A dialysis fistula or graft is more than a vein in the arm. For someone on haemodialysis, it is their lifeline.

If the access becomes difficult to needle, dialysis flow seems poor, machine pressures are high, bleeding takes longer to stop, the arm becomes swollen, or the fistula starts looking very enlarged, painful or infected, it should not be ignored.

These changes can be signs of narrowing, blockage, aneurysm formation, infection, or poor flow through the access. If a fistula clots suddenly, dialysis can be interrupted and a temporary catheter may be needed, which carries its own risks.

The important point is that many dialysis access problems can be assessed before the access completely fails. A vascular assessment may include duplex ultrasound, fistulogram, balloon angioplasty, stenting in selected cases, or surgical revision depending on the exact problem.

At Andrew Choong Vascular Surgery, Mount Elizabeth Novena, Singapore, dialysis access and fistula problems are assessed with the aim of preserving reliable access where possible and avoiding preventable disruption to dialysis.

If your fistula or graft is changing, difficult to use, repeatedly troublesome during dialysis, or has clotted before, arrange early vascular review.

Bleeding from varicose veins can look frightening, but there are simple first steps: lie down, raise the leg, and apply firm direct pressure with a clean cloth or dressing.

If bleeding is heavy, does not stop, you feel faint, or you are on blood thinners, seek urgent medical help.

But even if it settles, do not ignore it. Bleeding can be a sign of underlying venous reflux or high pressure in the superficial veins. A venous duplex ultrasound helps identify the source and guide whether treatment is needed to reduce the risk of recurrence.

What is the difference between an **aortic aneurysm and an aortic dissection**?

They are often confused, but they are not the same condition.

An **aortic aneurysm** is an abnormal enlargement or dilatation of part of the aorta. Over time, the weakened section of the aortic wall can continue to enlarge and may eventually rupture.

An **aortic dissection** occurs when a tear develops in the inner lining of the aorta. Blood then passes into the wall of the aorta and separates its layers, creating what is known as a false lumen.

In simple terms:

**Aneurysm = enlargement of the aorta.**
**Dissection = a tear within the wall of the aorta.**

You can have an aortic aneurysm without a dissection, and an aortic dissection can occur even when the aorta is not severely enlarged.

Both conditions can potentially result in **aortic rupture**, but their presentation, urgency and treatment can be very different.

Understanding the difference is particularly important if you or a family member has been diagnosed with an abdominal aortic aneurysm, thoracic aortic aneurysm or aortic dissection.

Dr Andrew Choong is a vascular and endovascular surgeon in Singapore with a specialist interest in complex aortic disease.

Today is Aortic Dissection Awareness Day.

Aortic dissection is a life-threatening emergency involving the aorta, the main blood vessel carrying blood from the heart to the body.

It can cause sudden severe chest, back or abdominal pain, but it can also mimic a heart attack, stroke, fainting episode, abdominal problem, limb circulation problem or sudden collapse.

If symptoms are sudden, severe or unusual, especially in someone with high blood pressure, a known aneurysm, previous aortic disease, connective tissue disease, bicuspid aortic valve or a family history of aortic problems, the aorta must be considered.

Think Aorta. Get a contrast CT. Do not wait at home with sudden severe symptoms.

🚨 Sudden severe chest, back or abdominal pain? Think Aorta. Get a contrast CT.

Aortic dissection is one of the vascular emergencies that patients and doctors must not ignore.

It happens when a tear develops in the inner layer of the aorta, the main blood vessel carrying blood from the heart to the body. Blood can then track into the wall of the aorta, and this can become life-threatening very quickly.

The classical warning sign is sudden, severe chest, back or abdominal pain. Some patients describe it as tearing, ripping, or the worst pain they have ever felt.

But importantly, aortic dissection is also a great clinical mimicker. It does not always look textbook. It can present like a heart attack, stroke, fainting episode, abdominal problem, limb circulation problem, or simply sudden collapse.

Tomorrow is Aortic Dissection Awareness Day. The key message is simple: early recognition matters because delay can be fatal.

If symptoms are sudden, severe or concerning, do not watch them at home. Seek urgent emergency assessment.

Despite loving guitar, a busy surgical practice - and a new clinic - haven’t left nearly enough time to play. Even with a guitar at the clinic, I’m always looking for ways to make music a little more possible on the go.

