马里兰大学介入放射科医生向您介绍纳米刀的好处，以及操作过程

ari is one of the more exciting new tools that we have four targeted

tissue the bleach bleach it means that your

destroying something in a spot there a couple of ways and we can treat cancer

one of them as we release particles through the blood stream they'd go out

to the cancer indeed that entire area with tumor killing drugs and also once

it's shut off the oxygen to the tumor

and that's good if you've got a treaty field

but there are times

uh... we're gonna treat one spot like cleaning a spot on the carpet

means that we have to either sheet or freeze or inject things into that

now what ari is irreversible

electro pro rationing

is actually using certain very specific types of electricity through tiny

needles to actually destroyed cancer in tissue in that area

so another way to think about it

you've got an area that you want to get rid of

spot on the carpet you can put a fence around it

and then everything inside that fence

is destroyed by virtue of that electrical field that is specifically

created once the patience to sleep and we have the area cleaned off we do a

c_t_ scan to choose

are exact entry an exit points so that we know where we're going in

uh... with two the pros

once we've once we've done that we sit and we do a calculation to determine how

many probes were actually going to have to place them where they're going to be

then under c_t_ guidance we answer

uh... these needles usually somewhere between to ten

needles

again depending on the size and location of the tumor

replace the needles and confirm the location again usually with c_t_

we will

do the inflation teacher which essentially is people

these probes

opt regenerator which introduces the electrical current

into the patient and zaps the tour

once the tumors zack opt and the probes are withdrawn

oftentimes will do one final city just to make sure that there was no

unexpected

leading from the procedure

and then the patient is uh... will come out

and then they go to repair the pack you full recovery which is just a post uh...

anesthesia child care unit

and usually within four hours to patients up walking around eating

uh... we watch these patients overnight and send them home the next day

so the procedure itself uh... oftentimes will be between two and four hours of

anesthesia

because it takes a long time to get the probes and place

uh... ninety and it's a smothered small tumor to be close to two hours

there's a big too much to be close to four hours for for patients who are

considering

uh... irene

i think the most important thing

too

search out as a position with experience

and that experience should be both in iri as well as in

you know other minimally invasive procedures

uh... so that they can be adequately counseled on not just

the risks and benefits of iri the potentially alternatives of other uh...

technologies and treatments that may be of equal or better benefits

the other thing to consider is that

depending on the tumor

uh... there may be surgical or rar radiotherapy options that should also be

considered

i think that

most important thing if you go on actually going to have an army procedure

done now

is that you have it done you know with physicians who have

a pretty good track record of treating patients with uh... minimally invasive

uh... approaches

so this is a very new technology and we're very excited to be at the front

end of this because of what we think you offer patients

its approved for all soft tissue a place in by the food and drug administration

the f_d_a_

uh... and where at the start

and hopefully among the lead in looking at

types of tumor sounding liver tumors of the other soft-tissue tumors that

weekend better gavel with this

in with some of the other a place in tools that we're fair expert using once

it may be difficult to reach particular types of cancers that may be more

responsive the ability to maybe treaty cancer that's again something else

parked up close against another car where you wanna just get this and not

that

we think that this type of technology is going to give us some advantage in

treating cancer that may be up against something else that we want to save

or that other thing may make it hard to treat with other tools just 'cause it's

their so this may allow us to get right up against the edges of things

better than other tools and that's one of the reasons that we're really excited

about this
