Mesenteric ischaemia and MALS treatment in Ahmedabad · Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad
Severe belly pain with a soft, calm-looking belly can mean the gut has lost its blood supply. This is an emergency. A CT angiogram should be done the same hour.
Pain after every meal, being afraid to eat, and weight loss can mean a narrowed gut artery. Other causes, including cancer, are ruled out first. Then the artery is treated.
A pressed artery behind the stomach, called MALS, is often seen on scans and usually causes nothing. An operation helps only carefully chosen people. It is not offered for a scan finding alone.
Mesenteric ischaemia means too little blood reaching the gut. It can come suddenly or slowly, from an artery or a vein. Each kind has its own first treatment.
Dr. Jivraj Mehta Hospital. Dr Harsh Shah has 18 years of experience in bowel and gut surgery. The service covers the whole range: emergency bowel assessment, work with interventional radiology on opening blocked arteries, blood-thinner plans for vein clots, nutrition support, and careful testing before any ligament operation.

| Kind | What happens | First treatment |
|---|---|---|
| A clot travels into the gut artery | Often from the heart, in people with an irregular heartbeat or a recent heart attack. | Open the artery. Through a catheter, or by an operation. |
| A clot forms on an old narrowing | The gut artery was already narrowed by hardening. Then it closes. | Open the artery with a stent, or a bypass. |
| Low flow without a blockage | A very sick patient in intensive care, on drugs that tighten blood vessels, or on dialysis. | Treat the cause. Medicine into the artery to widen it. |
| A clot in the gut vein | Linked to clotting disorders, liver disease, recent surgery, infection or birth control pills. | Blood thinners. Most people need no operation. |
| Slow narrowing (chronic) | Pain after meals for weeks or months, with weight loss. | A stent in most. Bypass for some. |
| Median arcuate ligament syndrome (MALS) | A band behind the stomach presses on one gut artery. | Careful testing first. A ligament release only for selected people. |
The broader gastro service, from a first consultation to scopes and scans, is on our gastro consultation page. This page is about one group of problems: a gut that is short of blood.
A patient in great pain whose belly feels soft and normal on examination needs a CT angiogram at once. By the time the belly becomes hard, part of the bowel may already have died.
This sign is easy to miss. The pain seems out of proportion. The doctor presses, and the belly is soft. Blood tests may look normal. It is tempting to wait. Waiting is the mistake. Bowel without blood can die within hours.
| Background | The likely kind |
|---|---|
| Irregular heartbeat, a recent heart attack, or an artificial heart valve. | A clot travelling into the gut artery. |
| Known hardening of the arteries, earlier pain after meals, weight loss. | A clot on an old narrowing. |
| Very sick in intensive care, on blood pressure drugs or dialysis. | Low flow without a blockage. |
| A clotting disorder, liver disease, recent belly surgery or infection, birth control pills. | A clot in the gut vein. |
| Older age, after heart surgery or surgery on the main artery. | Any kind. |
Go to an emergency department now if you have any of these.
A CT angiogram is the one test that decides the outcome. It is done straight away, with contrast. It is not delayed for a kidney report or a rising lactate.
A normal lactate does not rule this out. Lactate rises late, after the bowel wall has died. Waiting for it to rise before ordering the scan is the classic error in this disease. Our rule is simple. Suspect it, then scan it.
Slow narrowing of a gut artery, and MALS, are diagnoses made only after other causes are ruled out. Endoscopy and scans come before any artery test is trusted.
Weight loss and pain after meals are also signs of stomach, pancreas and bowel cancer. So cancer is ruled out before the pain is blamed on a narrowed artery or a ligament.
| Possible cause | How it is checked |
|---|---|
| Cancer of the stomach, pancreas or bowel. | Endoscopy and cross-sectional scans, before any artery treatment is planned. |
| Peptic ulcer. | Upper endoscopy. |
| Gallstones. | Ultrasound. |
| Pancreatitis, acute or long-standing. | Blood tests and scans of the pancreas. |
| Inflammatory bowel disease. | Scans and endoscopy, with a gastroenterologist. |
| A sensitive gut without a blockage. | Considered once the other tests are clear. |
A clot in the gut vein can also be the first sign of a hidden illness. So after a vein clot, a search for an underlying cause, including cancer and blood disorders, is part of the plan. This is not to alarm you. It is the step that prevents the next clot.
