Getting to the clinic
Dr Sriram Narayanan practises at the Harley Street Vascular Clinic in the Annexe Block of Gleneagles Hospital, on Napier Road. The nearest MRT is Napier station on the Thomson-East Coast Line (TE12), with Orchard Boulevard station (TE13) also in the wider vicinity; from Napier station the hospital is a short distance away, though many patients find a taxi or ride-hailing service the most convenient option, particularly if walking is difficult or the weather is poor.
Buses run along Napier Road and the nearby roads serving the Tanglin and Orchard fringe. If you travel by taxi or ride-hailing, ask to be set down at the Gleneagles Hospital / Annexe Block entrance, and follow signage to the clinic. Gleneagles provides a paid visitor carpark for those driving. As the area can be busy, allow extra time at peak hours, and consider dropping a less mobile patient at the entrance before parking.
What general vascular surgery covers
Dr Sriram is a vascular and endovascular surgeon whose interests include complex vein surgery and pelvic congestion syndrome, alongside general vascular and endovascular surgery. Vascular surgery deals with conditions of the arteries and veins outside the heart and brain.
- Venous conditions such as varicose veins and chronic venous disease, including complex cases.
- Pelvic congestion syndrome, a venous cause of chronic pelvic discomfort.
- Peripheral arterial disease affecting blood flow to the limbs.
- Deep vein thrombosis and other venous problems.
- Both open surgery and minimally invasive endovascular techniques, chosen to suit the condition.
A feature of modern vascular surgery is the choice between open and endovascular approaches. Many conditions can now be treated through small punctures using catheters and image guidance, while open surgery remains important for certain problems. The right approach depends on the diagnosis, anatomy and the individual.
What to expect at a consultation
A consultation starts with a detailed history of your symptoms, their duration and impact, along with your general health, medications and risk factors. For venous problems the surgeon will ask about leg aching, swelling, skin changes or visible veins; for arterial disease, about walking-related leg pain.
Examination includes inspecting the legs, checking pulses and assessing veins or wounds. Ultrasound scanning of the veins or arteries is commonly used to map the problem, and further imaging may be arranged to plan treatment for more complex cases. You will then discuss the findings and options, which may range from conservative measures and compression to minimally invasive procedures or surgery, with an explanation of what each entails.
Preparing for your appointment
- Photo identification, and any GP or polyclinic referral letter.
- Previous records, scans and reports, including any earlier vascular ultrasound studies.
- A current medication and supplement list, including any blood thinners.
- A written list of symptoms and questions.
- Loose clothing that allows the legs to be examined easily.
- A note of how symptoms affect daily activities, such as standing, walking or sleep.
After your consultation and follow-up
You should leave with a clear understanding of your diagnosis and the proposed plan. Reports from scans are usually available within a few days. Vascular conditions often need review to monitor symptoms, check the results of any procedure and decide on further steps, so follow-up visits are common. Continuity of care is helpful where conditions are long-standing or recur, and you are entitled to seek a second opinion at any time.
Seek urgent attention for a suddenly cold, pale or severely painful leg, sudden significant leg swelling, or signs of a clot, as these can indicate a serious vascular problem needing prompt assessment rather than a routine appointment.
Booking, referrals and fees
As a private specialist, Dr Sriram can usually be seen without a referral, though a GP or polyclinic letter may help with continuity and with subsidies if you are later directed to public services. For eligible procedures, MediSave, MediShield Life and Integrated Shield Plans may apply within set limits, while consultations are generally out of pocket. Because coverage depends on your plan and the specific procedure, confirm fees and claimable items with the clinic in advance.
Common questions
What is the difference between open and endovascular surgery?
Open surgery treats a vessel through a surgical incision, while endovascular techniques work from inside the vessel using catheters and image guidance through small punctures. The choice depends on the condition.
Are varicose veins only a cosmetic issue?
Not always. They can cause aching, swelling and skin changes, and in some cases lead to ulcers, so assessment is worthwhile if they are troublesome.
What is pelvic congestion syndrome?
It is a venous condition that can cause chronic pelvic discomfort. A vascular specialist can assess whether it is contributing to your symptoms.
Will I need a scan before treatment?
Usually. Ultrasound and sometimes further imaging help map the veins or arteries and plan the most suitable treatment.
Can vascular conditions be managed without an operation?
Sometimes. Depending on the diagnosis, options may include lifestyle changes, compression, medication or monitoring, with a procedure considered when these are not enough or the condition specifically requires it.
How long is recovery after a vein or artery procedure?
This varies with the procedure and the individual. Minimally invasive treatments often allow a quicker return to normal activity than open surgery, and the surgeon will explain what to expect and review your progress.
