Pinhole Surgery - A Revolution in
The word “Surgery” is scary for anyone. No
one likes their body to be cut. Surgeons the
world over are thinking in terms of minimal
invasive surgery - keyhole surgery.
Keyhole surgery was conceived by MIOT
Hospitals and wherever possible we adopt
The advantages of Keyhole Surgery are:
It causes least damage to the blood vessels,
nerves, muscles, tendons etc.
There is less bleeding and we can do away with the
blood transfusion and the complications of blood
It does not expose the vital organs to external
environment and thereby reduces the rate of
Only a few days of hospitalisation is required.
The patient can return home in the shortest
The scar no longer bothers young ladies!
fantasy to reality
Ever since keyhole surgery was pioneered, surgeons
began dreaming of reducing the size of the keyhole.
Dreaming is important in science, because fantasy
always precedes reality.
Every millimetre of our body is supplied with blood
vessels. Even microscopic cells in our body get
their nourishment from the blood, especially oxygen.
Every living organ is nourished by oxygen, otherwise
it dies. We see in every human body arteries carry
oxygenated blood from the heart, and veins carry
deoxygenated blood back to the heart.
Every part of the human body including the minute
microscopic cells can be reached or accessed through
these blood vessels. All it takes is a puncture the
size of a pinhole.
Having said this, I would like you to see how we
have reached every part of the human body through
this route and made use of it for treating many
serious illnesses which was not possible earlier.
This simple thought is going to cause a
revolution in medicine.

Pinhole Surgery can make Open Surgeries “in vein”
cutting. No pain. No bleeding. And generally, no
anesthesia. MIOT Hospitals announces a breakthrough
in options to open surgery.
Interventional radiology is a new speciality, which
treats patients using minimally invasive techniques,
usually as an alternative to traditional surgery.
This important subspecialty of radiology,
contributed to some of the most significant medical
developments. Most patients will have heard of "keyhole surgery" but interventional radiologists go
one step further and perform "pinhole surgery".
Who is an Interventional Radiologist?
Interventional radiologists are doctors trained in
radiology and experts in reading X-rays,
ultrasounds, CAT scans and other medical images.
This expertise with imaging techniques enables them
to guide small catheters and guide-wires through
blood vessels to treat many diseases. These small
catheters (tubes) are usually only a few millimetres
In fact, interventional radiology is termed “pinhole
surgery” because of the small holes that are made in
the skin to perform these procedures.
Pinhole procedures can be performed for many
These include blood vessel blocks. Blocks can occur
in blood vessels anywhere in the body: in the neck,
leading to a stroke; in the leg leading to gangrene;
in the kidney leading to renal failure and so on.
Previously reestablishing blood flow in these cases
involved surgery. Now thanks to pinhole surgery they
can be carried out with local anesthesia.
We insert a catheter through the groin vessel
(chosen because it’s the widest vessel) and using
imaging guidance navigate beyond the
obstruction and insert a stent to restore the blood
Pinhole surgery is also used to control abnormal
bleeding anywhere in the body. This is called
embolisation - performed for acute
life threatening diseases like coughing up blood,
uncontrolled bleeding in the intestines, during
The conventional treatment for these was blood
transfusions. Now, with pinhole surgery, we identify
the site of the blood, use the catheter to access
the blood vessel and block it with chemical agents.
Using the same technique we can block the blood
supply to tumours thereby ‘starving’ them .
Similarly, liver tumours can be “cooked” using radio frequency waves or chemo - therapy can be
administered directly to them.
Advantages of Interventional Radiology
Only a short hospital stay is required for most
General anaesthesia is usually not required.
Risk, pain and recovery time are reduced compared
to conventional surgery.
Pinhole surgery is available for many diseases, but
few patients know to ask about them, or to seek a
second opinion from an interventional radiologist.
Usually patients do not have direct contact with
interventional radiologists. General practitioners
still refer their patients to surgeons
and rely on the surgeon to provide advice on
available treatment options.
Surgeons may or may not know the minimally invasive
treatments that another specialty offers. Eventually
this situation will change and
patients will be sent to the least invasive
practitioner for consult first, but in the meantime,
it is important for you to know that you may have a
