WHAT IS CRYOBIOPSY ?
Transbronchial cryobiopsy/cryobiopsy refers to the use of a cryoprobe to rapidly freeze samples of
peripheral lung tissue.
Cryobiopsy specimens are larger than those
obtained using traditional forceps (usually >5mm)
Initial use of this technique has focused on the
diagnosis of diffuse parenchymal lung diseases
(DPLDs)

disease: a state of the art review of procedural techniques, current evidence, and future challenges.2017

CRYOBIOPSY SAFETY CONSIDERATION
The principle risks of cryobiopsy : airway hemorrhage and pneumothorax
Pneumothorax results from a biopsy obtained
so distally that the visceral pleura is violated
Major hemorrhage is thought to be greater in
the more proximal region, where vessels have
branched less extensively and are larger but
still too distal to be protected by the
cartilaginous rings

THE JOULE – THOMSON PRINCIPLE
The decrease in temperature that is observed during the
expansion of gas from a high pressure to a low-pressure
environment.
N2O/CO2 gas, which is stored at room temperature under high
pressure,
When N2O is released at the tip of the cryoprobe, the
temperature falls to –890C within several seconds.

CRYOPROBES
Cryoprobes have been used since the late 1960s.
In the early 2000s, flexible
cryoprobes allowed for the
development of
cryoadhesion or
cryorecanalization

TRANSBRONCHIAL CRYOBIOPSY TECHNIQUE
The cryoprobe is advanced through the working channel into the peripheral lung surrounding
parenchyma to rapidly freeze and adhere to the
cryoprobe tip
It rapidly expands and cools to a temperature of –79°C
(using carbon dioxide) or –89°C (using nitrous oxide)
within 3-5 seconds

TRANSBRONCHIAL CRYOBIOPSY TECHNIQUE
The bronchoscope and cryoprobe with attached frozen
biopsy are then removed from
the airway because the
cryobiopsy is larger than the
working channel.
Resulting biopsies : 7–10 mm in greatest dimension (larger than
traditional forceps biopsies, and
lack crush artifact)

CRYOTHERAPY
Freeze – thaw cycles using extreme cold to destroy tissue
and tumor.
Physical effect is immediate, and results from the freezing
and recrystal lization of cellular water on thawing, as well
as cellular dehydration.
Vascular effects result in tissue ischemia from
vasoconstriction, platelet aggregation, and increased
blood viscosity.
Produces beneficial effects on the immune system.
Maiwand et.al - Induce proliferation of a natural killer
cells.
Increase in lymphocyte activation in the peripheral
circulation .

As the size of the probe tip is
proportional to tissue injury, many
authors recommend rigid
bronchoscopy.
Flexible bronchoscopy is certainly more accessible to the majority,
and good results can also be
obtained with the flexible
cryoprobe.
Flexible bronchoscope, it is crucial
to have the probe protrude several
millimeters from the distal tip of the
scope, so as not to freeze the video
chip.

Remove foreign bodies and blood clots in the airways.
As freezing and recrystallization depend on cellular water
content, cartilage and fibrous tissue are relatively cryoresistant.
The incidence of airway perforation is therefore markedly
reduced.
Bleeding tends to be less common because of the hemostatic
effects.
No risk of airway fires, electrical accidents, or radiation exposure.
