A Vascular and Endovascular Surgeon treats disorders of arteries, veins, and lymphatic vessels across the body. This includes conditions like aortic aneurysms, carotid artery disease, peripheral arterial occlusive disease, varicose veins, DVT, diabetic foot problems, and traumatic vascular injuries. They use both open surgical techniques and minimally invasive options like angioplasty, stenting, and laser ablation to restore blood flow, prevent limb loss, and ensure safe long-term vascular health.

You should consult a vascular specialist if you have leg pain while walking, non-healing foot wounds, varicose veins, numbness, discoloration, swelling, sudden leg pain, or a history of diabetes or smoking. People with high blood pressure, high cholesterol, or previous strokes should also seek screening. Early consultation helps diagnose hidden vascular blockages, prevents complications like gangrene or stroke, and allows timely intervention using advanced endovascular methods.

Peripheral arterial disease occurs when arteries in the legs become narrowed or blocked due to plaque buildup, reducing blood flow. It commonly causes leg pain while walking, cold feet, slow-healing wounds, or numbness. PAD is especially common in diabetics and smokers. If untreated, it can progress to critical limb ischemia and even amputation. Early diagnosis through Doppler studies and treatment with angioplasty, stenting, or bypass surgery can restore circulation.

Varicose veins are managed using modern minimally invasive treatments that avoid major surgery. Procedures like Endovenous Laser Treatment (EVLT), VenaSeal glue therapy, sclerotherapy, and radiofrequency ablation close faulty veins safely with minimal discomfort. Most treatments are walk-in/walk-out, require only a few minutes, and allow patients to resume normal activities quickly. Dr. Narasimhan pioneered day-care laser ablation in South India, offering highly effective and cosmetically superior outcomes.

Diabetic foot ulcers develop due to reduced blood flow, nerve damage, and delayed healing in diabetic patients. Poor circulation increases the risk of infection and limb loss. Management includes restoring blood flow using angioplasty or bypass surgery, wound debridement, infection control, and advanced dressings. With a 98% limb-salvage rate, Dr. Narasimhan focuses on early detection, precision procedures, and comprehensive foot care to prevent amputations and improve long-term mobility.

Carotid artery disease occurs when arteries supplying blood to the brain become narrowed due to plaque. It can cause transient ischemic attacks, stroke, or sudden neurologic symptoms. Timely diagnosis through ultrasound or CT angiography is essential. Treatment options include carotid endarterectomy or stenting, depending on severity. Safe and early intervention prevents stroke and improves long-term brain health, especially in patients with hypertension, diabetes, or smoking history.

An aortic aneurysm is a dangerous bulge in the largest artery that can rupture if untreated. Screening is important for older adults, smokers, and those with family history. Treatment is based on size and risk, ranging from regular monitoring to minimally invasive Endovascular Aneurysm Repair (EVAR) or open surgical repair. With advanced training across three countries, Dr. Narasimhan provides both approaches with excellent safety and recovery outcomes.

DVT occurs when a blood clot forms in deep veins of the legs, causing pain, swelling, and heaviness. If the clot travels to the lungs, it can cause a life-threatening pulmonary embolism. Diagnosis is done with Doppler ultrasound. Treatment includes blood thinners, catheter-directed thrombolysis, endovascular clot removal, and stenting for severe cases. Early management prevents long-term complications like post-thrombotic syndrome and chronic leg swelling.

Vascular injuries from accidents, fractures, or penetrating wounds require urgent attention to prevent limb loss or life-threatening bleeding. Treatment may include vessel repair, grafting, or endovascular stenting depending on the injury. Dr. Narasimhan’s experience with trauma-related vascular repairs ensures rapid restoration of blood flow, meticulous surgical technique, and close follow-up. Early intervention reduces complications, preserves limb function, and supports optimal recovery.

Endovascular procedures are minimally invasive vascular treatments performed through tiny needle punctures instead of open surgery. Using advanced imaging, catheters, balloons, and stents, surgeons can treat blockages, aneurysms, or vascular malformations with faster recovery and minimal pain. Because these procedures avoid large incisions, they are safer for elderly patients and those with multiple health conditions. Dr. Narasimhan’s hybrid OT facility ensures precision and world-class outcomes.

Vascular access surgery creates a reliable blood vessel connection for patients needing long-term dialysis or frequent medical infusions. This includes AV fistulas, grafts, and catheter insertions. Successful access ensures efficient dialysis, prevents complications, and avoids repeated needle trauma. As vascular access procedures require precision and long-term monitoring, being treated by an experienced vascular surgeon like Dr. Narasimhan significantly improves durability and patient comfort.

Amputation prevention depends on early diagnosis, restoring blood flow, controlling infection, and continuous monitoring. For diabetics and patients with severe PAD, timely angioplasty, stenting, or bypass surgery can save the limb. Dr. Narasimhan’s 98% limb-salvage success is based on advanced imaging, aggressive revascularization, and comprehensive foot care. Community screening camps and early intervention strategies help detect disease early and prevent avoidable amputations.
