Most PA procedures
​
For example for L PA pseudoaneurysm after gunshot
​
Can access via R CFV
​
Can use 6F long 45 cm or 60 cm sheath and can curve sheath
​
to get into Pulmonary arteries
​
use 6F Montifiore catheter
​
and use exchange length bentson
​
basically just wiggle catheter into RA and then into PA outflow tract
​
when you push the wire out, it tends to prolapse into the PA
​
actually somewhat straightfoward
​
after that can exchange over betnson for angled cath, either kumpe 65-80 or angled glidecath or glideCobra
​
remember to use all angulations to see PA better, RAO, LAO and cranio caudad angulation
​
have fun

​
did a PA AVF
RLL PA connection to draining vein leading to LA
​
whoel case like this:
R groin access, CFV
all exch length wires, long bentson
tracked 7F 50 cm or so sheath to RA
used 7F? grollman catheter to wiggle up through PA into RPA
tracked sheath over catheter
used wire at times
left wire in the rPA
used long 100 cm angled cath merit medical to select the RPA, the lower lobe and then the feeder vessel
got out as distal as possible using bentson and angled cathete
did some angiography
tracked sheath as distal as possible
got as closeto nidus as possible (where artery turns into pulmonary vein)
put big occlusion device there, large MVP4 device, which goes thru catheter
then followed it with large 035 pushable coils x 3
post embo run no flow
pulled all and left
​
thats it
​
​
PA Lysis
for intermediate risk PE
with JM
R CFV access x 2
use micrpunc upsize to 7F 55 cm sheath
use exch length everything
exch length bentson
use pigtail or grollman or montefiore to get into PA
can be difficult
watch for ectopy
once in, track sheath as close you can get into PA
do run thorugh sheath or catheter
do oblique imaging
get wire into LPA and then stick again and get wire into RPA
can switch wire for exch amplatz to track sheaths up
eventually advance infusion catheter long length over wire into PA
remove wire and place obturator into infusion caths
stich sheath into place
use steristrips to get infusion cath into place
start drips
make nice dressing for pt leg
pt to remain bedrest while drips are infusing
​
​
​
PA lysis catheter check
remember check pressures
remove unifuse over long bentson
advance and form pigtail flush into each PA
measure pressures and record
do flush angiogram of each PA
decide if to continue or not
​
​
Supplies for PA lysis:
Remember to order urinary catheter
need orders for pre, during, and post
make sure to have lytic and heparin bags ordered and obtained from pharmacy
​
think about IVCF placement
MAKE SURE TO PLACE PICC LINE DURING LYSIS; for frequent blood draws of fibrinogen
​
55 cm 7F Cook sheath x2
micropuncture kit
exch length bentson
exch length amplaz (regular stiff Green wire)
montiefiore or other PA catheter 7F
100 cm 5F pigtail catheter (can be the best PA cath actually, for nego into PAs)
100 cm 5F angled / vert catheter (merit makes one)
​
stick R CFV or R SFV twice and place two sheaths to start
​
consider dilators for access cuz of kinking at the site difficulty advancing long 7F sheaths
90 cm 10 cm infusion length Unifuse catheters
​
when doing Runs, do one AP and one 30deg LAO
​
ok to run 1 mg TPA x2 infusions catheters
ok to run 400 U heparin x2 for 2 sheaths
​
check fibrinogen q6 hrs, 150 is cutoff value
​
think about IVCF. if placing, would place initially, then drive seaths up thru
​
​
prelim checklist for PA lysis consult:
​
first off what type of PE? mild mod sev, garden variety, submassive, massive
​
massive means hypotension systolic 90 mm x 15 min or reduction in baseline pressure some ?x amount x some amt time
tachycardia
pressors can mean unstable
​
submassive means normotensive but evidence of RHstrain
​
garden variety is low risk: DVT and PE and will get better on a/c, probably as outpt
​
info you want:
cardiac enzymes: trop leak? many causes of this including MI, inflammation
cardiac echo: is there RH dysf?
EKG: is there s1q3t3? is there RBBB? is it normal abn? is there STEMI?
BNP: can be helpful if acutely up- may mean RH dysf
CTA: check RV / LV ration: if greater than 0.9: indicates RH strain. check for thrombus in situ within cava: IVCF. check for CTEPH
get a baseline DIC panel- for ddimer and fibrinogen
get arterial or venous lactate
​
is there PERT team
is there cardiology
is cardiac surgery avail
contra indication to lytics?
age - older is worser- more brain bleeds
is there recent surgery?
​
alternative to catheter based lysis is IV alteplase
can use 100 mg IV or 'half dose' 50 mg alteplase
can still do lysis afterwards
