To all patients requiring neurological treatment,

I would like to share my experience with all patients who have neurological problems.

I am 50 years old and was suffering from severe headache since two and a half years 24x7. it had made my life miserable. I consulted many neurologists , popped in all kinds of medicines for migraine, vertigo, depression, spondylosis etc. six months back an MRI revealed that i have a congenital problem called "Chiari1 malformation" and that surgery is the only cure. I was very scared about it being fatal. I did a lot of research online to understand my problem, took couple of neuro surgeon opinions.

I was advised to consult Dr. Abhaya Kumar in this hospital. He is extremely intelligent, confident ,informative , ready to answer
all my queries and he is very patient and gentle in treating patients. He was with me at every step- pre anasthesia., soon after surgery in the recovery room and back in the ward. At every step he informed me very well as to what is going to happen next and why . it was a very satisfying experience for me as there was no room for fear left. My surgery went off very well. Their was minimum , tolerable pain of the surgery but all the agony of two and a half years was all gone in a jiffy. Post operative care is also very good.

I would recommend Dr. Abhaya Kumar strongly to anyone with neurological problems.

Thank you doctor for giving me a new life to enjoy with my family and friends. YOU ARE THE BEST DOCTOR IN THE WORLD

To all patients requiring Minimal Invasive Lumbas Fusion Surgery.

I Mrs. Armaity M. Bajan am a 62 year old lady. From December 2010 I was suffering from lower back and leg pain. I could not sit for long, sit or even sleep peacefully as the pain was too severe. My family doctor told me it could be an age related pronlem and asked me to consult an orthopedic, who asked me to get an x-ray done and then an MRI of lumbay spine. But there was no improvement with his treatment. I also tried many other medicines (allopathy, homeopathy, aurvedic etc) but found no results. The pain kept increasing & spreading gradually. I started feeling very weakand tired at the end of the day. My cousin who is also a doctor advised me to consult a Neuro Surgeon - Spine Surgeon. I the consulted Dr. Abhaya Kumar from this hospital. He heard my case & saw my MRI report. He told me that I had two problems, the pain in my upper back is due to Rheumatism & the lower back pain is due to grade 1 anterolisthesis of L5 over S1, diffuse disc bulge with annular tear. He advised me to see Dr.Sunil Kumar Singh - consultant rheumatology and get the upper back pain in control. Within 3 months of treatment my rheumatic pain was in control & I once again visted Dr. Abhaya Kumar who explained me about the surgery of Minimal Invasive Lumbas Fusion.
I was operated on 19th June 2012 and when I was out of anaesthesia I reliased that my pains had vanished. The next day I walked with the help of a physiotherapist without any pain. I was adivised not to sit except whie using a washroom or bathing & could walk wearing a belt but without any pain. Gradually my sitting period increased & slowly after six months of being operated I free of all pains & the belt. I am just advised not to bend & lift heavy things, otherwise my life is normal.
I am extremely thankful to Dr. Abhaya Kumar, his team & the extremely co-operative staff of Kokilaben Dhirubhai Ambani Hospital who helped me get well within a few days. A great thanks to Dr. Sunil Kumar Singh & also to Mr. Vishal - from the physical Medicine & Rehabilitation department to help me out with my exercises.

On October 23rd this year, it will be one year since you performed my back surgery. During the 10 years prior to that there had been about 3-4 episodes triggered by a bending forward action that resulted in extreme pain but I seemed to recover after 2-3 days of rest. It was after the final episode that occurred about 2 years prior to the surgery that seemed to cause lingering pain even after 2 weeks of rest. Over the next two years, the pain only kept on increasing until it reached a stage where a distinct limp crept into my walk. I have quite hectic lifestyle with long hours of sitting on planes as well as sitting for long hours at my desk in office.

Prior to the last episode I would go to the gym about 5 times a week and had also run 3 half marathons. However the pain had kind of crippled me and I actually had to give up on both the gym as well as my running.

I was finally referred to you by Dr. Mohit Bhatt who is a personal friend of some one I know very well. It was Dr. Bhatt who suggested that I explore the possibility of undergoing minimal invasive lumbar dissectomy. I truly think that this advise was really a blessing. Soon after I met with you, I decided on undergoing the surgery in the hope of resolving this problem. I had not even dreamt prior to this that I would be on my feet on the same evening of the day the surgery was performed and more importantly walking without a limp. Today all my activities have returned to normal and I continue to do the stretching exercises recommended by you. I am able to take my dog out on long walks on the beach and am hopeful of running in the next Mumbai marathon in January next year.