Treatment ranges from blood thinners alone to an emergency operation. The kind of problem, and whether the bowel is still alive, decide which step you need.
| Step | Who it is for |
|---|---|
| Support and medicines. Fluids, antibiotics, a stomach tube, pain relief and blood thinners. | Everyone with suspected acute ischaemia, started at once. |
| Blood thinners as the main treatment. | A clot in the gut vein without signs of dead bowel. |
| Treating the cause of low flow, with medicine into the artery. | Low flow without a blockage in a very sick patient. |
| Opening the artery through a catheter. Clot removal, clot-dissolving drugs, a balloon and a stent. | A blocked artery without signs of dead bowel. |
| An operation to look at the bowel, with the artery opened during it. | A blocked artery with signs that bowel is dying. |
| A planned stent or bypass. | Slow narrowing with pain after meals. |
| A ligament release operation. | Carefully selected MALS only. |
Several treatments start together the moment this is suspected, while the scan is being arranged. They are not done one after another, because time is bowel.
For a blocked gut artery without signs of dead bowel, opening it through a catheter is now the first choice where the skill is available. It is less invasive than an open operation.
| Situation | Approach |
|---|---|
| Artery blocked, belly not yet hard. | Through a catheter first. The clot is sucked out or dissolved, and the artery is stretched and stented. |
| Artery blocked, signs that bowel is dying. | An open operation to look at the bowel. The artery is opened in the same operation, by stenting or by removing the clot. |
| A travelling clot, and no catheter team available. | Open removal of the clot from the gut artery. |
| A clot on an old narrowing. | A stent, or a bypass graft from the main artery. |
The older habit was to go straight to an open operation. Current guidance has moved away from that where a catheter team is ready. But when the belly shows that bowel may be dying, the bowel must be seen. Then an operation is needed, and the artery can be opened during it.
Blood flow is restored before any bowel is removed. Bowel that looks dead often recovers once blood returns. Only bowel that is clearly dead is removed.
After the artery is opened, the bowel is checked for colour, movement and pulses in its blood vessels. A special glowing dye can help, where available. The length removed and the length left behind are measured and written down. That last number shapes the rest of your life.
When it is unclear whether some bowel will survive, the belly may be closed only temporarily. A second planned operation follows in 24 to 48 hours to look again. This is a sign of careful judgement, not of something gone wrong. The bowel is often not joined in a very sick patient. A stoma, or a join at the second look, is safer.
Sometimes the whole small bowel has died, in an older, frail patient. Then it may be kinder to close and give comfort care. This is a senior surgeon’s decision. It is discussed honestly with the family, before the operation, not after.
For a clot in the gut vein, blood thinners are the main treatment. Most people recover without an operation. Surgery is kept for signs of dead bowel or getting worse.
The blood thinner starts at once. How long it continues depends on the cause. Many people need it for life. A blood specialist helps find the cause and plan the length of treatment. In a few severe cases, a clot-dissolving drug through a catheter is used at a specialist centre. If an operation is needed, as little bowel as possible is removed, and a second look is planned.
Here the gut artery is open, but too little blood flows through it. The illness behind it is treated first. Surgery is only for bowel that has already died.
Many people with these conditions never need a belly operation. A vein clot is treated with blood thinners, a narrowed artery with a stent, and a scan finding of MALS alone needs no surgery.
| Situation | Why surgery is not the answer now |
|---|---|
| A gut vein clot without signs of dead bowel. | Blood thinners are the definitive treatment. |
| A blocked artery, belly not hard, catheter team available. | The artery is opened from inside first. |
| Low flow without a blockage, bowel still alive. | The cause is treated. Medicine is given into the artery. |
| Slow narrowing suitable for a stent. | A stent is the first choice. An open bypass is kept for unsuitable arteries. |
| A pressed artery seen on a scan, with no matching pain. | This is common and usually harmless. No operation. |
| Belly pain not yet explained by other tests. | MALS is a diagnosis of exclusion. Other causes come first. |
For long-standing pain after meals from a narrowed gut artery, a stent placed through a catheter is the first choice. Food, weight and heart risks are treated alongside.
A stent is a less invasive route. The artery may narrow again in time, more often than after a bypass. An open bypass is used when the artery is not suitable for a stent, in a fitter patient. Most people with this condition have lost weight and are poorly nourished. So nutrition is built up before and after treatment.
Choosing the right person is the whole difficulty with MALS. The pressed artery is common on scans and usually harmless. Surgery on a scan finding alone can cause harm.
The median arcuate ligament is a band of tissue near the top of the belly. In some people it presses on the coeliac artery, which feeds the stomach, liver and pancreas. Many people have this pressure on a scan and feel nothing.
| Feature | Why it matters |
|---|---|
| Upper belly pain after meals. | The typical pattern. |
| Weight loss, being afraid to eat. | The pain is changing how you eat. |
| A sound over the upper belly that changes with breathing. | It suggests real pressure on the artery. |
| Pressure that gets worse on breathing out, on a moving scan. | The ligament presses harder as the chest empties. |
| Pain relief after a trial nerve block. | A useful sign that a release may help. |
| Every other cause ruled out. | MALS is accepted only after this. |
Every MALS case is discussed by a joint team of the surgeon, the interventional radiologist and the gastroenterologist. When surgery is chosen, the ligament is divided and the nerve tissue around the artery is cleared. This is done by keyhole surgery, laparoscopic. A stent alone usually fails, because the pressure comes from outside the artery.
