION
Your physician reviews your symptoms, cardiovascular risk factors, medications, previous procedures, and medical history.
Particular attention is given to leg discomfort, swelling, skin changes, venous disease, and potential arterial abnormalities.
STEP 2: VASCULAR EXAMINATION
A focused examination assesses circulation, visible veins, edema, skin changes, and other relevant clinical findings.
STEP 3: DIAGNOSTIC VASCULAR TESTING
When indicated, duplex ultrasound or other noninvasive vascular testing may be recommended to help establish the diagnosis.
STEP 4: PERSONALIZED TREATMENT PLANNING
Your physician reviews the clinical findings, discusses treatment options, and recommends an individualized management strategy.
This may include conservative treatment, additional testing, or procedural intervention when medically appropriate.
STEP 5: FOLLOW-UP & LONG-TERM VASCULAR HEALTH
Venous disease can progress over time, and some patients may benefit from ongoing monitoring or additional treatment.
Long-term care may also include management of cardiovascular conditions contributing to circulatory symptoms.

FREQUENTLY ASKED QUESTIONS
When should I see a vein specialist?
You may benefit from a vascular evaluation if you experience persistent leg heaviness, aching, swelling, visible varicose veins, or skin changes. New or sudden symptoms may require more urgent assessment.
Are varicose veins only cosmetic?
Not necessarily. Some varicose veins are associated with chronic venous insufficiency and can cause pain, swelling, inflammation, or other complications.
Can ultrasound identify venous insufficiency?
Yes. Duplex ultrasound can evaluate blood flow direction and reflux within selected veins and is a principal diagnostic test for symptomatic superficial venous disease.
Can vein disease cause swollen ankles?
Yes, although ankle swelling can also result from heart, kidney, lymphatic, medication-related, and other conditions. Identifying the cause is important before selecting treatment.
Are minimally invasive vein treatments painful?
Discomfort varies by procedure and patient. Many treatments use local anesthesia, but patients may experience temporary soreness, bruising, or other symptoms afterward.
Will my insurance cover vein treatment?
Coverage depends on the insurance plan, documented symptoms, diagnostic findings, medical necessity, and the proposed procedure. Cosmetic treatments may not be covered.
Can varicose veins return after treatment?
Yes. Although treatment may successfully close targeted veins, venous disease can progress and additional veins may become symptomatic over time.
