Peripheral angiography is an investigation that employs X-rays and a contrast substance to aid the doctor in diagnosing a blocked or narrow artery. This test is performed on the arteries supplying blood to the peripheral parts of the body, such as the feet, legs, hands, or arms.
Peripheral angiography helps your doctor to decide if a surgical procedure like a peripheral angioplasty is required to open up the blocked arteries. During peripheral angioplasty, a balloon catheter is employed to dilate the blocked artery from inside, followed by the placement of a small wire mesh tube known as a stent inside it to keep it open and prevent further blockage. Another surgical procedure that can be performed in such cases is a bypass surgery that reroutes blood around the blocked arteries.
A specialised doctor carries out this investigation with a team of support staff such as technicians and nurses in an outpatient clinic or a hospital.
An IV line is placed into a vein of the arm before the test so that medicine and fluids can be given through it. The per-operative area is shaved and cleaned, and local anaesthesia is given. After this, the doctor makes a needle puncture through the skin into the artery and introduces a long and thin tube known as a catheter. Due to the effect of the anaesthesia, you won’t feel any pain.
A small amount of dye will be injected into the catheter, making the blocked area of the arteries appear distinctly on the X-rays. You may be hot or flushed for a few seconds after the dye is injected.

Angioplasty is a surgical intervention performed to open up blocked arteries by using a balloon and a catheter. After angioplasty, stenting is usually done, during which the surgeon inserts a small metal device in the artery. This stent makes sure the arteries remain open, and the blood flow is uninterrupted. Apart from these methods, the surgeon may sometimes perform a procedure called atherectomy, during which a device is used to remove the plaque.
The peripheral angioplasty procedure opens up any narrowed artery in your extremities, such as arms, legs, fingers, or feet. It may prevent the need to undergo more invasive procedures like bypass surgery.
You may be recommended angioplasty and stenting if you have been diagnosed with peripheral artery disease, which can result in:
The vascular surgeon performs a complete physical examination before the angioplasty and stenting procedure. Apart from this, he will run some imaging tests, such as a CT scan or an ultrasound, to locate the site of the blockage and determine its severity.
During the procedure, the surgeon inserts a small needle in a blood vessel of the upper arm or the groin area. Then a soft guidewire is threaded via the needed and advanced to the right location while observing it with a live X-ray. A contrast dye is injected through the needle that helps in locating the arterial blockages.
When the site of blockage in the arteries is clearly visible due to the contrast, a small device that appears like a small balloon is inserted in the artery, which is then inflated. The plaque is compressed outward on the artery wall to dilate it, allowing for an enhanced blood flow. After this, a stent made of metal is inserted into the artery that acts as a permanent metal scaffold to keep the artery dilated.
You might be allowed to go home on the same day or advised to stay in the hospital for a day or so for observation, depending on your condition and overall health.

A stent is a small and narrow tube that is placed inside a blocked artery or a vein to keep it open and ensure an uninterrupted blood supply. The procedure by which a stent is placed into the artery is called stenting.
These days stenting is performed in almost all angioplasty procedures. After the stent has been kept in place, the surrounding tissue starts to coat it with a skin layer. Within 3-12 months, the stent is completely covered with tissue. You may be required to take some medications to decrease the adherence of the platelets and prevent the formation of blood clots inside the stent.
Stents can be of different types, most of which are made up of plastic mesh-like material or metal. Stent grafts, however, are made up of fabric. They are employed for dilating larger arteries. Sometimes a stent can be coated with a medicine (drug-eluting stent) to help prevent further re-closing of the arteries. It is permanently left in the artery like coronary artery stents. The medicine coated on the stent prevents the overgrowth of tissue within it, thereby preventing the blood vessel from getting blocked again. The stents that lack this coating of medicine are called bare metal stents. There is a higher risk of stenosis with such stents, but medications to prevent platelet adherence are not required here. Bare metal stents are preferred in patients in whom the risk of bleeding is higher.
A coronary artery stent is a tiny, self-expanding tube made up of metal or a mesh. It is introduced into the coronary artery after balloon angioplasty. Its function is to prevent the artery from getting blocked again.
Because stents can become blocked, it's important to talk with your healthcare team about what you need to do if you have chest pain after stent placement. If there is a formation of scar tissue inside the stent, a repeat procedure may be required.
If plaque (fatty tissue) builds up inside an artery, the blood flow to the heart will reduce. This condition is known as coronary artery disease and is characterised by chest pain. The plaque can also cause a blockage in an artery supplying blood to the heart, resulting in a heart attack. Stenting keeps such arteries open and lowers the risk of such complications.

Thrombolysis is a radiological intervention that involves dissolving dangerous clots in the blood vessels to enhance the flow of blood through them and prevent long-term damage to the tissues and muscles. During thrombolysis, clot-busting medications are inserted at the site of blockage in the artery through an intravenous line or a long catheter. Sometimes, the catheter may be equipped with a mechanical device at one end that breaks up the clot physically and removes it.
Thrombolysis is generally used as an emergency intervention to dissolve blood clots in the arteries supplying vital organs like the heart, brain, and lungs. These blood clots are the main cause of ischaemic strokes and heart attacks.
Thrombolysis is also performed to remove blood clots in:
Deep Vein Thrombosis (DVT) occurs in veins of the pelvic area, legs, and upper extremities. If this condition is left untreated, pieces of the clot can get free and travel to a pulmonary artery, causing a grave condition called acute pulmonary embolism.
If a blood clot is suspected to be life-threatening, initiating thrombolysis as soon as possible (ideally within 1-2 hours) after the symptoms of a stroke, heart attack, or pulmonary embolism are noticed can be a life-saving intervention.
The interventional radiologists at Kokilaben Dhirubhai Ambani Hospital use thrombolysis to treat blood clots arising as a result of a number of conditions such as atherosclerosis, deep vein thrombosis, coronary artery disease, pulmonary embolism, heart attack, or a stroke. Our interventional radiologists, vascular surgeons, and cardiologists have the training and experience required to aptly identify the cause of the blood clotting and treat such conditions effectively.

