[Clinical Information]
- Patient initials or identifier number:
C.M.
-Relevant clinical history and physical exam:
Male,72y.o, retired, was reffered to our hospital as Stabile ungina III CCS. Thepatient got positive family anamnesis for CAD with previous coronaryprocedures/ PCI/Stenting to mid.RCA and distal RCA due to inferior STEMI/2018/and PCI/Stenting to ostial LAD/also 2018, 1moth before the presenthospitalization. From comorbidities the patient got diabetes/on insulin/. Fromphysical exam with stabile cardiopulmonary status.
-Relevant test results prior to catheterization:
From non invasive methods:ECG- SR,HR-78/min,QS III,avF.From laboratory referent values of cardiospecific enzymesand other parametersEcho- referent left chamber diameter, hypokineticantero-septal and iferior wall. Dyastolic dysfunction. AR I stage.
- Relevant catheterization findings:
Angyo was done through right radial artery/6F indroducer.From Angyo:RCA –plaques, stents in m/dRCA-ok. PL- non-significant stenosis in mid part. LAD-ost. stent-okStenosis: 40% mLAD, 50% dLAD. LCx-p/m: plaques, 80% stenosis dLCx after OM2 OM1:60% ostioproximal stenosis The objective of our treatment was distal LCx.


[Interventional Management]
- Procedural step:
PCI/GC EBU 3.5/6F, GW-BMW placed in LCx. Wedid pre-dilatation with baloon 2.0/30mm. After that we tried to implant DES2,25/24mm but the stent could't pass trough LM. We tѬܬ out the stent, but onlybaloon was on the shaft. So what happened was that we passed with GW trough the strut of the ostial placed stent inLAD, that was implanded previous month and the stent we've tried to implant indLCx falled off the baloon and was stucked in the strut of ostial LAD stenttowards LM . Weve got 3 plans for resolving the situation: PLAN A -With smallbaloon trying to push the stent down, away from LM, but that was withoutsuccess, PLAN B -Triyng to crush the stent and we took Guideliner ,trying tosecure support for bigger ballon to pass and crush the stent towards LM ,butalso this was failed attempt. And bailout was PLAN C- Stent retrieval, so wetook loop snare and managed to catch the stent. We were satisfied that the jobwas finished, but we've managed only to extract the proximal part of the stent.The rest of the stent was still there, stucked in the ostium od LAD. So we takethe snare again and  this time we managedto extract the stent, but when we took out the stent we're very surprised thatin fact with the stucked LCx stent weve extirpated the ostial LAD stent. Intaking out a part of the stent fell out in front of radial sheath. We continuedtrough right femoral artery , did aortography at first/the aorta was ok/, then IVUS/LM/LCxand PCI/LCx and LAD in same act.

excellent management and final result, really the best way to deal with complication is to avoid it
in this case, there was a protrusion of struts from previous LAD stent so we can use guideliner to pass the stent distally
my question here, 1) there was any intimal laceration in LM or LAD from extracting the previous stent clarified by IVUS ?
2) You can inflate big ballon at osteal LAD and extract LCX stent to avoid peeling previous stent... is that was option?