We say this plainly before consent. Many carefully chosen people improve, but not all. Some pain may stay or come back. This operation does not promise relief from belly pain.
For planned treatment of chronic narrowing or MALS, there is time to prepare. Nutrition, heart health and a clear understanding of what to expect come first.
After emergency treatment, the first days are spent in intensive care. A second look, feeding plans and kidney care follow a set pattern.
| When | What happens |
|---|---|
| Day of surgery | Intensive care. Fluids, blood thinner and antibiotics continue. Urine, lactate and belly pressure are watched. |
| Days one to two | The planned second look, if needed. The bowel is checked again. A join or a stoma is made, and the belly is closed when safe. |
| Days two to five | Feeding through a vein starts early if a large length was removed. The kidneys and belly pressure are watched. |
| Day five onwards | Food by mouth or tube as the bowel recovers. Stoma teaching. The remaining bowel length is written down. |
Before going home, several things must be in place. You are stable and off blood pressure drugs. Feeding is set up, with a written plan and a dietitian. The remaining bowel length is in the discharge summary. The blood thinner plan says how long and why. The cause, such as an irregular heartbeat or a clotting disorder, is being treated.
Come back at once with any of these.

These reviews are from Dr Harsh Shah’s two Google listings, quoted exactly as written. They describe his bowel and emergency care. None names this exact condition.
Acute mesenteric ischaemia is life-threatening. Many patients do not survive even with quick treatment. The risks are explained to the family in person, before theatre.
Emergency surgery for a gut without blood: bleeding, infection and blood poisoning, kidney failure that may need dialysis, heart and lung problems, and a rise in belly pressure that may need the belly left open for a few days. A leak from a bowel join. A stoma, for a while or for good, which is common. A further operation. If a long length must be removed, short bowel syndrome, which may mean feeding through a vein or tube for life. How much must be removed is known only during the operation. Death is a real possibility, and it is stated plainly to the family.
A ligament release for MALS: bleeding, including from the coeliac artery or its branches, which is uncommon but can be serious. Injury to the main artery, food pipe, stomach or pancreas. Changing to open surgery. Air around the lung. Pain that stays or returns. Rarely, a stent in the artery later. Death is rare.
Dr Harsh Shah goes through each of these in person before consent, with the figures that apply to you.
Follow-up checks the stent or bypass, feeding, weight and the blood thinner. Finding and treating the cause is the step that prevents the next event.
| When | What happens |
|---|---|
| At discharge | Bowel length left, blood thinner plan and feeding plan written down. |
| Two to six weeks | Weight, nutrition, wound and stoma review. Blood thinner checks. |
| Three months | A duplex scan or CT angiogram of the stent or bypass. Heart risk care. |
| Every six to twelve months | Artery checks and nutrition. Vitamin B12 if the end of the small bowel was removed. |
| The underlying cause | Heart rhythm treatment, heart scan, and clotting and blood disorder tests after a vein clot. |
| Short bowel | Lifelong follow-up with the gut failure team. Watch for liver, line, kidney stone and bone problems. |
| After MALS release | Symptom review at three, six and twelve months. An honest rethink if pain persists. |
The cost depends on the kind of problem and the treatment. An emergency with intensive care costs far more than a planned stent or a keyhole release.
The estimate also depends on the catheter treatment, any second look, the days in intensive care and feeding through a vein.

Yes. Lactate rises late, after the bowel wall has died. A normal lactate does not rule it out. If the pain is far worse than the belly looks, a CT angiogram is done straight away.
No. The small risk to the kidneys from contrast is far smaller than the risk of missing dead bowel. The scan is not delayed for a creatinine result.
No. Blood thinners are the main treatment, and most people recover without surgery. An operation is kept for signs of dead bowel or getting worse.
When it is unclear whether some bowel will survive, a planned second look at 24 to 48 hours lets the surgeon check again. It saves bowel. It is not a sign that something went wrong.
Not on the scan alone. This finding is common and usually harmless. MALS is accepted only when the pain fits and every other cause, including cancer, has been ruled out.
Many carefully chosen people improve, but not all. Some pain may stay or come back. This is explained honestly before consent.
The length depends on the cause of the clot. After a vein clot, many people need it for life. A blood specialist helps set the plan.