I’ve long been obsessed with travel guitars, but wanted something genuinely portable: a truly capable instrument you can throw in a backpack and take anywhere, without compromising the feel of a proper guitar.

Honoured to have designed the HORNET MS7 alongside master luthier Archie Limsiaco of Limparch Design - an instrument made to travel, practise, and hopefully help me become a better player along the way.

A little more right-brain creativity to balance the left-brain work. Now I just need to find the time to practise. 🎸

World Health Organization (WHO) is a useful reminder that safe vascular care starts before treatment.

It starts with listening carefully, checking pulses, reviewing scans properly, and asking the right question: what problem are we trying to prevent or treat?

For some patients, the safest plan may be surveillance and risk-factor control. For others, it may be angioplasty, stenting, endovascular repair, open surgery, or urgent clot treatment.

The key is not simply choosing the newest or least invasive option. Safe care means choosing the right treatment for the right patient at the right time.

What does endovascular treatment mean?

In simple terms, it means treating blood vessels from the inside, usually through a small puncture in an artery or vein.

Through that access, vascular surgeons can use wires, catheters, balloons, stents, stent-grafts and clot-removal devices to treat different blood vessel problems.

For an aneurysm, a stent-graft may be placed inside the artery to exclude the aneurysm from the circulation — like a pipe within a pipe.

For narrowed or blocked arteries, balloons and stents may be used to open the vessel and keep blood flowing.

For selected blood clots, including deep vein thrombosis or pulmonary embolism, specialised endovascular devices may be used to remove clot in appropriate cases.

But “keyhole” does not mean minor, and it does not mean suitable for everyone. The right treatment depends on the scan findings, the anatomy, the clinical risk, and what problem we are trying to solve.

This is part of a new “tools of the trade” series explaining the techniques used in modern vascular and endovascular surgery.

Poor leg circulation is not something to guess about.

Peripheral artery disease, or PAD, happens when the arteries supplying the legs become narrowed or blocked. One of the classic symptoms is pain in the calf, thigh or buttock when walking, which improves after resting. But PAD can also show up as cold feet, numbness, weak pulses, slow-healing wounds, ulcers, gangrene, or pain in the foot even at rest.

When you see a vascular surgeon for suspected PAD, the first question is not simply, “Do I need a procedure?”

The better question is, “How bad is the blood flow, where is the blockage, and what treatment matches the problem?”

Assessment usually starts with the story: walking distance, pain pattern, diabetes, smoking history, kidney disease, heart disease, previous angioplasty, stents or bypass surgery. Then comes examination of the legs and feet, including pulses, skin changes, wounds, temperature and signs that the foot may be at risk.

Tests may include bedside pressure measurements, vascular ultrasound, and sometimes CT angiography to map the arteries more clearly.

The scan matters because different patients need different plans. Some need exercise, medication and risk-factor control. Some need angioplasty or stenting. Some need bypass surgery. Some need urgent treatment because a wound, ulcer or toe is at risk.

The goal is not just to “open an artery”. The goal is to match treatment to symptoms, scan findings, wound risk and overall health.

If you have leg pain when walking, poor circulation, or a foot wound that is not healing, get the blood flow assessed properly.

Varicose veins can look similar on the surface, but the underlying problem may be very different.

The visible veins are often only the end result. The real issue may be deeper, where valves inside the veins are not working properly and blood is flowing backwards. This is called venous reflux.

That is why treatment should not be chosen from a photograph or from appearance alone.

A proper vascular ultrasound scan helps identify where the reflux is coming from, which veins are involved, and whether treatment should be directed at the deeper source of the problem rather than only the visible veins on the surface.

This matters because two people can have varicose veins that look almost identical, but their scan findings can be completely different. One person may be suitable for endovenous treatment such as laser, radiofrequency, glue or foam. Another may need a different approach. Sometimes, the scan shows that the visible veins are not the main problem at all.

The scan can also show whether there are deeper veins, perforator veins, superficial veins or tributaries contributing to the symptoms. That changes the treatment plan, the order of treatment, the likelihood of recurrence, and whether the visible veins should be treated directly or as part of a wider venous reflux problem.

The better question is not just, “How do we remove the veins?”

The better question is, “Where is the reflux coming from, and what treatment matches the scan?”

If you are considering treatment for varicose veins, make sure the plan is guided by a proper vascular ultrasound and interpreted in the context of your symptoms, skin changes, swelling, venous reflux pattern and overall vascular health.

Scan first. Treatment second.