At this point in time there are some rare instances when I feel my back is stiff and I feel a little pain as well as a tingling sensation in my left moot. I am writing to you to thank you for improving my life and brining it back to almost normal.


Trust all is well with you and though late, please accept my wishes for a very Happy New Year.

As discussed with you earlier, I participated in the Half Marathon ( 21Kms ) last Sunday at the Mumbai Marathon and completed the entire run without any issues. In fact it is a matter of great happiness to me that I could better my previous personal best timing and clocked the 21kms in 2 hours and 31 minutes.

I personally owe you and big “ Thank You “ for advising me on the course of treatment for my spine and then for the successful surgery. A couple of years ago I had almost resigned to the fact that I may never been able to run again. Those were the times when I could not even walk straight. I am aware that there are not many people who dare to run long distance after a spine surgery and it is only because of your advice and more importantly encouragement that I could run again and then go on to complete this feat.

The last 5 months of training leading to a situation where I was running about 10-12 kms three times a week and then completing the half marathon has been a great boost to my confidence. I shall remain indebted to you for the rest of my life.

Dr. (Mrs.) Chandra P. Kaul

I am a Gynaecologist from Lokhandwala Complex, Andheri (W) and now staying at Karjat for the last 5 years.

I would like to pen down a few comments on my experience of undergoing Spinal Surgery by Dr. Abhaya Kumar at your hospital on October 22, 2013.

I was diagnosed with Lumbar Canal Stenosis and was operated for Transforaminal Inter-disc fusion by Dr. Abhaya Kumar.

I found Dr. Kumar as very precise in diagnosis and empathetic in explaining the relative merits of the options available between the physiotherapy and the surgery. It gave us the confidence for undergoing surgery performed by him.

The minimalist surgery gave me a dramatic recovery and fast healing.

During and after the surgery, I found Dr. Kumar very communicative and ready to respond to any queries by me.

We wish him well and congratulate the K. Ambani Hospital for having an illustrious professional like Dr. Abhaya Kumar to enhance the reputation of the hospital. The large number of people suffer the ailment of backache. The hospital can create awareness among the population to remove the unfounded fears and myths about the spinal surgery.

My husband, Dr. Om Kaul, who is an Internationally reputed Management Consultant and a doctorate from U S A has become a fan of Dr. Abhaya Kumar.

Dear Madam

I would like to thank you and the excellent team of doctors and entire support structure which exists in your hospital

I am a 42 year old corporate executiv , and had visited your hospital on 4thJan 2014 with a minor problem of pain in the right shoulder and a suspected case of spondylitis. However post MRI this turned out to be a tumour in the spinal cord (Scwannoma in C5/C6) and referred to Dr Abhaya Kumar which was slowly impairing the use of my right hand.

For me it was a bolt from the blue , however the way me and my wife were counselled by Dr Abhaya Kumar is was truly extraordinary, he not only gave ample time but was patient with all my query (I had plenty of them)

The operation was done using minimally invasive surgery and I was discharged within 5 days – recovery was faster than what I had anticipated. During this short period the behaviour of the entire staff was exemplary, specially the nurses were very helpful and cooperative.

Today, after 3 months of the operation, I have recovered fully, and have resumed normal live. Tumor is gone completely . When I compare my self with the experiences I have heard about similar patients, I feel truly blessed.

Thank you Dr Abhaya Kumar, and a big thumbs up to the entire team of KDAH. You Guys truly Rock !!!

With Warm Regards

This is to show my gratitude to KDAH and Dr Abhay Kumar Neurosurgeon in particular for the difference he made in bringing happiness to my wife Rita Chaturvedi and my family.

It's just a year back, same time, when My wife Rita was having problems in comprhension and we went to Dr Dean Creado , who suggested a Brain scan , and she was diagnosed with a brain tumour (meningioma). She was admitted on 11th jan 2014(KH1000229403) under Dr Abhay Kumar. As soon as we met him, we were so impressed by his forthringht approach and trusting manner that we were blessed to be in his care. He has GODOTIC arms and fingers(KDH boasts of Robotic machines!), with such expertise, he makes most difficult surgeries look so comforting and easy! with minimum non invasive interventions, he removed the offending meningioma and by 17th Rita was discharged ! She remained on his advises and till now, she is absolutely back to her normal alert cheerful ways !

We bless Dr Abhay and his team of nurses from heart and shall remain indebted to him for life !

God Bless,

Respected doctor,

This article is about Nishit Desai's epilepsy history from the start of the problem till the surgery done before 3 months.

My brother got his first epilepsy attack when he was 6 years old, he was accompanied by my mother in an auto rickshaw, wherein he fainted and mom was completely unaware of what was happening, still she gathered the guts to go to a local doctor and give him sedation as another attack shouldn't follow till she reaches a big hospital where he can get treated in the right manner.