Percutaneous transhepatic biliary drainage (PTBD) is an interventional procedure involving the introduction of a drain into the bile ducts by inserting needles via the skin. This procedure is used for the treatment of cholestasis, which may occur due to blockage in a bile duct.
Biliary drainage is often associated with stenting, especially if the blockage is cancerous, to ensure that the bile duct stays open. A stent is introduced into the bile duct, which keeps it open and prevents it from closing.
Biliary stone extraction is performed by accessing the bile tree percutaneously. A tiny basket or grasping device may be used in the process. The stones of small and medium sizes are pushed into the first part of the small intestine with the help of a tiny balloon. Larger stones greater than 5 mm are removed after the entrance of the small intestine is dilated using a tiny balloon.
Bile duct puncture is usually done under sedation and local anaesthesia. However, depending on the age and underlying conditions of the patient, in some cases, the procedure may be performed under general anaesthesia.
To prevent infections, antibiotics are administered beforehand. The procedure is performed in a sterile room with the patient lying on his back. The interventional radiologist performs the procedure under imaging guidance (X-ray/ultrasound and fluoroscopy) to confirm the direction of the puncture. He then passes a small needle into the left or the right lobe of the liver via the skin. After withdrawing the needle, the interventional radiologist gently injects a diluted contrast material to make the area more distinctly visible under imaging. Then a guide wire is inserted into the bile duct, followed by the insertion of a catheter. The catheter and the guidewire are used in combination to navigate past the blockage and reach the intestine.
After the catheter is removed, the interventional radiologist dilates the blocked liver tract to place the drainage catheter. This catheter has multiple holes used to drain the bile in two directions, inwards towards the intestine and outwards into a bag. The bag is attached to the skin and left there for a few days till the decompression of the biliary tract occurs. The catheter is flushed multiple times a day with sodium chloride during the period when the bag is attached to keep the side holes open.
If a patient is not fit for undergoing endoscopic procedures, PTBD is a better alternative. It can be performed to achieve decompression of the biliary ducts if they have been blocked by a stone or a mass lesion. It can also be used to bridge a hole if bile leakage occurs.

Embolisation is a radiological intervention that involves blocking or occluding blood vessels supplying blood to tumours. This technique is used to deal with tumours that are challenging to operate on. The interventional radiologist introduces a catheter through a small groin incision to the tumour using imaging guidance. Through this catheter, a contrast dye is injected to make the blood vessels and tumours clearly visible. Then the artery supplying blood to the tumour is blocked using synthetic substances called embolic agents. After this, the tumour grows or shrinks more slowly so that it can be successfully with surgery or chemotherapy.
Sometimes chemotherapy or radiation is targeted at the tumour directly during the embolisation procedure with minimal side effects. This process is called radioembolization and involves the injection of a radioactive substance to treat both primary and secondary tumours. When chemotherapy is given during embolisation, the process is called chemoembolization. During this procedure, chemotherapy-laden particles are directly injected into the tumour so that the target area can be treated with high doses of chemotherapy, and the exposure to the rest of the body will be minimal. The chemotherapy or radiotherapy drugs are kept by the embolic agents in the tumour so that they can’t travel to other body parts.
During the embolisation procedure, a catheter is inserted at a point in the groin area so that the femoral artery can be reached. While using fluoroscopy to guide the catheter, it is steered through the arterial system to the tumour. Eventually, the cancer treatment is delivered to the tumour directly through the catheter.
After the treatment, the patient needs to stay in the hospital for a few days. The normal activities can resume by the patient soon after discharge with some precautions.
Trans arterial radio embolisation of tumours is an interventional procedure that is used in patients in whom the tumour is not removable by surgical procedures. It is usually performed in patients with adequate liver function and a tumour too large (> 5 cm across) to be treated with ablation. Due to embolisation, there may be a reduction in the blood supply to the normal liver tissue, so the patients whose liver has been affected by diseases like cirrhosis or hepatitis are not fit for undergoing this procedure.
During the procedure, a thin, flexible tube called a catheter is introduced into an artery of the inner thigh via a small incision and passed into the hepatic artery of the liver. Then a contrast dye is injected into the bloodstream so that the doctor can visualise the patch of the catheter easily. Once the catheter is fixed, small particles are inserted into the artery to block it. This blocks the supply of oxygen and other important nutrients to the tumour, causing it to die.
This is usually the first type of embolisation procedure done for large liver cancers that are inoperable or cannot be treated with ablation. A combination of embolisation with chemotherapy is used. This is commonly performed by introducing chemotherapeutic drugs directly into the artery via the catheter, then blocking the artery at a point to ensure that the chemo drugs stay closer to the tumour and away from the normal tissues.
This procedure combines radiation therapy and embolisation. Small beads called microspheres containing a radioactive isotope are injected into the hepatic artery. After they are infused, the beads lodge in the arteries surrounding the tumour and give off radiations in small amounts to the site of the tumour for a few days. As the radiation travels a very short distance, its effects are mainly limited to the tumour.
