Interventional radiology is a specialty in which minimally invasive procedures are performed through a pinhole access. The procedures are performed with imaging guidance (X-ray,ultrasound or CT) to treat problems in various parts of the body.
Through a pinhole access into the blood vessel in the groin the interventionalist can reach the blood vessel of any organ in the body to detect and treat the problem.
Many interventional procedures have replaced open surgical procedures with the added advantage of higher safety and faster recovery.
For example, for varicose vein of the legs, laser or RF ablation has been proven to be safer and equally effective as open surgical ligation/ stripping of the veins with much less pain and faster recovery.

Best Interventional radiologist treatment in chennai and Dr.Karthikeyan Damodharan is one of the best Interventional radiologist Doctor in chennai, India.


No Stitches


Fewer Complications


Less Pain


Shorter Recovery Time



Arteries transmit oxygen-rich plasma from the heart, feeding every part of the body. The one exclusion is the pulmonary artery, which carries oxygen-poor plasma from your heart to your lungs, where it exchanges carbon dioxide for oxygen.



Veins transmit the blood back to the heart wherever it is refilled with oxygen. The afresh oxygen-rich blood gets pushed back into the heart via the pulmonary vein.





Capillaries bond the arteries to the veins. Vascular illness usually happens at sites of unbalanced blood flow. For example, when the blood movement in the arteries deviations direction suddenly.

Treatment of varicose veins

I had been suffering from chronic venous insufficiency for a long time. As an interventional cardiologist, I have to stand for long hours with a heavy lead apron in the cath lab. My legs would feel heavy and get really uncomfortable at night. After having done Glue ablation with Dr Karthikeyan, I haven’t taken a single painkiller. My legs no longer ache after a long day work. Can’t thank Dr Karthikeyan enough for being so caring. I will definitely recommend Dr Karthikeyan for the successful treatment of varicose veins.

Uterine Artery embolization procedure

Dear Dr. Karthikeyan, I hope this message finds you well. I wanted to express my deepest gratitude for the exceptional care and expertise you provided during my uterine artery embolization procedure at Miot International Hospital. Having traveled all the way from Fiji, seeking a solution to alleviate the challenges posed by my fibroids, I was fortunate to find you as my doctor. Your confidence and assurance during our consultation instilled in me a sense of hope and trust in the uterine artery embolization procedure. Post the procedure, the results were nothing short of miraculous. Within two days, I felt a remarkable difference - my back pain had disappeared, and I experienced a newfound lightness. The efficiency with which I could carry out my daily tasks increased significantly, and the persistent fatigue I once battled was a thing of the past. I am truly grateful for the life-changing impact this procedure has had on me. Your skill, compassion, and dedication have not only cured my fibroids but have given me a renewed sense of life and well-being. In my eyes, you are nothing short of a miracle worker, a true blessing, and I consider you to be a Godsend. Thank you once again, Dr. Karthikeyan, for the amazing work you have done. Your commitment to your patients' well-being is truly commendable, and I am forever grateful for the positive transformation you have brought into my life. Dipti Sharma Fiji 🇫🇯

I highly recommend this RFA procedure to those who are suffering from varicose related problems

I was diagnosed with Varicose and Dr. Karthikeyan Damodharan briefed me to undergo RFA (Radio frequency ablation) procedure,which is a new technology to treat varicose problems. Since, the technology is not known to many. I had my doubts, but Dr. Karthikeyan Damodharan and Dr. Avinash walked me through the process and I underwent a painless RFA procedure. My thoughts of a painful post-op days were wrong. I didn't feel any pain and went back to my daily routine in 2 days time. I highly recommend this RFA procedure to those who are suffering from varicose related problems.

Subsequently, thrombolysis, angioplasty and stenting

My husband is pro-thrombotic, in addition, he has been battling other complications, MIOT has been our choice of hospital since 2014. Just ahead of his periodic review this month, he had spontaneously developed discomfort, crippling pain while walking and discoloration of the right leg big toe and foot. This was duly reported during the routine review and hence was referred for further evaluation and review by Dr Karthikeyan Damodharan, Director - Vascular and Interventional Radiology. Dr Karthikeyan Damodharan examined and investigated the condition and after taking time to go over the diagnosis and my husband's existing health complications and our concerns, clearly explained the underlying condition, treatment options, the urgency of the hour & complications that can arise due to delay and the best available choice in a manner which put us both at ease and made us confident as the entire interaction was filled with both personal touch and care for the patient while ensuring we were better informed to make the right decision.

The treatment that I received from Dr. Karthikeyan Dhamodharan was excellent. He is so friendly and ensure that I am properly informed about my health and care. Dr. Karthikeyan Dhamodharan did a great job with my first ever surgery i;e Angioplasty. He explained everything to me in a very clear manner and now my health is very fine. Dr. Karthikeyan Dhamodharan took great care of my health. He really took his time to explain my conditions with me as well as my treatment options. He relates well to people and listens to our concerns and takes appropriate action on the symptoms. He always takes the time to explain things to me in terms that I can understand well.

A big thank you

Under the overall supervision and guidance of Dr. Karthikeyan and alongwith Dr. Avinash, I underwent an AV Fistula angioplasty on October 9th, 2021. Initially sceptical of the outcome of this procedure, as I have been having complications with dialysis using the AV Fistula, my treatment had to have alternatives if this Angioplasty failed for any reason which I could not immediately perceive. The procedure went very smoothly save mild discomfort lasting about an hour. I was able to see from beginning to the end the origin of the problem requiring the procedure, and the entire procedure itself wherein the angioplasty cleared the blocks from the upper arm enabling the use of the fistula for dialysis. Both doctors attending on me showed expertise in their field of vascular surgery, and for me personally a new lease of life. I would unhesitatingly recommend others having blocked blood vessels to contact Dr. Karthikeyan Damodaran and Dr. Avinash at MIOT International Hospitals in Chennai. A big thank you to both doctors and their team for an efficient and effective procedure to clear blocks in the blood vessel and render an otherwise defunct fistula active again. Jayant Krishnaswami

My Father had Covid infection with Jejunal (small bowel bleeding) Diverticular bleeding. He has identified the bleeding vessel precisely in CT Abdominal Angiogram and suggested interventional management for it in Cathlab. Within no time he made the Cathlab ready and shifted him to it. Sir has successfully done coil embolisation of the active bleeding artery in Cathlab under local anesthesia and arrested the bleeding... He saved the life of my father even in this COVID pandemic and my father is discharged from hospital and doing good now. Thank you sir for your timely and precise expert interventional management...

Multiple Fibroids Treatment

I was diagnosed with Multiple Fibroids, Endometriosis cyst and Adenomyosis, a few years back and suffered from excessive bleeding, exhaustion, pain, anemia and bloating. Doctors I consulted suggested a Hysterectomy. I wanted to avoid undergoing a surgery, that when I heard about Fibroid Uterine Artery Embolization, I was a little skeptical but decided to get it done after the Doctor explained about the procedure.I had pain for 10-15 hours post-procedure, I was given adequate pain killers and was well taken care. I was on my feet within 24 hours, I had tiredness and mild discomfort for 3-4 days. I was almost back to normal after a week. Dr.Karthikeyan Damodharan , Dr.Malla Avinash and their team were easy to reach (before, during and after the procedure). There was improvement in my first cycle itself. Its 4 months since the procedure, now my periods are normal and there is no pain, I am a healthy person now and my hemoglobin level is almost normal. I am very happy with the outcome.