Soon medication began but as we were taking homeopathic medicines, my mom though of showing him to a homeopathic doctor as she was unaware about the intensity of this problem. She thought that It must be like any other small illness which could be cured through this particular treatment as well. So for 2 years she was supposed to give tagretol to Nishit, as per guided by the doctor whom she consulted initially, But she chose to give him homeopathic medicine and deprived him of tagretol. This resulted in a disaster at the end of 2 years as he got his second big attack and was rushed to the proper neurologist. He told us that mom made a big mistake by opting for homeopath as epilepsy cannot be stopped or cured so easily.

Soon she started with the right treatment guided by the best neurologist in the town before 15 years. But now we understood that the problem Nishit had was very grave and that the smaller attacks were very frequent, say either twice or thrice in a month or else every fortnight. We visited all possible neurologists in the town and to stop the attacks, medicine dosage was increased very frequently.

But the side effect of all this started to show in a major way. Nishit, who once was the most active kid we had ever known, started showing signs of dullness, loss of perfection in many areas, was not able to study with concentration and many more. Now this was a worrisome factor so we decided to get a solution. But everywhere there was only one suggestion, that he should get operated. My mom and I used to get cold feet even thinking about a surgery.

As he grew older, according to his weight and age, medicines kept on increasing, till a limit where he used to consume 3000mg per day. My brother who used to climb up trees 8 his childhood and was known for how quick he was, could not even get up quickly to get himself a glass of water. Everyday we used to think what should be done until once mom decided to get the MRI done and show it to Dr.Jayanti Mani.

Her name was suggested to us by another neurologist whom we used to consult. It turned out to be a blessing in disguise ,as when she got his Video EEG, Pet Scan, Spect Scan and MRI done, she told us that all this could be reduced or even stopped if we get Nishit operated. All the results were showing a solution but it was very difficult for us to take this decision . Seeing my brother suffer every single day with attacks so frequent and unable to be active, we did give a serious thought. Though we were scared, Dr. Jayanti Mani gave us the confidence that there was nothing to get worried about and that we should meet the neurosurgeon.

Finally we met Dr.Abhay Kumar , he guided us and told us the pros and cons about the surgery. There were chances that Nishit would get paralyzed, but that would be temporary and was solvable with physiotherapy. The other possible problem would be a major blood loss, but that could also be solved by giving him blood extrenally. So whatever the consequences, there was some or the other solution except an extreme situation. But we had to take a chance as Nishit was in a way dying everyday due to medicines and attacks. So we took a decision and just confided in both our doctors and proceeded on with the surgery plan.

Nishit got operated on the 14th of October 2014. When he was in the operation theatre , there was only prayers we could rely on. After around 10 hours of the whole procedure nishit was shifted in the ICU, and the doctors said he was absolutely fine. We heaved a sigh of relief. I could see the happiness in my mother's eyes. For 17 long years, everyday and every night, she used to only think of nishit's medicines and whether he is fine or about to get an attack. I was longing to see a satisfied face and there it was. All thanks to Dr.Abhay Kumar and Dr.Jayanti Mani.

Surgery had its own set of pain and uneasiness, but comparitively, it was easier for Nishit to recover as he was taken care of and we were relieved that we were in safe hands. Today it's been more than 3 months, he is absolutely fine, no attacks, and gradually medicines will also decrease.

It is nothing short of a second birth after his surgery and it was due to 2 great doctors. They are next to God for us as if this would not have happened, a nishit could have never lived his life to the fullest. Thanking you is an understatement.

Dr. Abhaya Kumar | Neurosurgery

A 87 year old women suffering from left Trigeminal Neuralgia for last 10 years was admitted with us recently.

She had tried conservative treatment with medicines.

She had relief with medicines for 8 yrs, but since last 2 yrs the medicines were not giving her relief of pain.

She was seen by Dr Abhaya Kumar, Consultant Neurosurgeon at KDAH.

Gold standard surgical treatment for Trigeminal Neuralgia is Microvascular decompression of trigeminal nerve.

Since this patient was elderly and not fit for open surgical treatment we decided to do percutaneous balloon compression of trigeminal nerve after discussion with the patient and her relative.

This procedure was done successfully and patient had excellent relief of pain.

Balloon compression treatment for Trigeminal neuralgia is a simple day case procedure done under local anesthesia or mild sedation. Success rate is around 90% with this procedure.

For more information on Trigeminal Neuralgia and different treatments available at KDAH, please refer patient's guide.

All Treatment modalities are available at KDAH.
